<p>A floor cleaning and liquid removal device comprises a hollow rotatable drum (20) whose exterior surface is covered with a liquid absorbent material (28). A pressure roller (30) is rotatably mounted against the drum to compress the liquid absorbent material as the drum rotates, to expel liquid from the material. The liquid is collected in a trough (40) from which it flows under gravity through a tube (130) to a hollow drum axle (23) and thence into the interior of the drum. The drum may be emptied by removing a cap from the end of the hollow axle and tipping the device sideways.</p> |
