In some configurations, the bracket arm may be formed integrally with a wheel caster housing operatively attached to a lower housing of the vacuum. This may be referred to as a caster bracket arm, which extends from the wheel caster housing, such that the hose is configured to sit within the caster bracket arm.

A battery pack, power tool, and power tool combination. The battery pack includes one or more battery cells, a first terminal electrically connected to the one or more battery cells, a high current power supply terminal, a power switch electrically connected between the one or more battery cells and the high current power supply terminal, and a low current power supply terminal electrically connected to the one or more battery cells. The first terminal and low current power supply terminal are operable to provide a substantially continuous low current to the power tool during a normal operating state of the battery pack. The battery pack also includes a controller operable to control the power switch to provide high current power through the high current power supply terminal in response to a call for power from the power tool.

The invention refers to an electrically operated mobile vacuum cleaner (2) for separating dust and particles from a suction flow (35), comprising an electric motor (38) and a turbine (40) for generating the suction flow (35), a vacuum cleaner housing (4, 6; 32) with a collection chamber (8) for collecting dust and particles separated from the suction flow (35), a battery cell (116) for providing the electric motor (38) with electric energy for its operation, wheels (20) assigned to the vacuum cleaner (2).

It is suggested that the battery cell (116) forms an integral part of an extractable battery pack (100a, 100b), the vacuum cleaner housing (4, 6; 32) comprises a recess (62) opening towards the environment and adapted to receive the battery pack (100a, 100b) in a direction (104) parallel to a longitudinal extension (136), the battery pack (100a, 100b) is equipped with first electrical contact elements (60; 60′) electrically connected to the battery cell (116), and the recess (62) is equipped with second electrical contact elements (64; 64′) electrically connected to the electric motor (38).

The contact elements (60, 64; 60, 64′) are adapted to automatically enter into a mutual electric contact upon insertion of the battery pack (100a, 100b) into the recess (62) for establishing an electric connection between the battery cell (116) and the electric motor (38) and for operation of the vacuum cleaner (2) by means of electric energy from the battery cell (116).

A filter for a vacuum cleaner includes a top having an open center, a bottom plate having an outermost edge, a center, an inside surface facing towards the top, an outside surface facing away from the top, and a catch extending from the inside surface annularly around the center, filter material being secured between the top and bottom plate. An adaptor for a filter cage or the filter cage itself includes a radial retention ring that engages the catch of the filter.

A modular vacuum system includes a first and second canister of different capacities that are configured to store debris. The modular vacuum system also includes first and second power heads that can be coupled to either the first or second canisters. The first and second power heads operate at different voltages that generate a first and second suction airflow. The first and second canisters store debris separated from the first and second suction airflow. The first and second canisters also store debris separated only from the first suction airflow.

A purge port system for clearing a clogged vacuum cleaner hose including a housing that is connected to, or part of, the vacuum cleaner. The housing includes housing openings. An insert engages with the housing. Openings are included on the insert. The housing and insert openings can receive an output and an input of a hose.

An extraction cleaner includes a supply tank, a recovery tank, a pump, a suction source, a base configured to support the suction source and the pump, an external hose, and a hose attachment assembly. The hose attachment assembly has a suction conduit extending from a suction inlet connected to the proximal end of the hose to a suction outlet in fluid communication with the recovery tank. The suction conduit is removable from the base with the hose. The hose attachment assembly also has a fluid coupling which is removable with the suction conduit. The fluid coupling extends from a coupling inlet in fluid communication with the pump to a coupling outlet coupled to a supply tube having one or more portions carried within the suction conduit. The proximal end of the hose is at least partially nested adjacent the base when the suction conduit is coupled to the base.
