There has been one of those the last few times I went to Habitat. I thought it was interesting because I had wondered if they made a bagless that was self propelled.
Not a big fan of Hoover's earlier bagless uprights, and I really prefer the bagged. I particularly like the later blue, silver or alien green models. If I see a good bagged one for a good price I'll get it.
It is funny because about 4-5 years ago many if not most of the vacuums I would see put at the curb would be bagged Self Propelled Windtunnels. Now all I tend to see is bagless Bissells, Hoovers, and Dirt Devils.
