Property me the Kärcher concerned to clean my concrete paving stones in the courtyard entrance and several other areas with concrete slabs. The assembly lasted about 20 minutes, the imaging in the manual is rather modest, has nevertheless worked well. Commissioning is easy, all connections are provided with well-functioning plug closures. The trigger gun is easy to use, as an accessory, there is a rotary nozzle and a "Vario Power" nozzle. Both are very functional and useful. I personally prefer the Vario Power nozzle, you can vary the power by simply turning on the shaft. The T-Racer is supplied for cleaning flat surfaces just great. He has circumferentially around a splash guard, so that I could clean my terrace to have "dirty" without behind house walls or windows. Had me a suction hose bought with non-return valve, so I can from the rain barrel or suck from a bucket, if no water connection is nearby. All in all a very, very decent device that worked fine so far and is easy to use!
