The E1 model has telescopic tubes and suction hoses without integrated power cords, so they do not accommodate electric powerheads. Instead, the E1 Kombi comes with only a combination nozzle, with retractable bristles, to clean hard floors and rugs. Mid-size Canister Vacuum The AIRBELT E models are considered mid-size canister vacuums, which mean they are smaller, more compact machines that weigh about four pounds less than SEBO’s D-model canisters. Large-capacity Filter Bag The 3.5 litre filter bag is convenient and economical because fewer bag changes are needed and closing its built-in hygiene cap prevents dust from escaping during bag removal or disposal. Soft-start Feature The vacuum’s gradual power-up capability extends motor life. Control-switch Cord Rewinder The power cord rewinds by simply pressing a button. Three Protective, Rubber-coated Wheels, Mounted on Steel Axles The superb, rubber-coated castor-wheels glide easily and gently over all floor types, providing exceptional maneuverability and protection of floor surfaces. Full Bag or Clog Indicator When a full bag, a clog in the airflow pathway, or an excessively dirty microfilter is detected, an indicator window, located on the canister body, turns orange and an airflow bypass valve opens. This feature prevents overheating and motor damage from a lack of adequate airflow. Convenient Parking and Storage Aids After the work is done, the suction hose and telescopic tube, with parquet brush, turbo head, or combination nozzle, can be firmly stored on the canister’s underside or backside housing. Patented AIRBELT Bumper The soft, textile-covered, foam bumper protects furniture, walls, and the vacuum itself from incurring scratches and scuffs during use. It also diffuses exhaust air, which contributes to its ultra-quiet performance. Three-step, Hospital-grade Filtration It features a pre-motor filter, a three-layer Ultra Bag, an S-class, exhaust microfilter, and a tightly sealed casing.
