A filter cleaning device having a base with a central aperture. A threaded male and female vertical post is coupled together as a single combination post and is mechanically fastened to the base within the central aperture. A filter is insertably retained on the combination post and adjusted vertically by a mechanical coupler which releasably secures the filter for effective cleaning. The filter rests on a rotatable disc which is insertably attached to the combination base and post assembly. The disc has a channel having a number of bearings to produce a rotating interface the filter and the base. The base is a hollow reservoir and has a channel for inserting weighting material such as water or sand to reduce toppling from moment induced forces. The volume of the base is maximized by a minimizing the depth by which the male post in particular is disposed within the base a predetermined distance. A channel cap is fastened to the channel to prevent spillage of the weighting material. The filter cleaning device is light weight and simple to use.
