The Lefant M280 is a high-end robot vacuum that is currently available at a discounted price of 349.99 euros on Amazon, with the offer set to expire on October 5, 2026. Normally priced at 999.99 euros, this promotion represents a significant reduction in cost, making the device more accessible to consumers. The Lefant M280 Mini Robot Vacuum with Extendable Roller is designed to be compact, with a body size of 28 cm, allowing it to easily maneuver under furniture and beds. This makes it ideal for cleaning hard-to-reach areas in homes of various layouts. The robot vacuum is equipped with 20,000 Pa of suction power, which is a measure of its cleaning strength, and an extendable roller that can stretch by 50 mm to clean along walls and in corners. This feature helps ensure that even the most difficult spots are cleaned effectively. The device uses ToF + PSD navigation, a system that combines time-of-flight and photo diode sensor technologies to map and navigate spaces more accurately. Additionally, it includes a carpet detection system that adjusts its performance based on the type of flooring it encounters, ensuring optimal cleaning on different surfaces. Another key feature is the Zero Tangle system, which is designed to prevent hair and pet hair from wrapping around the roller, reducing the need for frequent manual cleaning. The robot can cover more than 95% of an area using its sensors, making it highly efficient in cleaning tasks. It also includes a reservoir for immediate floor cleaning, allowing it to clean and mop in one pass. After completing a cleaning session, the robot returns to its base to recharge, empty the dirty water, and collect clean water, ensuring it is ready for the next use with minimal human intervention.
