SEBO Airbelt D4 vs Airbelt E3 Premium

The SEBO Airbelt E3 Premium and the SEBO Airbelt D4 are both high-end canister vacuums, but the D4 is the better choice for most people. They share the same ET-1 powerhead, so pet hair pickup and carpet performance are essentially the same. The D4's advantages come from its larger size: it has a much longer cord that covers large rooms without switching outlets, and a bigger dirtbag that needs replacing less often. It also has notably better bare-floor debris pickup because of its Premium Parquet Floorhead. The E3's advantage is that its construction provides a better seal for particle filtration.
