Roborock QV 35A Robot Vacuum with Multifunctional Dock (Upgraded from Qrevo S)

The All-in-One Multifunctional Station washes the two spinning mops on a detachable scraper tray, dries them and the tray with cold air while rotating the mops periodically for even drying, empties the robot's dustbin into a disposable bag with a frequency it adjusts to how much debris it sees, and refills the robot's electric water tank. You still fill the clean water tank, empty the dirty water tank, pull and rinse the cleaning tray regularly, and change the dust bag about every 7 weeks depending on use.

Two mop modules rotate inward at 200 RPM with constant pressure on the floor, so dried spills get scrubbed rather than wiped. The robot carries an electric water tank, and you can set different water flow levels in the app to match tile, sealed hardwood, or laminate; SmartPlan can also choose modes for you. Use cold water only, and add only cleaning solution recommended by Roborock.

Yes. The robot retracts the mop mounts when it detects carpet and applies its carpet cleaning strategies, so rugs get vacuumed with up to 8,000 Pa of suction without getting damp; you can also mark a carpet as a no-go zone in the app if you would rather it skip the rug. It crosses thresholds and rug edges 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 map. If auto-emptying did not run, check that it is enabled in the app, that the dust container cover is installed, and that the robot did not come back without cleaning. Auto-drying must be enabled in the app and ends early if the robot leaves the dock; a steady red status light usually means the clean water tank needs refilling or reseating, the dirty tank needs emptying, or the cleaning tray is not installed.

The Dual Anti-Tangle System pairs an all-rubber main brush with a zero-tangle arc side brush that Roborock rates at a 0 percent hair tangling rate, so hair passes into the bin and then into the dock bag. Reactive Tech obstacle avoidance steers around bowls, toys, and shoes, and the dock raises its emptying frequency when it detects a lot of hair.

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. Amazon 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.

Yes, it supports up to 4 floors with PreciSense LiDAR, each map with its own rooms and no-go zones. Build the first map by starting the robot from the dock with map saving on and letting it finish a full cleanup and return to the dock on its own. For another floor, switch the map setting to multi-floor, tap create new map, and carry only the robot (not the dock) upstairs; it recognizes the saved map automatically on later runs.

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; clean the mop cloths as needed and replace them every 1 to 3 months. Rinse the cleaning tray, dirty water tank, and charging contacts as needed, and replace the dust bag as needed, roughly every 7 weeks. Leave the robot on the dock between runs and use off-peak charging in the app if you want recharging shifted to cheaper hours; operate only between 39 and 104 F (4 to 40 C).

Put the dock on a hard, level floor against a wall with about 2.9 ft (0.9 m) of clearance in height, 1.3 ft (0.4 m) in width, and 3.9 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.
