What to do if my Advance acoustic Scrubber has poor water pick-up?
- S
  Samantha LarsenJul 31, 2025
  If the Advance acoustic Scrubber isn't picking up water effectively, there are several potential causes. The squeegee blades might be worn or torn, in which case you should reverse or replace them. The squeegee might be out of adjustment; adjust it so the blades touch the floor evenly. The recovery tank could be full, so empty it. Check for leaks in the recovery tank drain hose or cover gasket, and secure the drain hose cap or replace the hose or gasket if needed. Debris might be caught in the squeegee; clean the squeegee tool. The vacuum hose could be clogged; remove any debris. You might be using too much solution; adjust the solution flow at the control panel. Finally, the debris catch cage could be full; empty it.

  If your Advance acoustic Scrubber's scrubbing performance is poor, the brush or pad might be worn, so rotate or replace the brushes. You might be using the wrong brush or pad type or the wrong cleaning chemical; consult Advance. You might be moving the machine too fast; slow down. You might not be using enough solution; increase the solution flow at the control panel.

  If your Advance acoustic Scrubber (Cylindrical System) exhibits poor sweeping performance, start by emptying and cleaning the hopper, as it may be full. If the hopper isn't the issue, inspect the brushes for wear and replace them if needed. Additionally, if the bristles have taken a set, rotate the brushes to improve performance.

  If there is no detergent flow in your Advance acoustic Scrubber (EcoFlex models only), first check if the detergent cartridge is empty and fill it if necessary.
