Dreame H12 Dual 3-in-1 Wet & Dry Vacuum Cleaner is a vacuum cleaner suited to homes wanting one machine for washed hard floors and handheld vacuuming. Its verified specification includes Wet-and-dry floor washing plus handheld vacuum modes, Up to 35 minutes wet/dry and up to 60 minutes handheld, and 900ml clean-water tank. It also provides Edge-to-edge floor cleaning, giving a clear picture of the model’s main day-to-day capabilities. On suitable hard floors, that combination supports one-pass wet-and-dry cleaning without switching between separate floor-washing tools. Ownership is further shaped by Automatic dirt detection in floor-washing use together with Self-cleaning roller with hot-air drying. It is especially relevant for everyday edge cleaning around skirting and room boundaries and owners who value a self-cleaning floor roller. H12 Dual differs from the floor-washer-only H12 Pro by converting into a handheld vacuum, while retaining a dedicated wet-and-dry floor-cleaning head. Overall, the appeal is the combination of these confirmed model-specific functions rather than features assumed from other Dreame products in the same family.
