Pressure per euro against running time
Why pay three times more for the same headline pressure?
The bar figure is identical. What separates these machines is what happens after the first twenty minutes.
| Compared on | HCE2600 | K 7 WCM FJ |
|---|---|---|
| Maximum pressure | 180 bar | 180 bar |
| Flow rate | Not stated in the listing | 600 l/h |
| Area performance | Not stated | 60 m²/h |
| Motor cooling | Not stated | Water-cooled |
| Hose | 5 m | 10 m |
| Power | 2 400 W | Not stated |
A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these machines answer different questions.
Buy the Scheppach if the budget is the constraint and the work is occasional — 180 bar is 180 bar, and on concrete it will do the job.
Buy the K 7 if the machine will run for an hour at a time. Water cooling is a durability specification, and 600 l/h is what shortens the session.
No, and this pair is the clearest illustration on the site. Without a flow rate you cannot tell whether a machine moves 300 or 600 litres an hour, and that is what decides how long a terrace takes. Both quote a maximum, measured with the trigger shut.
Running time. An air-cooled domestic machine is designed for intermittent use and relies on you letting go of the trigger. Water cooling routes the incoming supply around the motor, so long sessions do not shorten its life.
180 bar max · 2 400 W · 5 m hose · Quick-Connect
A hundred and eighty bar for the price of an entry machine — and the compromises are in the hose and the flow figure.
Best for: Concrete, stone and a drive, where the pressure is usable and the short hose is tolerable
≈ 99 €
180 bar · 600 l/h · 60 m²/h · water-cooled motor
The top of the domestic range, and the only one here whose motor is water-cooled — which is a statement about running time, not power.
Best for: Large areas cleaned in one session — long drives, farmyards, several vehicles — where the machine runs continuously rather than in bursts
≈ £590 / 500 €
