High pressure cleaners are designed with an industrial water pressure washer which is placed under pressure to a piston pump. This pressure creates a powerful jet of water and the stream removes stubborn stains and dirt from almost any surface. Thus high pressure cleaners are effectively used in street, facade and engine cleaning. Most high-pressure cleaners are simple to connect to the stream. Some larger units are operated with diesel. Most high-pressure cleaners heat the water up to 90 degrees centigrades. The handling of a high-pressure cleaner should be done by well-trained personnel as the impact of the water jet can cause a high risk of injury and there is the risk of damage to the surfaces treated. For more complex cleaning tasks, there are special cleaning agents to that can be applied to dirt. These high pressure cleaners can also be used in the food industry for disinfection.
With a sweeper the dirt is cleaned and removed mechanically by means of two brushes and a vacuum fan. There are mobile and attachable sweepers which can also be used as attachments in forklifts, trucks or utility vehicles. Sweepers are usually diesel or manually operated. The rotating brushes are usually located at the right-side of the sweeper and under the vehicle.
These machines are used for vacuum sweeping with a spread reach of up to 2 metres. Sweepers are operated manually but also can have a diesel engine. These machines are equipped with a high suction power and are used for drying or cleaning roads, buildings or parking areas. Sweepers have a filter in the intake air stream. This separates coarse contaminants from fine dust particles and prevents the re-entering of fine particles. For large sweepers – such as street cleaning – brushes are located on their sides, which transports the debris from the gutter to the suction nozzle. In addition, the steering for such sweepers is usually on the right hand side, so that the driver can clean more thoroughly.
Automatic wet scrubber can be operated as a pushing or as sit down device. Moreover, there is a distinction between an automatic wet scrubber with a broom and a device with two brooms. The appropriate model selection depends on the size of the floor to be cleaned. Large office buildings, warehouses can be cleaned with an automatic wet scrubber.
Scrubber/Dryers are cleaning machines and are available as hand-held or with a cab driver’s seat. These cleaning machines scrub the floor and at the same time suck the cleaning fluid. For small areas, the manual option is the best. For larger area one should use the driver’s seat option as physical strain is significantly reduced. These devices are operated with battery power. There are different widths available depending on the cleaning surface area.
With a street sweeper water is normally sprayed when sweeping the streets to bind the dust and dirt and prevent it from swirling also to prevent the ubiquitous dust generated from soot deposit and tyre wear and cleaning all kinds of waste. Furthermore, it is important to ensure that no uncontrolled plant growth damages the road surface. The street-cleaning machine is a great sweeper which is steered by a driver. The driver’s seat and the brooms are often located on the right, so it can be cleaned as close to the curb. These cleaning machines have an extremely high suction power and a large dirt tank.
