Abstract
Abstract A portable leaf cleaner is disclosed into which plant leaves to be cleaned or otherwise treated are introduced between rolls which apply a cleaning fluid to the leaves. Means are provided for controlling the flow of fluid to the rolls. One of the rolls is driven by a reversing motor while the other is frictionally driven by the first roll. The other roll is resiliently urged against the first roll, so as to be movable relatively to the first roll, to thereby prevent breakage or damage to the leaves as they pass between the rolls. The reversing motor is energized by a battery or cell, and the device is supported by a handle which is adapted to be grasped in one hand and has means associated therewith for controlling an electrical circuit which energizes the motor.
