Kärcher K2 Power Control High Pressure Washer

A pressure washer that costs under £100 but connects to your smartphone sounds like marketing fluff — until you realise what the app actually does. The Kärcher K2 Power Control uses its companion app to recommend the correct pressure setting for each task, whether that's decking, car bodywork, or patio slabs. For anyone who has ever blasted a fence panel off its fixing or stripped paint from render by using too much pressure, that guidance is genuinely useful rather than a gimmick. It delivers 110 bar of pressure and 360 litres per hour flow rate, which puts it firmly in entry-level territory, but sufficient for drives, garden furniture, and moderately grubby patios.

Who Is This For?

This is the right machine for a homeowner with a modest suburban garden who needs to clean their car, clear moss from the path, and blast algae off the patio a few times a year — and who wants a little more confidence than a bare trigger and no guidance provides. The app support makes it particularly well-suited to first-time pressure washer owners. If you have a large driveway, extensive block paving, or genuinely stubborn ingrained grime, you will outgrow the K2 quickly and should be looking at the K4 or K5 instead.

What Buyers Say

Owners consistently praise the lightweight build and how easily it stores away — it genuinely fits in a cupboard without drama. The app integration receives warmer feedback than expected, particularly from those new to pressure washing. The most common complaint is the relatively short hose at six metres, which forces you to move the unit frequently around larger areas and becomes irritating fast.

The Deal

At £99.97, down from £149.99, you're saving just over £50 — a 33% reduction. This product is newly tracked on our site, so there is no price history to confirm how often it hits this level or whether it has been lower. That's an honest limitation worth noting before you commit. That said, £99.97 for a branded Kärcher with app control is a credible price — just don't assume it's the floor.
