Shark vacuums are guaranteed to not need a replacement of either a battery or trash pouches. Even though they have this guarantee that you don't need to replace them, you still have to shake out the dust bin or trash bag so it doesn't become clogged. This can be an advantage because the vacuum usually remains lightweight and makes vacuuming less of a chore.
