You can also expect the same quality that Karcher has always provided with a noncorrosive and patented pump. The unit also has a built in safety valve to ensure that there is pressure overload protection.


The Karcher K2 is definitely made for light duty cleaning applications. This cold water pressure washer delivers 1600 PSI of pressure which makes it an ideal choice for smaller cleaning projects such as cleaning your garage floor or washing your car.

The pump in the K2 offers water output of 1.25 gallons per minute compared to a standard water hose that has an output of 10 gallons per minute. So with this electric pressure washer you really can save a lot on your water bill if you clean often.

The pressure washer will operate out of a standard 120V AC outlet and you will be happy to know that it is equipped with a ground fault circuit interrupter. This ensures that if there is a change in voltage the machine will automatically shut off for your protection.

The motor runs on 13 amps and the motor only comes on when you squeeze the trigger. This is also another feature that helps you to conserve on both water and on electricity.

It is just what you need for smaller jobs that do not require as much brute force as would be necessary for a gas powered pressure washer.

Comparisons/Possible Alternatives

The Karcher K2 has less PSI and less GPM than the Sun Joe SPX3000 and the Sun Joe is more affordable, which makes it a much more attractive purchase for those who are buying an electric pressure washer for the first time.

Truth is, what Karcher has over Sun Joe are better resources and sturdier and more durable machines which cost less overtime. This is also where Karcher does better than GreenWorks.

When it comes to the AR Blue Clean Electric washer though, you may say that it comes to a bit of a tie with the Karcher K2 in both performance and price.


The Karcher K2 Plus Electric Power Pressure Washer is a light duty, cold water electric pressure washer and it is rightly marketed as such. While some may say that it is not a powerful unit, it does accomplish light duty tasks just like it should as specified by the manufacturer.

So if you need something more powerful this is not the one and you can find another more powerful option right here. But if you are looking for an electric pressure washer that offers light duty cleaning then this is definitely a great pick.

It is affordable priced, lightweight and ultra-portable and is the ideal residential pressure washer for light duty tasks.
