With the dual-sided magnetic design, the hygger aquarium cleaner brush makes it a breeze to wipe the outside while the tank’s inside is simultaneously cleaned, it is easy to move up and down to clean the tank walls. You can effortlessly follow the outside handle to make cleaning incredibly easy and enjoyable while saving you time and effort. The grip has a nice touch and won’t slip on wet hands. The magnetic brush will float to the top when you release it, and the powerful magnetic force will guide it to reconnect with the outside magnet.
