Cordless handheld carpet cleaners promise one thing: grabbing a spill the moment it happens, without dragging out a full-size machine. After comparing eight of the most popular models, the Uwant Portable Carpet Cleaner stands out as the best overall pick thanks to its 18KPa suction and strong performance on both carpet and car upholstery. The Shop-Vac 3-in-1 Cordless Spot Cleaner earns attention for its rolling brush and spray system that rivals corded machines, while the BISSELL Little Green Mini Cordless (4015) is the easiest option for quick, everyday messes. The main tradeoffs in this category come down to battery runtime versus suction power, tank capacity versus weight, and price versus attachments. Budget cordless models sacrifice deep-cleaning muscle, while premium ones blur the line between spot cleaner and mini extractor. Keep reading for the full breakdown of what each model does well, where it falls short, and which one matches your mess profile.
Key Takeaways
- Suction specs are advertised inconsistently across brands — Uwant‘s 18KPa rating translated into visibly better stain extraction than models listed at 6.5KPa, but runtime dropped, making suction the single biggest differentiator in this lineup.
- True cordless freedom costs cleaning power: the three cordless BISSELL and Vacmaster units handled fresh spills well but struggled with set-in stains that the higher-powered Uwant and Shop-Vac removed more easily.
- Spray-and-brush systems (Shop-Vac, Uwant) outperformed suction-only designs (HAUSHOF) on dried messes because loosening the stain matters as much as lifting it.
- Tank size, not weight, is the real portability limit — small tanks under 300ml mean refilling mid-job, which undermines the grab-and-go appeal of a cordless cleaner.
- The corded BISSELL Little Green 1400B and Hoover CleanSlate Plus still beat every cordless model on deep stains, so shoppers should only pay the cordless premium if convenience genuinely outranks raw cleaning power for them.

More Details on Our Top Picks
BISSELL Little Green Multi-Purpose Portable Carpet Cleaner, 1400B
The BISSELL Little Green 1400B remains the benchmark for portable spot cleaning, and it earns the top spot for one reason: proven suction paired with a genuinely useful 48oz tank. Compared with the Vacmaster 600 Series, it gives up cordless freedom but delivers more consistent cleaning power because it never runs out of battery mid-mess. The HydroRinse self-cleaning tool is a small feature that saves real time — the Vacmaster’s hose cleaning tool is more manual. Families dealing with recurring pet accidents will appreciate fewer refill trips than the smaller Hoover CleanSlate Plus. The tradeoff is honest: this is a c corded machine, so buyers who specifically want cordless convenience should look elsewhere in this lineup.
Pros:- 48oz tank supports long cleaning sessions without refilling
- Strong, reliable suction for pet stains and odors
- HydroRinse self-cleaning tool simplifies hose maintenance
- Purchases support BISSELL Pet Foundation rescue efforts
Cons:- Corded design limits where you can clean
- Not powerful enough for deep, whole-carpet cleaning
- Stubborn set-in stains often need multiple passes
Best for: Pet owners and families who clean frequent stains on stairs, carpets, and car interiors and prioritize suction power over cordless convenience
Not ideal for: Buyers who specifically need cordless operation for cars, garages, or outdoor use — this model requires a nearby outlet
- Brand:BISSELL
- Model Number:1400B
- Tank Capacity:48 oz
- Power Source:Corded (plug-in)
- Included Tools:3″ Tough Stain Tool, HydroRinse Self-Cleaning Tool
- Cleaning Formula:Trial-size formula included
- Warranty:1 year limited
Our verdict“This is the pick for households that want dependable spot-cleaning muscle and don’t mind plugging in.”
Hoover CleanSlate Plus Portable Carpet and Upholstery Spot Cleaner
Where the Hoover CleanSlate Plus separates itself from the BISSELL Little Green is tool variety. The TightSpot tool reaches crevices the Little Green’s single 3-inch tool can’t, and the 7-inch WidePath tool covers larger spills faster — effectively giving you two cleaners in one body. The dual tank system keeps clean and dirty water separate, matching the HAUSHOF’s design but with far greater capacity. The tradeoff: its 40oz tank is smaller than the Little Green’s 48oz, and it’s locked into Hoover-brand solutions for best results, which adds recurring cost. Like the BISSELL, it’s corded, so it sits lower in this roundup for buyers who genuinely need cordless portability.
Pros:- Two specialized tools cover both wide spills and tight crevices
- Dual tank system keeps clean and dirty water separate
- Dedicated hose rinse tool for post-cleaning maintenance
- Lightweight and easy to carry between rooms
Cons:- Performs best with Hoover-brand solutions, adding ongoing cost
- 40oz tank means more refills than the BISSELL Little Green
- Corded design restricts cleaning to outlet-adjacent areas
Best for: Detail-oriented cleaners who alternate between wide spills on upholstery and stubborn stains in crevices, corners, and car interiors
Not ideal for: Buyers wanting cordless freedom or those unwilling to buy Hoover-proprietary cleaning solutions
- Type:Portable spot cleaner
- Cleaning Areas:Carpet and upholstery
- Tank Capacity:40 oz
- Tank System:Dual tank (clean/dirty separation)
- Included Tools:7″ WidePath tool, TightSpot tool, hose rinse tool
- Power Source:Corded (plug-in)
- Solution Compatibility:Hoover cleaning solutions
Our verdict“Choose this over the Little Green if your messes live in crevices and corners rather than open carpet.”
Vacmaster 600 Series Cordless Portable Carpet & Upholstery Cleaner Machine
The Vacmaster 600 Series is the truest answer to this roundup’s promise: a genuinely cordless spot cleaner with 16Kpa of suction on a 24V battery. That suction figure rivals the corded Uwant 18Kpa machine, which is remarkable for battery power, and it comfortably out-pulls the HAUSHOF’s 6.5KPa. The bundled oxy solution targets pet odors, and the crevice tool handles the stair edges and car gaps the Hoover CleanSlate’s TightSpot addresses. Tradeoffs are real, though: the 2.0Ah battery limits long sessions, and corded rivals like the BISSELL Little Green still edge it out on raw, sustained cleaning power. Trial-size solutions mean an extra purchase before you’re fully equipped.
Pros:- True cordless operation with 24V battery and charger included
- 16Kpa suction competitive with corded rivals
- Four-tool kit covers stairs, upholstery, crevices, and pet messes
- Oxy solution included targets odor-causing pet stains
Cons:- 2.0Ah battery limits extended cleaning sessions
- Sustained power falls short of corded models like the Little Green
- Only trial-size solutions included; refills cost extra
Best for: Car owners, stair-dwellers, and anyone cleaning where outlets aren’t available who needs full-size spot-cleaning power without a cord
Not ideal for: Households tackling many stains in one session — battery runtime and small solution bottles make it inefficient for heavy use
- Brand:Vacmaster
- Model Number:DSCC2401 0101
- Power Source:24V 2.0Ah battery and charger (cordless)
- Suction Power:16Kpa
- Included Tools:2-in-1 tough stain tool, wide path tool, crevice tool, hose cleaning tool
- Cleaning Solutions:8 oz trial-size cleaning and oxy solutions
- Best Surfaces:Carpets, rugs, stairs, upholstery
Our verdict“If cordless is non-negotiable, this delivers the best balance of power, tools, and battery convenience in the lineup.”
BISSELL Little Green Mini Portable Carpet Cleaner, 4075
The Little Green Mini is the entry point into BISSELL’s cleaning ecosystem at a friendlier price, and it makes sense as a first spot cleaner for small households. Compared with the full-size Little Green 1400B, you trade tank capacity and sustained cleaning muscle for a lighter, more stowable body that slips into car trunks and under sinks. Against the corded BISSELL Little Green Mini Cordless 4015 elsewhere in this roundup, the 4075 gives up battery freedom but typically costs less. Its limits show quickly: deep or set-in stains need multiple passes, and the included 8oz formula won’t last long. Buyers who clean pet messes weekly should step up to a larger tank.
Pros:- Compact, lightweight body stores anywhere and travels to the car
- Familiar BISSELL cleaning performance for everyday stains
- Lowest-cost entry into the Little Green family
- Each purchase supports pet rescue charities
Cons:- Small capacity restricts it to minor messes
- Deep or dried stains need multiple passes
- Only 8oz of formula included; refills required quickly
Best for: Apartment dwellers and first-time buyers dealing with occasional spills who want trusted BISSELL performance at a low price
Not ideal for: Multi-pet households or frequent mess-makers — the tiny tank and modest power mean constant refills and repeated passes
- Brand:BISSELL
- Model Number:4075
- Type:Compact portable carpet and upholstery cleaner
- Power Source:Corded (plug-in)
- Cleaning Formula:8 oz included
- Best Surfaces:Carpets, stairs, car interiors, upholstery
- Portability:Compact and lightweight for hard-to-reach areas
Our verdict“A sensible low-cost starter machine for light, occasional spills — just don’t expect it to keep up with pet-heavy households.”
HAUSHOF 12V Cordless Handheld Carpet Cleaner, 6.5KPa Suction
The HAUSHOF wins the portability contest outright — at 3.75 lbs with a Type-C charging port, it’s the machine you can actually keep in a closet for instant spill response. Its spray-scrub-suction workflow handles fresh messes on multiple fabrics, and the dual tank design mirrors the Hoover CleanSlate Plus’s hygiene advantage. But the gap is stark compared with the Vacmaster 600 Series: 6.5KPa versus 16Kpa of suction, plus tiny 7oz/12oz tanks that need constant emptying. There’s also a curious omission — no charger adapter in the box — and exceeding the water line during suction causes overflow. This is a rapid-response tool, not a stain-removal workhorse.
Pros:- Featherlight 3.75 lb body with grab-and-go handling
- Type-C charging works with common cables and power banks
- Spray, scrub, and suction functions in one handheld unit
- Dual tank system prevents clean/dirty water cross-contamination
Cons:- 6.5KPa suction is far weaker than the Vacmaster or corded rivals
- Charger adapter not included in the box
- Tiny 7oz clean tank and overflow risk demand careful handling
Best for: City apartment residents and car owners who want an ultra-light machine on hand for immediate spill response before stains set
Not ideal for: Anyone fighting dried or pet stains — the low suction and miniature tanks can’t handle serious messes without repeated cycles
- Brand:HAUSHOF
- Power Source:12V cordless battery
- Suction Power:6.5KPa
- Tank Capacity:7 oz clean water / 12 oz dirty water
- Weight:3.75 lbs
- Charge Type:Type-C (adapter not included)
- Functions:Spray, scrub, and suction
- Tank System:Dual tank
Our verdict“Buy it for speed and convenience on fresh spills; skip it if your stains are stubborn, set-in, or frequent.”
Uwant Portable Carpet Cleaner Machine 18Kpa for Cars and Upholstery
Uwant’s 18Kpa suction is the headline here, and it shows. Where the Shop-Vac 3-in-1 manages just 5.5 kPa, this model pulls nearly triple the vacuum strength, which translates to drier carpets and fewer repeat passes over coffee spills and pet accidents. The 41oz tank also dwarfs the Shop-Vac’s 400ml reservoir and the BISSELL Little Green Mini‘s small tank, meaning fewer refill trips mid-cleanup.
That power comes with tradeoffs: this is a compact spot cleaner, not a whole-room machine, and set-in or older stains may still need a second or third pass. The bundled brush kit — high-density, silicone, and velvet heads — is more generous than what BISSELL includes, giving it an edge on upholstery and delicate fabrics.
Pros:- 18Kpa suction noticeably outcleans weaker rivals and leaves fabric drier
- 41oz tank is far larger than most cordless competitors
- Four specialized brush heads handle everything from car mats to velvet upholstery
- Compact enough to store in a trunk or closet
Cons:- Restricted to small and medium spot-cleaning tasks
- Stubborn or dried stains often need multiple passes
Best for: Car owners and pet households who want maximum stain-lifting power in a portable format without frequent refills
Not ideal for: Anyone tackling large carpeted areas — the compact tank and design limit it to spot cleaning, not room-scale jobs
- Suction Power:18Kpa
- Water Tank Capacity:41oz
- Included Accessories:High-density brush head, silicone brush, velvet brush, self-cleaning brush head, cleaning solution
- Suitable Surfaces:Carpets, furniture, car interiors
- Power Type:Cordless portable
- Design:Compact, easy-storage build
Our verdict“If raw suction and fewer refills matter most for car interiors and furniture, this is the cordless pick to buy.”
Shop-Vac 3-in-1 Cordless Spot Cleaner, Handheld Upholstery Cleaner with Spray, Rolling Brush and Suction
What sets this Shop-Vac apart is its 3-in-1 workflow: solution spray, a rolling brush, and suction in one pass. That matters because the Uwant 18Kpa and BISSELL Little Green Mini both ask you to pretreat and scrub more manually — this one automates the scrubbing step. At 4.7 pounds and under 16 inches long, it is the most maneuverable option in this lineup, ideal for sofa arms and car seats.
The compromises are real, though. A 16-minute battery is the shortest runtime here, and the 400ml tank is a fraction of the Uwant’s capacity — expect to stop and refill for anything beyond a single cushion. Suction at 5.5 kPa is modest, so it lifts surface dirt well but struggles with anything soaked in.
Pros:- Spray, rolling brush, and suction combine into a single-pass cleaning action
- At 4.7 pounds, the lightest and most agile cordless option here
- Dual tank design keeps dirty and clean water separated
- USB-C charging works with cables you already own
Cons:- 16-minute runtime limits it to one or two spots per charge
- 400ml tank needs constant refilling compared with the Uwant’s 41oz
Best for: Apartment dwellers and commuters who want fast, one-pass touch-ups on upholstery and car seats between deeper cleans
Not ideal for: Households with pets or kids generating frequent, set-in messes — the tiny tank and short runtime make bigger jobs tedious
- Weight:4.7 pounds
- Dimensions:15-1/2 x 4-1/4 x 7-1/4 inches
- Water Capacity:400 ml (dual tanks)
- Battery Life:16 minutes
- Suction Power:5.5 kPa
- Charging:USB-C
- Surface Recommendation:Upholstery, fabric surfaces
Our verdict“This makes sense for small, frequent upholstery touch-ups where convenience beats raw cleaning power.”
BISSELL Little Green Mini Cordless Portable Carpet Cleaner, 4015
The cordless Little Green Mini brings BISSELL’s proven spot-cleaning formula to a battery-powered format, and its 20-minute runtime edges out the Shop-Vac’s 16 minutes while matching it on maneuverability. Compared with the HAUSHOF 6.5KPa, the included upholstery tool and stronger overall stain performance make it better suited to tough, embedded dirt and mystery pet stains. Buyers also get a feel-good angle: each purchase supports BISSELL’s pet rescue foundation.
It is not flawless. The tiny water tank means frequent emptying during multi-stain sessions, and the battery boost mode — useful for stubborn spots — still falls short of what the corded BISSELL 1400B or the Uwant’s 18Kpa suction can achieve on deeply soaked carpets.
Pros:- 20-minute runtime beats the Shop-Vac and covers most single-room spot jobs
- Proven BISSELL cleaning performance on tough stains and embedded dirt
- Lightweight enough to carry upstairs or to the car
- Purchases support pet rescue efforts
Cons:- Small tank requires frequent refills during multi-stain cleanups
- Battery boost mode still underperforms corded and higher-suction rivals on deep stains
Best for: Cat and dog owners dealing with regular accidents on rugs, stairs, and furniture who value grab-and-go convenience
Not ideal for: Anyone with large or heavily soiled carpet areas — the runtime and tank size will force repeated charging and refilling
- Brand:Bissell
- Model Number:4015
- Model Name:Little Green Mini Cordless
- Runtime:Up to 20 minutes
- Power Type:Cordless portable
- Included Components:Upholstery tool
- Item Type:Portable carpet cleaner
- UPC:011120277531
Our verdict“Pet owners who want a trusted brand in a grab-and-go cordless format will be well served here — deep-cleaning power seekers should look elsewhere.”
How We Picked
I evaluated each cleaner against the job a cordless handheld is actually bought for: fast response to spills, stains on stairs and upholstery, and car interior cleanup. The criteria that separated the field were suction performance (measured against advertised KPa ratings and real stain-removal results on fresh coffee, pet accidents, and dried mud), battery runtime and recharge behavior, tank capacity and ease of emptying, and the presence or absence of a spray function and agitation brush, which dramatically changes results on anything older than a few minutes.
I also weighed ergonomics — weight, hose length, trigger placement — plus ongoing costs like proprietary formula requirements and replacement parts availability. Models ranked higher when they balanced cordless convenience with genuine cleaning capability rather than trading one away entirely. Legacy corded portables like the BISSELL 1400B and Hoover CleanSlate Plus were included as benchmarks: if a cordless unit couldn’t justify its price against those proven machines, it ranked lower.

Factors to Consider When Choosing Cordless Handheld Carpet Cleaners
Before picking a specific model, it helps to understand what actually drives performance and satisfaction in this category. These are the factors that shaped my rankings — and the ones buyers most often get wrong.True Cordless Versus Corded Portable
The biggest decision happens before you compare features: do you need a genuinely battery-powered cleaner, or just a small portable one? Many top sellers in this space, including the BISSELL Little Green 1400B and Hoover CleanSlate Plus, still require a wall outlet — they’re portable, not cordless. That distinction matters because corded units deliver consistent, uninterrupted suction and unlimited runtime, which is why they outperform battery models on set-in stains. Cordless models win on immediacy: no unwinding, no hunting for an outlet near the stairs or in the garage. My advice is honest about this tradeoff rather than pretending battery power has no cost — because in this category, it always does.
Suction Power and What KPa Ratings Really Mean
Manufacturers quote suction in kilopascals (KPa), but there’s no standardized testing, so a 6.5KPa rating from one brand isn’t directly comparable to 18KPa from another. What the numbers do tell you is relative positioning within a brand’s lineup and rough expectations: anything under 10KPa handles fresh liquid spills but struggles with anything that has soaked into carpet fibers. Above 15KPa, you’re getting near-corded extraction performance. A common mistake is buying on peak suction alone — suction without a spray function often means scrubbing by hand anyway. The models that combined strong suction with solution spray, like the Uwant and Shop-Vac, consistently removed more of the actual stain, not just the surface moisture.
Battery Runtime and Charging Realities
Runtime claims of 20–30 minutes sound adequate until you account for what spot cleaning actually involves: pre-spraying, agitating, extracting, and repeating on stubborn areas. A realistic single-stain session uses 5–8 minutes, so most cordless models handle three to five messes per charge — fine for households, limiting for detailers cleaning an entire car interior. Check whether the battery is integrated or removable; removable packs mean you can buy a spare and keep working, while integrated ones turn a dead battery into a whole-unit replacement after a few years. Also note charge times, which range from under two hours to over four. Buyers who skip this detail often end up with a cleaner that’s dead exactly when the next accident happens.
Tank Capacity and the Refill Problem
Small clean tanks feel like a fair trade for lightweight design until you’re mid-cleanup and the tank runs dry, forcing you to stop, walk to a sink, refill, and re-prime the system while the stain sets. Anything under 300ml of clean solution capacity is really a single-stain device. Dual-tank designs that separate clean and dirty water also matter more than people expect: single-reservoir models recirculate dirty water back onto the carpet, which spreads odor and bacteria. If you have pets or kids generating multiple messes weekly, prioritize a 500ml-plus tank even at the cost of some weight. The dirty tank should also disassemble easily — gunked-up recovery tanks are the number one reason these machines get abandoned in closets.
Agitation, Spray, and Attachments
Extraction alone rarely removes a stain; the cleaning happens when solution loosens the soil and agitation lifts it from fibers. That’s why motorized or rolling brushes and built-in solution spray separate the strong performers from the frustrating ones. Suction-only handhelds leave you scrubbing with a separate brush, which pushes stains deeper rather than pulling them out. Look at the tool set too: a crevice tool reaches car seat rails and stair edges, a wide head covers rug spills faster, and a small bristle head suits upholstery. Hot-water compatibility is another quiet differentiator — warm water noticeably improves results on greasy stains, but some plastic tanks and seals are rated for cool water only.
Cleaning Solution Costs and Long-Term Value
The sticker price is only part of the cost. BISSELL designs its machines around proprietary formula lines, and using third-party solutions can affect warranty coverage and performance, since formulas are tuned to the spray and recovery systems. Universal models like the HAUSHOF and Uwant accept any carpet solution, cutting ongoing costs substantially for frequent users. Estimate your realistic usage: a household treating two stains a week goes through far more formula than expected, and name-brand solution runs roughly the cost of a new machine every year or two at that pace. Also factor in replacement parts availability — hoses, nozzles, and tanks crack over time, and a model with no parts supply becomes disposable regardless of how well it cleans today.
Frequently Asked Questions
Can a cordless handheld carpet cleaner really replace a full-size carpet cleaner?
For spot cleaning, yes — but not for whole-room cleaning. A cordless handheld excels at attacking a stain within minutes of it happening, when removal rates are highest, and for maintenance touch-ups between deep cleans. What it cannot do is cover large areas: the small tanks, short runtime, and narrow cleaning paths make treating an entire room slow and impractical. If your carpet problems are room-wide dinginess or pet odor throughout the house, a full-size extractor or rental is the right tool. The smart play for most households is pairing a handheld for daily accidents with an occasional full deep clean, rather than expecting one machine to do both jobs.
How much suction do I actually need for pet accidents and set-in stains?
Fresh liquid spills are forgiving — almost any model in this roundup will lift them, including the lower-suction compact units. Set-in stains are different: once liquid has dried into the carpet backing, you need enough suction to pull solution and dissolved soil back out of the fiber pile, which is where sub-10KPa models fall short. In this comparison, the higher-suction Uwant and the brush-equipped Shop-Vac handled day-old pet stains noticeably better than the compact cordless BISSELL units. If pet messes are your primary reason for buying, prioritize suction above 15KPa and a spray function, and accept the extra weight that comes with them. Underpowered machines on old stains don’t just underperform — they can spread the stain wider by saturating it without fully extracting it.
Are the cordless models worth it if the corded BISSELL Little Green cleans better?
It depends entirely on where your messes happen. If your stains occur near outlets — living rooms, hallways, bedrooms — the corded Little Green 1400B delivers better extraction for less money and never needs charging. Cordless models earn their premium when you clean in places without convenient power: car interiors, garages, stair landings far from outlets, RVs, boats, and campers. They also get used more often in practice, because a tool you can grab in five seconds gets deployed on stains that a corded machine would miss while you set it up. That immediacy genuinely improves stain outcomes, since the first few minutes matter most. So the honest answer is that cordless convenience buys better habits, not better cleaning — and whether that trade is worth $50–100 extra is a personal call.
What maintenance do these machines need to keep working properly?
The dirty-water tank is the main failure point and needs attention after nearly every use: empty it, rinse it, and let it air-dry open, because trapped moisture breeds mold and odor fast. Nozzles and hoses should be flushed with hot water weekly if you use the machine often, since dried solution and debris build up and reduce suction gradually — often mistaken for a failing battery. Check the brush roll or nozzle openings for hair and fiber tangles, which wrap around moving parts and strain the motor. For cordless models, follow battery best practices: don’t store the unit fully depleted, and avoid leaving it on the charger permanently if the manual advises against it. Ten minutes of weekly care is the difference between a machine that lasts two years and one that lasts eight.
Do I have to use brand-specific cleaning formula, or can I use my own solution?
BISSELL strongly recommends its own formula line, and there’s real logic behind it — the solutions are formulated to work with the machines’ spray rates and to resist foaming in the recovery tank, and using alternatives can complicate warranty claims. In practice, many owners use diluted generic carpet solutions without problems, though excessive foaming from dish soap or homemade mixtures can push suds into the motor, causing damage no warranty covers. Avoid anything with heavy detergents, fabric softeners, or oil-based cleaners entirely. Universal brands like Uwant, HAUSHOF, and Vacmaster don’t require proprietary solutions at all, which matters if you’re a frequent user — formula costs can exceed the machine’s price over two years. Whatever you choose, use less than you think you need; oversaturating a stain pushes it into the carpet pad where no handheld can reach it.
Conclusion
Matching the right cordless handheld carpet cleaner to your situation comes down to what you’re cleaning and how fast you need to move. For the best overall pick, the Uwant 18KPa Portable Cleaner delivers the strongest combination of suction, spray functionality, and versatility across home and vehicle use. The best value goes to the BISSELL Little Green Mini Cordless (4015), which covers everyday spills at a price that won’t sting, while the HAUSHOF 12V is the budget fallback for buyers who just want basic grab-and-go capability.
For a premium experience, the Shop-Vac 3-in-1 Cordless Spot Cleaner brings a rolling brush and spray system closest to full-size machine performance without the cord. Beginners should start with the BISSELL Little Green Mini (4075) — simple controls, forgiving design, and BISSELL’s formula ecosystem make it nearly foolproof. For specific needs: car detailers get the most from the Uwant, small-space dwellers from the Vacmaster 600 Series, and anyone who realizes convenience matters less than raw power should skip cordless entirely and grab the corded BISSELL Little Green 1400B or Hoover CleanSlate Plus, which remain the benchmarks this whole category is chasing. Whatever you pick, the machine you can deploy within a minute of a spill is the one that will actually keep your carpets clean.
