There is a simple fact that all pressure washers are NOT the same. The specifications might read the same and have similiar functions, but this does not mean they are equal in longevity and durability.
Just like cars you can have a Mini or a Rolls. Both are worlds apart on style, ability, longevity, durability and price, but you know what to expect. The same goes with pressure washers.
There are pressure cleaners on the market today that boast 4000 PSI and are offered for 600 dollars. You will find however that this will be false. You need to know what engine is needed and pump is needed to run that type of pressure without destroying the machine in the short run. We have all too often seen these machines come through our doors.
