A powered irrigator for use in rinsing nasal cavities including a main body having a handle and fluid reservoir detachably coupled to one another, an outlet nozzle extending from a top end of the handle, a pump mechanism operably coupled to a power source, and a switch operably coupled to the power source for turning the pump mechanism on and off, and when the switch turns on the pump mechanism, fluid flows from the fluid reservoir into a first fluid coupling between the reservoir and the pump mechanism and into a second fluid coupling between the pump mechanism to the outlet nozzle. The reservoir includes a generally centrically body defining a cavity and at least two tabs connected to the cylindrical body and extending inwards therefrom. The at least two tabs operably connect the reservoir to the handle portion to releasably secure the reservoir to the handle portion.
