Roborock S7 Max Ultra Robot Vacuum with RockDock® Ultra

No plumbing: the dock runs from a wall outlet and its own tanks. It empties the robot's dustbin into a 2.5 L bag that holds up to 7 weeks of debris, washes the VibraRise mop during and after runs, refills the robot's 200 ml water tank, dries the mop, washing sink, and water filter with a built-in drying module, and cleans its own base. The three containers on top are the dirty water tank, the clean water tank, and the dustbin, from left to right.

By default the robot returns to the dock every 20 minutes of mopping for a wash; you can change the interval on the wash settings page in the app or start a wash by holding the dock button while the robot is docked. Three washing modes are offered: Light for already-clean floors with less time and water, Balanced for typical homes, and Deep for occasional heavy cleaning with more water and a longer cycle. If washing results drop, reseat the mop cloth and switch to Deep.

Drying starts automatically after a mop wash or at the end of a cleanup, and the app offers 2, 3, or 4 hour drying durations under dock settings; you can also start drying manually or turn auto-drying off. If drying does not begin, check that auto-drying is enabled in the app and remember it only runs after mopping or mop washing, not after a vacuum-only run.

Yes. Ultrasonic carpet recognition detects carpet and the robot raises the VibraRise mop up to 5 mm, which Roborock recommends for short-pile carpet so rugs get vacuumed with 5,500 Pa of suction without getting damp; the app lets you pick other carpet modes if you prefer the robot to avoid rugs entirely. Very dark or shag carpet may still be refused, because the cliff sensors read it as a drop and cannot be disabled. PreciSense LiDAR stores separate maps for multiple floors (carry only the robot upstairs and create a new map), and in full or room cleanups the robot cleans along the floor direction to avoid scraping across floor seams.

The mop is only washed if it was used, and the robot only returns for washing when it started from the dock and the dock appears on the map; also check that the clean water tank is full and seated, the dirty tank is empty, and the water filter is installed. Auto-emptying will not trigger if the robot returned without cleaning or during the Do Not Disturb window, and a steady red dock light usually points to a missing tank or filter. Error 42 means the maintenance brush that scrubs the washing tray is jammed; clear it and retry.

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 Home, 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.

The 5200 mAh battery runs up to 180 minutes per charge, with automatic dock refills extending the mopping range to about 3,230 sq ft, and the robot recharges and resumes if needed. A full charge takes about 4 hours, 30 percent faster than earlier S7 models, and off-peak charging can shift recharging to cheaper hours. Roborock recommends leaving the robot on the dock whenever it is used at least weekly: once the battery is full only the main board draws power, so it does not shorten battery life. Off the dock the robot powers itself down after 24 hours of inactivity and has to be switched on by hand; if it will sit unused for several months, power it off.

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 weekly and replace it every 6 to 12 months; clean the VibraRise mop after each use and replace it every 3 to 6 months. Clean the dock's maintenance brush as needed and replace it every 6 to 12 months, rinse the water filter and dirty water tank as needed, and replace the dust bag when full, roughly every 7 weeks. Fill the clean water tank with cold water only and add nothing but Roborock's own floor cleaner, diluted 1:300, since other cleaners can foam, block the filter, or corrode parts. Operate only between 39 and 104 F (4 to 40 C).

Put the dock on a hard, level floor against a wall with at least 3.3 ft (1 m) of clearance in front of and above the RockDock Ultra, keep that area clear, and wipe the signal window on the front of the dock and the robot's front sensor; a robot that was carried elsewhere or just finished a spot clean rebuilds its map and may need to be placed on the dock by hand. Error 13 means dirty charging contacts: wipe them with a cloth dampened with rubbing alcohol, unplug the dock for two minutes, and try another outlet. Error 1 is a blocked LiDAR turret, Error 4 a dirty cliff sensor or dark carpet, Error 5 a jammed main brush, Error 7 jammed wheels, and Error 8 a trapped robot; clear the part named and restart. Error 10 or a filter blocked or wet alert means wash and fully dry the filter, Error 18 means tap the side of the robot to shake debris out of the fan, and an internal error calls for a factory reset before contacting Roborock support.
