Strong MagneticThis fish tank cleaner helps clean glass by magnetizing from an outside brush to the inside brush, quickly and easily cleans away algae. You can use it to clean the windows and walls as well. Premium QualityThe scrubber side is made of fabric with tiny hooks that scrape off the algae without damaging the glass. The additional algae scraper has a good effect on some dirty stains which are difficult to clean. Comfortable& Non-slip HandgripThe design of the handle considers ergonomics, so it is very easy and comfortable to use. Floating& StorageBecause its specific gravity is light, the cleaner will float on the water automatically. When you don't want to use it, you can pick it up directly from the water. When the cleaning is finished, there is no need to take it out, just adsorb it on the glass. Note&WarrantyPlease be careful not to pinch your fingers. Because the magnetic force is strong, it is necessary to rotate the two brushes 90 degrees and then separate them.
