Firstly thank you for your prompt delivery of the Norse SK135 jet wash unit. I only ordered it on the 11th February and it arrived the following day. I am Pleasantly surprised that it arrived so quickly. After putting it together I was left with a very small screw, and two connectors that are female on one end and a push-fit connector on the other, there is no indication in the instructions what they are used for? The unit is a replacement for a high-end Nilfisk Alto unit which I have had for a good number of years, but it has been finally given up and I cannot find anyone to repair it. I am not comparing like for like here as the Nilfisk is brass and heavy plastic Whereas impression I get from the Norse is a lot lighter, and I am a bit concerned in respect of the water inlet connection that looks quite flimsy. The unit was used to clean a large area of lock block paved driveway that was very dirty with considerable growth. The first section was cleaned with the Nilfisk unit until it gave up and the Norse unit was used for the remainder. At first it was quite good quite good but I found that the unit appears to have two speeds. When first starting full pressure so no problems but if you stop for any reason and restart quickly the unit runs at a slower speed and pressure. Over the following two weeks the remaining area of lock block was jet washed and the Norse operated well and without major problems, except when the machine is stopped as I said and it has to be left it has to be left for about 10 minutes to get full pressure start up. If you lock the trigger it will run on full no problem but if you stop then you need to wait about ten minutes as I said to get full pressure again. I can only say that I am pleased with the purchase and it's initial outing has proved that it is a capable unit and more robust than its initial impression gives. I would certainly recommend it to anyone considering the purchase of a Jet wash unit.
