BISSELL Little Green Pet Deluxe Portable Carpet Cleaner
The BISSELL Little Green Pet Deluxe is the most practical choice here for households that regularly deal with pet accidents, muddy paw prints, food spills, and stained upholstery. Its 48-ounce clean-water tank and 45-ounce dirty-water tank let you work longer between refills than the smaller cordless model.
The accessory set is especially useful for pet cleanup. The 3-inch Tough Stain Tool scrubs and extracts spots, the Stain Trapper Tool keeps wet messes inside the removable tool cup, and the HydroRinse tool helps flush residue from the hose after cleaning. It also includes trial-size pet formulas.

BISSELL Little Green Mini Cordless Deep Cleaner

The 16-ounce clean tank and 13.5-ounce dirty tank keep the machine compact, but they also make it better for quick jobs than repeated large messes. Standard mode provides up to 15 minutes of runtime, while BatteryBoost+ mode can extend runtime to up to 20 minutes under the manufacturer’s stated use conditions. A full charge takes about four hours.

BISSELL Little Green Max Pet SmartMix Deep Cleaner
The BISSELL Little Green Max Pet SmartMix is a compact corded option for buyers who want more cleaning power without moving up to a full-size machine. Its SmartMix system automatically combines water and formula, so you do not have to measure the cleaning solution for each job. You can also choose a rinse setting when you want to use water without formula.
Both the clean-water and dirty-water tanks hold 32 ounces. The machine weighs 8.2 pounds and includes a Self-Cleaning Tough Stain Tool for flushing residue after use, plus a pet hair removal tool for lifting fur from compatible soft surfaces. BISSELL markets this model with a 30% suction comparison based on a specified laboratory air-power test against named competing portable cleaners, so that figure should not be treated as a universal claim against every competitor.

- Dirty tank: 32 oz.
- Weight: 8.2 lb.
- Formula system: SmartMix automatic water-and-formula mixing

Cons:
- Corded operation is less convenient in cars or areas without an outlet.

Factors to Consider When Choosing a BISSELL Little Green Cleaner for Pet Stains
The best model depends on how often you clean, where the messes happen, and whether you prefer continuous power or cordless convenience. Compare the following points before buying.
Cleaning Performance and Intended Use
Portable carpet cleaners are designed for spot cleaning, stairs, upholstery, pet beds, vehicle interiors, and other small areas. They spray cleaning solution, agitate the stain with a tool, and extract dirty liquid. For an entire carpeted room, a full-size upright carpet cleaner is usually more efficient because it has wider cleaning paths and larger tanks.
Suction matters, but tool design, stain pretreatment, the correct formula, and repeated dry extraction passes also affect the result. Avoid assuming that any portable cleaner will remove every old, dyed, bleached, or permanently set stain.
Portability and Weight
The 7-pound Mini Cordless is the easiest model to carry between rooms or into a vehicle. The Max Pet SmartMix weighs 8.2 pounds, while the Pet Deluxe weighs 9.7 pounds. A lighter machine is easier to transport, but larger tanks usually reduce the number of refill stops.
Tank Capacity
The Pet Deluxe has the largest clean tank at 48 ounces, making it the better choice for several stains in one session. The Max Pet SmartMix uses 32-ounce clean and dirty tanks for a balance of capacity and compact size. The Mini Cordless has a 16-ounce clean tank and is better suited to quick spills.
Empty the dirty tank after each session rather than storing recovered water in the machine. Rinse removable tanks and tools according to the manufacturer’s instructions to reduce residue and odors.
Included Tools and Accessories
Choose tools based on the messes you face. A standard stain tool is useful for scrubbing upholstery and carpet spots. A Stain Trapper Tool helps isolate liquid messes. A pet hair tool can lift loose or embedded fur before or during cleaning. A HydroRinse or self-cleaning tool helps flush residue from the hose or tool path after use.
Accessory bundles can vary by model or retailer, so review the exact “included components” list before ordering.
Corded vs. Cordless
Corded models provide continuous power and are better for several stains, repeated pet accidents, or longer upholstery jobs. Cordless models are easier to move around cars, stairs, patios, and rooms without a convenient outlet, but battery runtime limits the size of each session.
Pet-Specific Features
Pet-focused tools can make cleanup more manageable, but cleaning formula and technique still matter. Blot fresh liquid first, remove solid debris, pretreat when the surface and formula instructions allow it, and make slow extraction passes. Do not oversaturate cushions, carpet backing, foam, or vehicle seats.
Surface Compatibility and Safety
Use only a formula labeled for portable carpet cleaners and compatible with the machine. Fill with warm tap water when directed, not boiling water. Keep the cleaner and wet cords away from standing water, and allow the surface to dry fully before regular use.
Battery Life and Charge Time
The Mini Cordless can run for up to 15 minutes in Standard mode or up to 20 minutes in BatteryBoost+ mode under BISSELL’s stated testing assumptions. Its charge time is about four hours. Think about whether you usually clean one fresh spill or several areas at once before choosing cordless convenience.
Warranty and Replacement Parts
Warranty length and included accessories vary by model. Keep your receipt and model number, register the machine if desired, and consult BISSELL’s support portal for the correct manual, replacement tank, cap, hose tool, or formula. Verify that a part is listed for your exact model before ordering.
Before You Buy: Quick Checklist
- Choose the Pet Deluxe for the largest tank and liquid-mess tool.
- Choose the Mini Cordless for cars, stairs, quick spills, and easy storage.
- Choose the Max Pet SmartMix for automatic formula mixing and stronger corded suction.
- Confirm the exact tools included with the retailer’s bundle.

- Buy a full-size carpet cleaner instead if your main goal is washing entire rooms.
Frequently Asked Questions
How Often Should I Use a Portable Carpet Cleaner?
Use it when a spot or spill needs wet extraction rather than following a fixed schedule. Clean fresh pet accidents promptly after removing solids and blotting excess liquid. For full-room maintenance, follow the carpet manufacturer’s care guidance and use equipment designed for larger areas.
Can a BISSELL Little Green Clean Upholstery and Car Interiors?
Yes, these models are intended for many carpet, upholstery, stair, pet-bed, and vehicle-interior spot-cleaning jobs. Check the material’s care label first, use the correct formula, test a hidden area, and avoid oversaturating foam-backed seats or cushions.
What Types of Messes Can a Little Green Cleaner Handle?
These machines are designed for common spots and spills such as tracked-in dirt, muddy paw prints, food spills, and many fresh pet accidents. Results depend on the material, stain age, previous treatments, formula, and cleaning technique. No portable cleaner can guarantee removal of every permanent or color-damaging stain.
How Long Does Carpet or Upholstery Take to Dry?
Drying time varies with the amount of solution used, extraction passes, fabric thickness, room temperature, humidity, and airflow. Make extra suction-only passes, improve ventilation, and keep people and pets off the area until it is fully dry.
Can I Use Any Cleaning Solution in These Machines?
No. Use only a BISSELL formula labeled for portable carpet cleaners and compatible with the machine. Unapproved detergents, excessive foam, bleach, boiling water, or homemade mixtures may damage components, leave residue, or affect warranty coverage.
Are Replacement Parts Available?
BISSELL provides model-specific support and lists replacement items for many Little Green machines. Availability can vary, so search by the exact model number printed on the cleaner before purchasing a tank, cap, tool, hose part, or charger.
Final Recommendation
Choose the BISSELL Little Green Pet Deluxe if you regularly clean pet accidents and want the largest tank plus a Stain Trapper Tool. Choose the Little Green Mini Cordless if portability, car cleaning, and fast spot treatment matter most. Choose the Little Green Max Pet SmartMix if you want automatic formula mixing, useful pet tools, and stronger corded suction in a compact machine.
All three are suitable for targeted pet-stain cleanup, but the right choice depends on whether you prioritize capacity, cordless mobility, or cleaning convenience.
