I purchased the WPX3400e, and I'm happy with its performance. I no longer worry about multiple trips to the gas station or adding oil to the motor. The motor emits no fumes, and its quieter than my previous gasoline-powered washer.
Not the cheapest model, but this unit has more actual sustained PSI than cheaper electric power washers. Build quality seems good overall. The only negative that I've run into thus far is that the high-pressure hoses scratch very easily on concrete surfaces (probably just cosmetic).
WE'RE READY TO USE, LIGHT WEIGHT, WE HAD A GAS WASHER IN THE PAST A LOT MORE MATINENCE AND HEAVY. AS WE ARE GETTING OLDER YOU TRY TO THINK AHEAD ON THESE THINGS.
