The air is sucked into the fan chamber 245 through the port 211 b and the flow path 213, and then flows into the fan chamber 12 of the cleaning tool 10 through the flow path chamber 253, the connecting pipe 257, and the hose 261 to rotate the fan 50.
[0090]
Therefore, by opening the valve 241a, air can be sucked from a path that does not pass through the dust collection chamber 214, and therefore the supply required for rotating the fan 50 even when the dust collection bag 220 is clogged. An airflow can be reliably ensured.
[0091]
Then, the cleaning tool 10 is held in the hand with the rotary tube 14 while the fan 50 is rotated, and the bathtub or the like is cleaned in the same manner as described above.
[0092]
In this cleaner 200, a highly elastic hose 261 for sending air from the fan chamber 245 to the suction port body 270 is detachable from the pipe 204 a of the connection pipe 204, and the hose 261 is attached to the cleaning tool 10. Since the connection is made, there is an advantage that the hose 261 can be shared or a dedicated air supply hose is not required.
