Therefore, the dust collection besom can automatically control dust collection in the using process without frequently operating a power switch.

The using steps of the dust-absorbing broom are as follows:

1) Taking out from the storage place;

2) Holding the upper part of the handle 200 by one hand and opening the power switch at the lower part of the handle 200 by the other hand;

3) Cleaning larger sundries on the surface of the object to be cleaned, wherein the touch switch 150 is switched off, and the exhaust fan 133 does not work;

4) After step 3, the dust collection opening 100c faces and pushes against the surface of the object to be cleaned to push or pull the dust collection broom, the lower portion 143 of the dust collection pipe swings away from the balance position, the trigger switch 150 is turned on, and the exhaust fan 133 works;

5) Finishing cleaning and closing a power switch;

6) When the dust collection chamber 101 is observed, if the movable cover 111 is opened, the dust is cleaned.

7) If the suction amount of the vacuum cleaner is significantly weakened, the first housing 110 is opened, the filter assembly 160 is removed, and the filter device 163 is replaced.

8) When the dust collection port 100c is returned to the storage place, it does not interfere with any object.
