The commercial Sebo Evolution series comes in three variants: the 300, 350 and the 450 (the number denoting the width of the brushroll). They are all essentially the same machine with different width heads so cleaner head parts can differ. The spares on this page suit all variants unless stated otherwise. If you don’t see what you need on this page, or need to clarify fitment, please >>contact us<< to ask. We probably have it.
