1. A nasal irrigation device for communicating an irrigant to a device user comprising:
a reservoir assembly which includes an upper reservoir and a lower reservoir;
a lid for pouring irrigant into the upper reservoir, wherein the upper reservoir is disposed about the lid; and
a mechanics module that comprises:
a vacuum source for forming a relative vacuum in the lower reservoir;
a fluid passageway for communicating the irrigant from the upper reservoir to the lower reservoir via a nasal cavity of the device user;
a valve for releasing the irrigant from the upper reservoir to the fluid passageway; and
a switch for controlling the valve and the vacuum source.
