Embodiments of the invention provide a paddle wheel mechanism for a pool cleaner. The paddle wheel mechanism includes a housing with an internal flow area, a paddle wheel shaft supported by the housing, and a paddle wheel supported by the paddle wheel shaft. The paddle wheel includes a base extending along a base width and a plurality of paddle wheel blades extending from the base within the internal flow area. The plurality of paddle wheel blades include a first-type blade with a first blade portion having a first blade width, and a second-type blade with a second blade portion having a second blade width. The first blade width and the second blade width are each less than the base width, and the first-type and second-type blades are arranged on the base in an alternating manner.
