Roborock Qrevo 2 Pro Troubleshooting: Error Codes, Dock, Mop Pads

Roborock Qrevo 2 Pro troubleshooting follows a fixed order: simple causes first, then Roborock's own fix for each error. There is no user manual for this model on Roborock's support page yet. Its troubleshooting entries and FAQs, plus Roborock's product page, are therefore the official guidance this guide follows.

Each fix starts with the quickest check and builds on what Roborock itself states. Where Roborock publishes nothing, the guide says so instead of guessing. That includes runtime per charge and replacement intervals for parts.

Charging, emptying, mop washing and drying all happen at the dock, so the checks begin there. Then move to the section that matches the symptom or error code. If a fault keeps coming back on a new unit, the warranty section explains when to stop and contact Roborock.

Roborock Qrevo 2 Pro troubleshooting: the dock comes first

Read the dock light before anything else. With the robot docked, an unlit indicator means the charging contacts meet and charging works. A lit one means the contacts are not connecting, which is the fault Roborock's error 13 entry describes.

First, nudge the robot on the dock until the light goes off. Next, check both sets of charging contacts for dust, stains or oxidation. Wipe them with a dry cloth or one lightly moistened with alcohol, or rub them gently with an eraser. Then push the power cable firmly into the dock and the wall outlet, and try another outlet if needed.

Placement comes next. Roborock wants the dock on a hard, flat floor and against a wall. Its support pages also ask for at least 1.6 feet (0.5 m) clear on each side and 4.9 feet (1.5 m) in front.

Roborock names three reasons a robot may struggle to return to its dock. The run started somewhere else, the robot hit an obstacle, or someone moved it by hand. Move the dock to a spot with that clearance, then clean the dock's front signal area and the robot's front sensor. The robot uses both to locate its dock.

Mop pads, carpets and Soaking Mode

If the pads stay fitted during a carpet run, check the app. Auto Mop Removal detaches the mop at the dock before carpet cleaning and reattaches it afterwards. Roborock notes that you have to enable it yourself.

If the pads stay in the dock after a carpet run instead, Roborock publishes no fix. The pads reattach at the dock, so its docking advice is the closest guidance. Start with the floor under the dock and the space around it. Then clean the dock's front signal area and the robot's front sensor.

Finally, dock the robot and confirm that the dock light goes out. If the pads still fail to reattach, contact Roborock Customer Support. On a new unit, repeated failures are a warranty matter.

For carpet itself, the app offers Carpet Boost+ for maximum suction and Deep Carpet Cleaning for a second, crisscross pass. Those two are the settings to try on long-pile rugs. With the pads still fitted, the mopping module lifts up to 0.591 inch, a figure from Roborock's own testing. Rugs with deeper pile call for Auto Mop Removal instead.

For pads that stay stained or smell, switch on Soaking Mode. The dock then soaks the mop for about 4 minutes before washing it. Rinse the one-piece cleaning tray as well, since it detaches for that job.

Maps, sensors and the rooms it misses

Error 1 concerns the laser unit the robot navigates by. Turn the robot on and watch that the unit spins. If it stays still, rotate it gently by hand, then restart the robot.

A map should appear horizontal or vertical in the app. If yours sits at an angle, Roborock points to dock placement. Move the dock to a spot with the clearance above. Failing that, switch Map Saving off and back on; the next clean then builds a new map.

Roborock traces most missed areas and odd cleaning paths to a dirty wall sensor, on the robot's right side. First, make sure nothing blocks the way into the missed area. Then wipe that sensor with a damp cloth and run another clean.

A zone clean can fail if the zone sits behind a door that stayed shut during mapping. Open the door and start a normal clean near it. Once the robot has found the open doorway, start the zone clean.

Error 4 involves the cliff sensors. Wipe them, and check that the robot is not on dark or shag carpet, which can trigger it.

Brushes, hair and the airflow errors

The DuoDivide main brush pairs two brushes that turn at a 10% speed difference. That difference pulls bundled hair apart in the central gap. Roborock's 0% hair tangling figure, though, comes from a lab test with 0.1 g of hair under controlled conditions.

Error 5 points at the main brush. Clear anything tangled around it, including inside its two mounting slots and at both ends. Then run the robot with Carpet mode enabled, which is Roborock's next step for this error.

The side brush turns backward on purpose as it enters a corner, then switches back as it leaves. A side brush spinning the other way in a corner is therefore normal, not a fault.

Airflow faults start at the filter. For error 9, check the side of the filter for its magnet, and replace the filter if there is none. For error 10, clean the filter, dry it thoroughly and refit it.

A "fan speed lowered" message calls for two checks: the strainer for a blockage, then a fresh filter. For error 18, Roborock says to clap the side of the robot several times to clear debris from the fan.

Wi-Fi setup and the Reset button

Check the network type first. The robot supports neither 5 GHz Wi-Fi nor WEP encryption. Join it to a 2.4 GHz network, and switch a router that uses WEP to WPA or WPA2.

If setup still fails, work down Roborock's list. Check the Wi-Fi password, and give the app location permission. On iOS 14 or later, allow Local Network access as well. When the app asks for a network, pick your home Wi-Fi rather than the robot's own.

Remove special characters such as !@#$ from the network name or password, as Roborock suggests. Turn off cellular data and any VPN on the phone, then reboot the robot and the router. If you know your router's settings well, Roborock also suggests setting its DNS to 8.8.8.8.

An internal error has its own fix: a system reset. Open the robot's top cover and press the Reset button, using the diagram in the app if needed. The reset restores factory defaults, including Wi-Fi and scheduled cleans, so keep it for that error.

Noise: what counts as normal

Roborock puts normal operation at around 65 dBA. That is similar to normal conversation, a washing machine or a dishwasher. Its FAQ gives 63 dB for Vac & Mop and as low as 54 dB for Mop Only.

Mop washing and drying run at about 56-57 dB. Emptying is the loud moment, rising to 70 dB for a few dozen seconds. By Roborock's yardstick, a robot as loud as a hair dryer or a busy street is abnormal.

To trace a new noise, test briefly after each step. First, run the robot without the main brush and its cover. If the noise stops, refit both with the cover's tabs in the housing slots. Next, remove the side brush and test, then do the same with the front wheel.

After that, turn the drive wheels by hand and listen. Clean the bin and filter, or drop to the lowest suction setting. Finally, run without the mop mount or in Vacuum Only mode. If the noise survives every step, contact Roborock support.

Repeat errors, the warranty and Roborock support

Most of Roborock's troubleshooting entries end with the same advice. If the problem continues, contact Roborock Customer Support. An error that returns after the listed fix is where Roborock Qrevo 2 Pro troubleshooting hands over to Roborock.

The Qrevo 2 Pro carries a 1-year limited warranty from Roborock. Repeated errors on a new unit belong with support inside that year, not with more home fixes. Until support replies, stick to the steps Roborock lists.

Roborock's US support answers email at support-us@roborock.com and promises a reply within 1 business day. The helpline, 1-855-960-4321, runs 24/7 and serves the US only. Roborock's Qrevo 2 Pro support page also has a request form that asks for your location and product model.

Before you get in touch, note the error number, when it appears and the steps already tried. Not every difference is a fault, though. Roborock says the laser unit's finish, matte or glossy, varies by production batch and does not affect how it works.

Upkeep and spare parts without a manual

Roborock publishes no replacement intervals for this model. Its support page has no manual yet, and no schedule appears for the brushes, filter or mop pads. Replace a part when it wears out, or when an error such as error 9 calls for a new filter.

Roborock does give two dock figures, both from its own testing. The dust bag can go up to 65 days without manual emptying. Roborock adds that this varies with the home, its cleanliness and cleaning habits. The cleaning tray's maintenance interval can reach up to 170 days under controlled conditions.

Four Roborock parts list the Qrevo 2 Pro as compatible. They are the side brush two-pack, rotating mop pads four-pack, washable filter two-pack and 1 L floor cleaning solution. For dust bags or a main brush, check with Roborock that a part fits this model.

Roborock's support pages warn that cleaning products in the water may block the filter. Its own floor cleaning solution, though, lists the Qrevo 2 Pro as compatible. Use that solution and nothing else, at the ratio printed on its bottle. For ratios and bottle sizes, see the Roborock cleaning solution guide.
