Questions and Answers

    Why is my Tennant T7AMR leaving water behind?
    • D
      Dennis SheppardAug 18, 2025
      If your Tennant Scrubber is leaving water behind, it could be due to several reasons. The vacuum fan might be off, so ensure it is turned on. Check the squeegee blades for wear and rotate or replace them if needed. The squeegee might be out of adjustment, requiring adjustment. Other potential causes include a clogged vacuum hose (flush the hoses), a dirty vacuum fan filter (clean the filter), worn vacuum fan cover seals (replace the seals), debris caught on the squeegee (remove the debris), a disconnected or damaged vacuum hose (reconnect or replace), or a recovery tank cover that is not completely closed (check for obstructions and close the cover).

    How to fix trailing water with poor pickup on my Tennant T7AMR?

      To address trailing water with poor or no water pickup in your Tennant Scrubber, several factors could be at play. First, ensure the vacuum fan is turned on. Check if the squeegee is in the raised double scrub position and lower it if necessary. Inspect the squeegee blades for wear and rotate or replace them. Also, make sure the squeegee is properly adjusted. Other potential causes include a clogged vacuum hose (flush it to resolve), a dirty vacuum fan filter (clean it), worn vacuum fan cover seals (replace them), debris caught on 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 sealed).

    Why is there little or no solution flow in my Tennant Scrubber?
    • D
      David HuffmanAug 23, 2025
      If your Tennant Scrubber has little to no solution flow, start by checking if the solution tank is empty and fill it if needed. Ensure the solution flow is turned on. If the solution supply lines are plugged, flush them. Also, inspect the solution tank filter for clogs; if clogged, drain the solution tank, remove the filter, clean it, and reinstall.

    What to do if Tennant Scrubber has no solution flow?
    • R
      Richard SmithAug 26, 2025
      If your Tennant Scrubber has little or no solution flow to the floor in conventional scrubbing mode, start by checking if the solution tank is empty and fill it if necessary. Ensure that the solution flow is turned on. Another potential issue is plugged solution supply lines, which can be resolved by flushing them. Also, inspect the solution tank filter for clogs; if clogged, drain the solution tank, remove the filter, clean it, and reinstall it.

    What to do if my Tennant Scrubber has poor scrubbing performance?
    • Q
      qfordAug 28, 2025
      If your Tennant Scrubber isn't scrubbing well, there are several things to check. Make sure the 1-Step button is on. The recovery tank might be full (empty it) or the solution tank might be empty (fill it). Also, check for debris caught on the scrub brushes or pads and remove it. Inspect the scrub brushes for wear and replace them if necessary. If the brush pressure is too light, increase it. Finally, ensure the batteries are fully charged.

      If the vacuum fan on your Tennant Scrubber won't turn on, first check if the vacuum fan switch is turned off and turn it on. If the recovery tank is full, drain it. Foam filling the recovery tank can also cause this issue, so empty the recovery tank. The recovery tank sensor might be dirty or stuck; in that case, clean or replace the sensor.

    • B
      blacktinaSep 4, 2025
      If your Tennant Scrubber's scrubbing performance is poor, several issues could be the cause. Make sure the 1-Step button is activated. Also, check if the recovery tank is full and empty it if needed. Ensure the solution tank isn't empty by refilling it. Other possible causes include debris caught on the scrub brushes or pads (remove any obstructions), worn scrub brushes (replace them), brush pressure set too lightly (increase it), or a low battery charge (charge the batteries fully).

    Why won't the vacuum fan turn on my Tennant Scrubber?
    • L
      Lori FloresSep 7, 2025
      If the vacuum fan on your Tennant Scrubber won't turn on, first verify that the vacuum fan switch is turned on. If it still doesn't work, the recovery tank might be full and needs to be drained. Another possibility is that foam is filling the recovery tank, in which case you should empty it and use less detergent. Finally, the recovery tank sensor might be dirty or stuck, requiring cleaning or replacement.
