Start with power and contact, then clean only as instructed
Check the powered base and the robot’s contact with it. Before cleaning or servicing, turn off all controls, then unplug. The manual’s charging-failure checks include removing foreign objects at the robot connector and using a soft dry cloth on dirty contacts. Do not turn a contact check into disassembly or an unsupported repair.
Separate no charging from no connection or no resume
For Wi-Fi setup failure, the separate requirement is a 2.4 GHz network. For recharge-and-resume, the function must be enabled in the app. Neither a network symptom nor an inactive resume setting proves that a charging component has failed.
If the relevant documented check does not resolve the issue, contact Dreame support. The manual prohibits modifications or attempted repairs beyond its instructions; this page does not provide a battery, cable or dock replacement diagnosis.

01X40 Ultra charges but does not resume cleaning; which setting should I check?
Recharge-and-resume must be enabled in the app. Check that setting first; this does not identify the cause of every failure to resume.
