Topic "Bona Powerscrubber problems" a message from classicfloors

I have a Bona power scrubber that is just about a year old. I am the only one who has run the machine and I have used it between 15 and 20 times. When it's working it works very well. My problem is that it often doesn't seam to be working properly in that it won't squirt the cleaning solution out, especially when the vacuum in running. The pump will make a really loud noise and then quiet down when it starts to squirt. I have also have had 2 pumps that have completely failed. I have more pumps waiting at my distributor but I am wondering if it is something wrong with the machine wiring or circuitry that could be causing the erratic pump operation and frequent failure? Has anyone else had anything like this happen?


Thanks, Tucker
