Same summary

The Karcher PROFI DUO Advan ced2 foam nozzle is suitable for more demanding users of high-pressure cleaners who often clean larger and stubbornly dirty surfaces. It works best when applying foam to vehicles, yards or other outdoor surfaces where even distribution of detergent is important. It is worth noting that the nozzle must be compatible with the cleaner in terms of flow (700–800l/h), so check compatibility with your device before use. The advantage of the original accessory is a reliable fit and expected performance, but according to the specifications, the product is not intended for softer or very sensitive surfaces.
