Compare the picks

[gth_compare]

Example figures are manufacturer rated, as published on each listing and collected 19 October 2026.

How we scored them

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.

What the listings tell you

Suction is the headline figure: the Vacmaster 400 states 16Kpa power suction, the only suction figure in the set. Tools come next: the Shark StainStriker ships 3 tools with a self-clean function, and the Vacmaster lists versatile tools for pets, area rugs and couches. Pet formulas are the Shark’s edge: a Deep Clean Pet formula and a 12oz OXY formula in the box, with pet hair pickup stated. The WECLEAN C5 includes its deep cleaning solution, the only pick with solution in the box. The Hoover Spotless is the car detailer’s pick: a portable carpet and upholstery spot cleaner that lists car and auto detailing outright. Warranties: 3 year limited on the Shark, 2 year on the Hoover, and no term stated on the Vacmaster or WECLEAN.

Buying guide: best carpet extractor portable

Start with the job. For car interiors, the Hoover Spotless lists car and auto detailing outright, which is the use case this site cares about. For pet messes, the Shark StainStriker is built for it: pet hair pickup, pet formulas and a self-clean function that flushes the machine after the dirty work. For raw suction, the Vacmaster’s 16Kpa is the only stated figure, which makes it the paper winner on power. For a complete kit, the WECLEAN C5 includes deep cleaning solution, so you start cleaning on arrival. Then check the tools: 3 tools on the Shark against versatile tools on the Vacmaster. Self-cleaning matters more than it sounds: a spot cleaner that cleans itself gets used; one that needs disassembly after every pet accident gets shelved. For a garage that details cars and cleans up after pets, the formula is strong suction, pet tools and a self-clean function, with the longest warranty as the tiebreaker.

Suction and what 16Kpa means

Suction is the number that separates a spot cleaner from a damp rag, and the Vacmaster 400 is the only pick here that states one: 16Kpa power suction. The figure is the pressure the motor pulls, and higher suction lifts more water and dirt from the fibers in fewer passes. That matters because a portable extractor’s whole job is extraction: the spray and the brush loosen the stain, but the suction is what removes it. A weak machine leaves the carpet damp, and damp carpet re-soils faster and can smell. The other three picks do not state a suction figure, which is common: most portable spot cleaners list features instead of pressure. When you compare, treat the 16Kpa as the paper leader on power and the others as judged on their tools and formulas instead. For car interiors, where the seats are thick foam that holds water, stronger suction shortens the drying time. For a quick pet stain on a low-pile rug, any of the four has enough. The rule is simple: if suction is your priority, the stated figure beats the unstated one.

Tools, formulas and the pet question

The tools in the box decide what the machine can actually clean. The Shark StainStriker ships 3 tools, the most stated here, and the Vacmaster lists versatile tools for pets, area rugs and couches. A crevice tool reaches between car seats; a wide tool covers sofa cushions; a pet tool has the rubber nubs that pull hair from upholstery. The formulas matter as much as the hardware. The Shark includes a Deep Clean Pet formula and a 12oz OXY formula, the only pick with two formulas stated. The WECLEAN C5 includes its deep cleaning solution, the only pick with solution in the box. Pet stains are the use case that separates these machines: the Shark is built for it with pet hair pickup, pet formulas and a self-clean function, while the Hoover lists pet stain removal and the Vacmaster lists pet tools. For a household with pets, the formula is a machine with pet tools and a pet formula in the box, because buying the machine and then the formula separately is the hidden cost. The 12oz OXY formula is the stain-lifter for set-in spots; the Deep Clean Pet formula is the everyday pet-mess cleaner. Match the tools and formulas to your stains, not to the marketing.

Self-clean and maintenance

A spot cleaner that is hard to clean does not get used. The Shark StainStriker is the only pick here with a self-clean function stated, and it is the feature that matters most after suction. Pet accidents and muddy paw prints leave the machine itself dirty: tanks, hoses and tools carry the same grime the carpet gave up. The self-clean function flushes the machine after the dirty work, which is the difference between a tool that is ready for the next mess and one that sits in the garage smelling. The other three picks do not state a self-clean feature, so plan on rinsing the tanks and tools after each use. The routine is simple: empty the dirty tank, rinse it, run clean water through the hose if the machine allows, and wipe the tools. Store it with the tanks empty and the lid open so it dries. For a garage that details cars, the self-clean function is worth real money: a machine that cleans itself after a muddy interior gets used after every muddy interior, while one that needs disassembly gets used once and shelved.

Warranty and the long view

The warranty terms are the maker’s bet on its own machine. The Shark StainStriker carries a stated 3 year limited warranty, the longest here. The Hoover Spotless carries a stated 2 year warranty. The Vacmaster and WECLEAN listings state no warranty term, which is the gap to weigh. A portable extractor lives a hard life: dirty water, pet messes, car interiors, and the occasional tipped tank. The machine with the longest written warranty is the one the maker expects to survive that life. When two machines do the same job, the longer warranty is the tiebreaker. The 3 year limited term on the Shark is also the match for its feature set: 3 tools, self-clean, pet formulas, and the longest backing. The 2 year term on the Hoover is solid for a car-detailing spot cleaner. A missing warranty does not mean a bad machine, but it means the promise is not in writing. For a tool that handles the dirtiest jobs in the house and the garage, buy the function first and treat the warranty as the insurance on that function.
