this vacuum is probably the biggest life saver for an apartment with two fluffy golden retrievers! it is incredibly lightweight and lasts long enough to vacuum our apartment, so we didn't need to purchase the additional battery. i also used it to vacuum baking soda off our mattress as i was doing a deep-clean on it and it was amazing how strong the suction was to pick up such small particles. this is our favorite vacuum by far and we are so glad we purchased it! i love all of the attachments and the optional wall mount.
