The upright that adjusts itself
The Automatic X7 and X8 are SEBO's flagship uprights, and the headline feature is exactly what the name says: the machine senses the floor surface and sets brush-roll height automatically. Move from tile to a low-pile runner to plush bedroom carpet and the head adapts without you touching a dial. It sounds like a convenience feature; in practice it's a cleaning feature, because most people never adjust height manually and therefore clean at the wrong setting most of the time.
Everything else is standard SEBO discipline: S-Class hospital-grade sealed filtration, a generous bag capacity that means fewer changes, a long cord, an instrument panel that reports problems, and a fully modular parts design. Motor and casing are covered for ten years, and the machine is built in Germany.
