I have have this vacuum charge for over 24 hour . I use it just in my room to clean up bird dander , feather and the odd crumb that end up on my floor . it literally clean for 5 minute . what be I go to vacuum in 5 minute ? it could at least keep the battery charge while have it plug in while use , but it do not even do that . I would hope there be just something wrong with the battery but it do not seem that way , so this be a terrible product . I do not know where these good review be come from . I guess the attachment be pretty nice .
