DEEBOT won't connect to Wi-Fi

Severity: Info — the robot still cleans from its buttons — only app control and maps are offline N79/500/600OZMO 920/950/T5T8/N8/T9+T10/X1/T20/X2 OMNI

DIRECT ANSWER

A DEEBOT that won't pair is almost always fighting the Wi-Fi band or the phone's mobile data. DEEBOTs need a 2.4 GHz network, a slow-blinking Wi-Fi light, and a phone that stays off cellular during setup.

COMMON CAUSES · RANKED

1

5 GHz-only network or band steering MOST COMMON

ECOVACS documents 802.11 b/g/n 2.4 GHz support — a 5 GHz-only SSID gives the robot nothing to join. Split out a 2.4 GHz name or enable the router's combined mode.

2

Phone jumping to mobile data mid-setup

The robot's hotspot has no internet, so phones (Samsung's "Switch to mobile data" especially) bail out and the handover dies — error codes 10016 or 10503 in the app.

3

Robot not in network-setup mode

Officially, press RESET about 3 seconds until the musical tune plays and the Wi-Fi light flashes slowly — without that state the app searches for nothing.

4

Wrong password or exotic characters

ECOVACS asks for English letters and numbers in the Wi-Fi password; one typo or an emoji-grade symbol fails the join with error 10010/10018/10025.

5

Router features the robot can't pass UNCOMMON

Hidden SSIDs, web-login portals, VPN/proxy setups and out-of-range channels are all officially unsupported — simplify the network for the join.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Prepare the phone

Connect it to the 2.4 GHz home Wi-Fi, switch mobile data off, and give the ECOVACS HOME app its data and location permissions.

Put DEEBOT in setup mode

With the robot on, press the RESET button about 3 seconds until the tune plays and the Wi-Fi indicator blinks slowly.

Pair within 3 meters of the router

Keep robot, phone and router close together for the whole flow, and stay on the robot's ECOVACS_xxxx network until the progress bar passes 50%.

Re-enter the password by hand

Type it fresh with the show-password option on — only English letters and numbers.

Match any error code

If the app names a code, use it — 10010/10018/10025 is the join itself, 10016/10017 the phone-side timeout, 10503 the password handover, 10006/10011 an internet timeout, 10002 an app glitch.
