Meet the Dronyx Solarino Robotic Cleaner: a beach cleaning machine that can move on wet and dry sand to remove junk. It is powered by sunlight and batteries. The Solarino Beach Cleaner has a durable frame and tracks. It doesn’t make a whole lot of noise and can cover 3000 sqm pr hour.
This machine has a stainless steel and aluminum frame. It runs for up to 3 hours on battery. The bad news? Something like this doesn’t come cheap.
