Designed to separate clean and dirty water, preventing secondary pollution, it uses independent dual compartments for clean and dirty water, keeping them completely separate so there’s no backflow or mixing. When cleaning, the water is clean, the floor smells fresh, and it effectively avoids stains and bacteria, making cleaning more thorough. Made from high-transparency, wear-resistant material, the durable and easy-to-see fully transparent tank with precise markings lets you clearly check remaining water and the cloudiness of dirty water, keeping track of cleanliness in real time. The tank material is strong, resistant to bumps and ageing, so it won't easily deform or yellow with long-term use, making it more durable. Multiple water flow settings, compatible with various floor types, allow you to adjust the water output according to tiles, wooden floors and other surfaces. The water flows evenly and finely without pooling, mopping dries quickly without leaving watermarks, effectively protecting all kinds of floor materials, suitable for various home scenarios. One-touch quick-release design makes cleaning and assembling hassle-free. Side clips can be released with one touch, allowing you to assemble or disassemble with one hand, no bending or straining needed. The box has no complex corners and can be rinsed directly with water, no need to take apart small parts, making daily cleaning simple and convenient. Supports automatic cleaning, with a water circulation system that leaves no residual water and allows the whole machine to self-clean, automatically circulating clean water to rinse the brushes and internal pipes. The tank is designed for smooth water flow, reaching every corner to wash the walls, preventing the build-up of dirt and scale, keeping the water system clean and clear for a long time.
