1. A pool cleaning robot, comprising:
- a filter;
a first impeller;
a driving unit arranged to move the pool cleaning robot;
an external housing that comprises a first inlet and a first outlet;
a first pump motor arranged to rotate the first impeller;
wherein when the first pump motor rotates the first impeller rotates along a first rotational direction causes fluid to be drawn through the first inlet and causes a first portion of the fluid to be filtered by the filter to provide filtered fluid that exits through the first outlet of the housing;
wherein when the first pump motor rotates the first impeller rotates along a second rotational direction that is opposite to the first rotational direction, thereby performing a backwash operation of the filter.
