High pressure hose
Written by René Mondt | Last update: 23-6-2021

Many greenhouses use high pressure cleaners to clean floors, glass, gutters, machines and more. A high pressure cleaner makes it convenient to clean stubborn dirt fast. Much more efficient than when you would do this by hand. There are different types of high pressure cleaners with different advantages and features. So how do you choose the best suitable high pressure cleaner? Our product specialist will explain it in this topic.

High pressure cleaner choice

In order to make it easier to choose the right high-pressure cleaner, you need to take the following points into account:
  • Pressure of a high pressure cleaner
  • Water usage of a high pressure cleaner
  • Hot water or cold water
  • Cleaning liquid
  • Nozzles and attachments
  • Hose reel

Pressure of a high pressure cleaner

The pressure of the high pressure cleaner is indicated in bar. The higher the pressure, the more powerful the water beam, the better the cleaning results. Most of the high pressure cleaners have the ability to adjust the pressure manually. The required amount of pressure depends on the material that needs to be cleaned. In the matrix below you can see the pressure that is most suitable for cleaning different materials.

Tools100 - 120 bar
Machines & vehicles110 - 120 bar
Gutters, pipelines & sewers120 - 140 bar
Greenhouse facades120 - 140 bar
Concrete and stone110 - 170 bar*
Brickwork140 - 170 bar
* Depending on the surface and amount of dirt

Water usage of a high pressure cleaner

The water usage of the high pressure cleaner shows how much water the machine uses per hour. When you compare the water usages of different high pressure cleaners, this is the rule: the high pressure cleaner with the highest water usage at an equal pressure is the machine with the best cleaning ability.

Warm or cold water

An important choice when buying a high pressure cleaner is deciding whether you are going to clean with cold or warm water. A cold water high pressure cleaner is most suitable for cleaning non-sticky dirt like dust and moss. Sticky dirt can also be cleaned with a cold water high pressure cleaner but this takes a lot longer than when using a high pressure cleaner with warm water. Besides this, warm water also kills bacteria (if the water is warm enough. Surfaces that have been cleaned with warm water also need a shorter time to dry. 

Note: not every high pressure cleaner heats the water itself. In this case you need to connect the hose to a warm water connection.

Nozzles and attachments
