The Dyson Root 6 really sucks. But that's a good thing. Thanks to Dyson's patented Root Cyclone technology, the Dyson Root 6 ($150; Oct. 23) will probably be the only handheld that will never clog or lose suction. The Dyson Root 6 has twice the suction of other handhelds, and uses a rechargeable lithium ion battery and comes with a specially designed combination brush/stair tool for cleaning. Plus, it just looks like it can shoot powerful laser beams with the push of a button.
