Drive Track

A robotic pool cleaner drive track (or drive belt) is a continuous, flexible loop fitted along the outer sides of a track-driven robotic cleaner’s chassis. Positioned around the external drive wheels and rollers, it transfers mechanical power from the internal drive motor to the pool surface to propel and steer the unit. While common, not all robotic cleaners use tracks; some models rely on wheeled drive systems instead.

Function and Construction

The drive track provides the traction needed to move across the pool floor, climb vertical walls, scrub the waterline, and clear obstacles like main drains and steps. Track treads are designed to grip common Australian pool surfaces, including pebblecrete, fibreglass, vinyl liner, and tile.

Moulded from chemical- and UV-resistant polyurethane or synthetic rubber, the track works through a two-sided design:

• Internal Teeth: Moulded lugs on the inside mesh with the motor-driven drive wheel and idler rollers, pulling the track in a continuous loop as the motor turns.

• External Tread: Raised outer ridges maintain surface friction and, on many models, drive the front and rear scrubbing brushes via connected gears.

Common Wear Issues

Friction from rough surfaces (especially abrasive pebblecrete) and prolonged exposure to sanitised pool water or unbalanced chemistry gradually degrade the elastomer:

• Stretching: Tracks elongate under tension over time, becoming loose and prone to derailing off the rollers during turns or wall climbs.

• Slipping: Worn internal teeth stop meshing properly with the drive wheel, causing the motor cog to spin inside the track without moving the unit.

• Loss of Grip: As the outer tread wears smooth or hardens from chlorine and UV exposure, the cleaner loses traction, stalling on slopes or failing to climb walls.
