Mating connectors enable a vacuum cleaner section to be releasably attached to a toolbox section. The connectors include a downward-facing tongue that fits in a corresponding horizontal slot. The tongue has a vertical slot that corresponds with a vertical flange adjacent the slot. An interacting tab and slot prevent the vacuum cleaner section from being removed from the toolbox section when a closeable top on the toolbox section is closed. The two sections attach in a position in which upright side walls on the vacuum cleaner section align with the upright sides on the toolbox section, and an extended horizontal work surface is formed by portions of the hinged top on the toolbox section and the vacuum cleaner section. A handle on the vacuum cleaner section can form part of the horizontal work surface, which has parallel lateral grooves with co-linear segments on opposite sides of a recessed channel. A wheeled version has a handle hinged to a mount and a pocket that encircles and supports the vacuum cleaner section. Another version has a handle that retracts into the recessed channel and is arranged to support the top against the ground when the top is fully open.

A retainer clip for retaining components on a shaft eliminates the need for a threaded shaft and a hex nut to retain the components on the shaft. The retaining clip includes a main body having a through hole for accommodating the shaft, a plurality of teeth for engaging the shaft and projecting radially inwardly from the main body and a plurality of spring members projecting in a direction transverse to the main body.

An electric motor brush subassembly includes a housing base, a housing cover, a brush, and a constant force spring. The brush is mounted between the housing base and the cover with the coil of the spring mounted adjacent to the outer end of the brush. The axis of the coil is disposed at a right angle with respect to the length of the brush and an unrolled spring segment extends along a side of the brush and is fixed in a slot in the cover. The spring exerts a force against the brush to bias the brush against the motor commutator.
