I bought this for 2 reasons: save time and save my back. In these two areas, they completely meet my expectations. These two items alone make the product worth it.
There are some less important things that I am not as sure about. 1. The casters seem too small to smoothly handle things like brick pavers. 2. You have to use the power washer to rinse off the surface after cleaning because there is a lot of debris on the surface after cleaning. With tradition power washer this does not happen because you are rinsing as you go.
Some observations after using it include: 1. Do not use both extensions to attach it to the power washer. One provides much better control. 2. Longer in one direction and slower seems better than a bunch of back and forth motion.
The bottom line is this is very useful tool if you have a lot of sidewalks, patios, decks, etc.
Used on large concrete drive and sidewalk and very pleased with ease of use and quality of clean. It did amazing work with one pass and left minimal lines that were not noticeable after drying. The extension rods that were included were wonderful and allowed me to keep my back upright. The only reason I didn’t give 5 stars was because it did put some extra work load on my pressure washer, which was audible, and somehow caused some issues with it shutting off at times.
