    Why does my Tennant R14 Floor Machine have no power?
    • K
      Kim ElliottAug 16, 2025
      Your Tennant Floor Machine might not have power for several reasons: the key might be turned off (turn it on); the batteries may be discharged (recharge them); the battery cable could be loose or disconnected (secure the connections); the circuit breaker may have tripped (reset the 5 A circuit breaker); or the main fuse might be blown (replace the 100 A main fuse).

      If your Tennant Floor Machine isn't picking up water well, it could be due to several reasons. You may have worn ReadySpace rollers (replace them), clogged vacuum shoes (clean them), missing vacuum shoe springs (replace them), a loose recovery tank drain hose cap (tighten it), a loose or disconnected vacuum hose (connect hose cuffs securely), a clogged vacuum hose (remove the debris), a defective vacuum hose (replace it), the recovery tank cover not down (close it), or a worn tank cover gasket (replace it).
