Executive Summary
When white marks, sticky residue, or water stains appear after cleaning with a robot vacuum, the cause cannot usually be determined by appearance alone. Possible factors include cleaning solution ratio, product-device compatibility, mop cloth or water tank condition, local water quality, and floor surface. The solution is to first stop adding more cleaning solution, then separately maintain the floor, mop cloth, water tank, and sensors.
Who This Is For
- Robot vacuum users experiencing white marks, sticky residue, or water stains on the floor
- Personnel responsible for device maintenance, after-sales troubleshooting, or cleaning solution selection
Who This Is Not For
- Users who need to address obvious damage such as floor blistering, discoloration, warping, or water ingress into the device—such cases should contact the floor or device after-sales department
- Users who expect to use a single additional cleaning agent to resolve issues across different devices and floor types
How to Proceed
- Stop adding more cleaning solution and record the product used, ratio, device model, and floor type.
- Test the floor surface in an inconspicuous area with a clean, slightly damp cloth. Once confirmed safe, wipe in sections and dry promptly.
- Disassemble and clean the mop cloth, dirty water tank, or cleaning tray according to the device manual. Allow washable parts to dry thoroughly.
- Maintain sensors and charging contacts with a dry cloth as per the manual; do not spray liquid directly.
- If marks reappear, verify whether the cleaning solution is approved for the device and whether it was added correctly.
B2B Specifications
When selecting B2B products, ask suppliers to provide the recommended ratio, pH range, foam test, dried residue evaluation, floor and seal material compatibility, and test conditions for the target device. Test results should specify the formulation batch, water conditions, floor sample, and device model.
Comparison
Wiping the floor with a slightly damp cloth:Suitable for a low-risk initial check, but must still follow floor care requirements.
Cleaning the mop cloth and water tank per the manual:Eliminates the impact of accumulated dirt on components. Specific disassembly steps and water temperature vary by model.
Adding white vinegar, baking soda, or other cleaning agents:May conflict with device or floor requirements; not recommended without first checking the relevant instructions.

Conclusion
When dealing with residue, first stop adding more cleaning solution, then handle the floor, mop cloth, water tank, and sensors separately according to the floor and device instructions. Do not determine the cause by the appearance of the marks alone, and do not directly add other chemical cleaning agents. If the issue persists after cleaning, record the conditions and contact the device, floor, or cleaning solution supplier for further verification.

Frequently asked questions
Are white marks always caused by too high a cleaning solution concentration?
+
Not necessarily. The ratio, product compatibility, mop cloth or water tank condition, local water quality, and floor surface can all affect the appearance. The cause cannot be determined by white marks alone.
How to handle sticky residue on the floor?
+
First test the floor in an inconspicuous area with a slightly damp cloth. Once the floor is confirmed safe, wipe in sections and dry promptly. Do not add other cleaning agents directly.
How to clean the dirty water tank and mop cloth?
+
Disassemble the parts according to the device manual. The manufacturer's instructions typically require emptying dirty water, rinsing the washable parts with clean water, and drying them, but the specific steps and water temperature should follow the model instructions.
Can sensors be wiped with a damp cloth?
+
Follow the device instructions. iRobot's maintenance page explicitly states not to spray water or cleaning liquid on sensors or openings, and recommends using a clean dry cloth for related contacts.
Can white vinegar or baking soda be used to remove residue?
+
It is not recommended to add directly to the robot's water tank or use on unverified floors. Some device manufacturers explicitly advise against mixing water with white vinegar; always follow device and floor instructions first.
How to reduce the likelihood of recurrence?
+
Use a cleaning solution approved for the device, follow the specified ratio or automatic dispensing method, and regularly clean the mop cloth, water tank, and cleaning tray.
