Abstract

A sponge mop includes a post extending through a top of a frame and the frame has two extensions on each of which a roller is connected. A sponge is located between the two rollers. A lever handle is pivotally connected to the post and a link is fixedly connected between the lever handle and the ridge. A tank is connected to the post and receives cleaning detergent therein. An outlet extends from a lower end of the tank and is engaged with the hole in the frame. A seal member is removably engaged with the outlet and a control assembly is received in the tank. A lower end of the control assembly is connected to the seal member and an operation handle on a top of the control assembly is engaged with the top hole so that when rotating the operation handle, the detergent flows to the sponge.
