I've got an older electric Ryobi. It's ok, doesn't always go to full pressure for some reason, or takes a while to get there (air lock?)
The biggest annoyance is the stiff plastic hose, awkward to work with. Should check to see if it is replaceable, if I can sort the pressure situation
Well changed out the hose for a 50ft Flexzilla, much more flexible and the longer reach over the stock 25ft was handy
Undoing the gun and letting the water run for a minute got rid of the air locks
Hose was not cheap but it's like using a whole new washer
