Before You Start

Prepare a clean workspace and have towels handy to catch drips. Unplug the unit before disassembly. Empty and rinse the dirty-water tank, then rinse the clean-water tank if necessary. Inspect seals and hoses for cracks or wear. Avoid using hot water or bleach on the machine components, which can damage seals and internal parts.

Estimated time: 15–30 minutes for a full cleaning session, depending on how dirty the unit is. If you notice persistent odors after cleaning, a deeper rinse cycle or replacement parts may be required.

Step-By-Step: How To Clean A Bissell Little Green Machine

Unplug the machine and detach the dirty-water tank and clean-water tank from the body.
Empty both tanks and rinse with warm water to remove residual solution and debris.
Rinse the hose and the inline spray nozzle by running warm water through them to clear clogs.
Wash the exterior surfaces with a damp cloth. If needed, use a mild detergent and then wipe dry.
Remove the upholstery cleaning nozzle and scrub it with a soft brush and mild detergent. Rinse thoroughly.
Inspect seals and gaskets for wear. Replace any cracked or missing seals using the Bissell Little Green Machine replacement parts kit if necessary.
Refill the clean-water tank with warm water and a small amount of carpet cleaner solution for handheld machine Bissell according to product directions.
Reassemble the unit, power on, and run a quick test on a cloth or towel to verify proper suction and spray.
Perform a short spray-and-pump cycle to ensure the nozzle is delivering solution evenly and the suction is clear.
Store the machine in a dry area, with the nozzle attached and the hoses free of kinks.
For stubborn stains, repeat the cleaning cycle on the affected area, using the upholstery nozzle and the recommended solution.

Common Mistakes

Skipping the rinse after cleaning the tanks, which can lead to odor buildup.
Using high-temperature water beyond manufacturer guidelines, risking seal damage.
Forgetting to remove debris from the nozzle and hose, causing clogs during future use.
Overfilling the clean-water tank or using incorrect cleaning solutions, which can reduce performance.

Tips For Best Results

Use the upholstery nozzle on fabrics and cushions for targeted cleaning without excess moisture.
Pre-treat stubborn stains with a small amount of solution before using the machine to improve results.
Run a quick test cycle on an inconspicuous area to verify colorfastness and fabric safety.
Keep a consistent spray-to-suction rhythm to prevent over-wetting surfaces.
Label and store replacement parts so they’re ready when maintenance is needed.

Call A Professional

Consider contacting a professional if you notice persistent leaks, motor overheating, or loss of spray pressure that cannot be resolved with routine maintenance. Stop using the machine if you observe unusual noises, burning smells, or visible damage to electrical cords or hoses. A trained technician can diagnose internal issues and safely replace worn components.
