Aside from the size differences, the differences between the “Compact” and “Control” models are the trigger designs, hose lengths (only on K5 models) and detergent application method. This is one of Karcher’s most expensive home pressure washers. Not only does it cost more than their other domestic models, but it’s also priced above competing models from other brands. It’s basically the same as the power control version (LED-Display) except you can select the different power settings directly on the gun without bending over to adjust the water pressure. Additionally, you can connect the pressure washer to the Kärcher smartphone app and control it remotely via Bluetooth. It’s only available on certain K5 and K7 models. Karcher Compact

This system performs beautifully. It’s much easier than using a separate detergent bottle, and you can also adjust the ratio at which the machine mixes the shampoo with water, meaning that you can decide how soapy or watery you want the detergent to be. So what are the differences? The compact version is more compact, it is the same spec as the full control counterpart. So the engine is the same, in terms of accessories you get a lance, however, the compact version is more basic and doesn’t have the visual settings of the full control version.

Every single model comes with a different range. There are the Premium versions, Power Control versions (formerly full control), Home Kits, Car Kits, Compact versions and, for the top models, the Premium Smart Control versions. Karcher Premium This pressure washer comes complete with a vario spray lance for general washing & low pressure detergent application & a dirtblaster that delivers outstanding cleaning performance using concentrated rotating pressure for stubborn soilage and marking such as mould spots. A retractable detergent suction hose is also included allowing for the easy application of detergent while you are cleaning.There is an LED-Display on the trigger gun that allows you to comfortably monitor the different power settings (from soft to hard). Karcher Smart Control Depending on which model you are looking at, they all have the same spec. For example, if you were looking at getting the K5 Pressure washer, there is no difference in performance whether you go for the home, premium or compact. They all have a 2100-watt motor, giving 145 bar pressure. They all come with an 8m hose and have a flow rate of 500 litres per minute. So the internal power and pressure are the same, whichever model you choose. This product is covered for DIY & Home use ONLY and any use in a commercial/business environment will invalidate all guarantees. We tested all models ourselves; what is our personal opinion? The best electric Karcher Pressure washer for home use

On the plus side, this pressure washer’s weight helps to keep it steady while it’s in use. There was no danger of it toppling over, even if the hose was accidentally tugged on. That said, the hose is long enough that you can easily work your way around a car without having to yank on the main unit, and the fact that the hose didn’t kink or coil was a big bonus. These are the smaller and lighter models. They are easy to transport and store, and they are cheaper than the premium/power control models. Home-KitThe detergent bottle isn’t built-in, you get a suction tube that you insert into your own bottle that you would have to place on the ground next to the pressure washer.

The highest possible water pressure is not an advantage when washing a car. On the contrary, more than 130 bar can damage the paintwork or even leave dents. The LCD display, along with the bluetooth connectivity, is another feature that Karcher has put into place to make this pressure washer easy to use. The fact that you can control pressure using the two buttons on the trigger gun is definitely handy, with the LCD screen showing you the current pressure that you’re using. The way I see it, this higher price is justified by this machine’s power . You’ll struggle to find a home pressure washer that offers 180 bar for a lower price. It takes the machine out of the domestic realm and into the heavy-duty category, yet it costs significantly less than a professional model.That said, although 180 bar may be its maximum, this pressure washer provides a little less than that when you have it on its strongest setting. However, it comes with a boost function that you can use to give yourself an extra 15 bar of pressure whenever you’re struggling with stubborn dirt, which is very useful. All versions of the same model number (e.g. K5) have the same flow rate, pressure rating, motor-cooling mechanism, power rating and maximum water feed temperature.
