Dreame L40s Ultra AE
The Dreame L40s Ultra AE is a high-performance robotic vacuum and mop designed for thorough cleaning on multiple floor types. It delivers powerful 19,000 Pa suction combined with dual brush systems—a liftable rubber main brush and a TriCut hair-cutting brush—ideal for homes with pets and children. The vacuum features advanced AI-enhanced obstacle avoidance using RGB cameras and 3D structured light, enabling it to navigate cluttered environments efficiently. It can climb thresholds up to 40 mm (1.57 inches) and uses hot water mop washing at around 75°C for deep cleaning. The self-emptying dock automatically disposes of dust and washes mop pads, minimizing user maintenance. With multi-spectral dirt detection and smart mapping, it offers scheduled, spot, edge, and auto cleaning modes for comprehensive floor care.
