Not so good: It’s not as portable as other machines as this one has no wheels. For larger areas or more tougher cleaning jobs, you may need a more powerful machine.
Our verdict: A very good budget machine for everyday cleaning jobs. No frills but great price.
The Karcher K2 Compact is one of the best selling pressure washers right now, even after being on sale for several years. So what makes it so great? Read our review to see if this model really is worthy of a “best seller” title.
The yellow cleaning machines from Karcher are very well known now in the UK and the K2 Compact is the cheapest of Karcher’s extensive UK range with a retail price (RRP) of £85. What makes it more attractive though is that we have seen the price discounted by as much as 35%.

The next model up is the K2 Full Control which has the same motor and performance but comes with the Full Control Click Vario adjustable lance along with a telescopic handle and wheels. Moving up again to the Full Control Home version sees the addition of a patio cleaner. It’s worth shopping around as there is quite often not much difference in price between these K2 models.
We describe on this page the differences between the K2, K4, K5 and K7 Karcher models. The K2 is the budget end of Karcher’s range and features a 1400w power output motor (the same as in the rest of the K2 range) and while this isn’t the most powerful of pressure washer motors we have reviewed, it will certainly be enough for light to mid cleaning duties such as patio/driveway cleaning or car washing.
The Karcher K2 Compact power washer delivers 110bar water pressure and again, while this is the lowest of the Karcher models (all K2 have 110bar pressure by the way) it will still be enough to shift most dirt and grime. It’s only when you go to the more expensive K4 range that pressure increases by 18% to 130bar.
Water flow rate on this (and all K2 models) is 360 litres per hour, or equivalent to 6 litres a minute which, while not the highest, is a reasonable amount of water flow for light duties.
Possibly one of the most attractive features of the K2 Compact is its weight, weighing in at only 4kg. To put this into perspective, the K4 models weigh around 11-12kg. The K2 does need to be light though as you will need to carry it into position as the K2 Compact does not have wheels (you will have move up to the K2 Full Control for wheels).
The K2 Compact does have a neat carrying handle built in so portability should not be too much of a problem. As with other K2 models, the water hose length is 4 metres long, so you should not actually need to move the machine around too much anyway when in use.
As a budget machine, the K2 Compact does not come with loads of accessories but you do get the essentials. This model comes with a basic lance with high-pressure jet and also a “Dirtblaster” attachment that has a rotary end nozzle that gives a narrow and powerful water jet which is useful for shifting that stubborn moss on the patio!
Both these attachments and the electric cable can be stored neatly on the unit itself.
