Robot Mop Troubleshooting: Dry Pads, Streaks, Leaks and Fit
Short answer
This hub links to guides on water delivery, leaks, streaks, pads and odors, and compares setup, maintenance and troubleshooting instructions by model. As a precaution, stop using a leaking robot.
Troubleshooting guides by symptom
As a precaution, record the robot and dock model names, the symptom, and any light pattern or error text before consulting a linked guide. As a precaution, check the model labels against the model named in each comparison row.
| Observed symptom | Related guide |
|---|---|
| Pad stays dry after a mopping job | No water delivery |
| Standing water or dripping | Puddles and leaks |
| Haze or dirty trails after drying | Streaks |
| Cloth falls off, folds or stays dirty | Pad problems |
| Whole room is omitted | Mapping and room coverage |
| Burning smell | Safety route |
| Dock or station smells bad | Station odor |
| Pads or roller not spinning | Pads not spinning |
| Water tank not detected | Tank not detected |
As a precaution, do not run a leaking robot while working through this table, and keep water away from power connections and dock plugs. As a precaution, if a burning smell appears, stop use and charging before opening the safety route.

Roborock
S5 Max. The manual recommends cleaning the cloth after 60 minutes of mopping to keep the cloth performing well. It also recommends removing and washing the cloth bracket and emptying the water tank frequently to prevent odors or mildew (S5 Max manual). When mopping starts immediately, dampen the cloth and squeeze it dry before attaching it to the bracket. Remove the bracket when the robot is not mopping.
S7. For the VibraRise cloth, wet it, squeeze out the excess water, slide it along the attachment slot and press it firmly in place (S7 manual). The manual asks you to clean the cloth and air-dry it, because a dirty cloth affects mopping performance. When the robot is not mopping, remove the cloth mount. When the mount is attached, the robot lifts it to clean carpeted areas, and the app lets you avoid carpeted areas. By default, No-Mop Zones activate while the mount is in place. The manual also warns that a finger placed between the mount and the tank risks injury.
ECOVACS
DEEBOT DDX57 with OMNI Station. The manual identifies the robot as DDX57 in its technical specifications (OMNI Station manual). Its troubleshooting entry for pad plates that do not rotate lists incorrect installation and foreign objects blocking the plates. The corresponding instructions are to install the plates correctly, with a click confirming the fit, or clear the foreign objects. In its operating notes, the manual advises against frequent removal of the washable pads. Its setup instructions specify filling the Clean Water Tank to the max water level and locking both tank covers tightly before use. The Station refills the robot’s tank automatically. The manual specifies the official ECOVACS cleaning solution.
iRobot
Roomba 100/1000 Combo. The pad-care article describes fitting and maintenance: press the bin release button to remove the bin, detach the pad plate, lightly dampen the pad and attach it to the plate, then reattach the plate to the bin. It specifies hand-washing in cold water, air-drying and avoiding machine washing (100/1000 pad). For the Roomba 100/1000 Series Combo group, the solution page specifies 2.5 caps of Braava Jet Fresh liquid in the empty water tank, or 3 caps with an AutoEmpty Dock, followed by filling the tank with water. It also permits plain water and warns against hot water. Its general warning for iRobot products says unauthorized solutions may void the warranty and cause corrosion (approved solutions).
Roomba Combo 10 Max with AutoWash Dock. iRobot warns that Bona hardwood and hard-surface floor cleaners cause excessive foaming that could send water onto the floor and affect it (approved solutions).
Information to keep before contacting support
As a precaution, write down the selected mode and the room before contacting support, and check pad and holder references against the model with the robot off. As a precaution, do not force an attachment latch.
As a precaution, check the model-specific instructions for pad preparation, attachment and cleaning liquid before a job. As a precaution, do not use a home recipe to test a blockage. As a precaution, keep a photo of any error text and note whether the symptom appears on one floor or across the home.
Precautions for repair and support
As a precaution, contact the manufacturer when the reservoir is cracked, a holder is damaged, a leak continues, or liquid reaches an electrical part. As a precaution, do not open a sealed water circuit, and do not push objects into valves or outlets.
As a precaution, follow the manufacturer’s model-specific instructions for reassembly and any post-repair test. As a precaution, report a recurring problem to the manufacturer and include photos of any gap around the attachment.
Safety limits
As a precaution, keep water away from a powered dock or plug, isolate the power before handling wet equipment, and stop when water reaches electrical parts. As a precaution, do not probe outlets. The puddles and leaks guide covers that symptom in more detail.
