【Triangular Design】The triangular shape reduces frictional resistance, allowing for flexible rotation and easier handling. It helps clean narrow windows and hard-to-reach areas without leaving streaks or missed spots, providing a more thorough clean. 【High-Quality Materials】Constructed from durable plastic materials, this cleaner is resistant to wear and corrosion. It features strong magnetic force for reliable performance while remaining safe and non-toxic. 【Double-Sided Magnetic Design】The powerful double-sided magnetic system enables effective cleaning of glass surfaces from a distance, allowing you to clean high windows without reaching outside. 【High Efficiency】Equipped with double-sided cleaning brushes, it doubles cleaning efficiency and reduces effort. The inner and outer parts move in sync thanks to strong magnetic attraction. 【Wide Compatibility】Suitable for single-pane glass windows between 3-8mm thick. Ideal for use on sliding doors, windows, car windows, shower doors, mirrors, and other smooth glass surfaces.
