hygger Electric Aquarium Cleaner, Rechargeable Cleaning Tools Kit with 6 Replaceable Clean Spin Brush Heads Cordless Use 2 Speeds Adjustable Handle for Tank Corner/Wall/Filter Media/Stone Decoration

Excellent product. i still haven't learned all its uses, but it made my aquarium look normal after weeks of buildup following the death of my plecostomus. Might be useful for cleaning other glass surfaces.

Works well on 240 gallon 8 ft aquariumone brush arrived with bent bristlesDoes not replace needing a blade to remove hard algae off glass

The Hygger IPX8 Electric Aquarium Cleaning Brush has made cleaning my aquarium much easier and faster. The waterproof design allows it to be fully submerged, so I can clean inside the tank without worrying about damaging the motor. It has strong spinning power that removes algae and buildup from the glass with very little effort. I also like the interchangeable brush heads, which make it easy to clean different surfaces in the tank. Overall, it’s a very convenient and effective tool that saves time and keeps my aquarium looking spotless.

Does the job but is very noisy. Fish were nearly traumatized.

I considered 5 stars but the units is a bit harder to use than I expected and a couple of the cleaning heads have little value. The motor and drive do have a lot of power but I would like to be able to attach the upper portion of the handle shaft into the motor unit. But it can do the job and that is the most important thing.
