An air suction gap between a perimeter wall surrounding the bedding tray and a perimeter side surface of the bedding tray, wherein the air suction gap extends around an entire perimeter of the bedding tray. Airflow openings included in the bedding tray drawing air through the bedding tray downward into the air channel. A blower unit carried by the base platform drawing air downward through the bedding tray and the air suction gap into the air channel, wherein the air suction gap channels air downward from around the entire perimeter of the bedding tray and into the air channel underneath the bedding tray so that debris is drawn down around the sides of the bedding tray.
