I borrowed this vacuum, along with a carpet cleaner, from a friend to do some more serious whole house cleaning after several months of relentless illness for the whole family. I was greatly impressed with how powerful this was compared to my old Shark vacuum. With my old vacuum, I was usually left still finding escaped crumbs, and cleaning tangled hair and fur off the roller with each cleaning. This WindTunnel left my floors more clear of debris than I may have ever seen. Definitely pricing one of these into my budget so I can maintain such cleanliness.
