This is a used motor bucket for older Sebo manufactured 360 models. 

Do a visual comparison to establish compatibility, check all photographs and pay attention to the shape from all angles. These are NOT the same as Sebo BS36 motor buckets. 

As a used item, it will be in perfectly serviceable condition, but will have scratches and visual blemishes, and will want cleaning. 

The models this fits are variously badged as Jeyes, Lever, Diversey, Ensign, Electronic 360, ISS, etc. 

This head will also fit brown Sebo HS2/HS360 and red Cleanfix 350 models.
