Sanitization chamber for a pool cleaner

A pool cleaner comprising:

• a housing, comprising at least one liquid inlet and a liquid outlet;
• a propulsion system for propelling the pool cleaner over a submerged surface of a pool;
• a suction system comprising a motorized pump, the suction system being configured to draw liquid from the pool through the at least one liquid inlet, and to expel the liquid back into the pool through the at least one liquid outlet;
• a filter configured to trap debris in the drawn liquid;
• a conduit to guide the liquid to flow from the pump to the liquid outlet, a wall of the conduit including one or a plurality of openings;
• and
• a sanitization chamber at least partially surrounding the conduit, the sanitization chamber including at least one interior port that is open to an interior of the housing such that a fraction of the liquid that is flowing from said at least one liquid inlet toward said at least one liquid outlet is diverted to flow through the chamber while a remainder of the liquid bypasses the sanitization chamber to flow directly to said at least one liquid outlet, an interior of the sanitization chamber being open to the conduit via said one or a plurality of openings to enable a flow of the liquid through the sanitization chamber between said one or a plurality of openings and said at least one interior port, the sanitization chamber configured to sanitize the liquid that is flowing through the sanitization chamber and to retard a flow rate of the liquid that is flowing through the sanitization chamber relative to a flow rate of the remainder of the liquid.
