The car wash is going well with the Vario-lance and the brush, it is for my needs sufficient pressure and-fill in the detergent container liquid is well distributed. Car washing is thus possible quickly and thoroughly. The material of the high-pressure hose made a little inferior impression also tended the hose to tangle.
The rotary nozzle has a sufficient pressure, I've cleaned my yard paving stones so, old color patches and weeds away at Ritzen. The surface cleaner T50 I have not really used and can not say anything except that he does not splashing around.
The device is small, handy and can carry everywhere. The power cable and the high-pressure hose have fallen quite short, here you have at least the power cord a good waterproof extension have.
Here was already defective at the second or third time the water hose connection, which is why I returned to the high-pressure cleaner. Apart from this defect, the device was perfectly fine. Whether this defect is just a random manufacturing defects or this regularly in these devices is the case I can not say.
Overall I would recommend these high-pressure cleaners for occasional cleaning of the car and a small courtyard.
