The present invention discloses a
surface cleaning device with good
suction force, comprising a floor
brush with a
sewage suction port, a body hinged to the floor
brush, and a
sewage suction fan, wherein the floor
brush is provided with a roller brush for cleaning the surface to be cleaned and a scraping member and a
combing member for cleaning the roller brush, wherein the scraping member and the
combing member are arranged above the
sewage suction port in sequence from top to bottom, and is characterized in that the
combing member is provided with a plurality of comb teeth, a gap is formed between two adjacent comb teeth, the comb teeth at least partially extend downward, so that the gap is at least partially located between the sewage suction port and the roller brush to form a slit effect area, when the sewage suction fan is working, the wind pressure in the slit effect area increases, and an unbalanced
airflow is generated at the sewage suction port, and entangled objects,
dirt, and dirty liquid such as hair scraped off by the comb teeth and the scraping member are smoothly sucked into the sewage suction port under the action of the larger wind pressure of the unbalanced
airflow, thereby further improving the sewage suction effect and enhancing the sewage
suction force of the
surface cleaning device.
