The most common problem with cordless hand vacuums is damage from dirt and debris that enter through gaps in the motors or collection bags. Failing rechargers and weak batteries are also major problems that cordless hand vacuums face.
To protect the hand vacuum from becoming damaged by dirt and debris, ensure that the motor and collection bags are firmly mounted. Shaking off the dust from the filter after every use, regularly washing cloth filters or replacing paper filters, and examining the vacuum’s interior for any damage also help protect the hand vacuum from damage. Canned air or a larger vacuum can help clean and remove dust from the interiors of a hand vacuum. For routine maintenance and cleaning, refer to the unit’s manual.
