  If the scrub vacuum fan on your Tennant Floor Machine isn't turning on, first check if the vacuum fan/squeegee button is activated. If the recovery tank is full, drain it. Foam in the recovery tank can also cause this issue, so empty the tank. You may need to use less detergent or a defoamer. Lastly, the recovery tank sensor might be dirty or stuck; try cleaning or replacing it.

  If the Tennant Floor Machine leaves water behind, several factors could be at play. First, ensure the vacuum fan is turned on. Check the squeegee blades for wear and rotate or replace them if needed. Adjust the squeegee if it's out of alignment. Adding detergent to the solution tank can also help. Other potential issues include a clogged vacuum hose (flush it), a dirty vacuum screen (clean it), worn recovery tank cover seals (replace them), debris caught in the squeegee (remove it), a disconnected or damaged vacuum hose (reconnect or replace it), or a recovery tank cover that isn't completely closed (check for obstructions and ensure it's properly closed).

  If your Tennant Floor Machine's scrub vacuum fan won't turn on, start by checking if the vacuum fan/squeegee button is activated and turn it on if it’s off. If the recovery tank is full, drain it. Foam filling the recovery tank can also prevent the fan from turning on, so empty the tank. Sometimes, the issue might be a dirty or stuck recovery tank sensor; clean or replace the sensor. Consider using less detergent or a defoamer to prevent foam buildup.
