Magnetic eraser assemblies for cleaning the window of an aquarium tank includes an inner cleaning assembly(10) and a hand cleaning assembly(20) sliding on the outer surface. The inner cleaning assembly(10) comprises a front cover(13), a rear cover(14), a magnet(15) and a cleaning surface(16). The hand cleaning assembly(20) comprises a bottom case(23), a handhold(24), a magnet(25) and a cleaning surface(26). At least one of the magnet(15) and the magnet(25) is a permanent magnet. The hand cleaning assembly(20) on the outer surface of the observation window glass pulls the inner cleaning assembly(10) to move by magnetic force. Especially, there is a waterproof buoyancy cavity(11) on the top or upside of the inner cleaning assembly(10), and the total density is greater than that of the liquid in the aquarium tank. |
