Rated 3 out of 5 by from Pump leaked oil in 2 hours of first use Bought this unit being an fan/owner of several of Stihl’s other products. Paid a little more than some similar spec’d models, but wanted a quality unit. I had an oil leak in the first 2 hours of use. I believe the leak came from the pump. My dealer replaced the unit, but I’m left with concerns for the long term durability of the pressure washer. I don’t put a lot of use on the washer and am concerned about another failure just out of warranty. My experience, as well as other reviews don’t inspire confidence that one expects with a premium priced product. Especially a Stihl product.

Rated 4 out of 5 by from Expensive but good I bought this product a few weeks ago. So far, it's done everything I needed. I wash my truck with it, first using a foam cannon, then switching to a 25 degree fan tip. I washed all my outdoor furniture with it, and got great results. I also purchased the rotary cleaner to wash my driveway, porch, and back decks. It was excellent for all of these. The rotary head makes quick work out of flat surfaces, getting the job done in half the time. The machine cranks on the first pull most times, never needing more than 2 or 3 pulls. The power is consistent, no back firing, the engine runs smooth and is quieter than others I've used. It's not as powerful as other pressure washers on the market at the same price point but is powerful enough for my needs. The 2.7 gpm seems to make a big difference in terms of cleaning power. That said, I have two negative things to say about this machine: it's expensive, and it's cumbersome. I was willing to pay the price for Stihl's name. This is my 5th piece of Stihl equipment, and I will always look to them first when purchasing a new piece of equipment. But it does hurt to fork out that much for a pressure washer to be used around the house. As far as it being cumbersome, it is very wide, making it extremely difficult to use on stairs. This could be helped with a longer hose, but after spending $$$ on the pressure washer and $$$ on the rotary cleaner, I just was not willing to spend any more. I'm counting on this product to last a long time. That is why I spent the $$$ on it. To anyone in the market, I can say that this machine will do the job around your home. If you plan on washing driveways and sidewalks, the rotary tool is a must. You can also use the rotary on wood surfaces, but it did remove some of the stain from my deck.

Rated 5 out of 5 by from Beyond Expectations What else is there to say? This machine is way beyond expectations. I had an electric power washer for the cars and tried it on the fence, worked okay but needed more power…so after researching I chose the Stihl Dirt Boss. I have a weed whacker from Stihl, blower, chainsaw and a lawn edger...now I have a Dirt Boss. This unit fires up within 2 pulls and is ready for work. Always ready and dependable. It does a tremendous job on cleaning off old stain and making the fence ready for new stain. I highly recommend the Dirt Boss for any residential homeowners and light commercial jobs. You will not regret this purchase in my opinion.
