The 350 was a groundbreaking upright vacuum cleaner and was the first ever to include many features that would later become standards on domestic machines such as a top release hose and hoister wand that had not been patented until SEBO produced their own.
SEBO's commercial upright vacuums consist of the 350, 360 and successor 370 models and the BS36/46 models dependent on floor head widths for the commercial market.
