Tried to put this in last week-but the internet problems I was having seems to have prevented it from working.Well I'll try again.On the weekend of the 21st-(for you vac folks-the day the Dyson "Ball" was introduced to market)Went to Best Buy-There it was!!The salesman asked me if I wanted to try it-so I obliged him-Found that pretty plastic vac to be quite interesting.Got out the BB card and got my own.Now that I have had the vac for over a week-found it it be quite an improvement over previous Dyson machines.That "ball" serves as a rear wheel,steering device,and suction motor housing.Its a two motor upright-one for suction-other motor for the brush bar.Like the Royal powercast you can turn the beater bar motor off and use the machine for bare floors or delicate rugs and carpet.Also the beater bar motor automatically shuts off when the machine is fully upright-and in the "hose" mode.Rear stabilizor wheels come ut to hold the machine up-it cannot rest on the "ball" alone or it would tip over.I know its a "plastic" vac-but and interesting one at that-a new innovation in vac design-Try one at BB or one of the other Dyson dealers-you may want to "roll" one home with you-good for us vac collectors out there.The machine does work pretty well-the beater bar has been redesigned for American carpets.It is gear driven and comes out of the machine in two sections-you undo two endcaps on the floor nozzle and you can take the sections out for cleaning or replacement.
