The present invention discloses a surface cleaning device capable of peeling off entangled objects, comprising a floor brush equipped with a roller brush, wherein the floor brush is provided with a comb tooth part and a scraping part, wherein the comb tooth part and the scraping part are both in contact with the roller brush, wherein the comb tooth part comprises a first end and a second end located between the scraping part and the first end, wherein the deformation amount of the scraping part in contact with the roller brush is greater than that of the first end and the second end, and the deformation amount of the second end in contact with the roller brush is less than that of the first end. By adopting the technical solution, pressure release can be formed at the second end, so that the entangled objects passing over the first end release pressure at the second end and are peeled off by the scraping part.
