The Bissell Little Green Max Pet is a good fit for pet owners who need to clean small carpet and upholstery messes and want easier tool cleanup afterward. Its separate pet hair tool and one-touch hose and stain-tool cleanout are the main reasons to choose it.
Buy it for local spots, muddy paw marks and upholstery touch-ups. If your main job is cleaning whole carpeted rooms, a portable spot cleaner asks you to cover too much ground with a small tool.
The Bissell Little Green Max Pet at a glance
The Max Pet earns its place through pet-focused tools and easier rinsing after a mess. It combines spray, scrubbing and suction, with separate tanks for clean solution and recovered dirty water.
Bissell Little Green Max Pet: Best for frequent pet cleanup
- Self-cleaning Tough Stain Tool
- Pet Hair Removal Tool
- Two-tank design
- Corded electric
Choose the Max Pet for small pet messes when a separate hair tool and one-touch hose and tool cleanout would simplify your routine.
Pros
- One-touch hose and tool cleanout
- Separate Pet Hair Removal Tool
- Clean and dirty water stay in separate tanks
- Pet formula trial included
Cons
- Needs an outlet within reach
- Small spot-cleaning tool means more work across large areas
Bissell describes the cleaner as suitable for set-in pet messes, including muddy paw prints and embedded dirt. Treat the tool kit as the buying reason rather than expecting every stain to disappear in one session.
The included 8 oz trial formula is PET PRO OXY Spot & Stain with Urine Eliminator and StainProtect Technology. Bissell says this formula removes pet stains and helps protect against future stains; follow its directions for dilution, surface use and application.
Which Bissell Little Green Max Pet model is this?
The Little Green Max Pet reviewed here is model 3860, also identified as Little Green C2. Its body measures 8.3 in deep, 12 in wide and 11.5 in high.
Allow extra storage room for the hose, cord and tools. A shelf that fits the body alone may still leave you struggling to put everything away after use.
The Max Pet weighs 8.2 lb, while the Pet Deluxe and 1400B each weigh 9.7 lb. That 1.5 lb difference favors the Max Pet if you often carry the machine upstairs or out to a vehicle, though filled tanks add weight.
Who should buy the Max Pet, and who should skip it?
Choose the Max Pet for repeated small pet messes on wet-cleanable soft surfaces. Its tool combination makes the most sense when both hair and stains are regular parts of your cleanup routine.
It suits a home where a muddy patch on the carpet, a marked couch cushion or a dirty car seat needs attention between larger cleaning jobs. Keeping a portable machine nearby makes these limited tasks easier to tackle without bringing out a full-size cleaner.
The hose and tool cleanout also matters if the final rinse is the step you're most likely to put off. It gives you a built-in way to flush residue, although you still need to empty and care for the tanks.
Skip it if most of your cleaning involves whole rooms, large rugs or long stretches of carpet. A small extraction head means repeated passes, frequent repositioning and more time spent working close to the floor.
Also skip wet extraction on fabrics whose care instructions prohibit it. A pet label on a cleaner doesn't make it suitable for every couch, rug or car interior.
For occasional food spills without much pet hair, the 1400B is a sensible alternative. Choose the Pet Deluxe instead if its particular accessory kit better matches the jobs you expect.
How does the Max Pet compare with other Little Green models?
Choose among these models by the tools you'll use and how far you'll carry the machine. The Max Pet favors pet hair cleanup and integrated tool rinsing, while the alternatives offer different accessory combinations.
| Model | Main buying reason | Best match |
|---|---|---|
| Bissell Little Green Max Pet | Pet Hair Removal Tool and self-cleaning Tough Stain Tool | Frequent small pet messes |
| Bissell Little Green Pet Deluxe | Stain Trapper Tool plus standard stain and hose-rinsing tools | Buyers who want that specific pet accessory kit |
| Bissell Little Green 1400B | Standard stain tool and HydroRinse tool | General household spots and spills |
Bissell claims the Max Pet has 30% more suction power than a competitive portable deep cleaner. That comparison doesn't identify the Pet Deluxe or 1400B, so it isn't a reason to rank their cleaning power against each other.
Choose the Pet Deluxe for its accessory mix
The Pet Deluxe suits buyers who want the Stain Trapper Tool in the box alongside a 3-inch Tough Stain Tool and HydroRinse Self-Cleaning Hose Tool. Pick it because those tools match your routine, rather than simply because it carries a pet name.
Its 48 oz tank is useful when you plan to work through several spots in one session. You also get an 8 oz trial of PET Spot and Stain formula and an 8 oz trial of PET OXY Boost.
Read the formula directions before combining or using either product. Having two bottles doesn't mean you should improvise a stronger mix.
Skip the Pet Deluxe if you mainly want the Max Pet's separate hair tool or prefer fewer loose accessories. The included kit is only useful if you'll actually change tools for different jobs.
Choose the 1400B for routine household spots
The 1400B suits buyers whose main needs are ordinary carpet and upholstery spills. Its 48 oz clean-water tank, 3-inch Tough Stain Tool and HydroRinse tool provide a straightforward spot-cleaning setup.
It includes trial-size formula, and Bissell provides a one-year limited warranty. It's a practical choice when you want stain extraction without making a pet-focused tool kit your priority.
Skip it if the Max Pet's hair tool is the feature that brought you here. Buying a familiar model won't help if its included accessories miss your main need.

What should you check before buying?
Check surface compatibility, reach and storage before choosing a portable cleaner. These practical limits decide whether you can use the machine where your messes happen.
Start with the care directions for your couch, rug or vehicle seats. For upholstery marked with cleaning codes, W generally allows water-based cleaning, WS allows water-based or solvent cleaning, and S or X calls for a different approach.
Those codes are a starting point, so follow the furniture maker's directions for the whole item. Trim, backing and internal materials can need different care from the visible fabric.
Next, picture where the machine will sit while you clean. It needs a stable surface, enough hose reach and a suitable outlet without pulling the cord across a walkway.
Bissell describes the Max Pet's hose and cord as longer for hard-to-reach areas. Check their exact lengths before ordering if reaching your stairs or parked car will decide the purchase.
Finally, choose a storage spot near somewhere you can fill, empty and rinse the machine. Convenient cleanup matters more than squeezing it into the smallest possible cupboard.
How should you set up the Max Pet for a first cleanup?
Begin with surface care checks and correct solution mixing, then clean a hidden area before treating the visible stain. Use the manual for the Max Pet's controls, tank markings and tool connections.
Remove loose hair and dry debris first, using a method suitable for the surface. For a fresh spill, blot up excess liquid without grinding it deeper into the fabric.
Fill the clean tank to the instructed marks with the water temperature and formula amount the manual specifies. More detergent can leave residue and create excess foam, so don't strengthen the mix to chase a stubborn mark.
Use an approved machine formula rather than dish soap, laundry detergent or an improvised household mixture. Our guide to what you can put in a Bissell Little Green explains how to choose a suitable solution.
Seat the tanks securely and attach the correct tool before starting. Keep the machine upright and place it where moving the hose won't pull it toward an edge.
For the operating sequence, follow our guide to how to use a Bissell Little Green alongside the model's manual.
How do you clean a spot without soaking the surface?
Use small amounts of solution and slow extraction passes to clean a defined patch. The goal is to lift the mess while leaving as little moisture behind as possible.
Apply solution as directed, then agitate gently with the stain tool. Avoid hard scrubbing, which can distort fabric texture or spread a mark beyond its original edge.
Keep the suction opening in even contact with the surface as you draw the tool across it. Rushing or lifting one side lets air enter instead of pulling as much liquid through the fabric.
After the wet passes, make extraction passes without adding more spray, following the manual. Stop adding water once the patch is evenly damp rather than repeatedly soaking a stain that hasn't changed.
For pet urine, blot promptly and treat the source of the odor rather than just the visible ring. Urine that has reached carpet backing or padding can require attention beyond the surface.
Our guide to cleaning pet urine from carpet with a machine explains that process. A portable extractor can recover liquid from accessible fabric, but it can't make deeper contamination disappear by repeated spraying.
Let the area dry fully before returning cushions, covers or regular foot traffic. Air movement helps, and our guide to carpet drying after cleaning explains the main factors that affect drying.
What cleanup does the Max Pet need after each use?
Use the hose and tool cleanout after the job, then empty, rinse and dry the parts as directed. Self-cleaning describes the rinse feature, not a machine you can put away full of dirty water.
Follow the manual's cleanout sequence so the rinse reaches the intended cleaning path. Remove trapped hair or debris from accessible areas without taking apart parts the manual doesn't tell you to remove.
Empty the dirty-water tank promptly and rinse away collected soil. Check the tank lid, seals and accessible tool openings for residue before putting the parts back together.
Let washable parts dry in the way the manual recommends before closing everything for storage. Leaving dirty water or damp debris inside can create odors that make the next cleanup less pleasant.
Keep the hose and cord arranged without tight bends or strain at their connections. Our guide to cleaning a Bissell Little Green after use covers the care routine in more detail.
Which common mistakes should you avoid?
The main mistakes are overwetting, overusing formula and skipping cleanup. Each can turn a small stain job into extra rinsing, longer drying or an unpleasant machine to reopen.
- Using the extractor like a vacuum: Remove loose dry debris first so wet cleaning focuses on the stain.
- Pressing and scrubbing too hard: Work gently and keep the suction opening flat against the surface.
- Spraying on every pass: Include extraction-only passes instead of adding liquid throughout the job.
- Chasing a fixed stain with more water: Stop and reassess if repeated passes aren't changing the mark.
- Treating every fabric alike: Check care directions for each item, even when another couch or rug cleaned well.
- Storing dirty water until later: Finish the tank and tool care while the machine is already out.
Is the Bissell Little Green Max Pet the right choice?
Choose the Bissell Little Green Max Pet when pet hair, small wet-cleanable messes and quick tool rinsing define your routine. Its lighter body also makes it the more appealing choice here for frequent trips between floors or out to the car.
Choose the Pet Deluxe when you specifically want its Stain Trapper accessory kit. Choose the 1400B when routine household spots are your main job and its standard tool setup covers what you need.
If your real task is whole-room carpet cleaning, choose the machine format for that area before comparing portable accessories. For a final check on how often you'd use one, read is a Bissell Little Green worth it?.
