I have a Greenworks 1600PSI (very similar competitor to Sun Joe) - that I have had for ~2 years now. Use it to clean a small patio (vinyl siding and roof and concrete floor) about 3-4x per year and it gets lent out regularly to friends and family quite regularly for whatever they are using it for, they don't quite disassemble it and drain it with the same care that I do but it still seems to be working just fine.
I will say these light duty electrics (not sure about the 2000+ PSI you are referencing) are good for smaller jobs and maybe easy house cleaning - I had another similar cheap electric when I had a small 1000 sq/ft stucco sided home in St. Petersburg, FL and it was perfect for washing the house 2x annually. I will say these are not quite the right tool to clean a typical medium-large dirty driveway as it would probably take forever even with a power head attachment.
