What is the Kärcher K4 Full Control Home?

The Kärcher K4 Full Control Home is a solidly built and powerful pressure washer with plenty of accessories. It comes with a trigger handle, a patio cleaner, a lance with an extension that doubles its length, and two nozzles: rotary and fan jet. It’s also supplied with a bottle of stone detergent that slots neatly into a space at the top of the machine.

Assembly is quite a faff, with various plastic bits to fit using six screws, and you need to read the instructions to understand where to stick them. It feels like too much effort and I resented it. This isn’t Ikea flatpack; you’ve just spent a significant amount of money on a pressure washer and now you’re helping to assemble it.

Also there’s no reel for the pressure hose, so storing the hose and power cable is a bit hit-and-miss. On the plus side, this makes the machine compact and stable, with a low centre of gravity. But again you’re left thinking: “Have I somehow bought a budget model? I paid good money for this!”

Samsung Galaxy S10 128GB Black – 60GB of data on EE with free Samsung Galaxy Buds

A great deal with nothing to pay upfront for the brand new Galaxy S10. This pre-order deal also includes the Samsung Galaxy Buds.

However, it’s performance that really counts and the Kärcher doesn’t disappoint. Its patio washer has the best design and performance in its class. The head is articulated really well, so it’s manoeuvrable like a vacuum cleaner. There’s a knob on top of the patio cleaner to adjust the power, and the fan jet nozzle is adjustable too.

On the trigger handle, there’s an illuminated display to indicate power. It’s tempting to think this is a control and tap it, but it’s not. Instead, it simply indicates how powerful the water is, with icons to indicate the appropriate power for various jobs, based on the tool you’re using and any adjustment on the tool,

Should I buy the Kärcher K4 Full Control Home?

I was frustrated by a few points that felt cheapskate for a not-especially-cheap product. But Kärcher is known for its quality pressure washers and the K4 Full Control Home doesn’t disappoint. The build quality and performance are superb.
