ProTeam lists part 103806 as the 120 volt motor for the CX440 canister vacuum - reference 31 in the machine own parts list. When a CX440 stops pulling, runs hot, or will not spin up at all, this is the OEM component that returns it to service.
The CX400, CX420 and CX440 are ProTeam commercial canister vacuums - wheeled cylinder machines with a hose, wand and floor tool rather than a backpack harness. They are a legacy line: ProTeam has moved on, several CX consumables are listed as discontinued, and the current authorized ProTeam parts catalog no longer carries a CX model page. That is exactly why replacement parts for them are worth stocking. A CX canister with a sound tank and good filtration is a machine that owes nothing, and a single component swap keeps it earning.
Built for
- Cleaning contractors maintaining a small fleet of CX440 canisters in daily commercial use
- Vacuum repair shops that have taken a CX440 past the point where brush service will hold
- In-house facility techs restoring suction on a unit that is otherwise structurally sound
- Buildings holding a spare motor against a legacy platform with tightening parts supply
Motor, brushes, or bearing - check before you commit
The CX440 motor is a modular assembly, and ProTeam sells its wear components separately: motor brushes as part 103807, motor bearing as 103880 and motor gasket as 103877. That matters to your wallet. A machine that sparks at the commutator, loses power gradually or has simply run a very long time may need brushes rather than a complete motor. A machine that whines, rumbles or drags on spin-up is more likely a bearing. A motor that is seized, open-circuit, or has cooked its windings needs the full assembly. Diagnose in that order, and replace the gasket whenever the motor comes out - a new motor seated on a hardened gasket leaks air and gives back part of the suction you paid for.
Fitment note
ProTeam CX440 documentation names 103806 as the motor for that machine. A third-party listing elsewhere claims a different CX motor part number covers both the CX420 and the CX440; that claim conflicts with the manufacturer parts lists, which assign each model its own motor. Go by your own machine parts diagram, not by a cross-reference table.

Frequently asked questions
Do I need a whole motor or just the brushes?
ProTeam sells CX440 motor brushes as part 103807 separately from the complete motor. Gradual power loss and commutator sparking often point to brushes. A seized motor, an open winding or a burnt smell means the full assembly.
Is this a genuine ProTeam part?
Yes. 103806 is the manufacturer part number listed as the CX440 motor in ProTeam own parts documentation, and Discount Cleaning Products is an authorized ProTeam dealer.
Why are CX440 parts often special order?
The CX line is legacy and no longer appears in the current ProTeam catalog navigation, so several CX440 components are stocked as special order rather than shelf inventory across the industry.
Will the CX420 motor fit my CX440?
The manufacturer parts lists assign the two models different motor part numbers, even though one third-party listing claims a cross-fit. Treat that cross-fit claim as unverified and match the part number to your own machine diagram.
What else should I replace while the motor is out?
The motor gasket, part 103877, at minimum. Inspect the bearing and the filtration stack at the same time, since a motor that failed under a restricted airway will fail again if the restriction is still there.
Discount Cleaning Products is an authorized dealer for the brands we sell, so the parts on this page are genuine manufacturer components rather than look-alike substitutes. Our support is US based, and if you are unsure which part your machine takes, send us the model and serial number and we will work through the parts diagram with you before you order. We would rather spend five minutes getting the fitment right than have you return the wrong part.
