Sometimes when looking at pressure cleaners you can find there is a large range to choose from. To choose the right model for your application is very important, therefore the more information you have when purchasing, the better.
The first thing to look at is the water flow (referred to as liters per minute or LPM) the machine pumps and this is very important. The more liters per minute gives an indication of the time it would take to do a job. As an example, you could compare the water flow from a garden hose as opposed to a fire hose. Therefore the time you want to take to do the job is governed by the liters per minute the pressure washer pumps.
The higher water flow has a better cleaning effect and end result because the water is the actual element that cleans. It is a common belief in the market that the bigger the pressure the better the machine is and the better cleaning performance is achieved, however this simply is not the case. A machine delivering 10 liters of water per minute at an operating pressure of 1600 PSI will clean much better and quicker and achieve a much better result than a machine delivering 7 liters a minute at 2000 PSI. So this goes to show the water flow rate is an integral element to consider when purchasing a pressure cleaner.
The second element to look at in combination with flow rate is the pressure which is needed to remove whatever it is you're cleaning e.g dirt, grease, mould. Whilst we've talked about flow rate being important, it is the combination of flow rate and pressure which gives you the results you are wanting. A pressure cleaner delivering a flowrate of 10 liters per minute at 1500 PSI will not clean as well as a pressure cleaner delivering 10 liters at 2000 PSI which is different again to a cleaner delivering a flowrate of 7 liters at 2000 PSI.
The next consideration is how much the pressure washer will be used. Will it be used to clean around the house, car or boat or will it be used in a business environment where it is used for 3 to 4 hours a day? This is important because when looking at the pressure cleaners there are a lot of differences in construction.
Most machines are manufactured using one of two types of motors. There is the brush motor and the induction motor. Brush motors are generally found in smaller machines which suit light application use and should only be used for small periods at a time. If you are looking to use a machine for heavy application, an induction motor is a must.
Pump construction is another that should be looked at closely. There are generally three different types of pump constructions found within the industry.
Constructions to consider are:
* Motor type and size e.g brush motor or induction motor
Brush motor for small domestic use
Induction motor for more heavier usage e.g large concrete areas and industrial use
* Pump construction
Fibre anti lime light domestic use
Alluminium heavier usage
Brass industrial
Be sure to buy the right machine for the right application not just on price.
