    Abstract: A portable vacuum cleaner comprises a housing including a storage space and a lid coupled to the housing. The lid is moveable between an open position, in which access to the storage space is provided, and a closed position, in which access to the storage space is blocked. The vacuum cleaner further comprises a handle coupled to the housing, a suction source supported in the housing, a debris collection chamber in fluid communication with the suction source, and a first battery receptacle on the housing. The first battery receptacle is configured to selectively receive a first battery pack that is configured to provide power to the suction source.

    Abstract: A power tool includes a housing, a motor positioned within the housing, and an impulse assembly coupled to the motor to receive torque therefrom. The impulse assembly including a cylinder at least partially forming a chamber containing a hydraulic fluid, an anvil positioned at least partially within the chamber, and a hammer positioned at least partially within the chamber and engageable with the anvil for transferring rotational impacts to the anvil. The hammer includes a surface facing the anvil, a first through hole formed in the surface and a second through hole formed in the surface. The impulse assembly further includes a biasing member biasing the hammer towards the anvil. The flow of the hydraulic fluid through the first through hole varies as the hammer translates away from the anvil.
