Incase you're wondering like I was. It comes with the battery, charger, wall mount, extra filter and attachments. Its exactly as described. A light weight cordless vacuum with good suction. In regards to the battery life you can clean an apartment with one charge. If you're cleaning every crack and crevice or you have a full size house buying a separate additional battery would be necessary. Its just not possible to have long battery life, good suction and a lightweight vacuum. Simply just vacuum your house and see if you need an additional battery later on.
