Letting Robomow's RM 400 mower trim the lawn for you. This robotic lawn mower is recommended for small lawns up to 2700 square feet. It comes with a base station for automated storage, charging and easy mower scheduling. You can schedule this mower to run day or night without bothering your neighbors: these machines will run at a noise level as low as 65 decibels when in eco-mode. To give a comparison, this is the same amount of noise generated by a normal conversation.
