ABSTRACT:
A sprayer, which in one embodiment, is a hand held ergonomic sprayer is disclosed herein. The sprayer may include: a housing through which water flows; a handle for gripping by a user, which is joined to the housing; at least one spray nozzle operatively connected to the housing; and, a connection for a hose, the connection being joined to the housing. In one non-limiting embodiment, when the sprayer has one end of a water-filled hose connected thereto, the combination of the sprayer and suspended portion of the hose has a combined center of gravity that passes through the axis of the sprayer handle. The sprayers described herein may also have other features, and provide other benefits that do not require the sprayers to have an ergonomic design.
