Input:
I love this vacuum.  I had a very old eureka world vac and nothing worked as well until I bought this vacuum.  I have two cats and have hardwood and tile floor throughout the house.  This vacuum is lightweight, quieter than my old vacuum, and picks up dirt and cat hair like no other vacuum (since my old world vac).  I am very happy with this purchase and am considering a second one for the downstairs, even though it is extremely easy to carry up and down the stairs.
