1. A pool cleaning robot for cleaning a pool, comprising:
a filtering unit for filtering fluid;
a housing that at least partially surrounds the filtering unit;
an impeller configured to induce fluid to pass through the filtering unit when rotated at a first direction;
a pump motor for rotating the impeller;
a drive system;
first interfacing elements that are configured to interface with the pool during at least a part of a cleaning process of the pool; and
at least one second interfacing element that extends outside a bottom of the housing without reaching a virtual plane defined by bottoms of at least two of the first interfacing elements; wherein a radius of each second interfacing element of the at least one second interfacing element is smaller than one fourth of a distance between the virtual plane and a center of the second interfacing element.
