Beach cleaning machines work by collecting the debris and moving them to a disposal area. This can be done manually or by using special machines. For example, in some beaches, workers use a stiff brush to scrub the sand and remove the debris. However, this method can be quite time consuming, which is why machines like the beach vacuum robot were invented. These machines use a suction system to suck up sand and dirt. They can even be fitted with a UV filter which sanitizes the debris.
