This is the patented canister vacuum with a central steering mechanism that rotates 360º, mimicking a user's movements as it follows nimbly behind. Unlike bulky typical canister vacuums that lumber along on narrow wheels and tip over around corners, this model features a central ball that can turn on the spot and fluidly change directions. A low center of gravity provides stability, while a flexible cuff absorbs shocks and realigns the canister as it is pulled. The quiet yet powerful 1,300-watt motor captures more dirt than common canister vacuums thanks to patented cyclonic technology that does away with bags that can clog and cause a loss of suction. The vacuum's powered floor tool is controlled from the handle--an industry first--eliminating the need to stoop to switch it on or off, and interchanges with a smaller powered head to remove pet hair from furniture. The unit's lightweight wand adjusts from 21"-34" long, a permanent HEPA filter traps dust and allergens, and a bagless design enables push-button emptying of the removable 0.53-gallon clear polycarbonite chamber. Plugs into AC with 21' cord. 20" L x 14 1/2" W x 10 1/4" D (17 lbs.)
