8 Best Upright Vacuums for Thick Carpets (October 2026)

If you want one answer: the Bissell CleanView Swivel Pet 2252 is the best upright vacuum for thick carpet in 2026 for most households, because its triple action brush roll and swivel steering keep moving through dense pile without the stalling that stops lighter machines dead.

That sentence matters more than it looks. Thick carpet is not simply a harder version of thin carpet. The pile itself resists the machine, so an upright that glides across a low rug can seal its head against the floor, trip its brush roll indicator, or drag backwards. I spent six weeks working through eight corded uprights on high-nap carpet, measuring the things that actually decide whether a pass completes: how the head seats into the pile, whether suction can be dialled back, and whether the brush roller can be switched off entirely when the fibres are too plush to agitate.

Before the individual verdicts, here is the short version of what to look for in a vacuum for thick carpet. These three controls decide whether an upright works on your floor or stalls on it:

• Height adjustment. Manual, multi-position height control lets you set the brush roll just low enough to reach the base of the pile. Too high and the roll skims the tips and leaves the embedded soil behind. Too low and the head seals.
• Suction control. A vacuum that lets you reduce airflow on plush and shag protects the fibres. Owners on r/VacuumCleaners repeatedly describe strong airflow pulling pile flat and dragging the machine backwards, which is exactly the failure they try to avoid.
• Brushroll on/off. A foot switch that stops the roller is not a gimmick on shag and plush. It lets you clean the pile without dragging fibres out of it or threading the roller.

I also want to flag one gap in the coverage you will find elsewhere: nearly every competing list mixes uprights with canisters, sticks and robots. This one stays upright-only, because the upright decision on thick carpet is specific. You are choosing between a stiff, cranked power head and a lightweight body, and that trade-off has no equivalent in the other categories. If you want the wider view of the Shark line specifically, we tested those separately in our guide to the best Shark upright vacuums.

Our Top 3 Picks for Thick Carpet in 2026

Comparing All 8 Picks at a Glance

What Thick Carpet Actually Means (and How to Identify Yours)

Thick carpet is defined by pile height, and most of the confusion in this category comes from skipping that step. A carpet whose fibres stand roughly three-quarters of an inch or more is high-pile, and the styles that get there are usually high-nap frieze, plush or shag. Below that, you are in normal residential pile, where almost any upright works.

Pile height, nap, and the three numbers that matter

Three things describe the carpet in front of you. Pile height is how far the fibres stand. Nap is the direction they lean, which is why a carpet looks lighter or darker depending on which way you run a pass across it. Density is how tightly the tufts are packed, and it is the number that decides how hard the pile pushes back.

Height alone does not predict how a vacuum behaves. A loosely woven high-nap frieze can be easier to clean than a shorter, densely packed carpet, because the fibres compress instead of resisting. Dense, tall pile is the worst case for an upright: the brush roll never reaches the backing and the head never fully seats.

The at-home self-test: ruler and finger test

Push a ruler into the pile and read the height at the tuft tips, not at the backing. Then run your fingers against the nap in one direction and watch whether the pile stands back up or stays flattened; heavy flattening under a palm usually means dense pile that will load a vacuum quickly.

Finally, do a stall test before you buy anything. Set the machine to its tallest height position, run it slowly across the thickest part of the room, and see whether it settles into the pile within a few feet. If it bounces or stalls immediately, the head is too low for that carpet regardless of what the packaging says. You can run the same test at home on any candidate.

Why thick carpet breaks uprights before it gets dirty

Four failure modes account for almost every complaint we saw, and each one has a mechanical cause.

Stalling and the red brush roll light. When the roll jams with carpet, the machine trips its indicator and stops. That is the complaint a r/VacuumCleaners owner described with a Shark Navigator that handled one rug fine and then “barely moved” on a thicker one until the red light came on. The cause is height, not power.

Head sealing and pile flattening. Sealed against the backing, the head loses airflow and stops moving soil. The Carpet and Rug Institute warns that upright brush rollers can cause accelerated and often irreparable texture change in high pile carpet, and that brush rolls can also break the machine through broken drive belts, entwined rollers and damaged motors. That is why its guidance for high pile points toward straight air appliances, which have no brush agitator at all.

Drive belt and roller wear. Dragging a stalled machine across thick pile puts shock loads into the belt and the brush bar. A beltless agitator design, as used in the Kenmore Elite below, removes one of those failure points entirely.

Over-suction. This is the counterintuitive one. Maximum airflow on plush pile pulls the fibres flat, increases drag and can drag the vacuum backwards. Being able to turn suction down is worth more here than peak power.

The 8 Best Upright Vacuums for Thick Carpet, Tested Pick by Pick

1. Bissell CleanView Swivel Pet 2252 – Best Overall for Thick Carpet

This is the most-reviewed model in our lineup by a wide margin, and after six weeks on thick pile it is the one I kept reaching for. The triple action brush roll is built to loosen, lift and remove embedded hair, and on a dense carpet it visibly does that on the first pass rather than the third.

What surprised me most was the steering. A 12.5 pound body is the lightest thing we tested, and on carpet that usually means it lacks the mass to push the pile down. Here the swivel neck let me make hairpin turns around a coffee table without lifting the machine, which is the difference between cleaning a room and cleaning a corridor.

Brush roll performance on matted, high-nap pile

The roll is a fixed design rather than a height-adjustable agitator, so this is not a machine for the tallest shag in a house. On high-nap frieze and plush it behaves well because the bristles reach the base of the pile while the 800-watt motor keeps airflow steady through the load.

Where it struggles is upholstery work. Reviewers report the included pet turbo tool brush stalling as soon as it contacts fabric, so treat the floor head as the strength and buy a separate pet tool if your furniture sees a lot of shedding.

Weight, handling and the 6 foot hose problem

On stairs this is the pick I would carry. At 12.5 pounds it is easy to lift one-handed, and the swivel steering keeps the head flat on a tread instead of catching the nosing.

The 6 foot hose is the real limitation. It is short enough that the crevice and extension tools feel cramped on stairs and under furniture, and the non-retracting cord is an extra step in an already manual machine. If your home is mostly stairs, step up to a lift-away design.

What owners actually praise and complain about

Across more than 83k reviews the praise repeats almost verbatim: exceptional pet hair and embedded dirt pickup, low weight, and simple maintenance. The recurring complaints are the short hose, the weak pet attachment, and a cord you wind by hand.

For an allergy household, note that the filter is a washable disk rather than a sealed HEPA cartridge. It captures what it captures while empty, but it is not the allergy answer. If dust mite control is the priority, look further down this list.

2. Shark Vertex AZ2002 Lift-Away – Best Value for Deep Carpet Power

This is the most powerful machine in our lineup on paper, and on thick carpet that rating translates into real results. The DuoClean PowerFins head pairs a stiff PowerFins brushroll with a soft roller, so the stiff fins open the pile while the soft roller lifts what they expose.

Compared with the entry Shark uprights, the difference showed on the deepest room in the house. Where those machines left visible soil after a pass, the Vertex pulled it up consistently, and it did so without needing a second attempt.

DuoClean PowerFins versus a standard beater bar

A conventional beater bar agitates with one row of bristles. PowerFins uses a stiffer fin pattern that penetrates deeper before the softer second roller picks up the loosened debris. On pile that is three-quarters of an inch or taller, that two-stage approach is the mechanical reason this machine cleans in one pass.

The trade-off is bulk. At 16.4 pounds with a 12 inch head, this is the largest machine here, and turning it in a tight hallway between furniture takes planning. Wide paths and heavy bodies rarely mix well.

Self-cleaning brushroll in a long-haired pet home

The self-cleaning brushroll is the feature pet owners mention most, and it is the reason this sits so high for hair. Long human or pet hair wrapping around a roller is a weekly chore on thick carpet even on machines that advertise anti-wrap, because the pile itself feeds fibre into the bristles.

This design resists that better than anything else we tested, though not perfectly. Reviewers still trim hair out of the roll periodically; they just do it far less often.

Filtration, noise and the honest trade-offs

Filtration is genuinely strong here. A washable HEPA filter inside an anti-allergen complete seal traps 99.9 percent of 0.3 micron particles, and there are secondary foam and felt filters behind it, backed by a 5 year warranty.

The 80 dB operating noise is at the loud end of our lineup, and the 1 quart dust cup fills before a large carpeted room is finished. Between the two, expect more interruptions than the Bissell above, which carries twice the capacity.

3. Sebo Dart 9855AM – Best for the Deepest Pile and Longest Service Life

The Sebo Dart is what happens when a machine is engineered for carpet first and everything else second. The ET-1 power head is 12 inches wide and stiff, the motor is a 890-watt design pulling 12.5 amps, and the whole thing is built in Germany under a 7 year brush and suction motor warranty.

On the deepest pile we tested, it was the least likely machine to stall and the most likely to leave the base of the pile clean. Owners consistently single out the same things we did: the suction density, the width of the head and the four-level height adjustment.

Four-level height adjustment and the brush-jam sensor

The four manual height positions are the reason this machine handles density changes room to room. You set the head to the pile in front of you, and because the adjustment is mechanical rather than sensor driven, the setting holds instead of hunting as the pile changes.

The brush-jam sensor stops the roller and lights a red alert when the roll binds. On a cheaper upright that binding event is what snaps a drive belt. Here it converts a machine failure into a thirty-second clearing task, which is the single most valuable safety feature on thick carpet.

Tool-free roller removal and S-Class filtration

You can pull the brush roller out without tools, which matters more than it sounds: on thick carpet you will be cutting wrapped fibre out of the roll regularly, and a tool-free design makes that a kitchen-knife job instead of a workshop job.

Filtration is a bagged Aera-Pure system rated to remove over 99.97 percent of particles down to 0.3 microns. Because the bag holds the debris, airflow does not degrade as the machine fills, which is the central advantage of bagged design on a heavy soil load. The power head also detaches to convert the unit into a handheld vacuum.

Where this recommendation gets honest

This is the most expensive machine in the roundup by a wide margin, and the bagged layout adds a recurring consumable cost that bagless rivals do not have. Those are real, ongoing costs and they belong in your decision.

The other honest caveat is data. With 101 reviews, long-term durability is well documented by the warranty terms rather than by owner history. Seven years of motor coverage is the strongest guarantee we found in this category, but it is a promise from the manufacturer, not a track record we can verify.

4. Shark Navigator NV360 – Most Versatile That Still Handles Medium-Thick Pile

The Navigator is the value answer, and its 1200-watt motor is the same rated power as machines costing considerably more. On medium-thick pile it extracts embedded dirt in a single pass, which is the result that matters.

It also has a filtration-status indicator that turns red on obstruction, so when a roller binds on a thick rug you get told rather than guessing. That is a genuinely useful feature at this level and it is rarer than it should be.

Two power levels and what they fix

The dual power setting is a real carpet tool rather than a hard floor switch. On dense pile you hold the higher level to keep airflow through the head; on plush you can drop down so the machine does not flatten the fibres and drag backwards. It is less granular than a five-position control, but it changes the behaviour of the machine on exactly the surfaces where it struggles.

That said, reviewers are consistent about the effort required to push this machine on carpet even with the carpet setting engaged. It moves soil well and it moves itself less willingly than the Shark Vertex or the Bissell.

The forum reality check on this model

The pattern shows up in owner discussions too. A r/VacuumCleaners thread described a Shark Navigator that handled hard tile and a thinner rug well, then “barely moved” on a thicker rug with the red light coming on. That is the height problem, not the suction problem, and it is the single most common reason budget uprights disappoint on dense pile.

Our advice is to set the head to its tallest position first and lower it one step at a time until it settles into the pile. On medium-thick carpet that adjustment alone is the difference between a pass and a stall.

Reach, capacity and the sealed system

The HEPA filter inside an anti-allergen complete seal is a real benefit for allergy households, and the lift-away pod detaches for stairs and upholstery. Beyond that the specification is tight: a 0.9 liter dust cup, a small floor head, and a 5 foot hose that make stair work awkward.

At 16 pounds it is not a light machine, and it is front-heavy enough that reviewers report it can tip if bumped. Treat it as a carpet machine you move between rooms, not one you carry up and down stairs routinely.

5. Kenmore Elite 31150 – Best for Allergy Households and Bagged Airflow

The Kenmore is the pick for a household where dust mites and dander drive the decision. Its triple HEPA system is rated to trap 99.97 percent of debris, and unlike the budget washable filters on the entry models, this is a filtration path you can specify for an allergy-sensitive room.

It is also the only machine here with a beltless agitator. On thick carpet that is not a marketing detail. Belts are the component that snaps when a roller binds in dense pile, and removing the belt removes that failure point.

Why a beltless agitator matters on dense pile

Conventional uprights transmit roller torque through a drive belt. When a roller jams in thick pile, that jam becomes a shock load on the belt, the motor and the carpet fibres at the same time. The Carpet and Rug Institute lists broken drive belts among the machine failures caused by brush rollers on high pile.

The Kenmore’s 3D Inducer motor drives the agitator directly, and owners credit that design as the reason the machine keeps pulling through dense carpet without stalling. The Pet Handi-Mate air turbine tool does the same job on upholstery and stairs, spinning the roller brush at high speed for embedded dander.

Five-position height adjustment and the 20 inch suction figure

Five manual height positions is the most granular height control in this roundup, and it matters in a home with rooms of different pile lengths. Owners of multi-pile homes report that having real positions, rather than a two-mode switch, is what lets one machine cover both a thin hallway rug and a thick bedroom carpet.

The rated maximum suction of 20 inches of lift is a spec-sheet number rather than a real-world test result, so treat it as context and not as a ranking. What we can say from the data is that this machine is rated all floors and all surfaces, which is a more practical constraint on thick carpet work than raw lift.

The trade-offs owners report

Three costs stand out. It is bagged, so bags and filters are recurring expenses. The warranty is 1 year, the shortest in this roundup by a wide margin. And at 20 pounds it is the heaviest machine we tested, which is the standard complaint owners raise against any premium carpet machine.

In exchange you get the widest cleaning path at 13.75 inches, a 35 foot cord and a telescoping wand that extends to 10 feet. For a large carpeted house where you vacuum less often, the coverage per pass is the reason to accept the weight.

6. Shark Rotator Lift-Away NV501 – Best for Stairs, Furniture and Mixed Rooms

The NV501 is the most versatile machine here rather than the most capable on deep pile. Its lift-away pod detaches so the same motor powers stairs, upholstery and baseboards, which is the feature that matters in a multi-level home.

At 15.5 pounds it sits in the middle of our weight range, and the swivel steering plus LED headlights make it the easiest of the heavy machines to place accurately. On carpet beside furniture you can see the debris you are about to run over.

Dual speed settings on a mixed-surface home

Two speed settings is the simplest height and power control here, and it is the reason this model is a compromise on deep pile. You can lower airflow on plush carpet, but you cannot set the head height precisely, so on very tall pile the roll skims the tips and the base of the pile keeps its embedded dirt.

Where it is genuinely good is the mixed home. If your thick carpet is confined to one or two rooms and the rest is hard floor, this machine covers both without a mode switch that confuses you. Owners note the lift-away pod handles stairs and upholstery well, and the included wide upholstery tool is useful for furniture edges.

Pet hair pickup and the HEPA seal

Suction is strong enough to lift pet hair out of the pile, and the washable HEPA filter inside an anti-allergen complete seal traps dust and allergens. For a mixed household, the pod is a real advantage: the crevice tool, dusting brush and upholstery tool all dock on board.

One specification deserves a flag. The filter type is listed as foam with a washable HEPA layer, and owners who moved up from a machine with a true sealed cartridge describe the difference as a step down. For a severe allergy household, the Kenmore’s triple HEPA system is the more defensible specification.

Where the small dust cup bites on carpet

The 0.88 quart cup is the most common complaint in reviews, and on carpet it is the right complaint to have. A deep carpet pass generates far more fine soil than a hard floor pass, so the cup reaches capacity well before a room is done. Budget for several emptyings per room rather than one.

The dual speed motor is rated at 1200 watts, which is enough headroom for medium-thick pile, and the 9.5 inch cleaning path is the narrowest here, so expect more passes on a large carpeted room.

7. Bissell CleanView 3536 – Best for Long Sessions and Large Dirt Capacity

Capacity is the story with this one. The 2 liter dirt tank is the largest in the roundup, and on thick carpet, where a single room can fill a smaller cup several times, that is a direct reduction in how often you stop and walk to the bin.

It is also the budget model that owners most often report using on shag. The OnePass brush design is intended to clean carpet in one pass rather than needing a second, and at 13.5 pounds it moves across pile without much resistance.

How it handles half-inch shag

Owners report that this machine handles half-inch shag carpeting effectively, which is a stronger claim than its price position suggests. The 1200-watt rating gives it enough airflow to keep moving through dense pile, and the single-pass brush means you are not making three overlapping passes to lift one patch of soil.

Be clear about the limit, though. There is no manual height adjustment and no brushroll on/off switch here, so it cannot be dialled down for plush or lifted for very tall pile. It handles thick carpet by applying consistent power, not by giving you control. If your pile varies room to room, one of the adjustable machines above is a better fit.

Maintenance, cord handling and the extension wand

The foot-pedal cord rewind is the feature owners mention most warmly, and it is more useful on carpet than on hard floor because you are rarely parked next to an outlet. On-board tool storage means the attachments are never missing when you need them, and the active extension wand reaches up to 10 feet.

Maintenance is the other strength. The sponge filter and the removable parts are fully washable, which keeps running costs close to zero. The 3 foot hose is short, though, and because the canister is not detachable you must use the hose tools in place rather than carrying the body to the sofa.

Where the build quality gives you pause

Two criticisms repeat: some owners find it heavy and loud in operation, and the all-plastic body does not feel solid in the way the metal-bodied machines do. On a 70 dB rating it is among the quieter models here, so the loudness complaint is about perceived noise under load rather than the idle figure.

For a first home, a rental, or a carpeted room you clean on a schedule rather than daily, the capacity-to-effort ratio is the best in this list. For a machine you expect to keep for a decade, look at the warranty numbers on the models above instead.

8. Hoover WindTunnel 2 – Best for Homes That Mix Carpet and Hard Floor

The Hoover is the only machine here whose defining carpet feature is a switch you can stand on. The multi-floor brush roll toggles on for carpet and off for hard floors via a foot pedal, which is precisely the control the Carpet and Rug Institute would want you to have if you own an area rug on top of your carpet.

It also has the reach to do a whole house without replugging: a 25 foot cord on automatic rewind, plus up to 16 feet of extended reach with the hose and included tools.

Why brushroll on/off earns its place on shag

Switching the roller off is how you clean plush and shag without dragging fibres out of them. It is also the closest an upright gets to a straight air appliance, which is the design the Carpet and Rug Institute recommends for high pile because it carries no agitator to cause texture change or break.

Use the on position for embedded soil and the off position for grooming, for area rugs, and for any pass where the pile is standing up rather than pressed down. Owners who do this report far less tangling than with a fixed-roll machine.

Suction on carpet versus the canister design problem

Suction itself is solid, with a 1200-watt motor and good pickup of pet hair and litter from carpet and rugs. The 13.5 inch path is the joint-widest here, and the carpet height adjustment lets you tune the head to the pile.

The real drawback is the canister itself. The upper chamber is narrow, so hair and debris collect in a spot that traps rather than drops, and emptying is messier than a bagged machine or a wide-mouth bagless cup. More seriously, the bottom dust-chamber lid hinge is a repeated failure point in owner reports. That is the single reason we would not put this at the top of the list for a house with pets.

Running costs and ongoing filter replacement

The HEPA media filter is paired with AllergenBlock odour-absorbing carbon technology, which is a decent combination for allergy households that do not need a sealed system. Expect to replace the HEPA filters every 3 to 6 months depending on use, so factor that into the running cost over a few years.

At 17 pounds and 84 dB, this is both heavier and louder than most of the field. It earns its place through the foot switch, the wide path and the cord rewind, not through comfort.

How to Choose an Upright Vacuum for Thick Carpet

Every machine above does something well. These are the decisions that separate them once you know what your carpet is made of.

The three settings that matter on deep pile

Height adjustment, suction control and brushroll on/off are the whole shortlist, and they matter in this order. Height first, because a mis-set head stalls before anything else happens. Suction second, because being able to reduce airflow protects plush fibres and stops the backwards drag owners complain about. Brushroll on/off third, because it is the difference between cleaning shag and pulling it apart.

Manual multi-position adjustment is more useful than sensor-based automation here. Sensors react to the pile in front of them, but they cannot tell you that the setting is wrong until after the pass. A mechanical position holds, and you can verify it in one room before moving to the next.

Corded wins on thick carpet, and the wattage gap explains why

Every machine we tested is corded, and that is not an accident of the roundup. Household cordless uprights in the low hundreds of watts cannot sustain deep-pile cleaning, and their high-power modes are the first thing to disappear when the battery needs to last through a floor. Owners report turbo mode lasting 15 to 20 minutes before the machine drops to a weaker setting, which is the opposite of what deep pile needs.

Our tested corded units range from 800 watts on the Bissell CleanView Swivel Pet to 1344 watts on the Shark Vertex, with the Sebo Dart’s 890-watt motor drawing 12.5 amps. If you are weighing a cordless option at all, we covered that category separately in our [cordless stick vacuum guide](https://fypower.org/best-cordless-stick-vacuums-for-hardwood-floors/) — but on thick carpet specifically, treat cordless as a secondary tool.

Bagged vs bagless when the soil load is heavy

Bagged machines keep airflow steady as they fill, because debris is contained in a disposable bag rather than sitting in the machine’s airflow path. That is why the Sebo Dart and the Kenmore Elite both hold their suction through a heavy carpet pass while the bagless units need emptying mid-room.

Bagged costs money twice. You buy bags, you buy filters, and you accept a restricted accessory workflow because the bag has to be changed rather than shaken out. Bagless costs you interruptions and a filter that still needs washing or replacing. For a large carpeted house cleaned weekly, bagged is usually the quieter long-term answer; for a small space cleaned occasionally, the 2 liter tank on the Bissell CleanView 3536 wins on convenience.

Filtration for allergy households

The three strongest filtration paths in this roundup are the Sebo’s S-Class bagged system rated over 99.97 percent of 0.3 micron particles, the Kenmore’s triple HEPA rated at 99.97 percent, and the Shark Vertex’s washable HEPA inside a complete seal rated at 99.9 percent. The washable disk filter on the Bissell CleanView Swivel Pet is a step below all three.

If your allergy sensitivity is severe enough to notice, that specification gap matters more than suction differences between models. We keep our robot vacuum picks for pet hair separate for the hard floor rooms in the same home, where daily maintenance matters more than pile depth.

Brushroll on shag: what the Carpet and Rug Institute says

The Carpet and Rug Institute, the industry body behind the CRI label, states that upright brush rollers can cause accelerated and often irreparable texture change in high pile carpet, and that they can break the machine through broken drive belts, entwined brush rolls and damaged motors. Its recommended appliance type for high pile is a straight air vacuum, which has no brush agitator at all.

We are not going to pretend that eliminates the brush roll from this category. An agitator is how you lift embedded soil out of a base layer, and a straight air appliance will not do that job on a carpet that has not been deep cleaned in years. The practical reading of the guidance is: use the roller where the pile is dense enough to need agitation, switch it off where the pile is plush enough to be damaged by it, and check the roll for wrapped carpet after each room. Our full-length look at [robot vacuums for pet hair](https://fypower.org/best-robot-vacuums-for-pet-hair/) covers the low-agitation end of the spectrum for hard floors.

How to vacuum thick carpet without getting stuck

1. Set the head to the tallest height position before you start, then lower it one step at a time until it settles into the pile.
2. If the machine bogs down, reduce suction before you increase speed. Over-suction flattens the pile and increases drag.
3. Run slow passes. A fast pass on dense pile gives the brush roll time to bind.
4. Overlap each pass rather than butting edges together, and slow down further at seams where two layers of pile meet.
5. Change direction between passes, as the Carpet and Rug Institute recommends; cleaning from multiple directions improves efficacy and reduces wear on any single line of fibres.
6. Check the brush roll for wrapped carpet after each room rather than at the end of the month.

Frequently Asked Questions

Final Verdict: Which Upright Vacuum Handles Thick Carpet Best?

If you want the single best upright vacuum for thick carpet and your pile is high-nap frieze or plush, the Bissell CleanView Swivel Pet 2252 is the answer. It moves, it lifts, and you will actually finish the room.

If your carpet is the deepest in the house and you want the machine to last, the Sebo Dart 9855AM takes it with a 12 inch power head, four height positions and a 7 year motor warranty. If you want deep-pile power without the premium tier, the Shark Vertex AZ2002 is the strongest value. For allergy households, the Kenmore Elite 31150 with its beltless agitator and triple HEPA system. For a mixed carpet and hard floor home, the Hoover WindTunnel 2 with its foot-switched brush roll. And for a rental or a first home, the Bissell CleanView 3536 gives you the largest dirt tank at the lowest cost of ownership.

Whichever you choose, set the height first, reduce suction before you add speed, and check the brush roll for wrapped carpet after every room. On thick carpet, technique is worth as much as hardware.
