Possible Causes

Dirty recovery tank not cleaned after use, Standing water in hoses, Contaminated brush roll, Clogged and moldy filters

How to Fix / Troubleshooting

Safety: Unplug the Husqvarna carpet cleaner. Use gloves when handling dirty water and mold.

  • Deep clean tanks: Wash the clean and recovery tanks with hot water and mild detergent. Rinse thoroughly and allow to dry.
  • Sanitize hoses and nozzle: Run a solution of warm water and a small amount of white vinegar through the solution system, then flush with clean water. Wipe the suction nozzle and hose interior where accessible.
  • Clean or replace filters: Wash foam filters and replace any paper or HEPA filters that smell musty.
  • Dry after use: Leave tanks and lids off the unit after cleaning so they can air dry, reducing odor buildup.
