I bought the Greenworks 2300psi powerwasher based on various reviews. This would be my first time using this brand.Assembly was pretty much figure it out yourself because the diagrams and instructions were absolutely horrendous. Several different sized screws and no instruction on which size goes to what hole. I’m pretty good at figuring things out and you should be too.What really ticked me off was that my packet of screws was missing 1 of the 2 very important washers. The assembly could not be completed without this washer. So, in the car I go to Lowe’s for one single dang washer. I’m glad I brought the other one with me because of the hundreds of little washer drawers in that aisle, not a single one was the right size. I ended up having to buy a multi pack of 10 various sized washers just to get this taken care of. Greenworks basically lost any future purchases from me on this alone.I store this unit in my small storage closet when not in use. Right away I saw 2 serious design flaws. You cannot store this unit with the wheels flush against the wall because the wand handle sticks out too far when in the holster. Every inch matters when your storage closet is small like mine. So, I had to remove the wand from the holster to gain a few more inches of storage space.And speaking of the wand holster. What an absolute joke. Probably the lamest, with no thought put into this design holster at all. In a nutshell. It doesn’t work. The wand just falls out when rolling the machine through grass or sidewalk. One reviewer said he used velcro to make his work. Another reason to carefully research any future powerwasher purchase.Next, I finally got around to using this after having it a couple weeks. Initially I had problems with the motor coming on when I turned on the unit. Then, it would come on and and I would start powerwashing and it would cut off after maybe 15 seconds. The plug was fine and it was getting power so it was something to do with the machine itself. This happened a few times and I was already thinking that I was going to need to return this dud. Greenworks was quickly moving closer to the bottom of my list of brands to ever purchase again.Finally, the motor decided to cooperate and stay on after numerous tries and I was able to complete the job I set out to do in about 1 hour.One positive is the large power nozzle attachment. It worked wonders on the curb. This isn’t unique to Greenworks though as I noticed other brands also supply these in their nozzle attachments.Now that I have gotten past all the initial headaches I have had with my first Greenworks product, I was happy with the results. BTW, this unit is louder than the Sun Joe model I am replacing. It is advertised as quiet but I thought it was pretty loud.Now I will see if I have the same motor startup issues when I use it the next time in a few days. If I do, I will return it, update my review and go buy another brand.The photo attached is the slab of concrete I cleaned. I used an attachment (bought separately) that is a 15” large metal disc with castor wheels. It attaches to the wand and works very well with minimal effort. If you are doing large patios or driveways, I would highly recommend one of these. Don’t get the cheap plastic ones though. The heavier metal ones with wheels work better because they stay on the ground and don’t float like the lightweight plastic ones do.
