RB 400 Dirt Boss® is rated 4.5 out of 5 by 12.
Rated 4 out of 5 by from What One Expects of Stihl: Quality Two pulls. One to turnover. The second to start. A pleasure. Reliable.Pull feature might be better placed to allow pull start without tipping PW.But everything else is a joy to work with. Size, compactness, storage, performance (it goes without saying), and accessories - all top notch.The steel brace holding the axels appears to be thin or improperly supported - mine bent just a little.

Rated 5 out of 5 by from Great pressure washer everything I wanted and more I live in the Sierra Nevada mountains and have a few acres of cedar, pine and oak trees among others. The sap from the trees gets on everything. I had a less expensive power washer that did an ok job that I purchased when I lived in San Diego. It finally quit working. I have learned since moving to the mountains just pay a few extra dollars and get Still products. I own Still chain saws, pole saw, hedge trimmer, weed eater, backpack sprayers etc. I have never been disappointed. The power washer is just as good as my other Still products. It works perfectly, easy to start and with more than enough power to clean whatever comes its way.
