Everyone in this category says they tested twenty vacuums. We have not tested any, and we say so. What we do instead is read the manuals, compile the published specifications, and work out what each machine costs to run for three years — the method is written out in full.

Bissell for tank capacity and self-cleaning tools. Hoover for brush count and warranty length. Bissell publishes a full gallon on three of its uprights against Hoover's half gallon on two of theirs. Hoover publishes five counter-rotating brushes on the PowerScrub and a five-year warranty on the SmartWash, both category-leading. Neither brand wins outright.
Where Bissell genuinely leads
Tank capacity. The TurboClean 3952, the TurboClean PET 3948 and the TurboClean Pet XL 3746 all publish a full gallon of clean tank. Hoover's PowerDash Pet and SmartWash Pet both publish half a gallon. That is double the water per trip to the sink, and on a whole floor it is the single biggest difference between the two brands.
Self-cleaning tools. Bissell publishes a 4-inch self-cleanout tool on the 3948 and the HydroRinse self-cleaning hose tool on the Little Green line. Hoover publishes a hose rinse tool on the CleanSlate Plus but not across its uprights. On a machine used for pet messes, the tool that flushes itself is what keeps the machine usable.
Formula ecosystem breadth. Bissell publishes Pro Max Clean + Protect, Pet Pro Oxy Urine Eliminator and the Little Green formula, and ships two formulas in the box with several machines. That is a genuine convenience — and a genuine lock-in, which cuts both ways.
Where Hoover genuinely leads
Brush count on the PowerScrub Deluxe. Five counter-rotating SpinScrub brushes attacking the pile from multiple angles, against Bissell's four-row DeepReach on the TurboClean line. Bissell's ProHeat 3588F answers with dual counter-rotating brushrolls, which is a different and arguably better approach, but on the mid-range machines Hoover has the brush advantage.
Warranty. Hoover publishes 2 years on the PowerScrub Deluxe and 5 years on the SmartWash Pet. Bissell does not publish a warranty length on any of the carpet cleaners on this site. On a machine full of pumps, seals and heaters, five years is a substantial thing to put in writing.
Auto Mix. Hoover publishes automatic solution metering on both the PowerScrub Deluxe and the SmartWash Pet. It removes the guesswork that otherwise wastes formula and leaves residue in the carpet — a small feature that saves money on the exact consumable that costs the most.
Automatic operation. The SmartWash Pet's motion-sensing design — push forward to clean, pull back to dry, no trigger to hold — is genuinely easier over a whole room, and Bissell publishes nothing equivalent.

01 · Best for pet messes
Bissell TurboClean PET Upright Carpet & Upholstery Cleaner (3948)
The 3952 plus a 7-foot hose and a self-cleanout tool — and the tool is what makes it usable on stairs and a sofa.
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+The self-cleanout tool rinses itself in one press, which is the single most annoying job on any extractor
+7-foot hose reaches a full flight of stairs from the landing
+Same 1-gallon tank and 4-row brush as the cheaper 3952
Where it stops
−19.2 lb, nearly three pounds more than the 3952
−Still no heater
−Pet formula costs more per bottle than the standard version
Who it is for
Pet households where the messes are on stairs, sofas and pet beds as much as the floor.
Skip it if
You only ever clean flat open carpet. The hose and tools are the entire price difference and you would never unclip them.

02 · Most brushes for the money
Hoover PowerScrub Deluxe Carpet Cleaner
Five counter-rotating brushes, dual tanks, an 8-foot hose and a two-year warranty — the most complete kit at this price.
8 feet, with upholstery, pet and crevice tools and a storage bag
Mixing
Auto Mix — meters the water-to-solution ratio automatically
Warranty
2-year limited
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+Five brushes attack pile from multiple angles rather than one
+Auto Mix removes the guesswork that wastes formula and leaves residue
+8-foot hose with three tools and a bag to keep them in
+2-year warranty
Where it stops
−18.5 lb and a wide 21.9-inch body — awkward on stairs and in a closet
−Five brushes means five things to clear hair out of
−Hoover formula is a permanent consumable, same as Bissell's
Who it is for
Whole-house carpet plus stairs and upholstery, where one machine has to do everything.
Skip it if
You want the lightest thing that works. This is the most machine on the page and the weight is the price of that.

03 · Best heated cleaner
Bissell ProHeat 2X Revolution Pet Pro Plus (3588F)

Machine weight
Not published in a comparable form on the listing
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+Dual counter-rotating brushrolls double the agitation of the single-brush machines
+A published drying-time claim, which almost nobody in this category makes
+Built-in pre-treater means you are not carrying a spray bottle around as well
+8-foot hose, the longest here
Where it stops
−Two formulas included means two formulas to keep buying
−The most expensive machine on this page
−Bissell does not publish a comparable machine weight for this model
Who it is for
Households with recurring pet accidents, where the same spots get cleaned repeatedly.
Skip it if
You clean carpets twice a year. This is a machine that repays frequent use; for occasional deep cleans, renting is the better arithmetic.

04 · Longest warranty
Hoover SmartWash Pet Automatic Carpet Cleaner
Push to clean, pull to dry, no trigger to hold — and a five-year warranty, which is the longest published on this site by three years.
Motion-sensing: push forward to clean, pull back to dry. No trigger
Brushes
FlexForce Pet PowerBrushes, odor-resistant

Warranty
5 years
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+A 5-year warranty is an unusual thing to publish on a machine full of pumps and seals, and it is worth real money
+No trigger to hold is a genuine relief over a whole room
+Spot Chaser pre-treat wand is detachable and useful on its own
Where it stops
−0.5-gallon tank on a 20.5 lb machine is the worst capacity-to-weight ratio here
−The tall 43.5-inch body needs proper storage height
−Automatic operation means less control over a stubborn patch
Who it is for
Buyers who value the warranty and hate holding a trigger.
Skip it if
You have a lot of open carpet. A half-gallon tank on a big floor means constant refills, and the Hoover PowerScrub Deluxe holds twice as much.

Bissell TurboClean Upright Carpet Cleaner (3952)
A 1-gallon tank and a 4-row brush at 16.3 lb — the cheapest full-size extractor that is not a compromise on the part that matters.
Designed around Bissell Pro Max Clean + Protect with StainProtect — an ongoing consumable
Above-floor tools
Not included on this model
Cleaning path width
Not published
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+1-gallon tank at the bottom of the price band, which is what saves the sink trips
+4-row brush is the same agitation as the dearer TurboClean models
+16.3 lb is manageable up a flight of stairs, unlike the 23 lb XL
+Bissell formula is stocked in ordinary supermarkets, not just online
Where it stops
−No hose and no above-floor tools — carpet and rugs only
−No heater, so it relies on the temperature of the water you pour in
−The formula is a permanent running cost
Who it is for
Flat carpet and area rugs in a small-to-mid home, on the lowest sensible budget.
Skip it if
You need to clean stairs or upholstery. There is no hose on this model; the 3948 PET adds one and that is the whole reason it exists.

Formula
Hoover carpet solution — an ongoing consumable; sample included
Every figure above is the manufacturer's own published number. Where a manufacturer publishes nothing, the row says "Not published" rather than an estimate.
What the numbers say
+12.5 lb, nearly four pounds lighter than the cheapest Bissell upright
+Antimicrobial brushroll, which is Hoover addressing the smell problem at the source
+Small enough to store in an apartment closet
Where it stops
−0.5-gallon tank is half the Bissell uprights' — twice the sink trips
−1-year warranty against Bissell's 2-year on the ProHeat line
−No above-floor hose on this model
Who it is for
Apartments, condos and RVs — Hoover's own stated use case, and an accurate one.
Skip it if
You have a lot of carpet. The half-gallon tank turns a big room into a refill exercise, and the Bissell 3952 costs about the same.

How to actually decide
Large carpeted floor? Bissell, for the gallon tank. Fewer trips to the sink is the difference you will notice weekly.
Want the longest published warranty? Hoover SmartWash Pet, at five years. Nothing else on this site comes close.
Pet accidents specifically? Bissell, for the self-cleaning tools that stop the machine smelling.
Hate holding a trigger? Hoover SmartWash Pet's motion-sensing operation, and accept the half-gallon tank.
Want the most brushes for the money? Hoover PowerScrub Deluxe, with five counter-rotating SpinScrub brushes.
What we cannot tell you
Which brand cleans better. Neither publishes a test against a common standard, both make claims against unnamed competitors, and we have not run either. Everything above compares published capacity, weight, brush design, tools and warranty — which is a genuine comparison of what you are buying, and is not the same thing as a performance verdict.
Common questions
Is Bissell or Hoover better for carpet cleaning?+−
Neither wins outright on published specifications. Bissell leads on tank capacity — a full gallon on three uprights against Hoover's half gallon — and on self-cleaning tools. Hoover leads on brush count and warranty, publishing five counter-rotating brushes on the PowerScrub and five years on the SmartWash.
Which brand has the bigger water tank?+−
Bissell. The TurboClean 3952, 3948 and 3746 all publish a full gallon of clean tank; Hoover's PowerDash Pet and SmartWash Pet publish half a gallon. Hoover's PowerScrub Deluxe is the exception at 3.8 liters.
Which carpet cleaner has the longest warranty?+−
The Hoover SmartWash Pet, at a published 5 years — the longest on this site by three years. Bissell does not publish a warranty length on any of the carpet cleaners reviewed here.
Do Bissell and Hoover machines need their own brand of solution?+−
Both are designed around their own formulas — Bissell's Pro Max Clean and Pet Pro Oxy, Hoover's carpet solutions. That is convenient and it is lock-in, and it is the largest ongoing cost of owning either machine.
Does more brushes mean better cleaning?+−
More agitation, in principle, and more things to pull hair out of in practice. Hoover's five counter-rotating SpinScrub brushes and Bissell's dual counter-rotating DirtLifter brushrolls are different approaches to the same goal, and neither publishes a test that lets you compare them.
