Our old power washer gave out and we wanted a new one so I set out to research the best options. I quickly decided I didn't want an electric or battery power washer due to lower performance/power. I wanted one with PSI in the 2700-3400 range based on the jobs we would use it for (deck, fence, sidewalk, driveway, house and maybe cars). After researching it came down to a 2700psi or 3200psi Westinghouse or a Sampson power washer. Consumer Guides led me to the Sampson options as they raved about their quality, build level, durability and performance. The price was a little higher, but I wanted something I could rely on for years.
However, as I read customer reviews I was surprised at how many 1 star reviews there was for the Sampson model I was considering. Plus, the bad reviews were almost all consistent with a terrible Kohler engine and a pump that fell apart too soon. I know all products will have 1 star reviews (this Westinghouse did as well), but 8% 1 star reviews on the Sampson with every complaint pointing to the same two key parts (engine and pump), plus horrible customer service reviews when people tried to get a brand new or nearly new unit repaired were just more than I was willing to deal with. So, I chose the Westinghouse since the 1 star reviews were only about 2% and the 4 and 5 star reviews were much higher.
I did find that some people complained about the unit coming broken and not being able to return it to Amazon. However, Amazon was very clear that while you can't return the item you can get a refund or replacement if it comes broken. Some reviews had a broken/cracked gas tank or other shipping issues so I quickly decided that was not a worry for me and that I would pout it together and inspect it right away to make sure it didn't arrive broken or defective. It didn't and the assembly was quite easy with set up instructions and the parts each in their own bag that was labeled so you knew what bag/item to involve according to the instructions. Within 30 minutes I had the unit together and power washing.
I will say that after reading the reviews I found some great tips that we decided to follow. First, we went to Ace Hardware and purchased a connector with a 60 degree angle so that the garden water hose that brought water into the unit didn't rub or rest against the wheel. I agree that this is a design flaw as the input valve is in the back of the unit just inside the back left tire and instead of pointing back away from the power washer it points directly towards the right side of the unit and the right tire. After reading a couple other reviews that suggested getting a connector with a 45-90 angle we purchased one with a 60 degree angle so that the hose then angled backwards away from the power washer and didn't rest or touch the right tire at all. Others had expressed that not doing this had led to their garden hose getting a hole worn in it by resting on the tire as the unit vibrated.
The other suggestion that we did was to zip tie the power washer hose to the frame on the right handle right after where it attaches to the unit. Otherwise the hose comes out and runs right near the muffler that gets very hot. Customers had described how their hose touched the muffler and melted. A zip tie easily fixed this so that was not a concern at all and zip tying it didn't hinder the performance of the hose at all.
We washed our large (20x12) Trex deck and 14 stairs leading from the deck to the yard, plus a rectangle table, 6 chairs, deck rail and our Traeger grill/cover all in about 30 minutes. Everything looked great and you could see the dirt easily wash off after a full fall and winter of not being cleaned. My wife even tested it on the side of the house and the concrete by the bottom of the stairs and it did great there, too. It's great that it comes with multiple easy exchange nozzles that also clip right into the power washer tray by the handle so they don't get lost.
We've only used it once, but it worked great and was more powerful than our previous one. The 5 included nozzles will be able to handle every job we will want to do. So far we couldn't be happies and are glad we chose the Westinghouse model.
