The machine everyone starts with · review
The same pump as the Universal Edition, with a foam nozzle and car shampoo — bought for the bundle, not the bar.
The bottom line Buy it if you will use the foam. The pump underneath is the cheapest machine in the range.
The K 2 Premium FJ is the Universal Edition with a Foam Jet nozzle and a bottle of car shampoo. The pump is unchanged: 110 bar, 360 l/h, 20 m²/h.
On the entry machines the accessories do more work than the pump. A foam nozzle changes what the machine is capable of on a car, because it introduces dwell time — the only variable that lifts grit without contact. Twenty extra bar would not.
Old paving, render that has gone green over several winters, a long drive. Those are flow-rate jobs, and 360 l/h is the bottom of the range. The page for the K 4 or K 5 is the honest place to go if that is the work.
One reference across Germany, the UK, France, Italy and Spain. Verified absent from Amazon’s US store — readers there are sent to a local search rather than to a page that does not exist.

It turns detergent into foam that clings to a vertical panel for minutes instead of running straight off. That dwell time is what softens grit before anything touches the paint, and it is the single most useful thing you can add to a car wash. A jet at 110 bar does not clean a car; foam and a mitt do, and the machine rinses.
The same 110 bar and 360 l/h. What you are paying for is the foam nozzle and the shampoo. If a car is the reason you are buying, that is a fair trade; if it is a terrace, put the difference towards a surface cleaner instead.
140 bar · 450 l/h · 2 100 W · integrated storage
The Bosch that finally publishes a flow rate — 450 l/h, which is what the UniversalAquatak machines never gave you.

The 125 with ten more bar and two more metres of hose — and the second of those is the one you notice.

≈ £115 / 140 €
