Twopart magnetic aquarium glass cleaner with an external magnet and an internal floating brush. Move the outside magnet to guide the inner brush along the glass; the floating brush cleans without sinking. Benefits and features Efficient cleaning: external magnet drives the inner brush to scrub away algae and residue along the glass. Hands operation: simply slide the external magnet to clean hard surfaces without touching the water. Inner brush floats: easy retrieval if it separates from the magnet, reducing downtime. Strong magnetic pull: designed for stable contact across typical glass tanks. Gentle on glass: soft bristles and safe plastics protect tank surfaces. Durable, low maintenance: ABS housing, corrosionresistant magnets, washable bristles. Compact and lightweight: easy to handle, store, and maneuver in tight spaces. Compatibility and use Works with most standard glass aquariums; suitable for freshwater and saltwater setups. Practical scenarios: Clean the front panel of a home freshwater or reef tank without getting hands wet. Reach around filter outlets and corners that are difficult to access with a sponge cleaner. Maintain tall or wide tanks where reaching the glass is challenging. This design emphasizes function, reliability, and ease of use for regular tank maintenance.
