I read the negative review for the vacuum and almost do not buy it , but I be glad I do . it work great and and will stay power up long enough to complete any job that I begin -- I would say about 10 minute . but that be what most cordless handheld vac do . the attachment be good to clean with and be handy at all time . I use this vac to clean one to two different room each day and have never have a problem . my house stay much cleaner and I have three cat to clean up after ! I keep it on charge when not in use and highly recommend this vac to use as it be design to be use which be not as a full-size vacuum .
