Our Verdict

SEBO Airbelt D4

SEBO AIRBELT K3 Premium

The SEBO Airbelt K3 Premium and the SEBO Airbelt D4 each have their advantages. They both offer excellent pet hair pickup, but the D4 outperforms the K3 on both hard floors and carpets. It has a longer range, and its much larger dustbag means fewer bag changes over time. The K3 is lighter, more maneuverable, and better suited to tighter spaces. For larger homes with multiple floor types and longer cleaning sessions, the D4 is the more capable machine. For smaller homes and apartments, the K3 is a practical choice.
