Karcher pressure washers are made with quality parts and are ideal for all domestic situations. With the Karcher K5 Compact you save time when cleaning your driveway or patio and you get a better result than if you use a less powerful Karcher pressure washer.

Karcher recently released a new pressure washer range for 2017 of which the Karcher K5 Compact pressure washer is one.

But did you know that the water-cooled motor gives this unit more power and a longer life?

Read the following review for more information.

Karcher K5 Compact Features

  • 2100 watts
  • 145 bar pressure
  • 500 litres p/h water flow

The figures above show that the Karcher K5 Compact is a medium size domestic pressure washer. As such this pressure washer is ideal for the quick cleaning of your driveway, garage, patio or garden path etc.

For stubborn graffiti or grease and oil stains we would recommend the Karcher K7 Premium pressure washer.

Water Cooled Motor

Water cooled motors are much more likely to lead a longer life than air-cooled motors due to tighter build tolerances. Air cooled motors also tend to be noisier than water-cooled ones.

Water cooled motors tend to be found in better grade pressure washers while air-cooled motors are generally found in low-cost pressure washers.

As the name implies the Karcher K5 Compact is well, err, compact. Designed for easy maneuverability and transportation the K5 Compact is fitted with two carrying handles.

This pressure washer is very light at 11.5kg without accessories and measures just 5.16 x 29.5 x 28.2 cm for easy storage.

Quick Connect

The Karcher K5 Compact is fitted with a Quick Connect connection device which makes attaching the lance or high-pressure hose as easy as 1,2,3.

Filtered Suction Capability

The K5 Compact can source water from tanks, buckets or other water butts and the filtered suction capability comes in handy here as all incoming watered is filtered to eliminate large impurities.

Auto Stop 

The Auto Stop feature basically stops operations when the trigger is released. Once the trigger is pushed down again the pressure washer will resume operations. Auto Stop saves you electricity usage and it leads to a longer motor life.

Area Performance

You can expect to pressure wash an area of 40m² in an hour with the Karcher K5 Compact.

Two Types of Lances

As the name suggests the vario lance allows you to change the power of the water stream. The dirtblaster lance provides a circular water stream for maximum cleaning power.
