A floor tool for a vacuum cleaner comprises a cleaner head having a main body 4, a sole plate 5 with an inlet (15, fig 3) through which dirt-laden fluid enters the cleaner head, an outlet duct 6 fluidly connected to the inlet (15, fig 3) through which the dirt-laden fluid exits the cleaner head, two inflatable supports 7, 8 housed between and connected to the main body 4 and the sole plate 5, and an actuator assembly 9 for regulating the size of the inflatable supports 7, 8. The sole plate 5 is movable relative to the main body 4 in a vertical direction between a first position and a second position, movement of the sole plate 5 is controlled by the size of the inflatable supports 7, 8 and the inflatable supports are arranged either side of the inlet (15, fig 3). The actuator assembly 9 preferably comprises a single valve (25, fig 6). |
