BISSELL Little Green Max Pet SmartMix Portable Deep Cleaner
The BISSELL Little Green Max Pet SmartMix is the strongest all-around option in this group for pet owners who want a simpler setup. Its SmartMix Technology automatically combines water and cleaning formula, so you do not need to measure the ratio for each job. You can also switch to a water-only rinse mode when you want to make an extra extraction pass.
At 8.2 pounds, it remains portable while providing a 32 oz. clean tank and 32 oz. dirty tank. The self-cleaning Tough Stain Tool helps flush residue from the tool after use, while the separate tanks keep fresh solution away from recovered dirty water. BISSELL also states that this model delivers 30% more suction than specified competing compact spot cleaners under its stated test method; treat that as a manufacturer comparison rather than a universal claim against every portable cleaner.
Best For: Pet owners who want the easiest formula setup, a rinse option, and a balanced mix of portability and tank capacity.
Why You’ll Like It: SmartMix reduces measuring mistakes, and the rinse mode makes it easier to perform a final water-only pass on suitable surfaces.
Who Should Avoid It: Buyers who want the largest tank in this comparison or need a cordless cleaner.

BISSELL Little Green Pet Deluxe Portable Carpet Cleaner
The BISSELL Little Green Pet Deluxe is the better choice when you expect to clean several spots, a set of stairs, or multiple vehicle seats in one session. Its 48 oz. clean-water tank and 45 oz. dirty-water tank are the largest in this comparison, reducing how often you need to stop and refill.
It weighs 9.7 pounds and includes pet-focused accessories such as a 3-inch Tough Stain Tool, a Stain Trapper Tool, and a HydroRinse self-cleaning hose tool. The Stain Trapper Tool is especially useful for keeping unpleasant liquid messes contained in the tool instead of pulling them directly through the main hose.
Best For: Pet owners who value tank capacity and want specialized tools for liquid pet accidents and everyday stains.

Its 16 oz. clean tank and 13.5 oz. dirty tank are best suited to quick cleanups rather than long cleaning sessions.
The included 4-inch Tough Stain Tool gives you a useful cleaning width for carpet spots, stairs, upholstery, and car interiors.

- 4-inch Tough Stain Tool works well for targeted spot cleaning.
- Suitable for quick pet-mess cleanup on approved soft surfaces.

Factors to Consider When Choosing a BISSELL Portable Pet Carpet Cleaner
The best model depends less on a single power claim and more on the size of your usual messes, the surfaces you clean, the storage space you have, and how much maintenance you are willing to do after each use.
Cleaning Power and Efficiency
Portable spot cleaners work by spraying cleaning solution, agitating the stain with a tool, and extracting the dirty liquid. Strong suction helps recover more moisture, but stain age, carpet fiber, formula choice, and technique also affect the result. For fresh pet accidents, remove solids first, blot excess liquid, pretreat when appropriate, and make slow extraction passes without oversaturating the surface.
Size and Portability
The Mini is easiest to carry at 7 pounds, the Max Pet SmartMix weighs 8.2 pounds, and the Pet Deluxe weighs 9.7 pounds. A lighter machine is more convenient for stairs and car interiors, but larger tanks reduce interruptions. Choose the Mini for occasional small spots, the Max Pet SmartMix for a balance of size and features, or the Pet Deluxe when tank capacity matters most.
Tool and Accessory Options
Tool selection can matter as much as the machine itself. A standard Tough Stain Tool is useful for most carpet and upholstery spots. A Stain Trapper Tool helps isolate unpleasant liquid messes, while a HydroRinse or self-cleaning tool makes it easier to flush residue after use. Because bundles can differ by retailer, confirm the exact tools and formula bottles shown in the current listing.
Tank Capacity and Maintenance
Larger tanks are useful for multiple spots, stairs, and vehicle interiors, while smaller tanks reduce weight and storage needs. Regardless of model, empty the dirty tank promptly, rinse removable parts, flush the hose or tool as directed, and let components dry before storage. This helps reduce odors and residue buildup.
Surface Compatibility
Do not assume every carpet, rug, mattress, or sofa can be wet-cleaned. Check the manufacturer’s care label first. For upholstery, a W or WS code generally indicates compatibility with water-based cleaning, but you should still spot-test an inconspicuous area. Avoid using a portable extractor on fabrics labeled S or X unless the furniture manufacturer specifically approves it.
Formula and Water Use
Use a cleaning formula labeled for BISSELL portable carpet cleaners and follow the fill lines for your exact model. Use warm tap water when the manual permits it, not boiling water. Too much detergent can leave residue, so do not add extra formula beyond the recommended amount.
Price and Value Comparison
Do not compare these models by price alone. The Max Pet SmartMix adds formula-mixing convenience and rinse mode, the Pet Deluxe provides the largest tanks and specialized pet tools, and the Mini prioritizes low weight and storage. Check the current Amazon listing for bundle contents, warranty information, and availability before purchasing.
Brand Commitment and Support
BISSELL states that a portion of purchases supports the BISSELL Pet Foundation and its work helping pets in need. For product support, keep your receipt, record the model number, register the machine when possible, and follow the warranty terms supplied with the exact model and retailer.
Before You Clean: Vacuum or remove loose debris first, check the surface care label, spot-test the formula, and keep pets and children away from the damp area until it is fully dry.
Frequently Asked Questions
Can BISSELL Portable Carpet Cleaners Be Used on Upholstery?
Yes, on upholstery approved for water-based cleaning. Check the care label for a W or WS code, test a hidden area first, and avoid oversaturating the fabric. Do not use water-based extraction on S- or X-coded upholstery unless the furniture manufacturer approves it.
How Often Should I Use a Portable Carpet Cleaner?
Use it when a spot or spill occurs rather than following a fixed monthly schedule. Fresh stains are usually easier to treat than old stains. For whole-room cleaning, use a full-size carpet cleaner or professional service instead of repeatedly spot-cleaning large areas.
What Types of Pet Stains Can These Cleaners Treat?
They are designed for common spot-cleaning jobs such as urine accidents, vomit, muddy paw prints, tracked-in dirt, food spills, and other small messes. Results vary by stain age, surface material, formula, and cleaning technique, so complete removal is not guaranteed.
Are BISSELL Portable Cleaners Easy to Store?
Yes. All three are compact compared with full-size carpet cleaners, and the Mini is the easiest to fit into a small closet or cabinet. Before storage, empty and rinse the tanks, flush the hose or cleaning tool as directed, and allow damp components to dry.
Do BISSELL Cleaners Come With a Warranty?
BISSELL provides warranty coverage for its machines, but the term and conditions can vary by model and seller. Check the warranty information on the current product listing, keep your receipt, and register the cleaner after purchase when available.
Can a Portable Cleaner Replace a Full-Size Carpet Cleaner?
Usually not. Portable models are best for spots, stairs, upholstery, pet beds, and vehicle interiors. A full-size extractor or professional cleaning service is more practical for wall-to-wall carpet or an entire large sectional.
Conclusion
Choose the BISSELL Little Green Max Pet SmartMix for the best overall balance of convenience, tank size, and pet-focused features. Pick the Little Green Pet Deluxe when you want larger tanks and specialized tools for messier jobs. Choose the Little Green Mini when low weight, fast setup, and compact storage matter most.
Whichever model you choose, confirm the current bundle contents, follow the surface care label, and clean the tanks and hose after every use for the best long-term experience.
