As others who have written reviews on this Cordless Vacuum by LIBERRWAY, it worked well up until recently. No matter how long it sits with the charger plugged in, it will work for less than a minute before the blue battery indicator light begins flashing.*UPDATE 05/02 - sent a message through to the seller by following the link to their Best Buy page and was responded to immediately asking for more detail, which I just sent. I was told not to worry, the vacuum is under warranty*UPDATE 05/04 - after a few messages back and forth detailing the issue, seller issued me a full refund. Adding a fourth star in recognition of the excellent and personal seller response.
