Kärcher - High Pressure Washer K 3 Horizontal

This deal has ended. We are watching for the next one — check below for current live deals.

A pressure washer earns its keep the moment you realise a garden hose and a scrubbing brush simply cannot shift a winter's worth of green algae from patio slabs — and that is precisely the problem the Kärcher K 3 is built to solve. Running at 120 bar of pressure, it delivers enough force to blast moss, mud and grime from concrete, brick and garden furniture without requiring the kind of machine that takes up half a shed. The four-metre high-pressure hose gives you genuine reach around a standard patio or driveway without constantly repositioning the unit, and the horizontal design keeps it stable and compact when stored.

Who Is This For?

This machine is well-suited to homeowners with a small-to-medium patio, a set of garden furniture that sees seasonal neglect, or a car that needs an occasional proper rinse. If your pressure washing needs are genuinely occasional — a few sessions per year rather than weekly commercial-grade work — the K 3 sits at a sensible level of capability without over-speccing. If you have a large driveway, render that needs regular cleaning, or a two-storey property with gutters to reach, you should be looking at the K 5 or above.

What Buyers Say

Owners consistently praise how quickly the K 3 gets going — minimal assembly, straightforward connections, and noticeable cleaning power from the first use. The Dirt Blaster lance attachment draws particularly positive mentions for stubborn staining on block paving. The most repeated limitation is the relatively short power cable, which can create awkward routing on larger jobs, and some owners note the hose connections feel less premium than the machine itself.

The Deal

The K 3 is currently £99.99, down from £119.99 — a £20 saving. However, our price history shows this product has never actually sold above £99.99 since we began tracking it, which means the "was" price warrants some scepticism. For context on how this compares to the wider market, our best pressure washer deals guide covers the current landscape honestly. At £99.99 it is a fair price for a Kärcher entry-level machine, but do not let the percentage saving be the reason you buy it.

Frequently Asked Questions

The Kärcher K 3 Horizontal delivers a maximum pressure of 120 bar with a flow rate of 380 litres per hour, making it well suited for light-to-medium cleaning tasks. It connects to a standard garden tap via a 3/4-inch threaded hose connector, which is the universal fitting used on most UK garden hoses, so no adaptor should be required.

This model handles patios, garden furniture, bikes, and moderately dirty cars with ease, and the horizontal motor design keeps it compact and stable during use. However, it is not suited for stripping heavy moss from large driveways or blasting ingrained grease from workshop floors — for those tasks you would need a K 5 or above with a higher flow rate and a turbo nozzle as standard.

Based on the 12 data points tracked, £99.99 is both the lowest and the only price this unit has been recorded at, meaning there is no evidence of it ever being cheaper at this retailer. The 'was £119.99' framing suggests a previous RRP, but the tracked data does not confirm a prior drop from that higher price, so treat the discount badge with some scepticism rather than as a confirmed saving.

The Bosch UniversalAquatak 130 edges ahead on maximum pressure at 130 bar versus the K 3's 120 bar, and it typically includes a turbo nozzle in the box, which the base K 3 kit does not always feature. That said, Kärcher's accessory ecosystem is broader and more widely stocked in UK retailers, so if you plan to add a patio cleaner or foam nozzle later, the K 3 gives you more upgrade flexibility.
