  If the recovery water vacuuming is insufficient, it might be due to several reasons. First, check if the recovery water tank is full and empty it if necessary. Next, ensure the hose is connected to the squeegee; if it's disconnected, connect it. Also, inspect the vacuum grid for clogs or a stuck float and clean the grid or check the float. Examine the squeegee for dirt or damage to the blades; clean and check the squeegee. Lastly, verify that the tank cover is properly closed and the gasket is intact; close the cover or clean/replace the gasket.

Why is the solution flow to the brush insufficient in my Nilfisk-ALTO SCRUBTEC 545B Floor Machine?

  Jennifer NewmanAug 15, 2025
  An insufficient solution flow to the brush could be due to a dirty solution/clean water filter; clean the filter. The tank might be dirty, causing the drain hole to clog, so clean the tank. If your model has a Chemical Mixing System, the tank might be dirty or clogged; clean it using the drain cycle.

  If the squeegee leaves marks on the floor, start by checking for any debris under the squeegee blades and remove it. If the blades are worn, chipped, or torn, replace them. Also, ensure the squeegee has been properly adjusted with the handwheel; if not, adjust it.

Why do the warning lights (81) flash simultaneously on my Nilfisk-ALTO Floor Machine?

  If the warning lights flash simultaneously, the brush deck motor may be overloaded. Try using a less aggressive brush suitable for the floor or avoid working with the extra pressure function turned on.
