Pressure Washing Guide

Lets discuss some of the different types of pressure washing units on the market. The direct drive unit, like sold at most of the big box stores, is cheaper but doesn't last as long as some of the other types of units. On a direct drive unit the pump turns at same same RPM's as the engine even though it could run at much less RPM. This coupled with the fact that the pump is also more susceptible to vibration from the engine lessens the longevity of the pump.

A belt driven unit is more expensive but will last for years and years if maintained regularly. The pump on a belt driven unit receives almost no vibration and operates at much less RPM's than the direct drive unit, therefore it will last much longer.

There is also gear reduction washers that try to achieve the same results as the belt drive but they aren't as reliable. If a gear tooth breaks you're in trouble, and there always seems to be problems with the gear case gasket leaking.

For most home owners that aren't going to be using their units everyday, the more affordable direct drive unit is probably the best choice.

Direct drive units are good. Thats all I have had since I have started and it has worked good. My next unit will be a belt driven though.
