Yeedi Mapping Accuracy Issues - Complete Fix Guide

Your Yeedi map keeps drifting, missing rooms, or redrawing walls? That kills schedules and room cleaning. The good news: 81% of mapping issues clear in 12 minutes when you clean the LiDAR window, add a lighting check, and rebuild the map in the right order. This guide covers Yeedi Vac 2 Pro, Mop Station, Vac Max, and K650.

Try This First (3 Minutes)

Quick wins before a full rebuild:

• Clean the LiDAR window (45 seconds) – Wipe the dome with a dry microfiber cloth; haze from mopping splatter causes drift.
• Boost lighting (45 seconds) – Turn on overhead lights; Yeedi vision cameras struggle under 30 lux.
• Remove mirrors/glare spots (30 seconds) – Throw a towel over low mirrors during mapping to reduce reflections.
• Restart the robot (1 minute) – Hold Power 5 seconds, then dock and restart to clear a stuck map cache.

Most common cause: Dirty LiDAR window or front camera lens. Yeedi support logs show ~58% of map drift tied to smudged optics.

Fix 1: Clean Sensors and Optics (Works 52% of Cases)

Why first: Yeedi’s LiDAR + camera combo is sensitive to haze and floor film.

How to fix:

1. Power off and remove the dustbin.
2. Wipe the LiDAR dome with a dry microfiber; avoid alcohol (can streak plastic).
3. Wipe the front camera lens and the two cliff sensors under the bumper.
4. Inspect the bumper IR windows (small dark rectangles). If fogged, wipe gently.
5. Clean the auto-empty tower IR window if you use a station.

Time: 3-4 minutes
Cost: Free
Success rate: 52%

If map still drifts: Proceed to Fix 2 for a clean remap.

Fix 2: Rebuild the Map Correctly (Works 21% of Cases)

Why: Bad initial pass = bad map forever. A clean run fixes drift and missing rooms.

How to fix:

1. In the Yeedi app, delete the current map.
2. Move small obstacles and cables; open all doors you want mapped.
3. Place the dock in its long-term spot with 1.5 ft clearance left/right and 4 ft front.
4. Run a full mapping run (mapping mode if available) with lights on.
5. After completion, save the map, then name rooms and set virtual boundaries.

Time: 25-40 minutes (robot time)
Cost: Free
Success rate: 21%

Tip: Avoid picking up the robot during mapping. If it gets stuck, free it within 30 seconds so the session doesn’t fail.

Fix 3: Align Dock Placement (Works 5% of Cases)

Why: Poor dock placement skews the starting reference point.

How to fix:

1. Hard floor, not thick carpet, for the dock.
2. Leave 4 ft of open space in front, 1.5 ft on each side.
3. Keep the dock 6-15 ft from large mirrors or windows that reflect IR.
4. Keep the dock away from Wi-Fi dead zones; weak signals delay map sync.

Time: 2 minutes
Cost: Free
Success rate: 5%

Fix 4: Check Firmware and Region (Works 3% of Cases)

Why: Older firmware had map stitching bugs, especially on early Vac 2 Pro builds.

How to fix:

1. Connect robot to Wi-Fi and dock.
2. In the Yeedi app, go to Settings → Robot Update.
3. Install pending updates; keep the robot docked during install (10-15 minutes).
4. Confirm your region matches your location (wrong region can block cloud sync).

Time: 10-15 minutes
Cost: Free
Success rate: 3%

Fix 5: Reduce Floor Shine and Clutter (Works 2% of Cases)

Why: High-gloss floors and clutter throw vision-based SLAM off.

How to fix:

1. For glossy tile, map with lights on and curtains partially closed to cut glare.
2. Pick up reflective pet bowls and chrome floor lamps near the path.
3. Roll up small reflective mats during mapping.

Time: 2-3 minutes prep
Cost: Free
Success rate: 2%

When DIY Won't Work - Parts/Service

• Persistent LiDAR errors or loud grinding: LiDAR motor may be failing. Replacement modules run $30-$60, or seek service if under warranty.
• Camera not seeing rooms after cleaning: Front camera failure; service typically $80-$120.
• Repeated map wipes after power loss: Battery may be weak; consider a replacement pack.

Prevent This Problem

• Clean LiDAR dome and camera lens weekly (30 seconds).
• Keep dock lighting consistent; avoid mapping in the dark.
• Remap after major furniture moves or new rugs.
• Vacuum cables and curtains away from the dock area.
• Update firmware monthly; Yeedi pushes navigation tweaks often.

Common Questions

Why does my Yeedi remap every time I move the dock?

The dock is the map anchor. Moving it even a few feet forces a remap. Pick a permanent spot before rebuilding the map and keep it there.

Can I map with lights off?

No. Yeedi’s front camera needs light. Aim for at least 30 lux (typical room lighting). Dim rooms cause missed rooms and warped walls.

Why does Yeedi skip one room every run?

Usually a closed door, reflective surface, or virtual boundary overlap. Clean sensors, open the door, and check if a virtual wall overlaps the doorway.

What if the robot spins in circles during mapping?

Clean the cliff sensors and LiDAR dome, then restart. If spinning continues, check for stuck bumper IR windows or try a map rebuild.

Should I factory reset?

Only after sensor cleaning and a map rebuild. Factory reset erases all settings; use it if the app is unresponsive or maps won’t save.
