Cleaning drives, patios, decking, fencing, garden furniture etc., is made a lot easier when done with the help of a mains water fed pressure washer. Because the washer uses electricity and is working in a wet environment, the power should always be routed via a RCD (residual current device) circuit breaker. The pressure power of the washer is measured in bars, the higher the bar, the more poweful the washer. This range of washers extends from light-duty up to a high performance. The use and finished performance can be ehanced when using a patio brush attachment or chemical cleaning additives, these are available on several models but not all.
