20220346618 · 2022-11-03 ·

A floor cleaner includes an electrically powered component and a switch. The switch includes a button including an actuator surface. A fluid channel is formed by a fluid collection surface disposed below the button and an outer channel wall extending upwardly from the fluid collection surface, the fluid channel having a fluid outlet. A projection of the button is received in an inner button aperture formed by an inner wall extending from the fluid collection surface forming a bushing around the projection. The inner wall inhibits flow of fluid from the fluid channel through the inner button aperture. The outer channel wall surrounds the aperture wall such that fluid entering the body between the perimeter of the button actuator surface and the aperture wall is collected by the fluid channel and directed to the fluid outlet.
