The SEBO Airbelt D4 Premium is a full-size canister vacuum built for long service, pairing a 1,250-watt motor with the ET-1 electric powerhead for carpet and a separate hard floor brush. Its sealed system uses SEBO's S-Class hospital-grade filtration rated to capture 99.97% of dust, pollen and pet allergens, which suits allergy and asthma households. A 40-foot cord gives about 52 feet of reach, and the soft-foam AIRBELT bumper and rubber-coated wheels protect walls and furniture. It is heavier and bulkier than bagless rivals, but owners of SEBO canisters tend to praise the quiet running, filtration and repairable build over years of use.

Owners rate the D4 Premium very highly, praising its quiet motor, strong filtration and sturdy construction. Complaints center on its weight and size rather than cleaning performance.
The SEBO Airbelt D4 Premium is a full-size canister vacuum with an ET-1 electric power head and a hard floor brush. It weighs 15.9 lbs, draws 1,250 watts and runs at 63 dB. The ET-1 is a commercial-grade power head that cleans carpets and hard floors and removes pet hair.
The sealed system uses S-Class Hospital-Grade Filtration, which captures 99.97% of dust, pollen and pet allergens. Filtration has three steps: a pre-motor filter, a three-layer AeraPure bag, and an S-class exhaust microfilter. A tightly sealed casing keeps dirty air from escaping through the seams.
The 40-foot cord gives a 52-foot cleaning reach, and a button rewinds it. The tapered suction hose rotates 320° at the canister connection to improve airflow and reduce clogs. A window indicator turns orange when the bag is full, the microfilter is dirty or there is a clog. If that continues, a thermal cut-off switch shuts down the motor.
