BRUSH DRIVE SYSTEM
BRUSH DRIVE SYSTEM
The brush drive system on the MiniMAG Series comes in three versions. The disc type,
disc type with brush assist and the cylindrical type. Each one is different although they do
the same thing which is turn the scrub brush or scrub pad.
CYLINDRICAL
The cylindrical brush drive system consists of the
controller, 2 brush drive motors, 2 drive belts, 2
brush idlers and two scrub brushes. The brush-
es counter rotate and sweep debris into a hopper
as well as scrub the floor. “Will-Fit” brushes are
usually our of round and/or fit the driver or idler
poorly loosely and will bounce promoting bearing
and belt failure.
DISC
The disc brush drive system consists of the
controller, 1 or 2 brush drive motors, 1 or 2 brush
driver hubs and 1 or 2 scrub brushes or pad
holders. The drive hub is a “gimbaled” design
that helps compensate for irregularities of the
floor. Only original factory equipment brushes
should be used on this machine or premature
scrub motor failure may occur. “Will-Fit” brushes
are usually not concentric and promote bearing
failure.
DISC WITH BRUSH ASSIST
The disc brush drive system consists of the
brush relay, 1 brush drive motor, 1 brush driver
hub, a scrub brush or a pad holder and the brush
assist adjustment. The drive hub is a “gimbaled”
design that helps compensate for irregularities of
the floor. Only original factory equipment brush-
es should be used on this machine or premature
scrub motor failure may occur. “Will-Fit” brushes
are usually not concentric and promote bearing
failure.
