A few suggestions: I also had the leaking fitting that was mentioned by others, but when I found it hard to remove, I realized I must have cross-threaded it. The metal pipe that you attach a plastic fitting to that then attaches to the hose has sharp, machine-cut pipe threads. It's easy to get the plastic slightly cross-threaded so it's not straight enough to seal against the rubber washer. This fitting is only put on once, then it's left on. When it's on straight, it does not leak at all. The parts you can see such as the hoses, fittings, etc. seem to all be very high quality. I called Sun Joe and talked to the Tech before I bought the machine and was told it has an induction motor and a piston pump. The unit runs very smoothly, and is much quieter than I expected. The nozzles work good, and are easy to change. I found I was bending over just a bit when using the widest fan on some really tough mildew so I switched to the next nozzle so I could straighten up and get the same results. The Tech said to get "pressure washer soap" from a big box store as the wrong soap can harm the unit. The pressure washer soap @ HD has very fine print that says it is only for use with pressure washers that inject the soap at the nozzle. That soap is not for use in this machine as it runs the soap through the pump. (I called the Tech about this as they were not aware of the fine print.) The cleaning I've done so far, a car and its mag wheels, and 2 large concrete patio areas with 40+ years of Florida mildew were done quickly with no soap. If I ever do use soap, I think I'll just dump it on the surface from a bucket, then it can't harm the machine, and probably overall saves time because the machine does not then have to be flushed. Flush the air out of your garden hose so it is full of water before you attach it to the machine. Bleeding a hose full of air through the tiny nozzle takes longer, and if you don't get the air out and turn the motor on, you can ruin a really good machine. (The trigger on the wand is a manual valve. There is a pressure switch to stop the pump motor when you release the trigger, but if the machine is full of air, not water, the pressure won't build, and the motor won't stop until something melts.) The last bit of air is bled through the wand by pulling the trigger, but be sure the motor is not yet turned on. One last suggestion, get, or make a plug to go where the garden goes when the machine is not hooked up to the hose so mud daubers, or other little critters don't get stuff inside where it will go thru the pump. Happy spraying.
