  I have the Dyson Animal with the ball, it worked great until I got new carpet and I can't push it over the carpet.  I called the company and they said you can't adjust that particular model, it's self adusting, so it doesn't work on many of the new carpets.    Other Dysons don't have this problem, but if I had known about this when I bought the $500.00 machine, I wouldn't have gotten it!  The Dyson is well made, but I think there are now other machines that are just as good and better priced.  Don't know anything about the Shark, except someone was raving about the steam cleaner at the store, so she bought the vacumm, it's a cute machine!  |
