The Hoover Wind Tunnel Cyclonic 12 Amp Vacuum makes cleaning a breeze.  This model has a convenient cord rewind.  This model has 3 positions, upright, and 2 lower positions for getting under tables and other furniture. 

I have an Australian Shepherd, and they have alot of hair.   That hair is no match for the Hoover Wind Tunnel.  The dirt cup really fills up rather quickly, but it is easy enough to remove and empty.  There are several attachments which make reaching higher places or small spaces easier. 

The brush roll can be turned on and off by using your foot on the convenient button...
