I've only used the ePX3100 once , but it works great, especially for the price paid. Hopefully it will last longer than the Ryobi did that cost double the price of the Westinghouse.
Purchased a few weeks ago. For its size, very impressed with power. Used so far to power wash car, truck, and 4 wheeler. Especially like the 4 wheels extra stability. Works as specified. Recommend
