Abstract
A rechargeable cordless vacuum cleaner system comprises a hand held vacuum cleaner and a separable charger. The cleaner includes a circuit board assembly having first and second sets of contacts disposed for engagement to first and second sets of mating contacts of a battery pack and the charger. Both sets of contacts are spring loaded for resilient engagement to the mating contacts. A pocket portion is formed adjacent the set of contacts to the charger to avoid direct exposure of the contacts to an operator of the cleaner.
