Carbon motor brushes are the part of a carpet extractor that wears out on a schedule rather than by accident. This is the black brush listed by Sandia as 10-1333 for the Super motor. Keeping a set on the shelf is what separates a fifteen minute motor service from a job cancelled because the vacuum motor quit on site.
Brushes are the sacrificial carbon blocks that carry current to the spinning armature. They shorten steadily with running hours, and once they get too short the motor loses power, sparks at the brush ports, and eventually stops. Published maintenance guidance for extractor vacuum motors puts brush replacement in the region of 1,000 to 1,200 running hours, and central vacuum parts suppliers advise replacing a brush once it has worn down to roughly 3/16 inch. Running past that point risks scoring the commutator, which turns a low-cost brush change into a motor replacement.

Matching the right brush
Sandia lists this brush family in several variants, separated by color and by motor: 10-1333 black, 10-1333-C cream for the XP-3, 10-1333-G green for the 2-stage Sniper motor, and 10-1333-O orange for the XP-3. Sandia does not publish an interchange chart, so match the brush to the motor actually fitted to your machine and to the color of the brush you are removing, rather than by machine model alone. Vacuum motors get replaced over a machine's working life, so what a machine shipped with is not always what is in it today.
Warranty
Sandia's published warranty policy covers parts, tools and accessories for 90 days. It excludes failures caused by improper maintenance or lack of maintenance, misapplication, misuse, tampering, or substitution of provided parts.
Frequently asked questions
How many brushes does a vacuum motor use?
A vacuum motor carries two brushes, one at each side of the motor tube. Replace them as a pair so they wear evenly, and check the packaged quantity against what your motor needs.
How do I know my brushes are worn?
The usual signs are falling suction, visible sparking at the brush caps and a motor that cuts out under load. Removing the brush cap with a flat screwdriver lets you measure the carbon that is left.
How often should motor brushes be changed?
Published guidance for extractor vacuum motors is roughly 1,000 to 1,200 running hours, but duty cycle decides it. Inspect on a schedule and replace at about 3/16 inch of remaining carbon.
Can the wrong brush damage the motor?
A brush that does not match the motor can seat badly and wear the commutator. Match the color and the Sandia part number to the brush you removed.
