If you have pets, carpet messes aren’t a matter of if—they’re a matter of when.
Having put both the Bissell Little Green Max Pet and the Bissell ProHeat 2X Revolution Pet Pro Plus through their paces in a house full of muddy paws and accidental spills, I can tell you right off the bat: they serve two completely different purposes.
If you are trying to decide which one to buy without wasting hours reading endless spec sheets, this quick guide breaks down everything you need to know.
Quick Verdict & The Overall Winner
🏆 The Overall Winner: Bissell ProHeat 2X Revolution Pet Pro Plus
The Little Green Max Pet handles quick spot cleanups well. The ProHeat Revolution Pet Pro Plus tops them all. It offers full-room carpet deep cleaning while also including an 8-foot hose and pet upholstery attachments. It gives you the best of both worlds: whole-home floor restoration plus spot cleaning capabilities.
Buy the Little Green Max Pet if: You live in an apartment, have mostly hard floors with just a few rugs/furniture pieces, or want an easy tool for car interiors and stairs.
Buy the ProHeat Revolution Pet Pro Plus if: You have wall-to-wall carpets, multiple rooms to deep clean, or stubborn ground-in pet stains that require heavy-duty motorized scrubbing.

Difference Overview: How They Perform in Real Life
1. Form Factor & Portability
- Little Green Max Pet: At just 8.2 lbs, this unit is extremely portable. I can easily grab it with one hand, carry it upstairs, or set it inside a car footwell.
- ProHeat Revolution Pet Pro Plus: At 17.5 lbs, it feels like a sturdy upright vacuum cleaner. It rolls effortlessly across floor carpets, but carrying it up and down stairs takes more effort.
2. Cleaning Power & Mechanism
- Little Green Max Pet: Relies heavily on formula, hose suction, and your own elbow grease. You spray the stain, scrub with the hand tool, and suction up the liquid.
- ProHeat Revolution Pet Pro Plus: Features Dual DirtLifter PowerBrushes that rotate under motor power, pulling up ground-in dirt from deep inside carpet fibers without requiring manual scrubbing.
3. Extra Features That Actually Matter
- Express Clean Mode (ProHeat): Carpets dry in roughly 30 minutes, which is a lifesaver when you can’t block off a room for hours.
- CleanShot Pretreater (ProHeat): A foot pedal sprays a concentrated stream of formula directly onto tough spots like dried urine or skunk odors before you run the machine over them.
- Hose Cleanout (Little Green Max): Rinsing out pet hair and debris from inside the hose after cleaning takes just a single button press.
