3. Operating the Motor
The main roller brush motor operates automatically as part of your Ecovacs DEEBOT's cleaning cycle. Once correctly installed, it will engage when the vacuum is performing its cleaning tasks, rotating the main brush to sweep debris into the dustbin.
No direct user interaction is required for the motor's operation after installation.
4. Maintenance
Proper maintenance of the main brush area can extend the life of your motor and ensure optimal cleaning performance.
Recommended Maintenance:
- Regular Brush Cleaning: Periodically remove the main roller brush and clean any tangled hair, fibers, or debris. Excessive entanglement can put strain on the motor.
- Inspect Brush Bearings: Check the ends of the main brush for any debris accumulation around the bearings, which can impede smooth rotation.
- Dust Removal: Use a soft brush or compressed air to gently remove dust and debris from the motor area if accessible, ensuring not to damage any wiring.
- Avoid Moisture: Keep the motor and surrounding components dry. Moisture can cause electrical damage.
