less than a year old , less than 5 charge and the charger go bad and probably it damage the battery . the vacuum do not last too long , five minute and the battery be drain . I want to buy another charger but it seem that it be a difficult charger to find . it be a 16vac ~ 150ma . -lrb- ac be alternate current and most place I go they sell dc or direct current . -rrb- I definitely would never recommend this hand vacuum .
