The Surface Cleaner SC 400 is an efficient rotating cleaner with a power regulation, making it easy to select the optimal pressure. It is equipped with an extra set of high intensive nozzles that offers more powerful cleaning for stubborn dirt. It is suitable for cleaning both vertical and horizontal larger surfaces such as patios, driveways, walls and terraces. Comes with an extension lance that also can be used with other accessories. Larger than the SC 300, this is suited to 300-400 series pressure washers.
