This guide will provide instruction for how to replace the power control board. The battery life of the Shark UltraCyclone CH951 is 15 minutes per 6 hours of charging. If you notice that the vacuum does not turn on at all, or is not staying on while fully charged, you may need to replace the power switch.
Please note that you must remove the battery connection first, as dealing with electric components could be potentially hazardous. However, the entire battery does not need to be removed.
