I"ve been using Hoover Self-propelled beater brush uprights for years and years. Seem to clean ok and CR has always rated them as high as anything else including Dyson. In fact, last time I looked, some years ago, the Dyson didn't rate all that high.
There's been an ad running on TV a lot lately about a Dyson DC-41 that claims it has "twice" the suction. Has anyone got any long term experience with the Dyson's compared to the Hoovers? Which did you like the best?
