Key benefits Efficient, safe cleaning: Strong magnets adapt to variable glass thicknesses for reliable bilateral adhesion across aquariums, letting you clean both inside and outside surfaces without slipping or dropping. Comfortable, controlled handling: Palm-shaped design with a non-slip texture provides a steady, ergonomic grip for smooth, precise movements and reduced hand fatigue. Fast repositioning and retrieval: An internal suspended "brush assembly" causes the tool to float and automatically return to the water surface after detachment, making it easy to reposition or remove during use. Glass-friendly results: Wear-resistant inner bristles combined with an outer fabric layer remove algae and residue gently, protecting glass from scratches while delivering consistent cleaning performance. Features and how they solve problems Magnetic power suitable for variable glass thicknesses: Prevents the tool from losing contact on different tank walls, so you can clean thick panes and thinner glass without swapping tools. Safe bilateral adhesion in all aquariums: Secure contact on both sides reduces the risk of accidental drops or damage to décor and equipment. Non-slip, palm-adapted grip: Keeps control during vertical and horizontal strokes, improving accuracy on corners and large panes. Effortless floating mechanism: The suspended internal brush assembly ensures the cleaning head rises to the surface when released, speeding up repositioning and retrieval during maintenance. Two-layer cleaning surface: Inner bristles break up stubborn residue while outer fabric polishes and collects loosened material, minimizing streaks and recontamination. Compatibility, materials, and performance Compatible with a wide range of aquarium glass thicknesses (magnet adjusts to variations). Cleaning surfaces: wear-resistant bristles (inner) and protective outer fabric. Construction designed for repeated use with reliable adhesion, smooth motion, and safe contact with glass. Practical use scenarios Routine maintenance: Remove daily film and light algae from freshwater or saltwater tanks without removing décor or disturbing fish. Deep spot cleaning: Target stubborn green algae along corners, near filters, and behind ornaments using controlled strokes and the bristle edge. Large-panel cleaning: Clean big panes and tall aquariums confidently; the magnetic adhesion and comfortable grip make long strokes easier and safer. What to expect in regular use Steady magnetic hold across different glass thicknesses. Comfortable, slip-resistant handling for extended cleaning sessions. Quick recovery of the cleaning head after detachment, thanks to the floating brush assembly. Gentle but effective removal of residue without scratching the glass. Note: Product functions and components described are consistent with the original design: magnetic adhesion for variable glass thicknesses, non-slip palm-adapted grip, internal suspended "brush assembly" that floats after detachment, and a two-layer cleaning surface (wear-resistant inner bristles and outer fabric).
