Abstract
A floor brush for an electric cleaner, in which cleaning performance by a rotating cleaning body is improved while costs of the floor brush is suppressed. When a lower end section of a front cover (18) comes in contact with an obstruction and is rotated backward, a rear face of the front cover (18) comes into contact with a rotating brush (21) and simultaneously the lower end section approaches a floor surface (F). This causes an opening (38) to be narrower, increasing a load in a rotating cleaning body chamber (22) to reduce suction from the rotating cleaning body chamber (22) side. As a result, the volume of suction air from a suction mouth is relatively increased to increase rotational force of an air turbine (27a). As a consequence, in correspondence with an increase in a load applied to the rotating brush (21), rotational force of the rotating brush (21) can be increased without using, for example, a motor, so that sufficient cleaning performance by the rotating brush (21) can be obtained while costs of the brush are suppressed.
