How vacuum cleaners are made
The first suction vacuum cleaners of 1901 were so large that one was pulled by horses and powered by a combustion engine.

The short version
Most parts of a vacuum cleaner arrive from subcontractors, but the big plastic pieces are usually injection molded on site. On the line, an upright model starts as a bare base. Workers drop in the beater bar and belt, latch on a steel plate, bolt on fan and motor, then snap the housing over them. Handle, hose and bag follow before inspection and boxing.
-
Mold the plastic parts
Pellets from a hopper melt in a heated vat and shoot into a two-part steel die under heat and pressure. Housings, wheels, bag fittings and clear dust canisters all come out this way, then wait in rolling bins. When enough are made, the die is swapped for the next part.
Goes in -
Make the rubberized parts
The flexible hose that carries dust from fan to bag and the bumper around the housing are also produced in the factory.
Goes in -
Check incoming subassemblies
Parts built by subcontractors to the maker's specifications are inspected on arrival and stored in bins that roll to the line. Motors are bench tested before they go in.
-
Seat the beater bar
An upright begins with a base of metal or molded plastic. A steel bar fitted with brushes drops into notches at the front. From the bar, a rubber belt runs around a guide to the motor pulley.
Goes in -
Latch the base plate
A steel plate with small rollers and openings for the brushes slots in under the belt and locks with a cam lever. Through those openings the brushes agitate the carpet and shake dirt loose.
Goes in -
Fit axle and wheels
An axle slides through a tunnel across the rear of the base. A release lever on one end lets the operator drop or lock the handle, and wheels lock onto both ends.
-
Bolt on fan and motor
The fan bolts to the base and the motor assembly sits on top. Workers connect the motor to the fan, the headlight and the cord, and screw in a bulb at the front.
Goes in -
Snap on the housing
A plastic top with its bumper already wrapped on closes over motor and fan. A clear panel in it lets the headlight shine through.
-
Attach handle and bag
Plastic fittings for bag and handle go on at the rear, and the flexible hose links the base to the bag support. Wiring through the handle reaches a switch near the top, and the long cord is connected. A cloth outer bag and a disposable paper bag finish the machine, along with decals.
Goes in -
Inspect the finished unit
Line workers and supervisors can reject anything along the way, and each machine gets a quality check at the end. Selected units are also switched on and run before packing.
-
Bag and box
The vacuum goes in a plastic bag and then a preprinted carton, with attachments and paperwork alongside. Cartons are sealed and stored for shipping.

Worth repeating
- To convince friends that suction beat blowing, Hubert Cecil Booth knelt in a restaurant, sucked on a chair's covering and spat the dirt into a hankie.
- Hubert Cecil Booth and David T. Kenney independently invented powered suction cleaners in 1901.
- The 1868 Whirlwind used a belt-driven fan cranked by hand.
