RB 600 is rated 4.8 out of 5 by 26.
Rated 5 out of 5 by from I was sold because of a reason that is often overlooked... The Cart. I am an average Joe homeowner that did HOURS of research for a pressure washer to suit my needs. First, I looked at the engine. This Kohler engine is the COMMAND PRO CH270... and that’s a good thing. If you have researched Kohler engines then you know that Kohler makes another line of engines that doesn’t share the same positive reviews that the COMMAND line does. Once I realized I was good to go on the engine I then moved on to researching the pump.I couldn’t find the pump brand for the RB600 listed ANYWHERE on the internet or in the product manual I read before making my decision so I called Stihl and asked them for the pump manufacturers name. Well, the nice guy I was transferred to didn’t know the name and said, “I think that one is made in Italy” Ha! He was thinking this is an AR pump but it isn’t. The AR pump is on the RB800. I went down to the dealer, took pictures of the pump with my phone and started researching based on photos. This triplex pump is made by Mi-T-M. I started researching Mi-T-M pumps and felt comfortable with their quality. On a side note, researching pressure washer pumps will give you a headache. There are so many positive and negative reviews that it’s hard to sort through what’s important and what isn’t....But I digress Now that I felt comfortable with the engine and pump I then moved on to what actually made me choose this model over less expensive pressure washers. The cart. This cart is fantastic. It’s tall, easy to maneuver and rock solid. The handle folds down for compact storage as well. The large tires allowed me to roll the washer all over my grass with little to no effort.My previous homeowner pressure washers had hose attachments in areas and on angles that caused me to trip over the hoses when moving the cart from point A to point B. The RB600 solved this issue.It started on 1st or 2nd pull every time including when hot. The 3GPM was plenty of flow for washing my house yesterday. The 3200 PSI is enough for anything I will encounter at my house.... maybe a little too much in some cases but there is an ability to dial down the pressure. The 40ft hose is high quality and long enough for my needs. I did purchase the 33” lance and pivoting coupler to make washing the house a little easier. The ONLY question I still have is if this is a downstream chemical injector or not. I called Stihl and asked them and Stihl told me that it IS a downstream injector but the manual clearly states that the chemical will be mixed inside the pump.,. So which is it? If it is a downstream injector then what is the ratio? 8:1, 10:1, 16:1? If this is a typo in the manual then Stihl needs to change the manual to reflect that this is a downstream chemical injector and state the mixture ratio.

Rated 5 out of 5 by from Great for the job I use this for everyday and big jobs. I do everything from wash the cars, clean the driveway, to cleaning the limestone on my house. A+++ on all jobs.

Rated 5 out of 5 by from Great pressure washer This is a recent purchase for home use. The washer starts easily on the first or second pull. It restarts easily when hot. The washer has plenty of power. The first job was to wash 2,700 sq ft of driveway which it handled with ease. I tried using soap and it worked fine but wasn't needed for the concrete. The wand is easy to use and effective. I tend to bend over a little when using it so I wish it was a couple of inches longer so it would be more comfortable when in use for long periods of time.

Rated 5 out of 5 by from A great investment Let me preface this review by stating I’m not a professional, I bought the RB600 for home use because I care about the quality of the tools I purchase. My philosophy is to buy tools that I can pass on to my sons and this was no exception. I’ve had other pressure washers with comparable specs, but nothing compares to this unit.Let me get into the things I really like about this unit. It’s polished! This isn’t an after thought item created to capture market share, it’s a well crafted machine. Start with the frame, it’s thick tubular construction and large tires jump out at you when you first see this thing in person. I thought the black and yellow brand I had was well made, but this thing is robust. It shouts at you that it’s ready to work. The height of the handle is perfect, no bending over to move the unit. You have no idea how much of a difference that makes for a guy pushing fifty. The second thing that will stand out is the pump. When I bought my last washer I made sure I got a triplex pump, but the pump on this unit makes my last one look anemic. Again, it’s beefy, it’s obvious that it’s a good pump. Are there better pumps? I’m sure there are, but in this price range it’s a standout in my opinion. It has easy to access service points to add and drain the oil with a very large clear sight window to see the oil level.The next thing I would like to remark on is the vibration mitigation system. I haven’t seen much information on this so let me explain. The Koehler engine is mounted to a steel plate which in turn is mounted to the chassis, however it has big rubber spacers between the chassis and engine which make it essentially float. It’s brilliant! My black and yellow unit would vibrate all the way down the driveway, but the Stihl stays exactly where you park it. No more rubber skid marks on the driveway like my old unit.The wand is great too with the added free floating and lockable perpendicular handle. It’s so easy to switch hands and flip the handle over. This is a feature my last unit did not have and I’ll never get another gun without this feature. The hose is steel braided and quality. It’s only forty feet, but I realized that it’s easier to roll up than my old 75 foot hose. The bracket to hang the hose is hands down better than any other unit I’ve had. It’s in a logical place, does exactly what it’s supposed to do and the hose never falls off in transport.Finally let’s talk about performance. The Koehler engine never misses a beat. It never even hints at a struggle unlike my black and yellow unit with the Honda engine. Don’t get me wrong, I love Honda engines, in fact I prefer them, but my last unit seemed to struggle when it got going full stream. This Koehler doesn’t seem to have any trouble keeping up with the work load. It increases RPMs when I apply load and it slows down when I take away the load. There is no hesitation it works flawlessly in my opinion. My last unit would have times when I started to work after bleeding the air where it would just stop pushing out water. I had two of those units and they both did the same thing. I don’t know what that was, but I’m so glad this unit does not do that. I bleed the air, Fire it up, and it starts blasting away.I can not say enough about this machine. It’s everything I hope my last pressure washers would have been. It was hard for me to spend that kind of money for the Stihl, but I am so thankful I did because it’s exactly what I’ve come to expect from this brand.I wasn’t a Stihl snob until my other orange equipment started to wear out and I bought my first Stihl. My experience has been that Stihl will give me the peace of mind that I’m looking for with every purchase. That isn’t to say that there aren’t other great brands out there. I’m Polish which makes me stubborn and fiercely loyal. Stihl has earned my loyalty. I now have three Stihl machines and each was a marked improvement over the unit they replaced. Not just a little better, a lot better. I’d Like to think that in 10 years or so, my oldest son will have his first home and I can buy him his first Stihl to start him off right and continue this tradition.

Rated 5 out of 5 by from Another great Stihl product! Well designed and manufactured product. I previously owned a different manufacturer's pressure washer. The difference between that one and this one is night and day. This one is well thought out from the consumer's perspective, well designed, starts with the first pull, runs great and gets the job done!

Rated 5 out of 5 by from Great machine, easy to use. This is a great machine and is easy to use. Starts easy, runs evenly, no issues, and I have now used it 5 times. Well worth the cost.

Rated 5 out of 5 by from Fabulous pressure washer and easy to start Just bought this product this week. Used it to clean my tractor and both vehicles as well as my lawn mower. Fires up first pull every time, has great pressure, and is relatively quiet. Absolutely love it! Great assortment of nozzles with standard equipment.
