Hello all, just purchased A Cordless Battery Pressure washer High Power Portable model NORSE Professional SK25i What a delight, the power washer is well made and very well constructed. I found it easy to assemble and started to use it within an hour of unpacking. Tip: make sure you charge the battery fully before you try, also READ the guide book first and you will have no problems with the operation and assembly. In use, do NOT expect it to be as powerful as a 240v mains edition, it does remove dirt extremely well and has in my opinion a very powerful jet for a 20v system, best on the market, wash the car, clean your outside windows, patio, path, etc all in all a great product.
