We bought our Sharky vacuum about 3 years ago. It's one of those no bag set-ups, that gives you the instant reward of seeing exactly how much stuff builds up in your carpet. And when you have 2 dogs and 2 cats living in your house it piles up fast. (Thank goodness Izzy has schnauzer hair that doesn't shed as much as dogs with regular fur coats.)
Overall I like the job the Sharky does, I just wish they had used better material. Vacuums shouldn't begin falling apart after only 2 years. I heard from a coworker that Dysons suffer from the same fault. Maybe I should've hung onto the ugly, yet sturdy, Stark vacuum we bought with wedding $$.
