Morphology
The meaning is directly and transparently derived from combining 'backpack' (a bag worn on the back) with 'vacuum' (a cleaning appliance): it denotes a vacuum cleaner designed to be worn like a backpack. This is a literal noun–noun compound following common composition patterns, so a B1 learner who knows both constituents should be able to infer the meaning.
Etymology
The noun backpack vacuum comes from a simple image: a small vacuum cleaner worn like a backpack on the cleaner's back. That's why today it means 'a small vacuum cleaner worn on the back', used for easy, portable cleaning.
