Choosing the Right
High Pressure Washer

All Kärcher Pressure Washers will effectively clean most surfaces. Choosing the model that is right for you depends on several factors, including:

Whether you prefer electric or gas power.
What you will be cleaning with the pressure washer.
The size of the area to be cleaned, and how fast you need or want to work.

You should also ask yourself these questions:

Is the unit being used for a business application or simply for weekend use around the home?
What is the average number of hours you will use it per month?
Are there any use restrictions involved, i.e. will the pressure washer be operated indoors as well as outdoors?
Is mobility an issue?
Is noise level a factor?
