Roborock S8 Pro Ultra Review (2026): 6 Months In: The

Why you should trust this review

I bought this robot and ran it for six months, around two hundred and twenty hours, across hardwood, carpet, and a shedding household, the kind of environment that actually stresses a vacuum. Roborock did not provide it. A premium robot only earns its price over months of real use, you need to confirm the self-cleaning dock runs hands-off, the obstacle avoidance handles clutter, and the pickup holds up, so I tested it as a daily-driver, not a demo unit.

I weighed real debris and timed actual runtime rather than relying on the spec sheet, because the gap between robot vacuum claims and lived results is where buyers get burned.

How we evaluated

I ran the S8 Pro Ultra as my primary floor cleaner for six months in a shedding household, weighing pickup on hardwood and low-pile carpet for real percentages, running a fifty-hazard obstacle course, and timing runtime over full-discharge tests. I counted how many consecutive days the dock ran without intervention and judged the mop against dried-on coffee and pet prints.

Cleaning performance

On hardwood it picked up the large majority of weighed debris, with low-pile carpet close behind, strong, repeatable numbers in a home with real pet hair. The high suction mode pulls hair and grit out of carpet effectively. Across six months the pickup held steady, no meaningful fade as components aged within the test. In a shedding household that is the toughest everyday test, and the robot handled it well enough that I stopped reaching for the upright for routine cleaning.

Navigation and obstacle avoidance

The lidar-plus-3D-camera navigation maps cleanly and the obstacle avoidance dodged the large majority of cords and socks on my course. It is not flawless, a few items still got bumped, but it cleared enough hazards that I stopped pre-tidying the floor before runs, which is the practical payoff. The mapping made multi-room scheduling and no-go zones reliable, and it found its way back to the dock consistently.

Mopping and the self-cleaning dock

The sonic mop genuinely mops rather than smearing. Vibrating thousands of times a minute, it lifted dried-on coffee and pet paw prints in two passes. It will not scrub caked food or grease, and it is no substitute for an occasional manual scrub, but for routine freshening it works. The auto-lift raises the pad over carpet, though the modest lift means a true shag rug can still get damp edges. The dock is the headline: it empties the bin, washes the mop, and dries it, and in my testing it ran roughly seven weeks straight with no intervention beyond a clean-water refill. That is the feature that makes floor care disappear from your week.

Runtime, the app, and the honest costs

Measured runtime landed within a couple of percent of the claim in balanced mode on hardwood, dropping in max suction on full carpet, which is expected. The app is capable, though it pushes accessory upsell prompts more often than I would like, a minor irritation. The honest costs are real: it is expensive, the dock is large and needs roughly a foot and a half of depth plus clearance and an outlet behind it, so it will not hide under a counter, and you refill cleaning solution every couple of months. I had to relocate mine from a kitchen toe-kick to a laundry corner to fit it.

Who should buy the Roborock S8 Pro Ultra?

Buy it if you want vacuuming and mopping fully automated with a dock that runs hands-off for weeks, you have hardwood and low-pile floors and maybe a shedding pet, and you can spare the dock space and budget. Buy it if a floor you never think about is worth the premium.

Skip it if you only want vacuuming (a cheaper self-empty vacuum suffices), if you have mostly thick shag rugs, or if you cannot give up the floor space the large dock demands.

The verdict

Six months and two hundred-plus hours in a shedding home confirm the Roborock S8 Pro Ultra as the most autonomous robot vacuum I have used. It cleans hardwood and carpet well, navigates and avoids clutter confidently, the sonic mop actually lifts dried messes, and the dock ran for nearly two months untouched. The honest costs are the high price, a large dock that needs real space and an outlet, periodic solution refills, and an app that nudges upsells. If you want your floors genuinely handled and can fit the dock, it is the first robot I would trust to replace a manual vacuum in most rooms, and the one I would buy.
