Magnetic rotating cleaning apparatuses for cleaning of aquarium walls are shown and described. Each of the cleaning apparatuses includes a first magnetic assembly disposed on an outer surface of the aquarium wall, the first magnetic assembly having an anti-friction pad fixedly attached to a first end of the first magnetic assembly, and a second magnetic assembly disposed on an inner surface of the aquarium wall, the second magnetic assembly magnetically paired to the first magnetic assembly, the second magnetic assembly having a scouring pad fixedly attached to a surface of the second magnetic assembly, the scouring pad making surface-to-surface contact with the inner surface of the aquarium wall. Rotation of a rotation mechanism drives rotation of the first magnetic assembly, rotation of the first magnetic assembly causing synchronistic rotation of the second magnetic assembly. In some examples, the scouring pad has at least one opening configured to reduce surface-to-surface contact between the scouring pad and the inner surface of the aquarium wall, and to collect debris from the inner surface of the aquarium wall and reduce friction during rotation.
