Below is an explanation of the two main types of pressure washer. Whilst bar pressure is important the overiding factor in cleaning power is the water flow rate. More water = better cleaning.Home & Garden (sometimes referred to as domestic, DIY or consumer).Lightweight, easily portable and designed for regular use in a domestic environment, these machines range in power to suit the size of your cleaning task. Models featuring ‘water cooled motor’ technology offer greater performance, and top of the range machines are often fully loaded with accessories. Xpert or Professional (sometimes referred to as commercial or industrial)Heavy duty, robust and designed for maximum durability, Xpert or Professional machines have higher pressure and flow ratings, enabling you to clean with far greater speed and efficiency. These machines are not readily available on the high street or in DIY superstores and often feature upgraded components throughoutJargon Buster:• Bar or PSI: Bar is the most common measure of pressure. PSI = bar x 14.5.• Bar (max): This is the pressure achieved when the machine is first turned on• Bar (rated) pressure: This is the operating water pressure of the machine.• Motor size (kW): Motor size indicates power providing the machine runs efficiently. • Flow Rate (l/h): Higher flow rates enable you to clean large areas or objects fasterDid You Know:Pressure Washers use up to 80% less water than garden hosepipes.Pressure Washers are not subject to hosepipe bans if used for safety reasons, or if a suction hose is used to pull water from a harvested source. i.e. not the water mains. They are also not subject to a ban if used for commercial reasons, for example to maintain cleanliness, hygiene or company image.Important things to remember when using your pressure washer:• Always use an RCD when using electrical products in connection with water.• Never use a non-return valve at the pressure washer connection to a hose pipe.• Never drive over or lay items on high pressure hoses to avoid damage.• Your water supply hose should be a min of several meters long and unwound from its reel.• If you are using an extension lead, check that it is rated at min of 13 amps and fully unwound from its reel.

Bought to replace a kew hobby 80, not a patch on the kew for build or performance, doubt it will last a fraction of the time. Plastic casing very poor, fits where it touches, tool holder poor. Much noisier than the kew, chemical holder useful and easy to refill.Cleaning performance passable for very light duty. Good range of accessories but extremely overpriced.
