Dyson is a great vac, but you have to keep the filters and everything cleaned ALL the time like after every use or it is no better than a 100 dollar black and decker vac IMO.
honestly, as far as cleaning is concerned... do the little things (as well as the big), like mirrors, dusting off the clocks, cleaining the window sills, cleaning the ceiling fans if they have them... the little things like that, that people don't think about very often is what really counts for a clean house and will get repeat business. I dusted off my ceiling fans last weekend and cleaned the window sills and light fixtures and I can't tell you how much cleaner the house feels now. just my opinion.
