An upright-type electric vacuum cleaner including a vacuum cleaner main body with at least a dust collector and an exhaust outlet, and a suction body provided at a lower front of the vacuum main body. The dust collector is disposed on a rearward side of the vacuum cleaner main body and wherein the exhaust outlet is disposed on a front surface side of the dust collector. The area of the exhaust outlet can be made large without being interfered by the dust collector.

Upright-type electric vacuum cleaner with detachable dust collector

A floor suction tool for electric vacuum cleaners includes a suction opening formed on a bottom face of a main body casing, a cover defining a front wall of the main body casing, and an abutting member projecting from a front face of the cover and functioning as a bumper between a front face of the main body casing and a wall. The cover is rotatably supported on a rotation axis formed horizontally in a direction of width of the front wall of the main body casing, the cover rotates upward to open the front face of the main body casing when a front-to-back force acts on the abutting member, and the cover rotates downward to close the front face of the main body casing when the front-to-back force ceases.

Floor suction tool for electric vacuum cleaners

Pressurized filtered exhaust air from a motorized fan in a vacuum cleaner body passes on an exhaust path to a floor suction tool. The exhaust air is directed by the floor suction tool generally parallel to the surface to be cleaned to agitate dust and thus to improve cleaning performance. An electric motor in the floor suction tool drives a rotation brush. The exhaust air is also directed toward the rotation brush in the floor suction tool in a direction to add rotation force to the rotation brush. Feeder lines to the electric motor pass through the exhaust path so that the feeder lines are exposed only to filtered air. Passing the feeder lines through the exhaust path avoids the necessity to make special provision for the feeder lines. The exhaust path passes along a hose, and may optionally pass along one or more extension pipes on its way to the floor suction tool.
