Quick answer: Use the mopping system supplied with your model, fill its approved tank with the water specified in the manual, attach a clean damp mop pad, choose a conservative water-flow setting for the floor, and set carpet avoidance or lifting behavior before starting. In a standard onboard tank, do not add household cleaner or disinfectant unless your exact manual explicitly allows a compatible Roborock product.
Identify your mopping system
| System | Typical operation | Maintenance focus |
|---|---|---|
| Basic tank and detachable pad | Water wets a fixed or moving pad under the robot. | Fill correctly, wash pad after use, empty unused water where instructed. |
| Vibrating or lifting pad | Pad agitates and may lift over carpet. | Set carpet behavior; do not assume lifting makes every carpet safe. |
| Dual spinning pads with multifunction dock | Dock may wash, dry, and refill the robot. | Maintain water tanks, tray, dust bag, and pads. |
| Roller mop system | Roller is rinsed during use and serviced at the dock. | Follow the exact dock’s water, solution, roller, and tray directions. |
Set up a mopping run
- Vacuum a heavily soiled floor first; do not expect a wet pad to replace debris pickup.
- Remove loose cords, pet bowls, absorbent mats, and fragile items. Pick up small objects and deal with pet accidents manually.
- Fill the correct tank, then close its stopper or lid fully. Wipe off exterior drips before reinserting it.
- Wet the detachable mop pad and wring it until it is damp rather than dripping, if the manual calls for that step.
- Attach the pad or module securely, set the water-flow level, and configure no-mop zones or carpet rules.
- Begin with a supervised room so you can check water flow, carpet behavior, and dock return.
What cleaning solution can you use?
For a standard onboard water tank, the safe default is plain water. Roborock says it does not recommend adding cleaner to a water tank because bubbles can block the water outlet. The original Q7 manual also says not to use cleaning fluid or disinfectant in order to avoid tank corrosion.
Do not assume that rule bans every model-specific Roborock solution. Some newer docks have a separate solution cartridge and their manuals tell owners to use only Roborock-recommended solution in that cartridge. The rule is simple: use an additive only when the exact manual names the place, product, and ratio. Never pour a general-purpose floor cleaner into a robot’s tank because another Roborock model happens to accept solution elsewhere.
How to fill a Roborock Q7 water tank
For the original Q7 mopping module, Roborock’s manual says to remove the water-tank stopper, fill the tank with water, and close it. Dampen and wring the mop cloth, attach it along the slot, then slide the mopping module onto the back of the robot until it clicks. Adjust the water-flow switch before starting.
Do not confuse the Q7 with Q7 Max: Roborock says Q7 Max uses a combined dustbin and water tank. Check the label before removing a part or following an image from another Q7 guide.
Protect carpets and wood floors
Set no-mop zones or roll up rugs when your model does not reliably lift or remove its mop. A raised pad can reduce contact with some carpet, but it is not a reason to ignore a manufacturer’s carpet guidance. On wood or laminate, start on a low water setting and confirm the floor maker permits damp mopping.
After mopping
- Remove and wash a detachable pad after each use, then air dry it.
- Empty unused water if the manual directs it, especially before storage.
- Remove the module when the robot will not mop for an extended period, where the manual calls for that step.
- For a wash dock, empty dirty water, replenish clean water, inspect the tray, and replace the dust bag as needed.
A dirty pad can spread residue and restrict water flow. If the mop is almost dry, Roborock’s support advice includes checking water level and flow, cleaning or replacing the appropriate filter, washing the pad, and confirming the module is installed correctly.
Frequently asked questions
How does a Roborock mop work?
The method depends on the model. Basic models wet a detachable pad from an onboard tank, while higher-end models can use vibrating, spinning, or roller mop systems and a dock that washes and refills them.
What cleaning solution can I use in a Roborock?
Use plain water unless the exact manual explicitly permits a compatible Roborock solution or cartridge. Roborock warns that ordinary cleaners can create foam and block a water outlet, and some models prohibit disinfectant or other cleaning fluid.
How do I fill a Roborock Q7 water tank?
For the original Q7 mopping module, remove the tank stopper, fill the tank with water, close the stopper, dampen and wring the mop cloth, attach it, then slide the module into place until it clicks. Confirm the exact model because Q7 Max uses a combined dustbin and water tank.
Should I remove the Roborock mop after cleaning?
Yes for models whose manual directs it: wash and dry the mop pad after use, empty unused tank water as instructed, and remove the mopping module when not mopping to limit odor and moisture.
