Query: surprisingly powerful lightweight vacuum

I bought this product because I wanted a lightweight vacuum for in-between cleaning with my cannister. I was surprised by the power and cleaning ability of this small vacuum. I have two cats and this machine picked up more hair, etc than my cannister cleaner. The motorized brush is as good as any other I've used. The head is smaller than a full sized vacuum and of course it doen't hold as much dirt in its cup, but it still does the job very well and you don't have to lug a heavy cannister up and down the stairs. Only have it for a short time, but I highly recommend it.
