DEEBOT battery not charging on the dock
DIRECT ANSWER
COMMON CAUSES · RANKED
Power switch set to OFF MOST COMMON
DEEBOTs hide a physical switch under the top cover or on the underside — off means no charging and a very convincing "dead" robot. It is ECOVACS' first official check.
Dirty charging contacts or dock pins
The official manuals have you clean the robot's charging contacts and the dock pins — dust and oxide block the current path.
Dock unpowered or cord loose
ECOVACS' first step is the power cord at both the outlet and the back of the station — wall switches, smart plugs and half-seated plugs cut it silently.
Battery in deep discharge UNCOMMON
A completely drained pack needs re-activating — the official 500-series procedure docks the robot by hand for 3 minutes, removes it, and repeats three times before charging normally.
Battery worn out UNCOMMON
A robot that charges full but quits in minutes needs a replacement pack — aftermarket only for older DEEBOTs, so pick a reviewed brand and dispose of the old pack properly.
HOW TO FIX IT
Unplug the dock before cleaning its charging contacts, never bridge the two contacts with anything metallic, and never install a battery that is swollen, hot or leaking.
Confirm the power switch is ON
Open the top cover (or flip the robot on older models) and push the switch to the "I" position before anything else.
Verify dock power at both ends
Reseat the power cord in the outlet and in the back of the dock, then try another outlet if the dock shows no life.
Clean both sets of contacts
Unplug the dock and wipe the robot's charging contacts and the dock pins with a dry cloth until the metal is bright.
Dock by hand and watch the light
Place the robot on the dock; a voice prompt plays and the AUTO button flashes white while charging. Leave it 4-5 hours.
Reboot before blaming the battery
ECOVACS' current charging checklist says to long-press the power button to reboot, then dock the robot again. Do this after the outlet and contact checks, before buying a battery.
Re-activate a deeply discharged battery
Officially — dock the robot by hand, remove it after 3 minutes of charging, repeat three times, then charge normally. If it still plays dead, replace the battery or contact ECOVACS support.

Replacement battery — N79 family
ECOVACS does not sell N79 packs self-serve — the market is aftermarket only, so buy a known brand with real reviews. Switch the robot off before opening the screwed battery door, never fit a swollen or hot pack, and recycle the old one.

Replacement battery — OZMO 920 (3200mAh)
The OZMO 920 uses the original 14.8V 3200mAh pack — not the physically different 5200mAh OZMO 950 battery. Power off before opening the compartment, never use a swollen, hot or leaking pack, and recycle the old battery.

Replacement battery — OZMO 950 (5200mAh)
The OZMO 950 uses the original 14.4V 5200mAh pack — not the smaller OZMO 920 battery. Power off before opening the compartment, never use a swollen, hot or leaking pack, and recycle the old battery.
