The  350 MECHANICALS were designed to clean carpets, perform well on most hard floors, and have superb pet hair removal! They have a convenient instant-use cleaning wand and suction hose with an eight-foot reach and three on-board tools. The four-level manual height adjustment can be conveniently changed with the aid of the cleaning wand. Plus, the machine turns off automatically and gives user notification when a brush roller obstruction occurs, which protects the belts and carpets from damage. There is also user notification when a full bag or clog occurs. Additional features include excellent filtration, a giant 1.4-gallon bag, 39-foot cord, protective rubber-coated wheels, a low 5 ½-inch horizontal cleaning profile that fits under beds and furniture, and tool-free brush strip removal for bristle cleaning or replacement.
