Abstract

An oral irrigator has a removable reservoir defining a reservoir cavity, a base unit housing a motor and a pump, and a handle for directing fluid flow from the pump removably connected to the base unit and fluidly coupled to the pump by a hose. The handle has a housing defining a slot formed in an outer wall of the housing. The slot is bounded by two opposing walls spaced apart from each other and a transverse wall at a terminal interior end of the opposing walls. The outer wall of the housing is open to the slot at lateral sides of the two opposing walls and at a base end of the opposing walls opposite the transverse wall.
