The three AIRBELT E models are powerful, ultra-quiet, lightweight, canister vacuum cleaners that offer innovative design, attractive contours, superb hospital-grade filtration, and an optimized internal airflow pathway that provides powerful suction performance. They feature a 37-foot cleaning radius, a large-capacity filter bag, three on-board attachments, rubber-coated wheels to protect floor surfaces, and a durable telescopic tube with quick-release connections. They also have a full bag or clog indicator, control-switch cord rewinder, and a soft-foam bumper that protects the vacuum, furniture, and walls from scuffs and scratches.
