Description

[0011]
[Means for Solving the Problems]
A vacuum cleaner according to the present invention comprises a vacuum cleaner body having a dust collection chamber and an electric motor chamber containing an electric blower, and a lower portion of the vacuum cleaner body, wherein the vacuum cleaner body is exhausted by exhausting air from the electric blower. The floating device includes a communicating port communicating with the motor chamber at an upper portion, a plurality of floating exhaust outlets at a lower portion, an exhaust pressure equalizing chamber for storing the exhaust, and a plurality of floating portions. A floating body provided with a floating exhaust port, and a skirt member made of a soft material having one end in contact with a floor surface around the floating body and having wear resistance or slip resistance on the outer surface thereof .

[0012]
The vacuum cleaner according to the present invention is provided with a vacuum cleaner body having a dust collection chamber and an electric motor chamber in which the electric blower is accommodated, and a lower portion of the vacuum cleaner body, the vacuum cleaner using exhaust air from the electric blower. A floating device for floating the main body from the floor surface, the floating device having a communication port communicating with the motor chamber at an upper portion, a plurality of floating exhaust outlets at a lower portion, an exhaust pressure equalizing chamber for storing the exhaust gas, A floating body provided with a plurality of floating exhaust ports, and a skirt member made of a soft material , the other end of which is detachably attached to the floating body so that one end is in contact with the floor surface .
In addition, the above-mentioned skirt member covered the floating exhaust air outlet from below.
