1. Easy Loading, Unloading, and Cleaning: The water tank of the vacuum cleaner is typically equipped with a quickrelease mechanism, making it easy to assemble and disassemble, simplifying the process of filling and emptying water. The internal structure is simple, with some parts being integrally molded, making it easy to clean and keeping the water tank hygienic. 2. Filtering Dust and Contaminants: In vacuum cleaners with water filtration, the water tank serves as a key filtering component. When dust and dirt are sucked into the water tank, they are wetted, dissolved, and precipitated by the water, effectively preventing secondary contamination caused by fine dust overflow. 3. Even Water Dispersion: Inside, there is a special structure or device that ensures water is distributed evenly, allowing all parts of the mop to be thoroughly moistened. This results in more uniform wiping, avoiding situations where some areas are dry while others are wet, thereby improving cleaning quality. 4. Protecting Floor Materials: The water tank drains evenly, keeping the mop moderately damp. This effectively removes floor stains while preventing moisturesensitive materials like wooden floors from being damaged by excessive water, thus protecting the flooring.
