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

Works well on 240 gallon 8 ft aquarium one brush arrived with bent bristles Does not replace needing a blade to remove hard algae off glass

I've tried all the sliding magnets and hand held brushes, nothing compares to this product. When you do a water exchange is the best time to use this since it can get a little messy with a full tank of water (I have a 55 gallon). There are different attachments for different situations, I love the scoring pad, removes every bit of the film build up or any algae on the glass. Comes with 2 speed motor (slower is better) and extension handles. Best thing money can buy for your aquarium. PS< Their customer service is the best by far. I have their aquarium light, air pump. heater ,this cleaner and all are top quality and made better then many other products for your tank.

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

Had some issues with the product. Contacted company and they resolved all my issues. Great product to help clean my tank.

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.
