The two AIRBELT D models are powerful, ultra-quiet, full-size canister vacuum cleaners with three on-board attachments, a giant 1.5-gallon bag, an unmatched 40-foot cord and 52-foot cleaning radius, protective rubber-coated wheels, a durable telescopic tube with quick-release connections, and a full bag or clog indicator. A unique tapered suction hose, with a 320⁰ rotating canister connection, increases their airflow velocity, minimizes clogs, and improves maneuverability. They also feature excellent filtration, a push-button cord rewinder, and a soft-foam bumper that protects the vacuum, furniture, and walls from scuffs and scratches.
