Roborock S8 MaxV Ultra Review: Worth the Premium?

The Roborock S8 MaxV Ultra represents the current ceiling of robot vacuum technology. At approximately $1,800, it costs more than many people's regular vacuum, mop, and cleaning supplies combined for five years. But it also does things that no other robot does as well. We tested it for six weeks in a 2,400-square-foot home with two dogs to see if the premium is justified.

What Makes It "Ultra"

The S8 MaxV Ultra is a robot vacuum and mop with an all-in-one dock that washes the mop pads, refills the water tank, empties the dustbin, and dries the mop pads with hot air. The robot itself features dual rubber brush rolls, a VibraRise mopping system that lifts the mop pad onto the robot's top surface when it detects carpet, and a reactive 3D obstacle avoidance system powered by a front-facing camera and structured light sensor.

In plain English: you set it up, create a cleaning schedule, and forget about it for weeks at a time. The dock handles all the maintenance that made earlier robot mops inconvenient.

Navigation and Mapping

The S8 MaxV Ultra uses LiDAR plus a front-facing camera with AI object recognition. During its initial mapping run, it built a precise floor plan of our test home in 22 minutes. Room detection was accurate — it correctly identified the kitchen, living room, hallway, bedrooms, and bathrooms without manual correction.

The 3D obstacle avoidance is the best we have tested. It identified shoes, dog bowls, charging cables, and a dog toy scattered across the floor. It navigated around each obstacle with about one inch of clearance, which is close enough to clean nearby while avoiding the object. In six weeks, it got stuck zero times.

Vacuuming Performance

Suction power reaches 6,000 Pa, which is the highest in any robot vacuum we have tested. On hard floors, it picked up flour, cereal crumbs, and dog hair with a single pass. On medium-pile carpet, it extracted embedded dirt that our previous robot (a Roomba j7+) left behind.

The dual rubber brush rolls spin in opposite directions to prevent hair tangles. After six weeks with two shedding dogs, we never had to manually remove wrapped hair from the brushes. This alone is a major quality-of-life improvement over single-brush robots.

Edge cleaning is above average for a circular robot but still not perfect. It gets within about half an inch of baseboards, which leaves a thin line of dust in corners. We addressed this with monthly manual touch-ups.

Mopping Performance

This is where the S8 MaxV Ultra separates itself from cheaper competitors. The VibraRise system vibrates the mop pad 4,000 times per minute while applying consistent downward pressure. It scrubbed dried coffee and tomato sauce off tile flooring that a passive drag-mop from a budget robot would have left behind.

When the robot encounters carpet, it lifts the mop pad completely off the floor and onto the top of the robot body. Carpet stays dry. This sounds like a small detail, but it means you can schedule the robot to vacuum and mop your entire mixed-floor home in one session without worrying about wet carpet.

The dock washes the mop pads with clean water after each session and dries them with hot air to prevent mildew. In six weeks, the pads never smelled musty.

The Dock

The dock is large — roughly the size of a small end table. It holds enough clean water for about four mopping sessions and enough dustbin capacity for about six weeks of vacuuming in our 2,400-square-foot home.

Refilling the clean water tank and emptying the dirty water tank takes about two minutes every two weeks. Emptying the dustbin bag takes 30 seconds once a month. This is genuinely close to a set-and-forget cleaning solution.

What We Did Not Love

The price is the obvious criticism. At $1,800, this is a premium appliance. The Roborock Q7 Max+ offers 80% of the cleaning performance for about $500 with its self-empty dock. You are paying a steep premium for the mopping dock, 3D obstacle avoidance, and maximum suction power.

The app, while functional, has too many settings. There are adjustable suction levels, mop pressure levels, water flow rates, room-specific cleaning orders, and dozens of other options. Most users should stick with the defaults and resist the urge to optimize.

The Verdict

The Roborock S8 MaxV Ultra is the best robot vacuum and mop available today. It vacuums powerfully, mops effectively, avoids obstacles reliably, and its dock handles maintenance automatically. The question is not whether it is good — it is whether you value your cleaning time at $1,800.

For large homes with pets, mixed flooring, and busy schedules, the answer is yes. For small apartments or homes with only hard floors, a $400-600 robot delivers excellent value without the ultra-premium price.
