Why is the Nilfisk-Advance Floor Machine recovery water vacuuming insufficient?

  Kimberly JenkinsAug 1, 2025
  Insufficient recovery water vacuuming in your Nilfisk-Advance Floor Machine can occur for several reasons: the recovery tank might be full (empty the tank); the hose might be disconnected from the squeegee (connect it); the vacuum grid could be clogged, or the float might be closing (clean the grid or check the float); the debris tray could be clogged (clean it); the squeegee might be dirty, or the blades worn or damaged (clean and check the squeegee); or the tank cover might not be properly closed, or the gasket is damaged (close the cover properly or replace the gasket).
