Kärcher - High Pressure Washer K 3 Horizontal

A garden patio that would take an afternoon of scrubbing with a brush can be done in twenty minutes with the Kärcher K 3 — and that time saving is the real case for ownership here. This is an entry-level pressure washer rated at 120 bar, which is enough to shift algae, mud, and grime from paving slabs, garden furniture, and wheelie bins without the machine being so powerful it damages softer surfaces like decking or render. The four-metre high-pressure hose gives you enough reach to work around a car or a modest patio without constantly repositioning the unit.

Who Is This For?

This suits a flat or house owner with a small-to-medium outdoor space who wants results that a hosepipe simply cannot deliver, but who doesn't need a machine running for hours at a time. If you're cleaning driveways regularly, tackling heavy agricultural dirt, or working commercially, you'll outgrow the K 3 quickly and should look at the K 5 or above.

What Buyers Say

Owners consistently praise how compact and light the K 3 is — the horizontal design means it stores flat in a cupboard or shed without eating floor space. The most common criticism is the hose length: four metres sounds adequate on paper but in practice, once the machine is positioned safely near a socket, that reach can feel limiting around a larger vehicle or driveway. A handful of owners also report the plastic connectors feeling less robust than expected at this price point.

The Deal

Currently priced at £99.99, down from £119.99, the £20 saving represents 17% off. Because this product is newly tracked on our site, there's no price history to confirm whether £119.99 is a genuine regular retail price or a softened anchor — treat the "was" price with appropriate scepticism until more data accumulates. That said, £99.99 sits at the lower end of the Kärcher K 3's typical market range, making this a reasonable entry point if you've already decided this model suits your needs.
