BISSELL Little Green ProHeat SmartMix Portable Deep Cleaner 3935

Powerful, portable cleaning with smart technology

The BISSELL Little Green ProHeat SmartMix is a compact deep cleaner designed for quick, targeted work on carpets, upholstery, car interiors, and other soft surfaces. Its ProHeat Technology heats the cleaning solution to 120°F in under 30 seconds, helping to lift stubborn stains and reduce odors as you work. The combination of heat, suction, and focused tools makes everyday messes feel manageable rather than overwhelming.

SmartMix Technology automatically blends water and formula as you clean, so you get the right strength without measuring. A dedicated Rinse Mode lets you switch to a water-only cleaning pass when a lighter touch is desired, helping you customize outcomes based on the mess you encounter.
