  If you're experiencing insufficient recovery water vacuuming with your Nilfisk-Advance Scrubber, it could be due to several reasons. The recovery water tank might be full, so try emptying it. The hose could be disconnected from the squeegee; if so, reconnect it. Also, the vacuum grid could be clogged, or the float stuck closed, so clean the grid or check the float. The squeegee itself might be dirty, or the blades could be worn or damaged, requiring cleaning and inspection. Finally, ensure the tank cover is correctly closed, the gasket isn't damaged, and the compensation hole isn't clogged. Close the cover correctly, replace the gasket or clean the compensation hole.

  If your Nilfisk-Advance Scrubber is leaving marks caused by the squeegee, there might be debris under the squeegee blades, so remove any debris. The squeegee blades could be worn, chipped, or torn, indicating they need replacement. Alternatively, the squeegee may not be balanced with the handwheel; if so, balance it.

  If there's insufficient solution flow to the brushes of your Nilfisk-Advance Scrubber, the solution filter or the clean water filter might be dirty; clean the filter. Alternatively, the tank could be dirty, with the drain hole clogged; clean it.
