Haven't used the cleaner yet so I can't speak on the operation of it. Was disappointed with how it was shipped in. The rivets that rivet the side shield on were broke and had to be replaced. While redoing the rivets I crawled inside because I noticed a nut on one of the bolts holding the fan guard was off. Ended up having to cut and reweld all 4 bolts because they were all stripped. Hopefully the cleaner works better than ours was put together.
