Abstract: A vacuum can include a housing having an inlet adapted to receive debris being vacuumed. A mounting bar can be fixedly coupled to the housing. A floor collector assembly can be rotatably disposed about a first axis defined by the mounting bar. The floor collector assembly can include a first debris-passing member coupled to the mounting bar, a second debris-passing member rotatably coupled to the first debris-passing member and a third debris-passing member removably coupled to the second debris-passing member. The first debris-passing member can define an opening. The floor collector assembly can be operable in a plurality of modes. In a first mode, the opening can be substantially perpendicular relative to a vacuumed surface. In a second mode, the second debris-passing member can be rotated relative to the first debris-passing member about a second axis such that the opening is at an acute angle relative to the vacuumed surface.

Abstract: A vacuum is provided with a removable filter tray that allows a user to access the filter without having to disassemble the vacuum. The filter can then be changed or cleaned and easily replaced without disassembly of the vacuum.

Abstract: A power pack charging system includes a one-way compatible charger arrangement for use with multiple power pack types. In another aspect of the present invention, both of the power pack types can be used in a first charger but only one of the power pack types can be charged in a second charger.

Abstract: An impact wrench having a speed limiting control circuit to allow an operator of the wrench to controllably limit the maximum speed of the wrench to a predetermined value when a trigger thereof is fully engaged. The impact wrench includes a manually adjustable speed limiting control protruding from an outer surface of the impact wrench which is conveniently manually adjustable. The speed limiting control is coupled to the wiper arm of a speed limiting potentiometer which is electrically coupled to a speed control circuit within the impact wrench. The speed limiting potentiometer limits the maximum speed of the motor of the impact wrench (and thus the maximum torque which can be generated by the impact wrench 10) to an operator selected percentage of the maximum motor speed which would otherwise be produced when the trigger is fully engaged.
