Benefits of technology

[0018]It is an advantage of the swimming pool cleaning vehicle in accordance with invention to overcome obstacles on the pool surface while operating without affecting the partial vacuum and water flow required at water inlet port.
[0019]It is another advantage of the swimming pool cleaning vehicle in accordance with invention to efficiently suck up dirt and debris into the swimming pool cleaning vehicle filter bag.

Problems solved by technology

Since swimming pool cleaner has to suck water in through this intake port, the intake port cannot have floor clearance which is too high.
If it is too high, debris set at swimming pool floor cannot be picked up by the limited partial vacuum and water flow generated by the water pump.
Swimming pools of such construction naturally have an uneven pool floor causing the typical swimming pool cleaner to become stuck or at least not run normally or cause extra drive motor wear caused because of slippage, which prevents the swimming pool cleaner from operating normally, and even running the risk of being hit and damaged, causing higher defective rate and higher maintenance cost.
One drawback to such a skirt is that it could be caught by uneven swimming pool floor.
On the other hand, a non-closed skirt cannot limit the water flow and therefore cannot generate enough partial vacuum and flow rate to bring debris and segregated dirt up to be filtered.

Embodiment Construction

[0027]To explain the objects and advantages of the swimming pool cleaning vehicle in accordance with the invention, the following description of the drawing and the exemplary embodiments are provided in detail. As will be appreciated by those skilled in the art, the exemplary embodiments are provided to explain the swimming pool cleaning vehicle in accordance with the invention in detail and not to be used to limit its scope.

[0028]The swimming pool cleaning vehicle in accordance with the invention improves the art by providing a swimming pool cleaner with concave bottom to ensure the vehicle can easily overcome obstacles found on the pool surface. Additionally, by locating the water intake port adjacent to the vehicle's drive means, either using wheels and / or rollers water with dirt and debris is most likely to be sucked into the swimming pool cleaner interior and filtered.
