Thus, in the front drum brush 21, hot water or steam is sprayed from the second nozzle 2 to the floor surface to be cleaned to drop or loosen the dirt on the floor surface to be cleaned, and then the dirt is swept by the front drum brush 21 to the rear side of the front drum brush 21. This sweeping pattern provides greatly improved cleaning.

In some embodiments, referring to fig. 3, a front wiper strip 211 for wiping the front roller brush 21 is provided in the front roller brush chamber, and the front wiper strip 211 can wipe the contaminated water on the front roller brush 21 off from the front roller brush 21 and fall to the ground, so that the contaminated water can be more easily sucked into the contaminated water tank 12. The rear rolling brush chamber is provided with a rear scraping strip 221 for scraping the rear rolling brush 22, and the rear scraping strip 221 can scrape down the sewage on the rear rolling brush 22 to the ground, so that the sewage can be sucked into the sewage tank 12 more easily.

In some embodiments, referring to fig. 5, the front and

rear roll brushes

21 and 22 are driven by the same motor 33 disposed in the floor brush housing 20, so that the front and

rear roll brushes

21 and 22 operate synchronously, the internal structure of the floor brush housing 20 is simplified, and the control system of the host computer can more easily perform circuit control on one motor.

Illustratively, the first and

second pumps

30 and 31 are provided in the main housing 10 in front of the wastewater tank 12. Other locations may be provided as desired by those skilled in the art.

Further, referring to fig. 4, the first pump 30 and the second pump 31 may be disposed side by side, thereby simplifying the installation of the first pump 30 and the second pump 31 and improving the stability of the installation of the first pump 30 and the second pump 31.
