A vacuum cleaner includes a canister, a power head connected to a top of the canister, an inlet defined by one of the canister and the power head, an outlet defined by one of the canister and the power head, and a pre-filter bag disposed within the canister and fluidly connected between the inlet and the outlet. The power head includes an impeller assembly operable to generate airflow through the canister from the inlet to the outlet. The pre-filter bag includes an inlet port connected to the inlet, a radial inner wall, and a radial outer wall. The radial inner wall and the radial outer wall at least partially define an internal cavity and extend circumferentially about a central axis of the pre-filter bag such that the internal cavity forms a continuous, closed loop.

An attachment tool for a vacuum cleaning system includes a hollow body that extends from a first end to a second end and defines a flow path, and a conduit connector disposed at the second end of the body. The first end of the hollow body defines an inlet for receiving debris therethrough. The conduit connector includes an outer collar that defines a first inner engagement surface for connection to an outer diameter of a first vacuum conduit, and an inner collar that is concentric with the outer collar and defines a second inner engagement surface for connection to an outer diameter of a second vacuum conduit smaller than the outer diameter of the first vacuum conduit. The inner collar is axially offset from the outer collar towards the first end of the body.

A new electric broiler is disclosed. The broiler includes a housing having a cooking chamber, and a cooking surface in the housing. Upper and lower electrical heat sources are provided in the cooking chamber above and below the cooking surface. The lower heat source includes a removable heating module having an electric heating element and a quick connect/disconnect connector for quick electrical connection and disconnection of the electric heating element to and from a quick connect/disconnect connector on the housing. The broiler also includes a module holder on the housing for holding the removable heating module. The heating module is removable from the holder for quick replacement of the module.
