Meet the SnowBot Pro from Left Hand Robotics: a snow clearing robot that can clear 12 hours of human work in less than 1.5 hours. The robot comes with a 4′ wide rotating brush to get the job done. It uses GPS to follow a pre-determined path and array of sensors to avoid obstacles.
These robots can clear walkways up to 8 times faster and reduce the number of workers required on harsh snowy days.
