A:AnswerSpare bags are not cheap. They are available from the mfg. but unless you need it to operate nearly dust free they are not required to be used. I’ve never use mine.
Batteries idk never researched them the stock one has always lasted enough time for my typical use cases of odd job clean up when finished with a project. Or when vacuuming out my cars.
Overall I’d say it’s a great little vacuum with better than expected performance.
