Run the quick checks first, then continue to detailed diagnostics.
Dirty water pooling in the Qrevo Curv cleaning tray? Run one manual wash, reseat and rinse the dirty-water tank, clean the removable tray and filter, then check the app alert.
Qrevo Curv auto-empty silent or ineffective? Check app and DND settings, the 10% battery threshold, a real cleaning return, dust bag, brush cover, and accessible airflow path.
Qrevo Curv dock skipping mop washing? Test a manual cycle, confirm a mopping task started from the dock, and check the active map, both water tanks, tray and filter.

Quick answer: If your Dreame X40 Ultra is not charging, first confirm that the base station has power. Then unplug the station, clean the metal contacts on both the robot and dock with a dry cloth, check that both spring-loaded dock pins move freely, and let the robot dock itself.
