Bought this less than a week ago when my Hoover finally gave up the ghost.  I purchased it because we have a Shark at the Veterinary Clinic where I work, and I know the abuse it gets and it just comes back for more.  Was it up for the job at my house where multiple cats reside??  Out of the box...super easy to assemble.  Turned it on and vacuumed and area that has already been vacuumed. Couldn't believe how much it picked up!  I've only had it for 5 days, but so far I'm happy.  Hope it lasts like the one at work.
