I was surprised at how good this handheld vacuum works!  The suction power is fantastic!  It is only for small jobs and must be emptied as soon as you’re done.  There is no sealed container for dust.  The end part is where dust is held until emptying. There is a lip inside, so dust doesn’t come back out if tipped but it is possible.  The bag is super convenient because it holds attachments, charger and vacuum.  It’s perfect for toddler messes!
