Water Resistance: Does rain or water hurt the mower?
Robomow® and it’s docking station have been specifically designed to remain outdoors during the mowing season. They are completely waterproof and the rain and other summer weather will not damage anything. Under normal circumstances, a unit exposed to rain will not be damaged. We would not advise putting the mower into operation during a severe storm, however should it begin raining while it is operating, there is no problem for Robomow®. Wet mulched grass tends to be sticky and build up at the mulching deck area and will need to be cleaned often if one mows in the rain. We do not recommend washing the unit with a water hose, particularly from the underside.
