This electric power head attaches to your Pullman-Holt Model 390 or 390ASB Canister Vacuum to provide extra power for superior vacuuming results. The heavy-duty double steel brush roller provides a 13" cleaning path, plus the agitation needed to get carpets deep-down clean. A power cord connects directly to the electric outlet on your Pullman-Holt vacuum. Simply attach the tool, plug it in, and you're ready to get to work—no special tools needed. It draws 1.5 amps and weighs only 5 lbs. Offering automatic height adjustment, you can use it on all types of carpet pile and thicknesses. The low-profile design makes it easy to clean under furniture, chairs, and couches and the non-marring bumper helps to protect furniture and baseboards from bumps and scuff marks. Built-in bright headlights provide excellent visibility, even in dark areas, such as poorly lit closets and corners. A motor protection system prevents damage to the unit due to a blocked brush roll, so there's minimal risk of overheating and breakdowns and a see-through brush window lets you get a clear view of any obstruction in the brush roll, so you can easily remove it.
