Safety Information
WARNING
• For the purposes of recharging the battery, only use the detachable docking station roborock EWFD28HRR or EWFD29HRR provided with
this product.
• The product must be switched off, the robotic arm retracted in its compartment, and the plug removed from socket outlet before cleaning
or maintaining the product.
• In order to avoid a hazard due to inadvertent resetting of the thermal cut-out, this appliance must not be supplied through an external
switching device, such as a timer, or connected to a circuit that is regularly switched on and off by the utility.
• The docking station can only be used to charge the robotic vacuum cleaner equipped with a 14.4 V/6400 mAh (TYP) lithium-ion battery.
• To prevent injury, when the robotic arm is operating (including but not limited to extending, gripping, carrying, resetting, and retracting),
do not touch any part of the product espcially moving parts and exposed wiring with hands or any other body part, nor interfere with it
unnecessarily. Keep children and pets away from the product when the robotic arm is operating.
• Risk of personal injury. Sensors and controls shall only be serviced by a skilled person.
• Users shall be adequately instructed on the use of this robot.
• This robot shall be stored indoors only.
• Do not use on slopes.
• Remove cords, hard or sharp objects (such as nails and glass), and loose items from the floor. Also, relocate unstable, fragile, valuable, or
hazardous items (such as balls, scissors, knives, electrical appliances, medicines, toxic substances, glass, porcelain, liquid-filled containers,
and lit candles) to prevent injury or damage due to items becoming tangled in, struck by, dragged, knocked over, picked up, or dropped
upon pickup by the robot.
• Stop using the product, including the robotic arm, immediately if it is damaged in any way or cannot operate normally. Contact customer
service for assistance.
• The gripper can hold a rated load of 0.3 kg. Do not use it to pick up any objects weighing more than 0.3 kg, as this may cause risks such as
object dropping.
• The robotic arm can pick up light items, such as slippers.
• The A-weighted sound pressure level is below 70 dB(A).

medicines, toxic substances, glass,
porcelain, liquid-filled containers,
and lit candles) to prevent injury
or damage due to items becoming
tangled in, struck by, dragged,
knocked over, picked up, or dropped
upon pickup by the robot.
When using the robot in a raised
area (such as in a duplex apartment),
always use a physical security
barrier to prevent personal injury
or property damage caused by
accidental falls of the robot or the
object picked up by the robotic arm.

Notes:
• If the power cord hangs vertically to the ground, it
may be caught by the robot, causing the dock to be
moved or disconnected.
• The status indicator light is on when the dock is
powered on, and off when the robot is charging.
• The status indicator light turns red if an error occurs.
• Place the dock on a hard, flat floor away from fire,
heat, and water. Avoid narrow spaces or locations
where the robot may be suspended in the air.
• Placing the dock on a soft surface (carpet/mat)
may cause the dock to tilt and cause docking and
departing problems.
• Keep the dock away from direct sunlight or anything
that may block the dock location beacon, otherwise
the robot may fail to return to the dock.
• Do not use the dock without clean water tank, dirty
water tank, dust container cover, disposable dust bag,
cleaning solution cartridge, or cleaning tray module.
• Maintain the dock according to the Routine
Maintenance. Do not clean the dock power cord and
charging contacts with a wet cloth or tissue.
• All docks are subject to water-based tests before
leaving the factory. It is normal that a small amount of
water remains in the waterway of the dock.

Issue Solution
Unable to power on
• Battery low. Put the robot on the dock and charge it before use.
• Battery temperature too low or too high. Only use the robot within the range of 4-40°C
(39-104°F).
Unable to charge
• Dock not connected to power. Check whether both ends of the power cord are properly
connected.
• Poor contact. Clean the charging contacts of the dock and the robot.
• Check that the status indicator light is on.
Slow charging
• When used at high or low temperatures, the robot will automatically reduce its charging speed
to extend battery life.
• Charging contacts dirty. Wipe them with a soft, dry cloth.
Unable to return to dock
• Too many obstacles near the dock. Clear them up or move the dock to an open area.

Common Issues
016
Issue Solution
Does the robot need to be charged
for at least 16 hours for the first
three uses?
• No. Lithium-ion batteries have no memory effect. The robot can be used once fully charged.
The robot does not resume
cleaning after recharging
• Make sure that the robot is not in DND mode. DND mode will prevent auto top-up.
• If the robot is placed manually on the dock or sent to dock by pressing buttons, it will not be
able to resume cleaning.
The robot begins to miss certain
spots
• The wall sensor, cliff sensors, or carpet sensor may be dirty. Clean them with a soft, dry cloth.
Poor cleaning performance and/or
dust leakage
• The dustbin is full and needs emptying.
• The filter is blocked and needs cleaning.
• The main brush is tangled up. Clean the main brush.
No or little water during mopping • Use the mobile app to increase the water flow.
The robot cannot return to the
charging dock after spot cleaning
or when it has been moved
manually
• After spot cleaning or a significant position change, the robot will re-generate the map. If the
charging dock is too far away, it may not be able to return to recharge and must be placed on
the charging dock manually.
Scheduled cleaning is not working
• Keep the robot charged. Scheduled cleaning can only begin when the battery level is above
15%.
The status indicator light is steady
red
• Voltage error. Check that the local voltage meets the requirements listed on the dock.
• Check clean water tank placement or refill the tank as required.
• Check dirty water tank placement or empty the tank as required.
• Check that the cleaning tray module and cleaning tray filter have been correctly installed.
Reduced emptying performance or
unusual noise when emptying
• The main brush or main brush cover is not properly installed. Check and install in place.
• The filter, air duct, suction inlet, air inlet, dustbin or disposable dust bag is blocked. Clean to
remove blockages.
Reduced mop washing
performance
• The mop cloths are not attached properly. Stick them on the mounts flat in place.
• The floor is dirty. Change the mop washing mode to “Deep” in the app for better cleaning.

• The robot will not auto-empty after returning to the dock in DND mode. Adjust the cleaning
time or DND period, or start emptying manually.
• Auto-emptying will not be triggered if the robot is moved to the dock manually. Start emptying
manually.
Unable to wash the mop cloths
• The mop cloths will not be washed if not used.
• If the robot does not start from the dock or no dock is found on the app map, it will not return
to the dock for mop washing.
• Check clean water tank placement or refill the tank as required.
• Check dirty water tank placement or empty the tank as required.
• Check that the cleaning tray module and cleaning tray filter have been correctly installed.
