I bought this unit 2 months ago and have only had occasion to use it twice so far. I used it to clean my concrete patio and to clean some stubborn stains in a pool. both thimes it worked really well. assembly was easy.
My 20 year old power washer from another company died and I came across the ePX3100v. I used it yesterday to clean my deck and it hits all the key boxes. It's lighter, quieter and more powerful than my previous model. It's a light to medium duty power washer but that's all I need especially when working on stained wood which can be damaged by more powerful sprayers. One final observation - the turbo nozzle worked better than my previous model as it covers a few inches at a time while still retaining enough power and fast enough rotation to not miss spots.
