Claim:
A brush assembly suitable for use in a wet floor cleaning device, comprising: a brush comprising a hollow core, an inner surface of the core being compartmentalized into a number of compartments, an outer surface of the core being furnished with brush material, and the core being pierced with a number of outflow openings; a first fluid injector for injecting a fluid into the core; and a drive mechanism configured for rotating the brush around a longitudinal axis of the core, wherein, during rotation of the core, the injected fluid is collected by the compartments provided on the inner surface, and the centrifugal force associated with the rotation of the core drains the fluid from the compartments, through the outflow openings, into the brush material wherein said compartments extend along the entire length of a longitudinal axis parallel to the longitudinal axis of the brush assembly from a first end wall of the core to a second end wall of the core.
