Only had a few days but used this pressure washer to clean 200 square feet or so of paving stones covered with decades of dirt and moss. After a short learning curve I began to use it efficiently and watched the grime wash away. There was no doubt which area was cleaned. It was like night and day! This product seems sturdy is easy to set up and carry. This was my first time using a pressure washer so I spent time reviewing the safety and operating instructions. This is a powerful tool so don't skimp on safety. This tool requires grounded circuits. If you have an older home with ungrounded circuits it won't work . Minor problem: I could not attach garden hose because the mfgr had put an extra washer in the receptacle in addition to the screen. I had to remove the extra washer for the hose to correctly attach. I have many more pavers and garden wall to scour away the moss and am confident I have the right tool.
I am giving it 4 stars because, throughout the entire description, a maximum pressure of 2500 PSI is mentioned, but the nominal pressure "which is 2000 PSI" is never indicated. Had I known this, I would have bought a larger one.
