9 . The base bottom for a vacuum cleaner of claim 1 , wherein the magnesium is die-cast.
10 . A vacuum cleaner base comprising:
a wheel mount adapted to receive a motor and at least two fastening points disposed in the wheel mount to fasten a motor to;
wherein the two fastening points, a motor shaft, and a load shaft driving a beater bar are substantially collinear.
11 . The vacuum cleaner base of claim 10 , wherein the two fastening points comprise two generally flat portions disposed on the wheel mount configured to receive a motor lock bracket.
12 . The vacuum cleaner base of claim 10 , further comprising a motor support bracket fixed to the at least two fastening points.
13 . The vacuum cleaner base of claim 10 , wherein the wheel mount comprises die-cast magnesium.
14 . The vacuum cleaner base of claim 10 , wherein the wheel mount includes a generally flat portion configured to receive a motor lock bracket.
15 . The vacuum cleaner base of claim 10 , wherein the wheel mount includes a receptacle configured to receive a latch disposed on a wheel hub.
16 . A vacuum cleaner comprising:
a motor that in operation generates a suction for the vacuum cleaner;
a housing having one or more structural support members having a thickness of less than or equal to about 0.75 mm to about 2.5 mm,
wherein at one structural support member is arranged in a weigh bearing relationship to the motor.
17 . The vacuum cleaner of claim 16 wherein the walls are formed from a material comprising magnesium.
18 . The vacuum cleaner of claim 16 wherein the one or more structural support members support the motor in operation.
19 . The vacuum cleaner of claim 16 wherein the one or more structural support members support a beater bar housing.
20 . The vacuum cleaner of claim 16 wherein the thickness is less than or equal to about 1 to about 2 mm.

22 . A vacuum cleaner, comprising:
a base comprising a first portion, a second portion connected to the first portion, and a plurality of wheels disposed on the first portion;
a dirt collection component to collect debris during vacuuming and configured to be connected to the base;
a motor disposed in the base; and
a path formed within the base for directing debris from a surface toward the dirt collection component,
wherein the first portion is formed substantially from magnesium and is adapted to receive the motor.
23 . A vacuum cleaner comprising:
a base comprising a support section that is formed substantially from magnesium;
a pair of back wheels that roll using bearings and are mounted on the base over at least a portion of the support section; and
a multipurpose bracket assembly that connects a vacuum handle, bag mount, and cord support,
wherein the multipurpose bracket assembly conveys a propelling applied to the vacuum handle to the vacuum base.
24 . The vacuum cleaner of claim 23 further comprising a volute air inlet disposed parallel to a beater bar housing.
25 . The vacuum cleaner of claim 23 further comprising a bag mount configured to allow substantially all of a filter bag to be filled below the bag mount.
