Floor brushes and cleaning equipment

Abstract

We provide a floor brush for vacuum cleaners that helps check whether the floor is sufficiently clean. [Solution] The floor brush 100 includes a floor brush body 120 including a storage chamber for housing a roll brush 110, a first light-emitting device 140, and a second light-emitting device 150. The floor brush body includes a storage chamber for housing cleaning members. The first and second light-emitting devices are mounted on the front and rear sides of the floor brush body, respectively. The lateral direction of the floor brush body is perpendicular to the direction in which the floor brush body moves back and forth across the surface to be cleaned. The second light-emitting device is illuminated as the floor brush body moves forward. This helps the user to confirm whether the area behind the floor brush body has been sufficiently cleaned, and if there is any remaining cleaning in the cleaned area, re-cleaning can be performed promptly.
