Will my MR1 SE collide with my furniture? MR1 SE detects obstacles using its three front bumper sensors. However, if thin obstacles like furniture legs fall between the sersors, MR1 SE may bump into them, but its bumper protection will prevent damage. What should I do before using my MR1 SE? We recommend clearing small objects from the floor, such as power cords, socks, and toys, and rolling up the edges of high-pile carpets. Please follow the quick start guide and user manual strictly. What is the wa-rranty cover? Two years. Any questions please contact our after sales support department service_us via monga.com
