To provide a self-propelled floor wax peeling apparatus with high operability for easily moving up and down a ground polishing part provided on a front side of a vehicle body and for easily switching between a grounding state and a waiting or moving state.

A transmission part C is provided to transmit between a motor M and a ground polishing part 2 by an endless body 47 and rotate the ground polishing part 2 to be grounded to a floor 3 so as to peel and remove the wax on the floor 3, and is provided between the motor M and the ground polishing part 2 to include a motor base 43, the motor M, a support member 44, and the ground polishing part 2. The transmission part C swings around a swing shaft 29, so that the self-propelled wax peeling apparatus can switch between a waiting state A where the ground polishing part 2 is lifted upward and a grounding state B where the ground polishing part 2 is grounded to the floor.
