Most automatic pool cleaners on the market are expensive and require electric motors or auxiliary pumps to operate. This project analyzed a relatively inexpensive automatic pool vacuum that works with a pool's filtration system. The existing device does not efficiently make use of the available hydraulic pressure by which it derives both thrust and suction. This is evident when it fails to climb the slope of an in-ground pool or remove debris settled in its path. The goal of the project was to target design changes that will optimize the performance of the vacuum and build a prototype to test the theory. Computer models were developed to predict required suction to lift debris and thrust to propel the unit up an incline. The theory was verified through several experiments and the results were translated into changes in nozzle diameter and suction inlet parameters.
