What We Say

What is it?

A pressure washer designed for industrial use and the hire trade, the K7 has gone on to become a very popular pressure washer with the valeting and detailing trade. A durable no nonsense design that is serviceable and repairable, the K7 is a heavy usage alternative to cheaper domestic pressure washers.

How we Tested it:

As detailers, we purchased the K7 based on recommendation from other industry users and through frustration at motors blowing on our cheaper domestic pressure washers. We have as such had the opportunity to use the machine on a large variety of vehicles and observed the cleaning power, ease of use and build quality of the machine.

We Liked:

  • Considering a modest bar output of pressure, the machine packs a punch due to how it displaces the pressure and leaves many rivals wanting.
  • Superb build quality, robust and bulletproof in feel.
  • Huge 10m pressure hose with reinforced material to help prevent splitting and wear.
  • Very economical water flow rate of 7litres a minute, ideal for mobile water tank usage.
  • Adjustable pressure.
  • Small compact design.

We Didn't like:

  • Fiddly lance change mechanism, not as simple as rival quick release systems.
  • Very heavy machine. Whilst handle helps to pick up and move it weighs almost 20kg.
  • Quite a noisy machine and as the rubber runners on the feet have a habit of coming off, the vibrations get louder.


The K7 is a fantastic pressure washer but certainly isn't the machine for all. It isn't cheap coming in well north of £400 and isn't the easiest machine to manoeuvre due to its weight, despite its small size. Certainly aimed more at industrial and business use than the home user, it does come in to its own as a frequent use machine. With a great pressure output and 10m hosing making it ideal to circle an entire car with ease, it is a detailers dream. Having said that, as a home user if you can justify the outlay, it will never let you down and long term will work out better value than regularly replacing domestic machines.
