Roborock QV 35S Robot Vacuum with Multifunctional Dock

The multifunctional dock washes the two spinning mops in a 3-stage dynamic cleaning process, dries them with cold air, empties the robot's dustbin into a disposable bag on a frequency you set in the app, and refills the robot's water tank mid-job. You still fill the clean water tank, empty the dirty water tank, rinse the cleaning tray as needed, and change the dust bag roughly every 7 weeks depending on use.

Two mop pads spin at up to 200 RPM to scrub dried spills and footprints, fed by an electric onboard tank with app-adjustable water flow, and SmartPlan can set water flow and suction per room automatically. Use cold water only and add only cleaning solution recommended by Roborock; other cleaners can foam and block the filter.

Yes. The robot retracts the mop mounts when it detects carpet so rugs are vacuumed with up to 10,000 Pa of suction without getting wet, and you can customize carpet cleaning strategies by carpet type in the app or mark a rug as a no-go zone. It crosses thresholds, doorsteps, and bumps up to 2 cm on its own. Very dark or shag carpet may still be refused, because the cliff sensors read it as a drop and cannot be disabled.

The mops are only washed if they were used, and the robot only returns for a mid-run wash when it started from the dock and the dock appears on the app map. If auto-emptying did not run, check that it is enabled in the app and that the dust container cover is installed. Auto-drying must be enabled and ends early if the robot leaves the dock; a steady red status light usually means the clean water tank needs refilling or reseating or the dirty water tank needs emptying.

A spiral all-rubber floating main brush and an arc-shaped anti-tangle side brush shed long hair and pet fur instead of winding it, and when the robot detects a large amount of hair it raises its auto-empty frequency so the bin does not overfill. Reactive Tech structured-light sensing steers around bowls, cords, and shoes in real time.

It connects to 2.4 GHz Wi-Fi only; 5 GHz is not supported, so choose the 2.4 GHz network on a dual-band router. Alexa, Google Assistant, and Siri Shortcuts are supported once the robot is linked in the Roborock app; for Alexa, say "Alexa, open robo rock" and then the command. If pairing fails, re-enter the password, allow location and local network permissions for the app, switch off any VPN, and avoid WEP security or special characters in the network name.

Clean the main brush every 2 weeks and replace it every 6 to 12 months; clean the side brush monthly and replace it every 3 to 6 months; rinse the washable filter every 2 weeks and replace it every 6 to 12 months; clean the mop cloths as needed and replace them every 1 to 3 months. Rinse the cleaning tray, dirty water tank, and sensors as needed and replace the dust bag roughly every 7 weeks. Operate only between 39 and 104 F (4 to 40 C), and not on floors with liquid or sticky residue.

The QV 35S raises suction to 10,000 Pa from 8,000 Pa on the QV 35A; both share the same dual spinning mops, mop lifting, 2 cm threshold crossing, and a dock that washes, cold-air dries, empties, and refills. Both map up to 4 floors: carry only the robot (not the dock) to another floor, create a new map there, and each map keeps its own rooms, zones, and no-go areas. If you only need auto-emptying without mop washing, the Q10 S5+ is the step down in the Roborock line.

Put the dock on a hard, level floor against a wall with at least 2.95 ft (0.9 m) of clearance in height, 1.31 ft (0.4 m) in width, and 3.94 ft (1.2 m) in front, and clear shoes, cords, and furniture legs from that area; Roborock lists obstacles near the dock as the usual reason the robot cannot dock, and a robot that was carried elsewhere rebuilds its map and may need to be placed on the dock by hand. Wipe the signal window on the front of the dock and the robot's front sensor, which it uses to line up. When an error occurs the robot's power light flashes red, the app shows a pop-up naming the cause, and a voice alert may sound; follow the prompt, which usually means clearing hair from the main brush or wheels, wiping the cliff sensors, or washing and fully drying the filter. If the same error keeps returning, contact Roborock support.
