The Dreame L50s Pro Ultra is a mid-range robot vacuum that combines features usually found in more expensive models. It offers a powerful suction of 30,000 Pa, an upgrade from the previous model's 19,500 Pa, and a high-temperature mopping function that heats water to 100 °C, compared to 75 °C on earlier versions. The robot includes several advanced features, such as an extendable side brush, an extendable mop, AI navigation, a detergent cartridge, and the ability to navigate over obstacles. Its design is based on the L10s Ultra model, featuring a vertical charging station that saves space in narrow areas. The station includes two water tanks, a dust bag, a detergent reservoir, and a fixed washing board with 20 spray nozzles to clean the mop. The robot has a fixed LiDAR dome with a metallic finish, an AI camera, a structured light sensor, and an auxiliary LED for obstacle detection. It also has a double hybrid brush roll made of rubber and nylon, which is ideal for cleaning carpets and tile joints. Two rotating mop pads allow for more thorough cleaning, with the right pad able to move aside for better access along baseboards. The articulated side brush can extend to collect dirt under furniture and in corners. The robot is available in black or white and is controlled via a dedicated app, which allows users to map their home, customize cleaning routines, and set up restricted areas. The app offers multiple cleaning modes, including suction-only, mopping, and combined suction and mopping. Users can adjust suction power, mop humidity, and how often the mop is washed. The CleanGenius mode automatically manages these settings. The app also includes a pet owner mode, allowing the robot to focus on areas around pets' bowls or litter boxes and even take photos during cleaning. The robot is compatible with Alexa and Google Home and has its own voice assistant for control. In performance, the Dreame L50s Pro Ultra handles moderate dirt well, often cleaning in a single pass, though stubborn stains may require multiple attempts. It can detect dirt clumps and adjust suction power accordingly. The articulated side brush helps with baseboards and furniture legs, but may struggle with very tight corners. On carpets, the robot uses strong suction and a cross-pass technique for better cleaning. The high-temperature mopping function uses two rotating mops and a detergent mix to improve cleaning effectiveness. However, the robot sometimes takes inefficient paths and may bump into objects, though it adjusts its route in real time. The robot's station is designed for minimal maintenance, with features like hot water washing and automatic mop drying. Daily tasks include emptying and refilling water tanks, which can cover about 150 square meters. The detergent reservoir lasts months with one refill, and the app includes an automatic cleaning mode for the washing board. The Dreame L50s Pro Ultra is currently available at a promotional price of 599 euros at several retailers, compared to its regular price of 750 euros.
