Kärcher - High Pressure Washer K 5 Comfort Premium

Shifting a full season's worth of green algae from a stone patio in under an hour is where the K 5 Comfort Premium earns its keep. Its water-cooled motor — rather than the air-cooled units found on cheaper models — means you can run it continuously without pausing to let it cool down, which matters when you're tackling a large driveway or decking area rather than a quick rinse of the car. The 500-litre-per-hour flow rate and 145 bar maximum pressure put it comfortably above entry-level machines, and the 4-in-1 nozzle reduces the faff of swapping attachments mid-job.

Who Is This For?

This suits a homeowner with a decent-sized outdoor space — think patios, garden furniture, a couple of cars, and possibly a driveway — who uses a pressure washer several times a year rather than occasionally. The water-cooled motor is a genuine long-term reliability advantage if you're running sessions of 30 minutes or more regularly. If you're washing one small car twice a year, a £150 machine will do the job; the K 5's engineering is wasted at that frequency. Worth noting also that the K 5 is built from 25% recycled material, which may matter to buyers weighing up environmental credentials alongside performance.

What Buyers Say

Owners consistently praise the motor's durability and the ease of the hose reel, which keeps storage tidy and avoids the kinking that plagues cheaper competitors. The most repeated gripe is weight and bulk — this is not a machine you'll carry single-handed with ease — and some find the integrated detergent system less effective on very heavy grease without a dedicated foam nozzle purchased separately.

The Deal

Currently priced at £349.99, down from £399.99, the saving is £50 or roughly 12% off. With only two recorded price points in our history, the current price is also the lowest this product has reached, so there's no evidence it's ever dropped further. It's not a dramatic discount, but you're buying at the floor price. If you've been waiting for a dip on this model, this is the level it trades at — don't expect a deeper cut.
