Kärcher is a leading brand in pressure washers, and owning the best Kärcher pressure washer is an investment that can save you time on several outdoor cleaning tasks.

With spring in sight, many of us will be perfecting our garden design to (hopefully) make the most of some warmer weather. Pressure washers can help with this process because rather than manually scrubbing away at dirt, you can simply blast away stubborn mud and mildew from your patios and decking, or even hose down your bike.

Kärcher's pressure washers come in a variety of sizes, prices and power options, and with a range of accessories. If you're looking for a powerful machine to clean your driveway then you'll want to look for a higher pressure model, while smaller pressure models can be great for cleaning smaller garden spaces. 

And Kärcher's user-friendly Home & Garden app is surprisingly handy for guiding you through the stages required for your clean. 

Use this guide to the best Kärcher pressure washers available now to learn which model is best for your home.

It comes with four cleaning settings to choose from, and the application of detergent will effectively blast dirt on patios and driveways and clean more delicate materials, such as wood. 

It's not as powerful as the K7, but it does come with a high-pressure gun and hose, plus full control lances and a cable, which are great for cleaning small-to-medium-sized patios and decking, and even cars and bikes.

If the K7 is outside of your budget, then the next best premium Kärcher pressure washer is the K4 - a good all-rounder which effective blasts through larger patios and driveways. 

The K4 comes with a vario power spray lance, a dirt blaster spray lance and a surface cleaner brush, and the tools can be stored on board. It also has a retractable handle for increased convenience when storing it away. 

It's slightly less powerful than the K7, and comes with a smaller hose, but it is very effective - especially if you're looking for a pressure washer you don't want to use that often. 

Notably, it's also very quiet. And you'll appreciate this benefit during longer cleaning jobs. The only criticism is that it's quite bulky, making it harder to carry around.

It won't be suitable for cleaning stubborn dirt out of your driveway, but that isn't the point of this washer. It's designed for quick and easy jobs, utilising effective gentle pressure that's perfect for a quick rinse of dirty clothing or objects.

This is Kärcher's smallest and cheapest pressure washer, but it's excellent value for money. It comes with a trigger gun, hose and lance which can all be neatly stored on the machine, and an integrated suction tube allows detergent to be applied to any surface being cleaned.


How to Choose the Best Kärcher Pressure Washer

Kärcher is a leading brand so whichever machine you opt for will deliver high-quality results, but these are some considerations to make before making your purchase.

Cost

If budget isn't a factor, then K7 is one of the most supreme machines available and well worth investing in. The K2 Full Control Pressure Washer is more cost-friendly but offers fantastic value for money.

Usage

If you only plan to use your pressure washer once in a while on small jobs, like cleaning brickwork or bikes, then a cheaper model such as the K2 Full Control Pressure Washer or Kärcher K4 Full Control Home Pressure Washer will do the job. But for regular, bigger jobs, the K7 will offer the best results. 

Pressure

The bigger the pressure, the bigger the jobs your pressure washer can handle. For cleaning bikes, furniture and decking then a 100 bar pressure will suffice, while larger jobs such as cleaning large patios will likely require a 130 bar pressure or higher. 

Hose length

If you want to clean the end of your drive, you'll need to go for a model with a hose that can reach (the Kärcher OC3 Portable Cleaner is a great cordless alternative). But if you just need to clean your bike in the back garden, a longer hose length isn't as essential.
