Robot Vacuum Mapping Problems: Lost or Wrong Maps
Short answer
As a precaution, check your model's app and manual before deleting a map. The sources here name different causes for a lost map, including moving the robot or dock, a home layout change, a failed positioning and a long error state. Deleting a map on some eufy models also removes its zones.
Lost, wrong or misplaced maps: what the sources describe
A map problem can have several causes, and each source ties a lost map to different events. The sources in this guide name moving the robot or the charging dock, a change in the home layout, a failed positioning and a long error state. Deleting a map is a separate step with its own consequences, covered at the end. As a precaution, confirm your exact model and app version before you change a map setting, because the features below are listed per model.
When the map is lost
ECOVACS FAQ 475 on its Australian support site says a map is lost after a successful mapping run when the charging dock or the robot is moved, when the home changes significantly, or when positioning fails. A temporary map is then created before cleaning (Ecovacs FAQ 475). It suggests trying recovery by returning DEEBOT to the dock at its saved position. If that fails, the FAQ says to fully charge the robot and restart mapping from the dock, without following or interfering with it during cleaning.
The DEEBOT DDX57 manual describes the same kind of cause in its troubleshooting table. The Malfunction column reads “The map is lost.” The cause column says “The map might be lost if you move the robot while cleaning.” The solution column tells the owner to move the robot back to the Station, then find the saved map in Map Management in the ECOVACS HOME App and tap “Use This Map” (DEEBOT DDX57 manual). If the issue persists, the manual says to restart mapping.
For eufy’s RoboVac L70 Hybrid, the map-loss page lists these reasons for removal: deleting the map manually, resetting the robot, removing the robot from the eufy Clean app, moving the robot to a spot where the map no longer matches the layout, moving the charging base to a new location, and a robot stuck or in an error state for more than 10 minutes. It also requires adding at least one no-go or no-mop zone after mapping to retain the map (eufy L70 page).
Furniture maps, zones and layout changes
The DEEBOT DDX57 troubleshooting table lists “Unable to create the furniture map in the App.” in its Malfunction column Its cause column says moving DEEBOT while cleaning might cause the map to be lost. Its solution column says “During cleaning, do not move DEEBOT.” The mapping section of the same manual covers a robot that gets stuck in a narrow space under furniture. It suggests raising the furniture, covering the bottom of the furniture, or setting up a Virtual Boundary in the App (DEEBOT DDX57 manual).
The Roborock S7 manual links manual relocation and significant environmental changes to possible loss of saved No-Go Zones, No-Mop Zones, and Invisible Wall (Roborock S7 manual).
For iRobot’s i3/i4/i5 Roombas, the Smart Maps page says that major changes to the home layout, or a moved charging dock, mean the map must be deleted and remapped (iRobot Smart Maps page).
Relocation and the dock
ECOVACS FAQ 230 on its US support site says that moving a DEEBOT into a room with a saved map starts relocation, and that after a successful relocation the robot switches to the matching map (Ecovacs FAQ 230).
The Roborock Q5+ manual says that “After spot cleaning or a significant position change, the robot will re-generate the map.” It adds that if the charging dock is too far away, the robot may not be able to return to recharge and must be placed on the dock manually (Roborock Q5+ manual). Its error section also says to relocate the robot after resolving certain errors, then restart cleaning.
The iRobot page describes the charging station as a waypoint for i3/i4/i5 Roombas and as the point the robot uses to localize in the home. That is why a moved dock appears among the reasons to delete and remap.
Multi-floor and storage limits
US FAQ 230 describes a multi-floor function with storage for up to two fixed maps plus one temporary map. The Roborock Q5+ manual lists Multi-Map Management among its app features and notes that app details may change with updates. The eufy L70 Hybrid is designed to store a single map. An i3/i4/i5 Roomba supports one Smart Map. Mapping another floor requires deleting the existing map; cleaning another floor can use a Clean Everywhere job.
What changes by model
The table pairs each model or regional FAQ with its documented behavior.

Roborock Q5+ and S7
The Q5+ manual (model Q340RR) covers map regeneration, the dock-return limit and Multi-Map Management. The S7 manual ties No-Go Zones to Map Saving mode and warns that moving the robot by hand can remove them.
ECOVACS DEEBOT DDX57 and FAQs
The DDX57 manual’s troubleshooting table gives the lost-map and furniture-map rows above. FAQ 230 is US guidance dated March 4, 2021; FAQ 475 is Australian guidance dated March 10, 2023.
eufy RoboVac L70 Hybrid and X8 Pro
The L70 Hybrid page covers single-map storage, the causes of map loss and the zone removal that follows a deleted map. The X8 Pro page covers Revert Map and Delete, and gives the menu path.
iRobot i3/i4/i5 Roomba
The Smart Maps page covers the i3/i4/i5 family: one stored map, remapping after a layout or dock change, and a Clean Everywhere job for a second floor.
Deleting or resetting a map
Deleting a map can remove more than the map itself. On the RoboVac L70 Hybrid, the eufy page says removing the map also removes all zones, including No-go and No-mop zones, and that a new map must be created with the zones set up again (eufy L70 page). On the RoboVac X8 Pro, Revert Map restores the most recently edited version and keeps virtual boundaries and no-go zones, while Delete removes the map and its settings. The menu path is the gear icon, then Manage Map, then the three dots (eufy X8 Pro page). The Roborock S7 manual says a system reset restores cleaning schedules, WiFi and other settings to factory settings (Roborock S7 manual).
As a precaution, record your zones and virtual boundaries before changing a map, and check your model’s instructions for system resets and factory resets.
For a robot that cannot find its dock, see the return-to-dock guide. For other symptoms, start with the robot vacuum troubleshooting guide or the guide to resetting a robot vacuum.
