Why is the dirty water vacuuming insufficient in my Nilfisk-ALTO Scrubber?
- C
  Christopher HarrisonAug 1, 2025
  Insufficient dirty water vacuuming in your Nilfisk-ALTO Scrubber can be caused by a few things. The recovery tank might be full and needs emptying. The squeegee bars could be dirty, or the blades might be worn or damaged, so you should clean and check them. Also, the inspection compartment could be dirty and require cleaning. Check if the vacuum hose is disconnected or dirty, and connect or clean it. Finally, the air filter might be dirty and need cleaning.
