I don't know what we're doing different in our house, but we have two vacuums that are supposed to be really great that we cannot use because of loss of suction. We've tried any number of times to do what the instructions say with no luck. We took one in to the vacuum repair and it worked for a couple sessions. . . We've been using a broom for years now.
One is a Dyson and needless to say, I'm frustrated. Anyone have any ideas?
