Roborock Map Cleared or Reset Unexpectedly — Fix Guide

What Does This Error Mean?

Roborock maps reset when the dock is moved, when the robot starts from a location it does not recognise, or after a factory reset. Keeping the dock in a fixed position and letting the robot build its map over several full cleans gives a stable, persistent map.

Affected Models

Roborock S7 MaxV
Roborock S6 MaxV
Roborock Q7 Max
Roborock S8 Pro Ultra
Roborock S5 Max

Common Causes

Dock was moved from its original position — dock is the map's anchor point
Robot was started from a location too far from where the map expects it to be
Factory reset was performed (intentionally or accidentally)
Firmware update reset the map (rare, but has occurred in some updates)
Robot was offline when it cleaned and synced an outdated map when it came back online

How to Fix It

Fix the dock in a permanent position and do not move it. Place rubber feet under the dock or use tape to mark its exact position on the floor.

The dock is the origin point of the map. Every time the dock moves, the robot's saved map no longer matches the real world, forcing a rebuild.
Always start the robot from the dock, not from a position in the middle of the room.

If the robot starts far from the dock, it cannot confirm its position relative to the map and may start a new map rather than use the existing one.
In the Roborock app, enable 'Multi-Floor Map' if you have multiple floors. Each floor should have its own saved map, preventing one floor's clean from overwriting another's.

Without multi-floor support enabled, carrying the robot between floors triggers a map mismatch and can erase the map.
After any firmware update, check the app to see if the update changelog mentions map-related changes. If the update reset your map, it will need to be rebuilt from scratch.

Allow 3–5 complete, undisturbed cleaning sessions to build a new stable map after any reset.
Back up your map in the Roborock app: go to Map > Edit Map > Save Map (available on some models). This lets you restore a good map if it resets again.

The map backup feature is available on S7 series and later. It is not available on older models.

When to Call a Professional

Map resets are almost never a hardware issue. If maps reset consistently after every single clean despite a fixed dock, contact Roborock support — this may indicate a memory fault.

Frequently Asked Questions

How long does it take for a Roborock to build a full map?

Most Roborock models build a reasonable map after 1–2 complete cleaning sessions. By the 3rd or 4th full clean, the map is usually very accurate and all rooms are correctly identified. For best results, run 5 full undisturbed cleans before editing room labels or adding No-Go Zones.

Can I manually draw a map for my Roborock instead of letting it map itself?

No — Roborock does not support manual map drawing. The robot builds its map by physically driving through and LiDAR-scanning the space. You can edit the automatically-generated map (add room dividers, rename rooms, set No-Go Zones) but you cannot draw the floor plan from scratch.
