There are different types of technology used in road sweeping equipment. The first being the mechanical broom sweeper. It works similar to cleaning pavement with dust receptacle and a broom. This is required for areas full of sand, bigger particles of debris and trash on the road. However, they are not really good for clearing small pollutants.
Besides cleaning the road, road sweepers also clean the garbage and pathogens from entering into the watershed as many streets-drains are connected to the nearby lake. Therefore, it eradicates all human health hazards from the street, making the road safe for everyone to walk around. Not only this, they also pick up debris which is potentially dangerous for any vehicle on the road thereby reducing accidents in the city. That is why road sweeping as well as flushing are the two important services in the city.
