Why is my Nilfisk-Advance Advance SC901 ST-34D leaving water behind?
- D
  Dylan SmithAug 5, 2025
  If your Nilfisk-Advance Scrubber isn't picking up water well, several factors could be the cause. Check for worn or torn squeegee blades and reverse or replace them if necessary. Ensure the squeegee is adjusted correctly so the blades touch the floor evenly. Also, inspect for clogs or missing squeegee seals, cleaning or replacing them as needed. Make sure the recovery tank isn't full and that the drain hose and cover gasket are secure and not leaking. Remove any debris caught in the squeegee or clogging the vacuum hose. Adjust the solution flow to avoid using too much, and empty the debris catch cage.
