Avoid this rip-off - Took my Rainbow Vacuum to have a brass separator nut removed, that's all - vacuum was 100% operational only needed this nut removed to take off the filter - the ""salesman"" said that it could be done when his technician came in, that we should leave it after paying a $50 service charge. We thought ok if the ""Salesman"" could guarantee that the brass separator was removed. He said he guaranteed it and would phone us the next day. Well, 3 days later, no phone call, we called and were told that the nut could not be removed, that we needed $400 in repairs. We asked for our $50 back, but the ""Salesman"" said no that he was not going to return it, that the technician spent time determining that the nut would not come off. Well we are furious and will never go back there. We took it to another repair shop in Roxborough, and he took the nut off and didn't charge us anything.
