The roborock S8 MaxV Ultra offers near hands-free cleaning for plumbed-in homes, best for homes with plumbing near the dock. Rated 3.7 out of 5 across 55 user ratings. The main drawback: needs a water supply and drain near the dock. We scored it 3.7 out of 5.
This version of the S8 MaxV Ultra removes the last chore a robot mop leaves you, filling and emptying water tanks, but only if you can plumb its dock into a water supply and a drain. Get the installation right and the robot vacuums at 10000Pa, mops with a lifting VibraRise 3.0 pad, washes and hot-air dries its own mop, and empties its own bin; get it wrong and you have bought the wrong model.
NoFussDeal rates the roborock S8 MaxV Ultra 3.7 out of 5 at $849.99. Last updated September 26, 2026.
roborock rates the S8 MaxV Ultra at 10000Pa HyperForce suction and pairs it with a dual-roller rubber brush. Rubber rollers shed wound hair better than bristles, which is why the design aims at fewer tangles rather than just more pull.
The FlexiArm side brush extends automatically when the robot detects a corner or a low gap under furniture. A separate rotating side mop swings out to wet the floor closer to the wall, with roborock quoting an edge margin under 1.68mm.
This version of the dock fills the robot's water tank automatically and drains the dirty water, alongside the usual RockDock Ultra jobs: hot-water mop washing, automatic detergent dosing from a 580ml tank, hot-air drying of mop and base, and dust emptying during and after cleaning.
3D structured light measures the shape of objects in the robot's path while an RGB camera identifies them, so it can steer around shoes, cables, pet waste and even floor mirrors. The same camera powers video calling and remote cruise through the app.

Before unboxing, confirm the dock can sit within reach of both a water supply and a drain, with room around it for the robot to dock. This version depends on those connections to refill and drain itself.
Connect the dock's water inlet and drain following roborock's installation guide, then run a refill so you can check the joints for leaks before the robot starts relying on them.
Seat the robot on the dock to charge, install the roborock app on your phone or tablet, and add the robot. You can also control it with the built-in "Hello Rocky" voice assistant, which works without a network connection.
Pick up cables, clothes and small clutter and open interior doors before the first run so the robot builds a complete map. Label rooms in the app afterwards.
Fill the 580ml detergent tank in the dock. It doses automatically, so you do not need to measure detergent each time.
Choose suction and mopping settings per room, mark rugs and no-go areas, and schedule runs for when the floor is clear and dry.
Only for some buyers: we score it 3.7 out of 5. The S8 MaxV Ultra with Refill & Drainage does the most a robot vacuum and mop can do without you: it vacuums at 10000Pa, mops with a lifting pad, reaches corners with the FlexiArm brush, and washes, dries, refills and drains itself at the dock. Rated 3.7 out of 5 across 55 user ratings.
Needs a water supply and drain near the dock. Saved map can drift over time with no way to lock it.
Dirt detection checks how dirty the mop is while it is being washed and washes it again if needed, and sends the robot back over heavily soiled patches.

The S8 MaxV Ultra with Refill & Drainage does the most a robot vacuum and mop can do without you: it vacuums at 10000Pa, mops with a lifting pad, reaches corners with the FlexiArm brush, and washes, dries, refills and drains itself at the dock. What decides whether it is worth it is less the cleaning than the fit. You need plumbing where the dock will live, a floor that is tidy and dry before runs, and patience with a map that can drift.
Buy this version only if you can plumb the dock in; if you can't, the freestanding S8 MaxV Ultra dock is the one to look at. Where it fits, it takes almost all the routine work out of floor cleaning. Keep floors clear, send the robot home before restarting a stuck job, and expect to redo the map occasionally.
