Maintenance Schedule
| Task | Frequency |
|---|---|
| Empty dustbin (if no self-empty) | After each use |
| Clean sensors | Weekly |
| Clean brushes | Weekly |
| Wash/replace filters | Monthly |
| Check wheels | Monthly |
| Replace self-empty bag | Every 1-2 months |
| Replace filters | Every 3-6 months |
| Replace brushes | Every 6-12 months |
Weekly Maintenance
1. Clean Sensors
Dust on cliff and wall sensors causes navigation issues.
- Wipe cliff sensors (bottom) with dry cloth
- Clean front bumper sensors
- Wipe LiDAR turret (if equipped) with microfiber
- Clean charging contacts on robot and dock
2. Clean Brushes
Hair wraps around brushes and reduces performance.
- Remove main brush/extractors
- Cut away tangled hair with scissors
- Remove side brush and clear debris
- Check for damage to brush bristles/rubber
3. Check for Obstructions
- Clear any debris from suction inlet
- Check wheels spin freely
- Ensure nothing is stuck under the robot
Monthly Maintenance
1. Filter Care
- Washable filters: Rinse with water, air dry completely (24+ hours)
- HEPA filters: Tap out dust; replace when worn
- Never put wet filter back in robot
2. Deep Clean Dustbin
- Remove and empty completely
- Wash with water if bin is washable (check manual)
- Clean around bin seal
3. Mop Pad Maintenance (if equipped)
- Hand wash mop pads monthly (even with auto-wash dock)
- Replace pads every 2-3 months
- Check for wear and debris buildup
Signs You Need Maintenance
- Reduced suction: Clogged filter or brush
- Robot getting stuck: Dirty sensors
- Not cleaning well: Worn brushes or full bin
- Strange noises: Debris in wheels or brushes
- Battery dies quickly: Battery degradation (eventual replacement needed)
Replacement Part Costs
| Part | Typical Cost | Replace Every |
|---|---|---|
| Filters (set) | $15-25 | 3-6 months |
| Main brush | $15-30 | 6-12 months |
| Side brush (2-pack) | $10-15 | 3-6 months |
| Self-empty bags (3-pack) | $15-25 | As needed |
| Mop pads (2-pack) | $15-25 | 2-3 months |
Annual maintenance cost: $50-100 for filters, brushes, and bags.
Extending Robot Life
Best Practices:
- Run regularly (batteries prefer frequent use)
- Keep floor clear of small objects (coins, toys)
- Store in moderate temperatures
- Update firmware regularly
- Don’t ignore maintenance alerts in app
What Reduces Lifespan:
- Never emptying dustbin
- Running with clogged filter
- Ignoring tangled brushes
- Letting battery fully drain repeatedly
When to Replace vs Repair
| Issue | Fix or Replace? |
|---|---|
| Weak suction | Fix: Clean/replace filter and brushes |
| Short battery life | Fix: Replace battery ($50-100) |
| Navigation issues | Fix: Clean sensors, check for firmware update |
| Motor failure | Consider replacing (repair often $100+) |
| Multiple component failures | Replace robot |
Verdict
Most robot vacuum issues are preventable with regular maintenance. Weekly brush cleaning and monthly filter
care will keep your robot running for years.
Budget $50-100/year for replacement parts—far less than the cost of premature replacement.
