Amazon has Black+Decker's cordless hand vacuum on sale for just $44.99 today as part of its Gold Box deals of the day. This is the lowest price that this vacuum has ever sold for, and it normally is available for around $70. It can hold a charge for up to 18 months in standby and reviewers state that you can use it for around 60 minutes before you need to charge it again.

It only comes with one filter, so you'll want to grab a few extras to be able to swap them out regularly.
