Our robots are absolutely safe for families with pets and young children. More than 1 million robot mowers have been sold in Europe over the past 10 years with a remarkable safety record. The robot has sensors that make it stop and turn around when bumping into any thing or person. The blades stop turning in less than one second if the robot is lifted from the ground. Also, a 3-inch barrier prevents fingers/toes from reaching the blades while operating. All that said, these are not toys so out of an abundance of caution please don't allow children to play with the mowers.
