【Four Cleaning Modes】 Most of the cleaning modes of robotic vacuum cleaners on the market involve random walking. In comparison, the Lefant cleaner robot has four cleaning modes: automatic, planning, fixed point, and edge. The planning the cleanup trilogy can carefully clean every corner of your home, making cleaning so easy! 【Brushless Nozzle Design】 Traditional robotic vacuums with rotating brush heads are tedious to clean due to tangled hairs on the rotating brush. The M210 is equipped with an advanced 2200 Pa brushless nozzle and two side brushes with powerful suction power to draw hair, debris and dust directly into the large capacity (500ml) dust collection bucket. This is very convenient and effective. Two layers of filtration prevent secondary contamination. 【Small body design】 The one-piece body design has a diameter of only 28cm and is 7.8cm thick, making it ideal for use in narrow spaces found in beds, sofas, and corners to avoid snagging. It provides high coverage and has a very low failure rate. The robot vacuum also boasts a long battery life, running for up to 120 minutes before automatically returning to the charging station at the end of the cleaning cycle or when the battery is low. 【FreeMove 3.0 Technology】It has a built-in 6D anti-collision infrared sensor that detects the surrounding environment through 720-degree omnidirectional detection, instead of mechanical collision. While reducing the size of the fuselage, it can more easily avoid obstacles and reduce failures caused by wear, deformation, dust accumulation, etc. It is able to detect stairs to prevent falls and easily climb carpets. 【Large Bin】The M210 features a 500ml bin that only needs to be cleaned every 5 to 7 days. In comparison to most other 300ml bins, it can hold more waste and decrease the frequency of bin cleaning.
