Why is the Nilfisk-Advance Scrubber leaving water behind?
- C
  Cody TuckerAug 12, 2025
  If the Nilfisk-Advance Scrubber isn't picking up water effectively, several factors could be at play. The squeegee blades might be worn or torn, in which case you should reverse or replace them. The squeegee may also be out of adjustment; ensure it touches the floor evenly across its entire width. Other potential causes include a full recovery tank (empty it), a leak in the recovery tank drain hose (secure the cap or replace the hose), a leak in the recovery tank cover gasket (replace the gasket or properly seat the cover), debris caught in the squeegee (clean the squeegee tool), a clogged vacuum hose (remove the debris), using too much solution (adjust the solution flow at the control panel), or a foam filter cover that is not seated properly (seat the cover correctly).

  If your Nilfisk-Advance Scrubber isn't scrubbing well, the issue could stem from several causes. First, check the brush or pad for wear and rotate or replace the brushes if needed. Ensure you're using the correct type of brush or pad. Also, verify that you are using the correct cleaning chemical. If the machine is moving too fast, try slowing down.

  If your Nilfisk-Advance Scrubber has no or inadequate detergent flow (EcoFlex models only), start by checking if the detergent cartridge is empty and fill it if necessary. Inspect the detergent flow line for any plugs or kinks; purge the system and straighten the lines to remove any kinks. Make sure the dry seal cap on the detergent cartridge is properly sealed by reseating it. Lastly, verify that the detergent pump wiring is correctly connected or reconnected.

  If your Nilfisk-Advance Scrubber isn't providing enough or any solution, there are a few things to check. Begin by ensuring the solution tank isn't empty and fill it if needed. Inspect the solution lines, valves, filter, or trough for clogs; flush the lines and trough, and clean the solution filter. Verify that the solution shutoff valve is open. Lastly, inspect the solution solenoid valve and clean or replace it if necessary.

Why does my Nilfisk-Advance Advance Advenger 2800ST Scrubber vacuum shut off with a full tank indicator when the tank is empty?
- M
  Michael RosarioAug 27, 2025
  If the vacuum on your Nilfisk-Advance Scrubber shuts off and the display shows “Recovery Tank FULL indicator” even when the recovery tank is not full, the issue might be due to a plugged squeegee hose; clear any debris. It could also be caused by vacuuming large amounts of water at a high travel speed; slow down.
