    Abstract: A housing for a handheld vacuum cleaner includes a suction opening, a cyclone chamber, and a helical passage. The suction opening is defined in the housing. The cyclone chamber is in fluid communication with the suction opening. The helical passage includes a first end, a second end, and at least one sidewall. The first end is in fluid communication with the suction opening. The second end is in fluid communication with the cyclone chamber. The at least one sidewall extends between the first end and the second end. The at least one sidewall separates the helical passage from the cyclone chamber.

    Abstract: A portable lighting system includes a housing with a lower surface, walls extending from the lower surface, and a cavity defined by the lower surface and the walls. The cavity is divided into a first space and a second space. A light body is coupled to the housing for movement between a first position, in which the light body encloses the first space, and a second position, in which the light body allows access to the first space. A battery is removably received in the second space.

    Abstract: A battery powered fan assembly includes a fan housing that at least partially defines an airflow chamber, a plurality of fan blades positioned within the airflow chamber, a motor operable to rotate the plurality of fan blades, a battery receptacle configured to receive a removably battery pack to power the motor, and a base assembly configured to be placed on a support surface. The base assembly includes a first frame segment coupled to the fan housing, a second frame segment pivotally coupled to the first frame segment, and a third frame segment pivotally coupled to the second frame segment. The base assembly is configured to be collapsed into a storage configuration in which each of the first, second, and third frame segments are folded onto each other and expanded to a first deployed configuration in which the fan housing is elevated above the support surface by a first height.
