Which is the Best Kärcher Pressure Washer?
1. Kärcher K7 Premium Smart Control Pressure Washer
The best premium pressure washer
Weight: 18kg | Cordless: No | Dimensions: 46.3 x 33 x 66.7cm | Max pressure: 180 bar | Max flow rate: 550 l/hr | Hose length: 10m
The Kärcher K7 Premium Smart Control Pressure Washer is the only place to start when talking about Kärcher pressure washers.
This premium model has incredible power (courtesy of a 180 bar max pressure, the highest on this list), which makes it well-suited for cleaning large patios and driveways. It also comes with brilliant accessories, including the 3-in-1 Multi Jet lance (Vario, dirt blaster and detergent), which lets you select the perfect cleaning mode for your application.
It boasts on-board storage for the accessories, which include a telescopic handle, the full control lances, and the T7 T-Racer Surface Cleaner to help you clean large surfaces.
Like all premium products worth their salt, this is a fairly costly model. But that's simply because it's the best Kärcher product, and one of the best overall pressure washers. It also comes with an app to guide you through the stages required for your clean.
2. Kärcher K2 Full Control Pressure Washer
The best for first-timers
Weight: 4.6kg | Cordless: No | Dimensions: 32.2 x 21.2 x 40cm | Max pressure: 110 bar | Max flow rate: 360 l/hr | Hose length: 6m
The Kärcher K2 is the standout choice if you have a modest budget and don't feel too confident using one for the first time.
This is a simple-to-use, affordable pressure washer that handily guides you through which pressure to use depending on your task of choice. 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.
It's lightweight too, easy to carry with you, features on-board storage and once you've finished, it's easy to store away.
3. Kärcher K4 Full Control Home Pressure Washer
The best mid-range option
Weight: 12kg | Cordless: No | Dimensions: 41.5 x 30.5 x 58.4 cm | Max pressure: 130 bar | Max flow rate: 420 l/hr | Hose length: 6m
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 quiet bulky, making it harder to carry around.
4. Kärcher OC3 Portable Cleaner
The best cordless cleaner
Weight: 2.17kg | Cordless: Yes | Dimensions: 27.7 x 23.4 x 20.1 cm | Max pressure: 5 bar | Max flow rate: 2 l/min | Hose length: 2.8m
The Kärcher OC3 Portable Cleaner is brilliant for those who love spending time in the great outdoors. It is a cordless and compact option you can use at home to clean down your bike or muddy boots (or the muddy dog) after a walk, and you can take it in the car for quick washes after a hike.
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.
Plus, it utilises on-board storage for the spiral hose and trigger gun under the removable water tank, so it's easy to transport.
5. Kärcher K2 Compact
The best budget pick
Weight: 39 x 22 x 18cm | Cordless: No | Dimensions: 3.7kg | Max pressure: 110 bar | Max flow rate: 360l/hr | Hose length: 4m
The K2 Compact is Kärcher's best budget pick, and despite lacking some of the power and features of the other pressure washers in this list, its 110 bar pressure is effective on both delicate surfaces such as your car, or harder surfaces such as brickwork.
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.
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.
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.
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.
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.
