If you need a portable carpet cleaner for spills, pet accidents, upholstery, carpeted stairs, area rugs, or vehicle interiors, these Hoover and BISSELL spot cleaners cover several different priorities. The right choice depends on the size of the mess, available storage space, tank capacity, included tools, and how much cleanup you want to do after each use. These are corded spot-cleaning machines for targeted messes, not efficient substitutes for a full-size cleaner on wall-to-wall carpet.
Quick verdict
The Hoover CleanSlate Plus is the most versatile all-around option here because its wide and narrow tools handle both broad spills and tight spaces. Choose the BISSELL Little Green Max Pet SmartMix for automatic formula mixing, the Little Green Mini for the smallest storage footprint, the Pet Deluxe for isolating liquid pet messes, or the 1400B for a straightforward design with a 48-ounce clean-water tank and three included cleaning tools.
How these picks were compared: The recommendations below are based on current published specifications, included tools, clean- and dirty-tank capacity where listed, portability, reach, maintenance features, and intended use.

Hoover CleanSlate Plus Portable Carpet Spot Cleaner

The Hoover CleanSlate Plus is a practical choice for households that regularly deal with spills on carpet, stairs, furniture, or vehicle upholstery. Its main advantage is the combination of a 7-inch WidePath Tool for broader stains and a TightSpot Tool for crevices, couch edges, and narrow stair areas.
The cleaner weighs approximately 9.4 pounds and has a 40-ounce clean-solution tank. Its separate clean- and dirty-water tanks prevent extracted water from mixing with fresh solution. A hose-rinse attachment also helps flush residue from the hose after use.
Why You’ll Like It: It gives you more tool flexibility than cleaners supplied with only one standard stain brush. The wide tool can reduce the number of passes needed on larger spills, while the narrow attachment provides better access around furniture and car seats.
Best For: Families, pet owners, and vehicle owners who want one portable machine for both wide stains and tight spaces.
Who Should Avoid It: Buyers who need to deep-clean entire rooms or who want a cordless machine.
Pros:
- Includes separate tools for broad stains and narrow crevices.
- Dual-tank design keeps clean solution separate from extracted water.
- Hose-rinse tool simplifies post-cleaning maintenance.
- Suitable for carpet, stairs, compatible upholstery, and vehicle interiors.
Cons:
- Corded operation requires a nearby electrical outlet.
- The 40-ounce tank is smaller than the 48-ounce tanks on two BISSELL models in this roundup.
- It is intended for spot cleaning rather than full-room carpet extraction.
BISSELL Little Green Max Pet SmartMix Cleaner (38572)

The BISSELL Little Green Max Pet SmartMix 38572 is designed for homes that frequently clean muddy paw prints, food spills, pet beds, carpeted stairs, upholstery, and car interiors. Its SmartMix Technology automatically combines water and cleaning formula, reducing the need to measure solution manually.
This corded machine weighs approximately 8.2 pounds and uses separate 32-ounce clean- and dirty-water tanks. BISSELL advertises 30% more powerful suction than two named compact cleaners under its stated ASTM F558 hose air-power test. Treat that as a limited manufacturer comparison, not independent proof that it will outperform every portable cleaner.
The included self-cleaning Tough Stain Tool can flush residue from the tool after a mess has been extracted, which is particularly useful when dealing with unpleasant pet accidents.
Why You’ll Like It: Automatic formula mixing removes a common setup step, and the water-only rinse setting provides more control when you do not need additional cleaning formula.
Best For: Pet owners who want automatic solution mixing and a tool designed to rinse away residue after cleaning.
Who Should Avoid It: Buyers who prefer a larger clean-water tank or need to clean broad carpeted areas in one session.
Pros:
- SmartMix system automatically combines formula and water.
- Self-cleaning stain tool is useful for messy pet accidents.
- Lighter than the full-size Little Green Pet Deluxe and 1400B models.
- Suitable for carpet, rugs, pet beds, upholstery, and vehicle interiors.
Cons:
- The 32-ounce tanks may need more frequent refilling and emptying than 48-ounce models.
- Corded design limits use away from electrical outlets.
- The manufacturer’s 30% suction comparison applies only to specifically named competing models and test conditions.
BISSELL Little Green Mini Portable Carpet Cleaner

The BISSELL Little Green Mini 4075 is the most compact cleaner in this roundup. It weighs approximately 7 pounds and has a 16-ounce clean-water tank plus a 13.5-ounce dirty-water tank, making it easier to carry, store in a cabinet, or keep available for isolated spills.
It uses a 4-inch Tough Stain Tool to spray, scrub, and extract moisture from carpet, compatible upholstery, pet beds, and vehicle interiors. The linked 4075 package also includes a HydroRinse self-cleaning hose tool and an 8-ounce trial bottle of BISSELL Little Green formula. Its 12-foot cord and 4-foot hose provide reasonable reach for small jobs, though less reach than some larger models.
Why You’ll Like It: Its small footprint is useful in apartments, dorms, RVs, and homes without room for a larger cleaning appliance.
Best For: Occasional spills, small upholstery jobs, car detailing, and buyers with limited storage.
Who Should Avoid It: Anyone planning to clean several rooms, a large sectional, or multiple heavily soiled areas in one session.
Pros:
- Lightest and most compact machine in this comparison.
- Fits more easily in small cabinets and closets.
- Includes a 4-inch stain tool and hose-rinsing attachment.
- Suitable for quick carpet, upholstery, and vehicle spot cleaning.
Cons:
- The 16-ounce clean tank requires more frequent refilling during larger jobs.
- Its smaller dirty-water tank fills sooner than those on the other models.
- Corded operation still requires access to an outlet.
BISSELL Little Green Pet Deluxe Portable Carpet Cleaner

The BISSELL Little Green Pet Deluxe 3353 combines the standard Little Green design with tools aimed at difficult pet messes. Its most useful accessory is the Stain Trapper Tool, which collects extracted liquid inside the attachment instead of immediately drawing the mess through the main hose.
The cleaner has a 48-ounce clean-water tank, a 45-ounce dirty-water tank, a 4.5-foot hose, and an approximate weight of 9.7 pounds. It also includes a 3-inch Tough Stain Tool, HydroRinse self-cleaning hose tool, and trial-size pet-cleaning formulas. BISSELL currently lists a one-year limited warranty for this model.
Why You’ll Like It: The Stain Trapper attachment is a meaningful advantage for urine, vomit, and other liquid accidents that you may not want traveling through the entire hose.
Best For: Pet owners who regularly handle liquid accidents and want a larger tank than the Max Pet SmartMix or Mini models.
Who Should Avoid It: Buyers who do not need pet-specific accessories or who want the lightest possible machine.
Pros:
- Stain Trapper tool isolates unpleasant liquid messes.
- 48-ounce clean tank supports longer spot-cleaning sessions.
- HydroRinse tool helps flush residue from the hose.
- Includes pet-focused formula and multiple cleaning attachments.
Cons:
- Heavier and bulkier than the Little Green Mini.
- Pet-focused accessories may be unnecessary for homes without animals.
- Still intended for spot treatment rather than efficient full-room cleaning.
BISSELL Little Green Portable Carpet Cleaner (1400B)

The BISSELL Little Green 1400B is a general-purpose portable carpet and upholstery cleaner for spills, muddy footprints, pet messes, stairs, area rugs, and vehicle interiors. It uses a straightforward spray, scrub, and suction process without the automatic mixing system found on the Max Pet SmartMix.
Its 48-ounce clean-water tank is tied for the largest in this roundup. The current manufacturer-listed package includes a 3-inch Tough Stain Tool, a Spraying Crevice Tool, and a HydroRinse self-cleaning hose attachment. The machine weighs approximately 9.65 pounds and has a 15-foot power cord.
Why You’ll Like It: It provides a larger tank and a useful three-tool package without requiring a pet-specific design or automatic solution-mixing system.
Best For: Buyers seeking a familiar, versatile spot cleaner for everyday carpet, upholstery, stair, and vehicle messes.
Who Should Avoid It: Buyers prioritizing minimum weight, very compact storage, or tools designed specifically to isolate liquid pet waste.
Pros:
- Large 48-ounce clean-water tank.
- Includes stain, crevice, and hose-rinsing tools.
- Useful for a broad range of household and vehicle surfaces.
- Simple spray, scrub, and extraction operation.
Cons:
- Heavier and less compact than the Little Green Mini.
- Does not automatically mix cleaning formula and water.
- Its standard stain tool is narrower than Hoover’s 7-inch WidePath tool.
Factors to Consider When Choosing a Portable Carpet Cleaner

The best portable carpet cleaner for your home depends on the size and frequency of your messes, the surfaces you plan to clean, available storage space, and how much maintenance you are willing to perform after each use.
Portable Spot Cleaner vs. Full-Size Carpet Cleaner
Portable machines are designed primarily for localized spills, stairs, upholstery, pet beds, rugs, and vehicle interiors. Their smaller tanks and handheld tools make them convenient for fast cleanup but inefficient for cleaning entire carpeted rooms.
Choose a full-size upright carpet cleaner or professional cleaning service when you need to deep-clean wall-to-wall carpeting. Choose a portable spot cleaner when fast setup, targeted extraction, and easy storage matter more than floor coverage.
Suction and Extraction Performance
Effective extraction matters because leaving too much moisture in carpet or upholstery can increase drying time. However, suction claims are difficult to compare unless manufacturers use the same test method. Avoid treating broad percentage claims as universal proof that one machine will outperform every competitor.
Technique also affects results. Make slow extraction passes without holding the spray trigger, and repeat dry passes until the tool removes very little additional moisture.
Tank Capacity Considerations
A larger clean-water tank reduces interruptions during extended cleaning. The BISSELL Pet Deluxe and 1400B provide 48-ounce clean tanks, while the Hoover CleanSlate Plus provides 40 ounces. The Max Pet SmartMix has a 32-ounce tank, and the Little Green Mini has a 16-ounce tank.
Larger tanks add size and operating weight, so the biggest tank is not automatically the best choice. A small tank may be more convenient when you usually clean one chair cushion, one vehicle seat, or a single pet accident.
Included Tools and Cleaning Path
Look beyond the number of accessories and consider what each tool actually solves. A wide tool is helpful for broad spills and carpeted stairs. A crevice tool reaches along cushions, baseboards, and vehicle seats. Pet tools may isolate extracted liquid, while hose-rinse attachments make cleanup easier.
The Hoover CleanSlate Plus has the widest standard tool in this comparison. The BISSELL Pet Deluxe offers the most specialized attachment for liquid pet accidents.
Portability, Storage, and Reach
Check the machine’s weight, footprint, power-cord length, hose length, handle position, and onboard tool storage. The 7-pound Little Green Mini is the easiest model here to store in a small cabinet, but its 16-ounce clean tank and 13.5-ounce dirty tank require more frequent attention.
A longer combined cord and hose reach can reduce how often you move the main unit, especially while cleaning stairs, sofas, and vehicle interiors.
Cleaning Formula Compatibility
Use a formula approved for portable extraction machines and follow the cleaner manufacturer’s mixing instructions. Using too much formula can leave sticky residue that attracts fresh dirt. Do not substitute dish soap, laundry detergent, or a high-foaming household cleaner, since excess foam can interfere with extraction and may damage the machine.
Maintenance and Hose Cleaning
Empty and rinse both tanks after each session. Use the supplied hose-rinse or self-cleaning tool when available, remove hair from the brush and nozzle, and let washable parts air-dry before reassembly. Storing dirty water inside the machine can cause odors and residue buildup.
Warranty and Bundle Contents
Warranty length and included accessories can differ by model, region, color, or retailer bundle. Compare the model number and carton contents on the listing—not only the product-family name—before buying. This matters most when you want a specific crevice, pet, or hose-rinse tool.
Before You Use a Portable Carpet Cleaner
- Vacuum loose dirt, crumbs, and pet hair before wet cleaning.
- Check the furniture label for a W or WS upholstery cleaning code.
- Do not wet-clean fabric marked S or X.
- Test the solution on a hidden area before treating a visible surface.
- Use warm tap water only when permitted by the manufacturer. Do not use boiling water.
- Avoid oversaturating carpet backing, cushions, or upholstered furniture.
- Do not use a carpet extractor on hard flooring unless the manufacturer specifically approves that surface.
- Plug corded cleaners into a properly grounded outlet and keep the plug and electrical connections away from collected water.
- Do not assume a portable extractor sanitizes or disinfects a surface unless the machine, formula, and surface directions specifically support that claim.
Frequently Asked Questions
How Often Should I Use a Portable Carpet Cleaner?
Use a portable cleaner as soon as practical after a spill or pet accident, provided the surface is approved for water-based extraction. It is not necessary to wet-clean the same area on a fixed schedule if it is not dirty. For full-room maintenance, follow the carpet manufacturer’s care guidance and consider a full-size machine or professional service.
Can I Use These Cleaners on Upholstery?
Yes, but only on upholstery approved for water-based cleaning. Look for a W or WS code and test a hidden area first. Do not use a wet extractor on S-only or X-coded fabric. Avoid oversaturating cushions, seams, and padding.
Which Model Has the Largest Clean-Water Tank?
The BISSELL Little Green Pet Deluxe and BISSELL Little Green 1400B each have a 48-ounce clean-water tank. The Hoover CleanSlate Plus has a 40-ounce tank, the Max Pet SmartMix has a 32-ounce tank, and the Little Green Mini has a 16-ounce tank.
Which Portable Carpet Cleaner Is Best for Pet Accidents?
The BISSELL Little Green Pet Deluxe is the most specialized option for liquid pet accidents because its Stain Trapper Tool holds collected liquid inside the attachment. The Max Pet SmartMix is a strong alternative for frequent pet stains when automatic formula mixing and a self-cleaning stain tool are more important.
Can a Portable Carpet Cleaner Clean an Entire Room?
It may be technically possible, but it is usually slow and inefficient. Portable machines have narrow tools and relatively small tanks. A full-size upright carpet cleaner is better suited to wall-to-wall carpet and large open areas.
Do I Have to Use the Manufacturer’s Cleaning Formula?
Follow the instructions supplied with your machine and use a low-foaming formula labeled for portable carpet extractors. Manufacturer-approved formulas reduce compatibility risk. Never use dishwashing liquid, laundry detergent, or another high-foaming household cleaner in the tank.
Do Included Tools Vary Between Listings?
They can. Manufacturers and retailers may sell different bundles under similar product-family names. Confirm the exact model number, color, tool list, formula size, and warranty shown on the listing before ordering.
Do Portable Carpet Cleaners Sanitize Surfaces?
Not automatically. These machines spray solution and extract soil and moisture, but a cleaning claim is not the same as a sanitizing or disinfecting claim. Follow the directions for the specific machine, formula, and surface, and do not make a sanitation assumption that the label does not support.
How Long Do Carpet and Upholstery Take to Dry?
Drying time can range from a few hours to much longer depending on how much solution was applied, the material, room humidity, airflow, and the number of dry extraction passes. Improve airflow with fans, ventilation, or air conditioning, and keep people and pets off the damp area until it is fully dry.
How Do I Prevent Odors in the Machine?
Empty dirty water immediately after use, rinse both tanks, flush the hose, remove hair and debris from the nozzle, and allow parts to dry before storage. Do not leave cleaning solution or extracted water sitting inside the unit.
Conclusion
These five portable carpet cleaners address different priorities rather than offering identical performance. The Hoover CleanSlate Plus is the most versatile all-around option for buyers who value both a wide cleaning path and access to narrow spaces. The BISSELL Little Green Max Pet SmartMix is better suited to buyers who want automatic formula mixing and rinse mode, while the Little Green Mini is the easiest to carry and store.
Choose the Little Green Pet Deluxe when the Stain Trapper Tool and pet-focused accessories solve a specific problem in your home. Choose the Little Green 1400B when you prefer a straightforward general-purpose machine with a 48-ounce clean tank and a useful three-tool package.
Final recommendation
For most households, start with the Hoover CleanSlate Plus because its WidePath and TightSpot tools cover the broadest range of everyday cleaning situations. Pet owners should compare it directly with the BISSELL Max Pet SmartMix and Pet Deluxe based on whether automatic mixing or the Stain Trapper attachment would be more useful.
