Four tools, two formulas mixed in the machine, under nine pounds.
Where this ends up Four named tools and two formulas that mix inside the machine, in a package under nine pounds. Its twenty-times claim is measured against Shark’s own single formula, which the footnote says plainly.
The footnote does the work, and it is printed: “*vs. Shark Deep Clean Pro”.
So the claim is that the two-part system is twenty times the one-part system from the same maker. Not twenty times a rival, not twenty times water.
And the mechanism behind it is real rather than a slogan, which is worth saying because the multiple invites dismissal:
“Unlike premixed chemicals that lose strength over time, StainStriker Technology fuses two formulas on contact.”
Peroxide-based oxidisers are the active ingredient in OXY stain removers, and they begin decomposing the moment they are diluted and sealed in a bottle. A premixed carpet solution that has sat on a shelf for six months is genuinely weaker than the same chemistry mixed at the point of use.
Mixing inside the machine is a sound engineering answer to a real chemical problem. The twenty simply has no external reference.
What a comparative claim looks like when it does: the Shark CarpetXpert at $299.95, from the same maker, footnotes its cleaning claim as “based on ASTM F2828 using included cleaning solution” — the published standard test for soil removal from carpet. That is checkable, and it is the only such citation on this shelf.
16 oz Deep Clean Pro and 32 oz OXY Multiplier in the box.
At least seven of the fourteen listings here tie you to a branded bottle, and both Sharks tie you to two:
Shark StainStriker — 16 oz Deep Clean Pro + 32 oz OXY Multiplier Shark CarpetXpert — 12 oz Deep Clean Pro + 16 oz OXY Multiplier Hoover PowerScrub — “PAIR WITH HOOVER CLEANING SOLUTION” Hoover SmartWash — “Pair with Hoover Carpet Cleaner Solution”, two trial sizes Bissell TurboClean OXY — “Pair with our most powerful formula”, two 8 oz bottles Bissell Little Green — a “triple action formula”
The exception is the Dapper at $2400, which mentions no formula at all: a “cold water extraction system” takes whatever you choose to put in it.
The difference matters because the headline claim here requires both bottles. Run it on the base formula alone and you are running a conventional spot cleaner.
And the odor claim carries the same condition: “^When used as directed with Shark cleaning solution.”
So the machine and the chemistry are one product. Budget accordingly.
Crevice Tool. 3.5” Stain Eliminator. 7” XL Stain Eliminator. Pet Mess Extractor.
Three of those are the same idea at three sizes — a seam, a spot, a larger area. The fourth is named for a task, and that is the interesting one.
A pet accident is not a surface stain. It is liquid that has soaked through the pile into the backing and sometimes the underlay, and two things decide the outcome: pulling it back up before it spreads, and removing the odor source rather than covering it.
The listing addresses the second directly: “Stubborn, lingering odors like smoke and pet urine aren’t just covered up, they’re trapped and removed.”
Pets are the stated purpose of half this shelf: the Bissell TurboClean PET at $159.99 with its “4” Self Cleanout Tool”, the Hoover PowerScrub at $169.99 with a “pet tool for stubborn messes”, the Hoover SmartWash Pet XL at $289.99, and this.
Naming all four tools also puts this ahead of the direct rival on documentation. The Bissell Little Green at $129.99 names none.
“weighs under 9lbs… it conveniently stores in cabinets or closets.”
Nine pounds is 4082 g (144 oz); the catalog publishes 3860 g (136.2 oz), which is 8.5 lb. The two agree, which is worth noting because this shelf does not always manage it.
The full range:
this 3860 g · Bissell Little Green 4377 g · Bissell TurboClean OXY 5897 g · Bissell PET 6350 g · Shark CarpetXpert 8187 g · Hoover PowerScrub 8391 g · Hoover SmartWash 9049 g · Dapper — no weight published, and 1130 × 475 × 864 mm
Those upright figures are empty, and they climb with water.
The second half of the bullet is the half that decides whether a spot cleaner gets used: it fits in a cupboard. A machine kept in a garage is fetched for a disaster; a machine in the hall cupboard is used on a spill while the spill is still wet, which is the only time any of this is easy.
326 × 294 × 381 mm is a shoebox and a half.
The listing publishes “ultra-powerful suction” and no brush roll, because a portable does not have one.
Carpet dirt is held mechanically between fibers, and water alone will not release it. Every powered machine on this shelf agitates:
Dapper — a nylon brush at 1500 RPM Hoover PowerScrub — five counter-rotating SpinScrub brushes Bissell TurboClean PET and OXY — a 4-row DeepReach PowerBrush Shark CarpetXpert — “a high-speed brushroll”
On this, the agitation is your arm pressing the tool into the pile — which is why three of the four tools are described as “stain eliminators” rather than floor heads.
The trade is clear and it is not a weakness. A portable goes where no upright can: a stair riser, the back of a car seat, the side of a sofa, a mattress. On open floor it is an hour on your knees.
No tank capacity, which is the significant omission on a portable. Only three of eight listings publish one — the Bissell Little Green at 48 oz, the Hoover SmartWash at 96 oz, and the Dapper at 10.5 and 8 gallons.
On a hand-held machine the tank decides how many trips to the sink a job takes, and the recovery tank fills first, since everything you spray comes back with the dirt in it.
No hose length. Both Hoovers publish 8 ft, the Bissell PET 7 ft, the Dapper 10 ft.
No suction figure. “Ultra-powerful suction” appears twice here and is measured nowhere. The Dapper is the only machine on this shelf publishing the professional pair — 6.5 inches of water lift and 100 CFM — which together describe how deeply it pulls water out of a pile and how fast it moves it.
No drying. Both Hoovers publish HeatForce; the Shark CarpetXpert publishes the opposite strategy, “PowerSpray penetrates deep into fibers without oversoaking them”; the Dapper heats water to 208.4 °F. Drying is the real complaint about this work, because fabric left wet smells and can grow mold — and on upholstery, where this machine will spend most of its life, that matters more than on carpet.
No warranty, which only the Dapper publishes, at two years parts and labor.
And one practical note no listing on this shelf gives: use low-foam extraction solution only. Ordinary carpet shampoo foams enough to fill a recovery tank with bubbles and carry them into the motor.

Shark’s own other formula, and the listing says so in its last line: "*vs. Shark Deep Clean Pro". So the claim is that the two-part system is twenty times the single-part system from the same maker — not twenty times a rival, and not twenty times water. The mechanism behind it is real, and worth understanding rather than dismissing: "StainStriker Technology fuses two formulas on contact". Peroxide-based oxidisers are the active ingredient in OXY stain removers, and they begin decomposing as soon as they are diluted and bottled — so a premixed carpet solution on a shelf for six months is weaker than the same chemistry mixed at the moment of use. That is the listing’s own point: "Unlike premixed chemicals that lose strength over time". Mixing in the machine is a genuine engineering answer to a genuine chemical problem. What the twenty times does not tell you is how this compares with anything else on this shelf — and the Shark CarpetXpert at $299.95 shows what a comparative claim looks like when it is footnoted properly, citing "ASTM F2828", the standard test for carpet soil removal.
It publishes considerably more, and it costs twenty dollars for that. This names four tools — "Crevice Tool, 3.5" Stain Eliminator, 7" XL Stain Eliminator, Pet Mess Extractor" — and two formulas by size. The Bissell names no tools at all and one "triple action formula". This publishes a weight, "under 9lbs", and the catalog confirms it at 3860 g (136.2 oz); the Bissell publishes none in its bullets, though the catalog gives 4377 g (154.4 oz). What the Bissell publishes that this does not is the tank: "48OZ. CLEAN WATER TANK", where this gives no capacity at all — and on a portable the tank decides how many trips to the sink a job takes. On claims, the Bissell asserts being "scientifically proven to lift and remove 100+ common messes" with no test named; this asserts a 20× multiple against its own formula, which is at least honestly footnoted. So: more tools and clearer chemistry here, a published tank there, and both ask you to do the scrubbing.
It handles volume, which is the specific problem with a pet accident. Of the four tools, three are variants of the same thing — a crevice tool for seams, a 3.5 inch head for spots, a 7 inch XL head for larger areas — and the fourth, the "Pet Mess Extractor", is the one named for a job rather than a size. A pet accident is not a stain on the surface: it is liquid that has soaked through the pile into the backing and sometimes the underlay, and the two things that matter are pulling it back up before it spreads and removing the odor source rather than covering it. The listing addresses the second directly: "Stubborn, lingering odors like smoke and pet urine aren’t just covered up, they’re trapped and removed" — with a footnote, "^When used as directed with Shark cleaning solution". Across this shelf, pets are the stated purpose of four listings: the Bissell TurboClean PET with a "4" Self Cleanout Tool", the Hoover PowerScrub with a "pet tool for stubborn messes", the Hoover SmartWash Pet XL, and this.
