The machine everyone starts with · review
The entry Kärcher, sold as a bundle with a patio head — which is the part that decides whether the machine gets used.
The bottom line Buy it for the bundle rather than the pressure: the patio head is worth more than the twenty bar between this and the next model up.
The K 3 FJ Home is the machine most people meet first, and it is sold on the wrong number. 120 bar is the headline; what actually decides how quickly a terrace comes clean is the volume of water the pump moves, and Kärcher does not publish a flow figure for this model at all. That absence is worth stating plainly rather than filling with an estimate.
This version is the Home bundle, which means the T 1 surface cleaner is included. A surface cleaner is a housing with a spinning jet inside it: it covers a wider path, keeps the water off the wall behind you, and — most importantly — removes the striping that a hand-held lance leaves when your arm speed varies. Bought separately, that head costs a meaningful fraction of the machine.
The Foam Jet nozzle in the name is the second half of the bundle. It turns detergent into foam that clings, which is what makes low-pressure cleaning work on render, plastic garden furniture and paintwork. Both accessories point at the same conclusion: on this machine, the accessories do more of the work than the pump.
The dividing line is not the material, it is how long the dirt has been there. Annual maintenance washing — garden furniture, a bike, a car, a terrace done every spring — sits comfortably inside what this machine does. Black-spot lichen on old paving, or render that has gone green over several winters, is a different job: the answer there is dwell time with a patio treatment rather than more pressure, but a machine with more flow shortens it considerably.
Kärcher’s Click&Clean bayonet is proprietary. Lances, brushes and surface cleaners sold for Nilfisk’s Click&Clean or for the M22 thread used by trade machines will not fit without an adapter, and every adapter is a joint that can leak. If you expect to buy accessories later, that decision is being made now, at purchase, and it is worth reading the adapters page before choosing the machine.
One Amazon reference covers Germany, the UK, France, Italy and Spain, which is unusual and useful: the same model, the same spare parts, the same accessories, whichever store you buy from. It is not listed on Amazon’s US store.

For a terrace that is washed every year, yes — particularly with the T 1 head in the box, which spreads the same water over a wider path and stops the striping a lance leaves. For paving that has not been touched in five years, 120 bar will lift the green but will take several passes on the black, and that is where the step up to a K 4 or K 5 earns its money.
It mixes detergent into the jet as thick foam rather than spraying it as liquid, so it clings to a vertical surface long enough to work instead of running straight off. On a car or a rendered wall that dwell time is the whole point — the detergent does the softening, and the water then only has to carry the dirt away.
Kärcher's K series can, with the suction hose and filter sold separately, but this listing does not include one. Two things matter if you try it: the machine must never run dry, and a water butt has to be high enough — or the hose short enough — that the pump is not asked to lift more than it can.
