The Bissell® BG477 is a manual triple brush, turbo 31" sweeper for interior and exterior application. The two front brushes rotate in opposite directions, grabbing the debris directly in front of the sweeper, while the brush roller on the bottom picks up all the fine particles. The debris is then deposited into the large, easy to empty 13.2 gallon container. It requires no electricity or battery. Can be used in vestibules, pool areas, outdoor seating areas as well as banquet areas and indoor corridors. It picks up dry or wet leaves, mulch, aluminum cans, paper cups, cigarette butts, as well as fine dirt. Time and labor costs over manual sweeping are significant. It is lightweight, has a stand up design, and operates on a belt free system.
