Cleaning appliance

A cleaning tool for a dental cleaning appliance - preferably a toothbrush comprising a cleaning head 160 - comprises a nozzle 36 for delivering a burst of working fluid to the teeth of a user, a fluid reservoir 162 having a fluid inlet 164 through which the fluid reservoir 162 may be replenished, and a cap 166 for selectively sealing the reservoirs fluid inlet 164. The cap 166 further comprises a fluid port 182 and is moveable relative to the fluid reservoir 162 between a first position in which the fluid inlet 164 is exposed by the fluid port 182 to enable the fluid reservoir 164 to be replenished, and a second position in which the fluid inlet 164 is occluded by the cap 166. The delivery of a burst/jet of working fluid, preferably water, to the teeth of a user allows for the interproximal cleaning of the gaps between teeth.
