<p>Disclosed is a ground cleaning device, comprising a dust collecting chamber (3), a suction motor (4) and a dust scrapping strip mechanism; the ground cleaning device is provided with a dust suction inlet (120) at the bottom; a rolling brush is accommodated in the dust suction inlet (120); the dust suction inlet (120) communicates with the dust collecting chamber (3) via an air channel (11), and is provided with a dust scrapping strip mechanism at the back side; the dust scrapping strip mechanism is connected to the bottom of the ground cleaning device via a rotary shaft (24), and is also connected to a return element. When the ground cleaning device travels on the ground and encounters higher friction, the dust scrapping strip can perform rotational or telescopic motion to reduce the friction, thus improving the traveling capability of the ground cleaning device.</p> |
