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.
| Material | Pressure |
| Tools | 100 - 120 bar |
| Machines & vehicles | 110 - 120 bar |
| Gutters, pipelines & sewers | 120 - 140 bar |
| Greenhouse facades | 120 - 140 bar |
| Concrete and stone | 110 - 170 bar* |
| Brickwork | 140 - 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.
Cleaning liquid
Not every high pressure cleaner is suitable for
the cleaning or disinfection of liquids. When you would like to use this application it’s important to keep this in mind when you decide to buy a high pressure cleaner.
Nozzles and attachments
When you want to buy a high pressure cleaner it’s important that you also buy
the right nozzles and attachments. These accessories provide a different beam and a different way of cleaning.
Hose reel
High pressure cleaners for horticulture are mostly equipped with a large amount
of metres of hose. This way it’s possible to clean bigger surfaces from one point. To help you with pulling the hose you can consider using an
electric hose reel.
