If your eufy robot vacuum won’t charge on its station, or the battery keeps running flat, these are the checks from eufy’s manuals.

What This Problem Means

The robot isn’t getting power from its station. The S1 Pro manual’s FAQ lists the causes as charging pins that are dirty or out of line, or a station without power; the other manuals send you to the eufy app for error fixes.

Common Symptoms

• The robot doesn’t charge when it is on the station
• The robot’s light is red for low battery
• The station’s light or screen stays off

Safe Checks You Can Try

1. Check the station has power

Every eufy manual except the S1 Pro’s says to keep the station plugged in at all times. When it has power, its light comes on (white on most models; on the Omni C20 the light ring in the clean water tank glows red until you fill the tank, and on the C30 and C30 Edge it turns red if the clean water tank is empty or a tank isn’t seated). On the S1 Pro the station’s screen lights up, and the manual’s FAQ says that if it doesn’t, the power cord isn’t plugged in properly.

2. Clean the charging pins

Wipe the charging contact pins on the robot and the station with a soft cloth. eufy’s maintenance tables for the X10 Pro Omni, E35, E28 and E25 say to do this once a month. For the S1 Pro, the manual says to use a damp cloth, and its FAQ suggests cleaning the pins on the robot and station with an alcohol wipe.

3. Seat the robot properly

Make sure the robot’s charging pins line up with the station’s. On the S2, X10 Pro Omni, E35, E28, E25, C28, C30 and C30 Edge, press the detachable base down firmly on both sides. The X10 Pro Omni, E28, E25, C28, C30 and C30 Edge manuals warn that the robot may not return to the station properly if it isn’t fitted correctly. On the S1 Pro, the manual’s FAQ says to check the screen doesn’t show that the robot is disconnected.

4. Check the power switch (Omni S1 Pro)

The S1 Pro has a power switch under its magnetic cover. If it is on O the robot is off: switch it to I.

5. Check for low power mode (Omni C28 and S1 Pro)

On the C28, holding Recharge for 14 seconds while the robot is on the station puts it into a low power mode, and its light flashes once a second. Hold Power for 2 seconds to exit.

On the S1 Pro, the manual’s low power modes turn off some or all of the robot’s lights, and two of them also turn off the station screen and water tank light. eufy says they end when the robot and station restart.

6. Allow for heat and charging time

The S1 Pro manual gives a charging temperature of 5-40°C. On the S2 and C28, eufy says that when the room is above 35°C the robot charges first, and the station dries the mop with room-temperature air until it is fully charged.

Charging takes about 4 hours on the S2, 3.6 hours on the S1 Pro (from 15%), 4 to 5 hours on the E35, 3.5 hours on the E28, E25 and C28, and under 5.5 hours on the C30 and C30 Edge.

Battery lights by model

The Omni S2 and S1 Pro manuals don’t have a charging light table. On the S1 Pro, the station screen shows a charging animation when the robot docks.
