Here is a video of one of our surface cleaners cleaning a bit of concrete. The benefits of this type of equipment are speed, safety and consistency while cleaning flat surfaces. We also have a Landa Water jet surface cleaner, this unit retails for $1800 from Landa Northwest and worth every penny. Our customers rave about the quality of our cleaning and the consistency it brings with this type of equipment. The time it would take a homeowner to clean a driveway of this size is two days. Although in reality they will not get near the results. The most common complaint by consumers when using just a standard wand is zebra strips which is inconsistency when cleaning next to the concrete resulting in a striped pattern.
