I recently purchased this machine to do some commercial cleaning. Sadly the job I intended to use it for wound up going with in house cleaning because it was cheaper than my rate. The machine has only been used a couple of times for a short period of time. I washed the bag not that it needed it, but because it was dusty from sitting, I pulled off the hood and snapped a pic of the commutator so you can see that it is still like new. I paid $225 from my dealer and am looking to sell it for 125 plus shipping which I'm at a $100 loss. So my loss is your gain
