With the development of the city, the cleaning work of all walks of life has basically changed from the original manual cleaning mode to the electric sweeper cleaning mode, so which roads can the electric sweeper clean? Let's take a look at the picture below.

Electric sweeper can sweep all kinds of roads, such as asphalt concrete pavement, cement concrete pavement, plant mixed asphalt macadam pavement, neat stone or strip macadam pavement; secondary pavement includes asphalt perforated macadam pavement, road mixed asphalt macadam pavement, treated asphalt macadam pavement, semi neat stone pavement; medium pavement includes mud bound or Graded Macadam pavement, water bound macadam pavement Gravel pavement, disordered stone pavement and other granular materials; low grade pavement includes various granular materials or improved soil of local materials, such as slag, gravel soil and gravel soil pavement. Under such road conditions, the sweeper can easily complete the cleaning work.

The electric sweeper, which can be used outdoors, is a common cleaning equipment in residential areas and factories. Electronic sweeper is widely used outdoors, especially in parks and country roads. Therefore, what should we pay attention to when using sweeper to clean the road? Here are three points for attention:

When electric sweeper sweeps, pay attention to pedestrians at all times, just as when driving. In order to avoid hitting pedestrians and causing unnecessary impact, electric sweeper should pay attention to safety in the process of cleaning, do not be careless.

When the electric sweeper works, the driving speed should not be too fast, and the filter element should be unobstructed every time. After cleaning, the garbage and dust in the dustbin should be removed in time to avoid secondary pollution.

The electric sweeper without water absorption function should bypass the ponding section and should not be cleaned in rainy days. The other is that when the electric sweeper passes through the tunnel, the front brush will roll and splash the water to other places. Some objects will leave traces on the ground that are difficult to clean after touching the water.
