Issue 1: LiDAR Tower Not Spinning or Mapping Errors (43% of Cases)

Proscenic's Navigation: M8 Pro uses LDS LiDAR (360° laser scanner) on top. If LiDAR stops spinning or gets dusty, mapping fails.

Symptoms:

• LiDAR tower doesn't spin when powered on
• Robot creates incomplete or distorted maps
• "LiDAR sensor error" in app
• Navigation became random instead of systematic
• Bumps into walls it previously avoided

How to Fix:

1. Inspect LiDAR Tower:
   • Look at circular tower on top of robot
   • Should spin slowly when robot powered on (1-2 rotations/second)
   • If not spinning = motor issue or obstruction
2. Clean LiDAR Lens:
   • Power off robot
   • Wipe clear plastic lens on tower with dry microfiber cloth
   • Use circular motion, gentle pressure
   • Remove dust, fingerprints, or pet hair
3. Check for Obstructions:
   • Ensure nothing blocking tower rotation
   • Remove any stickers or debris on tower
4. Test LiDAR Spin:
   • Power on robot
   • Listen for soft humming (LiDAR motor)
   • Watch tower—should spin continuously
   • If spins then stops = overheating or motor failure
5. Reset Mapping:
   • ProscenicHome app → Settings → Map Management
   • Delete current map
   • Start new mapping cycle (let run 30+ minutes)
6. Check for Firmware Update:
   • App → Settings → About → Firmware Version
   • If update available, install (fixes LiDAR bugs)

Time: 8 minutes
Cost: Free
Success Rate: 43%
Difficulty: Easy

💡 Proscenic Tip: LiDAR motor can overheat if robot runs 2+ hours continuously. Let cool 15 minutes if tower stops mid-cycle.

If This Doesn't Work: Try Issue 2 - Wi-Fi connectivity

---

Issue 2: Won't Connect to ProscenicHome App (19% of Cases)

Proscenic Wi-Fi: Requires 2.4GHz Wi-Fi only (not 5GHz)—common issue with modern dual-band routers.

Symptoms:

• App says "Device Offline" but robot powers on
• Can't complete initial setup
• Connection lost after router change
• App works on one phone, not another

How to Fix:

1. Verify 2.4GHz Wi-Fi:
   • Proscenic M8 Pro only works with 2.4GHz networks
   • Check router settings—ensure 2.4GHz enabled
   • Connect phone to 2.4GHz network (not 5GHz)
2. Reset Robot Wi-Fi:
   • Hold Home and Recharge buttons simultaneously for 5 seconds
   • Hear voice: "Wi-Fi reset" or beep pattern
   • LiDAR tower should blink rapidly (pairing mode)
3. Re-add to ProscenicHome App:
   • Open ProscenicHome app
   • Tap "+" → Add Device → M8 Pro
   • Follow on-screen setup
   • Keep phone within 6 feet of robot during pairing
4. Check Router Settings:
   • Login to router admin panel

Common Questions

Is Proscenic M8 Pro as good as Roborock or Ecovacs?

Strengths: Similar LiDAR navigation, better value ($300-400 vs $600-800), good suction for price.
Weaknesses: Less durable (2-3 years vs 4-5 years), weaker app ecosystem, fewer smart features, limited service network.
Bottom Line: Excellent budget LiDAR option if you accept shorter lifespan and DIY repairs.

Why does my M8 Pro's LiDAR stop spinning after 1 hour?

Overheating protection. Proscenic's LiDAR motor runs hotter than premium brands (Roborock uses better cooling). Solution: Let robot cool 15 minutes, or clean LiDAR area to improve airflow. Some users report this issue worsens over time (motor aging).

Can I use Proscenic with Google Home or Alexa?

Yes. M8 Pro supports both. Setup: ProscenicHome app → Settings → Voice Control → Link Google/Alexa account. Common commands: "Start cleaning," "Return to dock," "Stop cleaning." Note: Room-specific commands require saved map.

How long do Proscenic batteries last?

Typical lifespan: 12-18 months with daily use (300-400 charge cycles). Budget battery cells degrade faster than premium brands (Roomba 2-3 years). Replacement batteries available on Amazon ($40-60)—installation requires 8 screws, moderate difficulty.

My M8 Pro creates distorted maps—how to fix?

Usually dirty LiDAR lens or overheating LiDAR motor. Fix: (1) Clean lens thoroughly, (2) Delete map and remapping in one session (don't interrupt), (3) Update firmware, (4) Ensure strong Wi-Fi signal during mapping. If still distorted after these steps, LiDAR motor may be failing.

Are Proscenic replacement parts available?

Yes, but limited. Amazon has filters ($12-18), brush rolls ($20-30), side brushes ($8-12), batteries ($40-60). Motors and LiDAR components harder to find—contact Proscenic directly. Aftermarket parts quality varies (read reviews carefully).
