For sale is a TENNANT 3640 FLOOR SWEEPER SCRUBBER with charger. Runs good. The hourmeter shows 355 hours, however, we will be using it to sweep our warehouse until it sells, so you may see a higher reading on the meter. Comes with a SCR charger. Charges, runs, and sweeps floors. I am not a professional sweeper repairman and cannot evaluate it, beyond just using it around my shop to clean it. We bought it from a factory that closed down. I was told that it works fine.
