Cleaning vacuuming and mopping tools is a major part of everyday household floor cleaning, and conventional vacuum cleaners are not fully automated at every step. Too many cleaning tools take up space in the home, causing storage problems for users. Therefore, in order to improve the cleaning efficiency of the equipment and meet user demand for fully automated floor cleaning, Dreame designed this wet-dry vacuum, which can complete "vacuuming + mopping + self-cleaning" in one product. Compared with competing products, the Dreame H12 Dual has a mopping mode, suction mode, and mite-removal mode. Freely switch between modes for a comprehensive cleaning experience that extends from the floors to the whole house. The new dual-facing corner brush roller design provides improved edge cleaning to pick up dirt in hard-to-clean places. The one-touch self-cleaning is simple and convenient, avoiding dirty hands, and eliminating the tedious task of manual disassembly and cleaning. Hot air drying is provided after sterilization and cleaning to thoroughly clean both the roller brush and tube and prevent unwanted odors. Smart dirt sensing and variable-frequency suction power adjustment automatically adjust to the most suitable suction power based on the level of dirt on the floor in real time, ensuring optimal cleaning results and saving energy. It is built with a backpack design, placing the clean water tank at the back, and the wastewater tank at the front. The overall shape has a very high-tech feel, and the exterior design of polygons and blocks imbues the product with a sense of power, while highlighting the product's strong performance. This allows users to have a convenient and efficient cleaning experience while also feeling the value of brand innovation.
