A hand-held rotary cleaning tool includes a housing that encloses an electric motor and a gear set that connects the motor to an output shaft. The rotary cleaning tool includes at least one cleaning accessory that is detachably connected to the output shaft, and a flexible splash guard. The splash guard surrounds the output shaft and cleaning accessory so as to prevent liquid splash during tool use. The splash guard includes a reinforcing ring that is formed of a material that is less flexible than the material used to form the splash guard body. The reinforcing ring prevents the splash guard from excessive deformation, whereby interference of the splash guard with the cleaning accessory or the output shaft is minimized or avoided. The reinforcing ring may also include other features which enhance the cleaning function of the rotary cleaning tool.
