Abstract: Self-travelling vacuum cleaner (10) has body (20) having suction port (101), drive unit (30), and an electric fan. Since suction port (101) is disposed in a maximum width part of body (20) closer than drive unit (30), self-travelling vacuum cleaner (10) can suck a trash on a corner in a target region to be cleaned easily and can move from the corner to another area quickly.

Abstract: The present invention provides a technology, which is capable of easily switching between the vacuum function and the blower function of the vacuum cleaner with a simple configuration, and is also capable of effectively utilizing the blower function even in the various situations. Typical air suction/injection device is configured that the interior of the main unit constitutes a main passage of air, and the interior of an injection passage section provided in the main body constitutes a sub-passage. Once a suctioned airstream is created in the main passage, a power fan inside of a suction chamber is rotated, and in conjunction with such a rotation, an injection fan is rotated so that an injecting airstream is created in the sub-passage. In such case, a passage switching section composed of a valve member provided in the location of joining the main passage and the sub-passage is switched to easily switch between a creation of an injecting airstream and a creation of a suctioned airstream.

Abstract: A floor care apparatus includes a housing having a nozzle assembly and a canister assembly. Both a suction generator and a dirt collection vessel are carried on the housing. An agitator cavity is provided on the nozzle assembly. A rotary agitator is provided in the agitator cavity. The rotary agitator includes an internal space. An agitator drive system is provided in the internal space of the rotary agitator. The agitator drive system includes first and second drive motors that simultaneously drive the agitator.

Abstract: Provided are rotary brush unit which is disposed inside suction port portion and in which two rotary shaft bodies each having brush are disposed in series and driving motor which separately rotates each of the rotary shaft bodies. With such a configuration, since it is possible to change a self-propelling direction of the suction port portion to the left and right direction in addition to the forward direction, it is possible to remarkably reduce the effort involved in an operation of changing the direction of the suction port portion.

Abstract: A room air cleaner for use in automobiles is disclosed. The room air cleaner comprises: a housing and a cover which form a box-like body, inlet and outlet openings formed in opposite sides of the box-like body, and a discharge device, a filter, and a motor-mounted fan which are arranged in this order in said box-like body in a substantially horizontal direction starting from the side in which the inlet openings are formed. Thus, the room air cleaner achieves a low profile design of the product and thereby assures the driver of an enlarged rear view field, and is capable of operating more quietly without affecting its air suction capacity and dust collecting performance despite the low profile design.
