I bought this to use in our caravan, as it had a 12v facility. Initially, we remarked on how heavy it was, then how noisy. On trying to install it in the caravan, the connection in the wall mounting wasn't long enough to make contact with the socket in the back of the cleaner, but then the socket in the cleaner actually broke off and fell inside the housing. My husband attempted a repair, without success, but I'd never liked it from the start, so we just threw the whole thing out and put it down to experience. It was pretty useless at vacuuming up bits and fluff and stuff anyway!
