A magnetic glass cleaner for aquariums uses an external magnet to drive an inner floating brush along the glass. As you move the outside magnet, the inside brush follows to scrub the glass, and the floating design keeps the inner brush from sinking in the tank. The system provides strong magnetic force for effective cleaning through the glass. Benefits - Effective glass cleaning with minimal reach into the tank - Inner brush remains afloat, reducing risk of losing or sinking the cleaning element - Strong magnetic force delivers reliable performance through standard aquarium glass - Simple, intuitive operation by moving the outside magnet Features - External and internal magnet pairing for hands-free alignment and scrubbing action - Floating inner brush attached to the internal magnet so it does not sink - Strong magnetic attraction to scrub algae and deposits from the glass surface - Designed for use in typical glass aquariums, with straightforward operation Use scenarios - Regular maintenance: quickly clean front panel glass during routine tank care - Algae removal: target persistent algae on glass walls by guiding the outer magnet along the surface - Back panel access: reach difficult-to-access panels by moving the external magnet around the tank while the inner brush follows Specifications and compatibility - Function: magnetic glass cleaning system for aquariums - Operation: outer magnet moves to control the inner floating brush - Performance: strong magnetic force for effective cleaning through glass - Compatibility: suitable for standard aquarium glass surfaces This description preserves the product’s core function and demonstrated behavior: moving the outside magnet causes the inside magnet brush to scrub the glass, with the interior brush remaining afloat to avoid sinking, and the system delivering a strong magnetic pull for efficient cleaning.
