Tapo RV20 Mop is the thinnest laser-guided robot vacuum on the market. It doesn’t have a raised laser sensor module like other laser-guided vacuums, allowing it access under lower cabinets and beds to clean harder-to-reach areas. The smooth surface is even ideal for pets to perch on and patrol the house. RV20 Mop also supports accurate navigation and mapping, room-based cleaning, no-go zones, and other advanced functions. More than 100 built-in voice operation prompts increase the convenience of use, which can help users who don’t have smartphones to get started easily.
