The present disclosure is directed to magnetic rotating cleaning apparatuses for cleaning of an aquarium wall. A magnetic rotating cleaning apparatus includes a first magnetic assembly and a second magnetic assembly magnetically paired to the first magnetic assembly. An aquarium wall is disposed between the first magnetic assembly and the second magnetic assembly such that an anti-friction pad of the first magnetic assembly contacts the outer surface of the aquarium wall and a scouring pad of the second magnetic assembly contacts the inner surface of the aquarium wall. A coupling mechanism selectively couples a rotation mechanism to the first magnetic assembly. The rotation mechanism is configured to drive rotation of the coupling mechanism, while rotation of the coupling mechanism drives rotation of the first magnetic assembly and rotation of the first magnetic assembly causes synchronistic rotation of the second magnetic assembly. In some examples, the magnetic rotating cleaning apparatus includes specific features to maximize magnetic pairing between the first magnetic assembly and the second magnetic assembly. In other examples, the magnetic rotating cleaning apparatus includes specific features to minimize friction between the anti-friction pad and the aquarium wall during operation.
