Roborock S8 MaxV Ultra with 8-in-1 RockDock® Ultra

This configuration runs from a wall outlet with self-contained tanks, so no plumbing is required. The dock empties the robot's dustbin into a bag good for up to 7 weeks, washes the mop with hot water up to 140 F, dries it with 140 F heated air, refills the robot's 100 ml tank from a 4 L clean water tank, doses detergent from a 580 ml cartridge that lasts over 3 months, cleans its own base, and charges 30 percent faster with off-peak support. You fill the clean tank, empty the dirty tank, top up detergent, and change the bag; the Refill and Drainage version of this listing removes the tank chores by plumbing the dock in.

You choose one of four carpet modes in the app. Rise lifts the mop up to 20 mm and stops water so the rug is vacuumed; Avoid keeps the robot off carpet entirely; Ignore is for homes without carpet or with mats that can be mopped; Cross drives over door mats without cleaning them. The rotating edge mop lifts together with the main mop, the DuoRoller Riser brush lifts in mop-only work, and Carpet Boost+ is rated by Roborock at a 99.5 percent hair pick-up rate in Max+ mode. Very dark or shag carpet can still be read as a drop by the cliff sensors.

VibraRise 3.0 uses two vibration modules that scrub up to 4,000 times per minute to lift dried-on stains, while a rotating Extra Edge mop spins at up to 185 rpm to clean within 1.68 mm of baseboards and the FlexiArm side brush extends into corners. By default the robot returns to the dock every 15 minutes of mopping for a wash, which you can change on the wash settings page, and you can start a wash by holding the dock button while the robot is docked. The dock re-washes the mop and sends the robot back to re-mop areas its dirt detection flags.

Reactive AI 2.0 combines 3D structured light with an RGB camera to recognize 73 object types, including shoes, pet waste, and even floor mirrors, and to steer around obstacles as small as 5 cm wide and 3 cm tall; it shows a real-time obstacle icon on the map and stores one photo per recognized object that you can review in the app. Pet recognition stops the main brush and moves the robot aside, the app can snap pet photos and search for a pet, and the camera supports video calls and remote cruising. The built-in Hello Rocky assistant processes commands on the robot, so start, pause, dock, and suction or water changes work even without a network.

The S8 MaxV Ultra connects to 2.4 GHz Wi-Fi only; 5 GHz is not supported, so on a dual-band router join the 2.4 GHz network by name. Amazon Alexa, Apple Siri, and Google Home are supported once the robot is linked in the Roborock app; for Alexa, enable the Roborock Plus skill, sign in with your Roborock account, and run Discover Devices. If pairing fails, check the password, allow location and local network permissions for the app, turn off any VPN or cellular data, select your home network rather than the robot's own hotspot, and avoid WEP security or special characters in the network name. Without Wi-Fi the robot still runs full cleanups from its buttons or by voice; schedules, maps, and the camera features need the app.

The mop is only washed if it was used and the robot started from the dock with the dock on the map; if washing fails, check that the clean water tank is seated and filled and the water filter is installed. Auto-emptying and auto-drying each have to be enabled in the app, emptying skips when the dust container cover is off, and weak emptying usually means the main brushes or brush cover are not seated or the filter, air duct, or bag is blocked. A steady red dock light points to a missing dust container cover, a water tank that needs refilling or reseating, a missing water filter, or a voltage error; if the floor stays dry, raise the scrub intensity and water flow in the app. The robot will not resume a paused job during Do Not Disturb (22:00 to 08:00 by default) or if you placed it on the dock by hand.

Clean the DuoRoller main brushes every 2 weeks and replace them 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; wash the VibraRise and edge mop cloths as needed and replace them every 3 to 6 months. Clean the dock's high-speed maintenance brush as needed and replace it every 6 to 12 months, rinse the cleaning tank and water filter as needed, and change the dust bag when it is full, about every 7 weeks. Use only cold water in the tank and only Roborock cleaning solution in the detergent cartridge, never disinfectant, and run the robot between 39 and 104 F (4 to 40 C).

Put the dock on a hard, level floor against a wall with at least 0.82 m (2.7 ft) of height, 0.42 m (1.4 ft) of width, and 1 m (3.3 ft) of depth kept clear, in a spot with a good Wi-Fi signal. Roborock lists obstacles near the dock as the usual reason the robot cannot return, so clear them or move the dock to an open area, and place the robot closer if it is far away. Wipe the signal window on the dock and the robot's front sensor, and set the robot on the dock by hand if it was carried to another room so it can relocate itself; a full charge takes about 4 hours.

The robot, the RockDock Ultra dock, one mop cloth, one mop cloth mount, one dust bag, the power cable, and the user manual. The robot measures 13.8 x 13.9 x 4.06 inches and the dock 16.1 x 16.5 x 18.5 inches.
