Abstract
A modular auxiliary brush assembly for a vacuum cleaner includes a mounting bracket coupled to the vacuum cleaner, a spring-biased brush head, and a shaft which mounts the brush head to the mounting bracket. The spring-biased brush head is vertically adjustable to accommodate cleaning surfaces of varied heights and textures. The spring-biased brush head includes a tread which contacts a surface to be cleaned and rolls the brush head relative to the vacuum cleaner when the vacuum cleaner moves over the surface.
Claims12
A vacuum cleaner for cleaning a surface, comprising:
- a housing having a suction nozzle;
- a source of suction in fluid communication with the suction nozzle for generating a suction path through the housing;
- and
- a brush assembly provided on the housing outside the suction nozzle and configured to sweep dirt toward the suction path, the brush assembly comprising:
- a shaft attached to the housing;
- a brush head for contacting the surface to be cleaned and rotatably mounted about the shaft;
- a mounting bracket attached to the housing, wherein the shaft mounts the brush head to the mounting bracket, the mounting bracket comprising a sleeve that receives the shaft therein, such that the shaft can slide relative to the mounting bracket;
- and
- a spring biasing the brush head away from the housing;
- wherein the spring-biased brush head adjusts to accommodate variations in the height and/or texture of the surface to be cleaned as the housing is moved over the surface to be cleaned;
- and
- wherein the shaft is keyed to the sleeve to prevent rotation of the shaft relative to the sleeve.
