Bissell Little Green 1400B

A compact spot and upholstery cleaner that handles the spills, pet accidents and car seats most households deal with far more often than whole-room carpet cleaning.

Not for: Anyone needing to deep-clean whole rooms of wall-to-wall carpet, which is slow and tiring with a small portable tank.

BISSELL Little Green 1400B

Compact, portable spot cleaner with spray-and-extract cleaning for carpet stains, upholstered furniture, stairs, and car interiors.

Not for: Whole-room carpet cleaning or dry vacuuming.

Which one fits you

frequent pet accidents

Bissell SpotClean Pro (line)

A larger tank and stronger suction than the Little Green pull more urine and moisture out of carpet pads and upholstery.

Not for: Small apartments with tight storage that only need occasional spot work.

cordless spot cleaning

Bissell Little Green Cordless (line)

Removing the cord makes quick cleanups on stairs and in cars faster.

Not for: People who clean large stained areas in one session, because battery runtime is limited.

Check before you buy

Spot vs. full-size. Choose a portable unit for spills, stairs, upholstery and cars. Choose an upright for cleaning entire rooms. Each type does the other's job poorly: portables are slow over large areas, and uprights are clumsy on furniture.
Separate clean and dirty tanks. Prefer models with two removable tanks that are easy to rinse. Dirty-tank odor and mold are the most common long-term complaints.
Hose and tool reach. Look for a hose long enough to reach the top of a stair or the back of a sofa from where the unit sits. A short hose means constantly lifting the machine, which defeats the purpose of a portable.
Suction / extraction. Do slow dry passes after each wet pass, and judge a machine by how damp the fabric stays afterwards. Weak extraction leaves wicking stains and a musty smell.

Questions

Does HeatWave mean the machine heats water?

No. Bissell HeatWave only helps hold the temperature of hot tap water you add. It does not heat cold water.
