A pressure washer represents a technological and mechanical idea which is rather simple straight forward to understand. Inventors of washers had an idea to step-up water pressure from your ordinary hose pipe to a level was it could be used to carry out effective industrial and home projects. It is in this context that an electric pressure washer can be considered to be a machine that converts low pressure water into high pressure water. It has further capabilities such as releasing the high pressure water in a heated form and also mixed with detergents.
The most important and remarkable parts of any washer are namely the engine, the pump, pressure wand also known as lance, spray gun and the pressure washer nozzles. In most cases these are also serviceable parts that can be changed at one point or another in the life of the washer. Pressure washers also fall into two categories namely those that are powered by gas or gasoline in full and those powered by electricity.
The amount of water pressure with which washers operate is measured in pressure per square inch (PSI) at a certain rate of release measured in gallons of water per minute (GPM). This is very important information and forms the back-borne of understanding the different types of pressure washers and their purposes. In a home setting a pressure washer is very hand in cleaning your driveway, roof, deck, boat, car, bicycle ride on mower and grill. These are day to day chores that are made very easy by using a pressure washer.
On the other hand industrial pressure washers are used at construction sites for example to clean off heavy dirt, to strip paint off before a repainting job, to remove grease and so on. What determines which pressure washer is used for home or industrial use is the power of the machine measured in PSI and GPM already mentioned above. Washer machines with a PSI of 1500 and GPM of 1.3 are typically suitable for home chores. Washers of 2500 PSI to 4000 PSI and 2.5 GPM to 3.5 GPM are more suitable for industrial sites. These are usually powered by gasoline unlike electric powered home washers.
Heavy duty pressure washers also run on high horsepower engines such as Honda and Briggs and Stratton. They are affixed to carts and carry huge gasoline tanks that enables them to run non-stop for an entire day. They generally look less attractive in design and presentation than home washers which are covered in colorful well designed hard plastic material. Industrial high pressure washers are essentially not suitable for your day to day home use. They produce so strong a pressure which can damage windows, wood and other home items. Heavy duty pressure washers have been known to gouge wood. It is for this reason that some industrial and construction sites also have home pressure washers for use on sensitive and vulnerable materials.
A final consideration about pressure washers are the numerous washer reviews for both satisfied and disappointed individuals that fill internet forums and store review sections. These have a lot to tell us about specific pressure washers both home and industrial. Price alone should never be a consideration when looking into investing into a washer. The manufacturer is important, pressure washer parts & accessories availability and user friendliness of a given machine are also important.
