Summary

The Karcher K2 is one of Karcher’s lower priced units but what it lacks in cost, it makes up for in overall performance. The 110 Bar unit produces a steady 360 litres per hour waterflow making every job super easy to complete.

The Unit comes with a 6-meter hose but can be extended with a 10-meter extension hose if the 6 meters isn’t long enough. The 5-meter cable gives you a decent reach and Karcher offer a range of accessories to help with other jobs such as cleaning the gutters.

If you are looking for something with a bit more of a kick then you should check out the Karcher K4 – we have written a review on it here.

Karcher K2 Basic Review

 

The Kärcher brand has produced an electric pressure washer called the Karcher K2 full control pressure washer.

The K2 can be purchased as the Karcher K2 full control home, Karcher K2 full control, Karcher K2 compact, and Karcher K2 compact home. Today we are looking at the Kärcher Full Control Home pressure washer.

If you didn’t want to read our in-depth review of the K2 we can sum it all up for you with this simple paragraph.

The Karcher K2 is a great home pressure washer and can be used for things like cleaning fences, tools, bins and even the car. If you are looking for a jet washer to do driveways or patios go something a little more uptown such as a petrol pressure washer.

WHY YOU SHOULD BUY THIS ONE

The Karcher K2 is a great option as a starter pressure washer for everyday home use.

The unit can be used from an outdoor tap and if you haven’t got an outdoor tap, you just need to by a Hozelock mixer tap connector and it can be used from an indoor kitchen tap.

The unit has a built-in Karcher k2 detergent suction hose set up which makes it great for cleaning cars or other vehicles, bikes, tools and bins.

Overall, the Karcher k2 full control is a great unit for home and car use

WHAT MAKES IT BETTER 

This unit is a great household pressure washer.

It becomes a better option to purchase the Karcher K2 when you take into account the items that are included as well as the storage capabilities.

All the components are able to be stored in the unit for easy storage.

It’s great for using when you haven’t got huge amounts of private space or if you have a small decking area.

KARCHER K2 HOME

For use around the home, the Karcher K2 home comes highly recommended. With the unit being perfectly tailored to cleaning out bins and garden furniture.

The Karcher k2 pressure washer is a great choice as a starter pressure washer and we would recommend for anyone with a small area to clean or a flat that doesn’t have an outdoor tap.

KARCHER K2 FULL CONTROL BEST PRICE

The price of this unit is also a very attractive reason to buy.

Most electric pressure washers fall between the £130-£170 mark so finding one that comes with lots of accessories for less than £100 is a bonus.

Also, Karcher is a very popular brand pressure washer so having a quality unit for a great price is a huge bonus.

This cheap jet wash really comes into its own, the Karcher jet wash range brims with lots of different units but the K2 really stands out due to price and the compact nature of the unit.

WHAT’S THE WATERFLOW AND PRESSURE BEST FOR CLEANING?

The Karcher K2 pressure is better tailored for cleaning cars, fences, and decking. Although the unit comes inclusive of a patio cleaner, the pressure this unit produces, although suitable, will make doing the job rather inefficient, and a higher-powered electric pressure washer will make patios and driveways much easier.

how to use detergent with Karcher k2 pressure washer

Using detergent in the Karcher K2 is fairly easy. They have a built-in detergent suction hose, which you feed into your detergent bottle and it sucks in the detergent. 

Once you are finished soaping up simply remove the tube and go back to using water.

Karcher K2 Accessories & replacements

 

 Karcher k2 suction hose

Sometimes the suction hose on the K2 can wear and get holes or snap. This is only a thin plastic tube so can be broken quite easily.

You can buy a replacement tube from lots of places so don’t worry if they get broken. 

Karcher patio cleaner head

The karcher patio cleaner head is actually included in the full control home unit. This is a great tool which makes cleaning a patio, which this unit isn’t particularly built for, a slightly easier job.

Karcher K2 Detergent bottle

The detergent tank doesn’t come as part of the K2 but can be used to feed the detergent through the suction hose. Sometimes having a bottle next to your unit can be difficult and easily spilt.

Karcher K2 vs K4

If you are looking for a pressure washer for patios, driveways or multiple cars then the K4 might be better suited to your needs. The K4 includes 20 extra BAR so cleaning harder to clean surfaces like a patio or driveway will be slightly easier. 

Also, the unit have a higher water flow rate. This means that the 30m2 per hour that the K4 cleans makes fast work of even the largest jobs.

 The K2 is better if you are struggling for storage space though as the K4 is around 1/3rd bigger in size meaning you could store the K2 on a shelf but the K4 might need some floor space.

Troubleshooting

Karcher pressure washer problems electric –

With pressure washers using water, there is always going to be the potential for electrical problems to occur. Karcher have put a hand video on Youtube to help diagnose any electrical problems that might arise on your Karcher K2.

Karcher k2 wont turn on –

If you Karcher K2 stopped working, it can be down to a number of reasons. It could be an electrical fault within the machine itself. The motor could have an issue or it’s just not getting enough power.

 If you have checked your unit and can’t find any faults, it may be down to the extension cord you are using or the power outlet you are using to power the machine.

 Karcher K2 leaking –

In my experience, pressure washers and especially electric pressure washers are prone to a little bit of water leakage.

 This can be an issue depending on where the water is leaking from.

 Most of the time the water will leak from the area where the water source is connected to the unit, this is usually caused because of an old hose connector or wear in the hose pipe.

If you have water leaking from the pump or any other part of the washer, then you might have a more serious problem that will need to look at immediately.
