Abstract

A removable fluid pumping and filtration apparatus for a laundry treatment machine is provided. The apparatus includes a handle portion. A filter section is configured to selectively couple to an impeller of the laundry treatment machine, the filter section defining a hollow interior, a lower water opening to allow for the passage of water out of the interior space of the agitator, and an opening about the exterior circumference of the filter section into which a removable filter is selectively attachable. A handle pull locking post is provided within the hollow interior of the apparatus, including a handle pull portion at a top end for gripping against the handle portion and at least one pin at a bottom end configured to selectively lock the apparatus into the base.
