The present invention relates to an airflow management system, particularly for a lawn mower, especially a robotic lawn mower. We describe a battery-operated robotic lawn mower with an active airflow management system, said active airflow management system comprising: at least one first air vent (303) positioned on an underside of said mower at least one second air vent (302) an internal housing surrounding a motor (102) a fan (201) and at least one cooling air channel located within said housing and around said motor. An air flow path is defined between the first (303) and the second (302) vents and said at least one second vent (302) has a lower air flow capacity than an air flow capacity of said at least one cooling air channel, such that in operation, a greater volume of air is drawn through the first vent (303) than the second.
