3 Ways to Cut Your Robot Vacuum Energy Bill
- 🌱
Schedule cleaning during the day when solar panels are producing (if applicable) to offset the energy cost.
- 💡
Keep floors free of cables and small objects so the robot doesn't get stuck and waste battery on retries.
- ⚡
Use virtual wall barriers to limit the cleaning area to rooms that actually need it, reducing run time.
