The K3 Power Control delivers a bit more water pressure than the K2 Power Control. According to the manufacturer, the K3 can clean more surface area in one hour than the K2. In practice, however, we could hardly notice any difference. The K2 cleans just as thoroughly as the K3. Comfort

The Kärcher K2 or the K3 – which one should you buy? In this post, we compare the two models and show the differences. Cleaning is comfortable and unproblematic with the K4 Power control as well as with the K3. Both have a display for the pressure on the gun, the same vario lance, and dirt blaster lance. The K4 pressure hose has a couple of advantages; it is one metre longer and a bit more flexible, which makes it easier to work with, especially on larger objects such as SUVs or vans. Versatility Although the K4 has some plastic parts, it seems to be of higher quality and is a bit more stable than the K3. The parts do not wobble or vibrate as much and the pressure hose is much more flexible. Included with the K3 is the adjustable Vario Power spray lance, and you also get a Dirt Blaster spray lance which is specifically for cleaning stubborn dirt on patios. As you might expect, the K3 is just as effective at cleaning cars, as it is bikes, though again we found that it was possible to go up a couple of notches on the Power Control screen for a bit more cleaning power. You just need to make sure you don’t get too close to the object you’re spraying, or spend too long on one area.

The K3 is a great all-round pressure washer that has bike-specific cleaning abilities and some nifty smarts thrown in to make it effortless to use. But is it really essential for cyclists?

Kärcher always on hand - Our specifically designed app for smartphones is full of useful hints and tips, from machine set-up to helping you get the job done As Kärcher no longer produces a compact version of the K3, we compare the K2 Power Control with the K3 Power Control.

Connect the app, however, and you can tell the K5 what you’re trying to clean, and it will set the required pressure and tell you how to adjust the lance for every stage, so as you clean the car or power-wash the driveway, you’re using the right spray pattern and setting for every step. Buy the Home version and Kärcher also bundles the T5 Surface cleaner for a thorough clean of any hard surfaces in your garden. You pay a lot for the smart features, and we’re not sure that using the app to control the lance is really that convenient. Still, if you want the ultimate in high-tech pressure washers, nothing else even comes close.

Kärcher has a wide range of pressure washers, but which is the best one for you?

Its secret weapon is its Power Control Gun and matching Vario Power spray lance. You can switch between three different pressure settings and adjust the spray pattern with a twist of the nozzle; you can switch from a high-powered jet to a softer, flatter spray in a jiffy. Whether you’re washing mud off the car or trying to blast mould and algae from your patio, you get what you need without having to lug around a bunch of different tools. As with the Muc-Off pressure washer, the K3 is a strictly home-only affair, due to the need for mains power and an external water supply. Bosch recently released the Fontus, a lithium battery-powered portable pressure washer with a built-in 15L water tank, which is much more suited to that task, if that’s what you’re after.
