      If your Nilfisk-Advance Scrubber isn't powering on, check the Machine Battery Connector to ensure it's connected. Look for a tripped 5 Amp circuit breaker and reset it after checking for a short circuit. Replace the Main Fuse if it's blown. Also, make sure the charger is unplugged.

      If you're encountering Magnetic SmartKey errors with your Nilfisk-Advance Scrubber, ensure a Magnetic SmartKey is present on the SmartKey Reader. If the key cannot be read, clean both the SmartKey and the SmartKey Reader with a clean cloth. Depress the SmartKey between your thumb and forefinger to insure free movement of the magnet. If a Restricted User Key Indicator appears, use a SmartKey programmed for this machine.

    Why is my Nilfisk-Advance Liberty SC50 leaving water behind?
    • W

      If the Nilfisk-Advance Scrubber isn't picking up water effectively, several factors could be at play. First, ensure the vacuum hose is securely connected to the squeegee assembly. Check the squeegee blades for wear or tears and reverse or replace them if necessary. Adjust the squeegee so the blades make even contact across the floor's width. Also, remember to empty the recovery tank when full. Check the Recovery Tank Drain Hose and Cover gasket for leaks. Clear any debris from the squeegee and the recovery hose. Reduce the solution flow from the control panel and ensure the vacuum is turned on and set to high.
