The AR Blue Clean 396 is a home & garden high pressure washer that is particularly suited for cleaning outdoor spaces around the home such as floors, walkways and stairs. We recommend the use of the handy Mini Patio accessory, which is supplied with the machine, for these types of surfaces. In fact, the instrument is ideal for cleaning large areas like these and thoroughly removing dirt. For an even better result, we recommend that a detergent suitable for high pressure washers and for the surface to be cleaned be used.
