Why does dust blow out the bottom when using the upholstery hose?

Answer: - Make sure to thoroughly vacuum the area where the machine is placed on the floor. The brush continues to rotate; therefore, will cause debris to move up through the hose. If you continue to experience difficulty with your machine, please contact BISSELL Consumer Services at 1-800-237-7691 Monday through Friday from 8 a.m. to 10 p.m. or Saturdays from 9 a.m. to 8 p.m. ET.
