Both Airbelt K models are powerful, ultra-quiet and will provide years of reliable use! They feature clever storage of three on-board attachments, a five-year parts and labor warranty, a full bag or clog indicator, a big .8-gallon bag, a 25-foot cord and 37-foot cleaning radius, rubber-coated wheels to protect floor surfaces, and a durable telescopic tube with quick-release connections. The soft Airbelt bumper that surrounds the canister housing protects the vacuum, furniture and walls from incurring scuffs and scratches during use. Users will also enjoy effortless control of cleaning heads that have 180° steering abilities and super low 3.5-inch horizontal cleaning profiles that easily fit under beds and furniture.
