Important information
Instructions from the manual
Prepare the cleaning area3 steps
Tidy ground cables and loose items; move unstable, fragile, precious and dangerous items to prevent entanglement, impact, injury or damage.
In a raised area, always use a secure physical barrier to prevent falls.
Follow the robot along its whole first cleaning route and watch for problems before allowing later independent cleaning.
Position the charging
dock
Instructions from the manual
Position the charging dock8 steps
Place the charging dock level and flat against a wall.
Connect its power cable and tidy floor cables.
Choose an area with good WiFi coverage.
Allow at least 0.5 m (1.6 ft) on each side and more than 1.5 m (4.9 ft) in front.
The figure key labels its side clearances as more than 0.5 m; preserve that source distinction rather than rounding away the condition.
Keep the cable from hanging vertically where the robot could catch it and disconnect the dock.
The dock indicator is on when powered and off while the robot charges.
Avoid direct sunlight and keep the location beacon clear so the robot can return automatically.
Secure the charging dock
with the adhesive tape
Instructions from the manual
Secure the charging dock with tapeView

Slide the combo unit back into the robot until it clicks.
Wet the official Roborock mop cloth and wring until it stops dripping, then slide it along the cloth slot and stick it firmly in place.
Slide the mount forward under the robot until it clicks.
Clean the cloth after 60 minutes of mopping to maintain water flow and cleaning quality.
After the robot returns to the dock, press both mount latches and slide the mount backward to remove it.
Wash the cloth after every use and regularly empty unused tank water.
Remove the mount when not mopping; never use it on carpet.
Connect to the app
Instructions from the manual
