This is an Ultenic D10 robot vacuum cleaner, a slim, round, self-driving vacuum designed to keep floors tidy with minimal effort. It uses a raised navigation sensor on top for smart route planning, and has simple top controls for quick start and returning to the dock. Underneath, it has a main roller brush for lifting dust and pet hair, a spinning side brush to sweep edges and corners, and drop sensors to help prevent it going over steps. Rated power is 40W and working voltage is 14.4V
