I remember those!
Those were competitors to the Hoover V2 which came out eariler with two brushrolls. My understanding is the V2 was very unreliable and Hoover took them off the market farily quickly. Those later became the Hoover Savvy, which had only one brush roll. I've nenver seen a V2 in working condidtion myself, but working Savvys do appear every so often. I do remember seeing those Kenmores at Sears briefly when new, but I've never seen one in the wild. My guess is most of the suffered the unforuncate same fate as the Hoover V2.
