For those of us with pets I highly recommend the Dyson Dg-15 Animal If you are smart and have a credit card you can buy it for around 458.00 online, {I will not post the site as I am not a commercial for any online site}
If you try to purchase it in a store get ready to part with 650.00 or more for the same unit.
I had a bag less hoover wind tunnel {stolen from Dyson after they turned his design down} {they were sued by Dyson in 1999 and he won BTW, for Patent infringement}
Anyways after getting the ANIMAL I vacuumed one small area of my carpet, around a 10 by 10 area with the hoover till I felt it was free of all dust or any other items such as cat hair, then I went over it with the ANIMAL, I was amazed at the amount of hair and dust the ANIMAL pulled out of the same area. This particular model has a ball for "legs" and turns on a dime around corners no more "muscling" around furniture and no more going over the same spot over and over one or two passes and the rug is clean.
It empties very easy and has a permanent filter; the filter rinses clean with clear water when needed.
This unit is a must for any homemaker!!!!
10 out of 10 for handling
10 out of 10 for its very quiet motor
10 out 0f 10 for its cleaning ability!
