Daily Maintenance (1 Minute After Every Use)

Do these quick tasks after every auto-empty/cleaning cycle:

Empty Dirty Water Tank (30 seconds)

1. Remove dirty water tank from RockDock Ultra
2. Pour into toilet or sink
3. Quick rinse with water
4. Shake out excess water
5. Reinstall tank

Why Critical: Full dirty water prevents mop washing and causes overflow errors.

1. Glance at clean water tank
2. Should be at least 25% full
3. Refill if below 1/4 line
4. Use distilled water for best results

Why Critical: Empty water tank = dry mopping = poor performance.

Quick Visual Inspection (15 seconds)

1. Check if mop pads look extremely dirty
2. Look for error indicators on dock
3. Verify robot returned to dock successfully
4. Glance at brushes for obvious tangles

Why This Helps: Catches big problems immediately.

Common Questions

How often should I replace Roborock S8 Pro Ultra mop pads?

With daily mopping: every 2-3 months. With 3-4x weekly mopping: every 4-6 months. Replace when pads feel thin, have tears, or no longer absorb water well. Machine washable, but replace after 30-40 washes.

Can I use tap water or must I use distilled?

You CAN use tap water, but distilled is better. Tap water causes mineral buildup requiring monthly descaling. Distilled water = less maintenance, longer component life. Tap water okay if you descale monthly religiously.

Should I clean mop pads manually or let dock wash them?

Both! Let dock auto-wash after each clean (keeps pads fresh), but also manually rinse weekly and machine wash monthly for deep clean. Dock washing alone isn't enough long-term - manual cleaning extends pad life 2x.

How do I know when to replace the auto-empty dust bag?

App shows dust bag fullness indicator. Replace at 75-80% full. Don't wait for 100% - overfilled bags reduce suction and strain motor. With daily use, expect replacement every 4-7 weeks (15-20 bags/year).

Does Roborock S8 Pro Ultra need professional servicing?

Not required annually, but recommended every 18-24 months for warranty-safe deep clean. Professional service ($80-120) includes all consumables, internal cleaning, and calibration. DIY maintenance sufficient if you're thorough.

What's the lifespan of Roborock S8 Pro Ultra with proper maintenance?

4-5 years of excellent performance with religious maintenance. Without maintenance: 18-24 months before major repairs needed. Battery typically needs replacement at 18-30 months regardless. Main logic board and motors can last 5-7+ years.
