With Prime Big Deal Days closed and Black Friday seven weeks out, the most interesting robot vacuum on the market right now is not a 2026 flagship – it is the last generation’s flagship. The Roborock S8 MaxV Ultra launched at $1,799 in 2024, and its street price has been sliding ever since: it now sits around $999, with event lows near $749-799. The question Chinese owner communities are asking is the same one on every deal forum: is the old flagship a Black Friday steal, or a trap when the current flagships are barely more expensive? This article aggregates specs, pricing, and owner feedback; we do not claim hands-on testing.
The short version: the S8 MaxV Ultra is still a genuinely excellent vacuum, and at $749-799 it undercuts the current flagships by $150-300 while delivering most of the real-world performance – but it lacks the current-gen fixes (anti-tangle roller, better edge cleaning) that owners actually notice, so the “steal” verdict depends on what you clean with.
Across Chinese owner communities
On Xiaohongshu and 什么值得买, the S8 MaxV Ultra occupies a strange spot: nobody is buying it at full price anymore, but it gets a steady stream of “还是上一代划算” (the last gen is still the better deal) posts whenever the price dips. Owners consistently praise three things: the 10,000Pa suction is still top-tier in real use, the VibraRise 3.0 sonic mop scrubs better than many current-gen spinning pads, and the RockDock’s hot-air drying is not marketing – it genuinely keeps the mop dry. The recurring complaints are the opposite of the praise: hair wraps around the fixed rubber roller (the anti-tangle roller arrived with the next gen), edge cleaning still misses corners, and the app is being slowly deprioritized as Roborock moves attention to newer models. The community verdict: “会买，但只会在 $799 以下买” – worth it, but only below $799.
What stands out
- 10,000Pa suction: still a top-tier number in 2026, and owners confirm it performs like it – deep-carpet pickup is genuinely strong.
- VibraRise 3.0 sonic mopping: the vibrating mop scrubs 3,000 times a minute and lifts when it hits carpet – many owners rate it above current spinning-pad mops.
- 8-in-1 RockDock Ultra: self-emptying, self-washing, self-drying, self-refilling, plus detergent dosing – the full station experience that is still rare below $1,000.
- Dual rollers and Reactive 3D obstacle avoidance: solid pickup on hard floors and competent navigation – the 2024 flagship kit is not outdated in the ways that matter most.
The honest catch
There are three reasons the “steal” verdict is not automatic. First, the hair problem: the S8 MaxV Ultra uses a fixed dual-roller brush with no anti-tangle design – in Chinese owner communities, “缠头发” (hair wrap) is the single most repeated complaint, and the current-gen Curv/Master exist specifically because of it. If you have long hair or pets, the price gap with the current gen narrows fast. Second, edge cleaning: corners are still missed – the FlexiArm edge-mop and extended-side-brush fixes belong to the newer generation, so the old flagship cleans the middle of the room beautifully and the edges averagely. Third, ecosystem drift: Roborock’s app and firmware attention has moved on; you are buying a maintained product, not a priority product. None of this changes what it does well – at $749-799 it is a lot of flagship for the money, and at $999+ the current-gen premium is the better buy.
Typical street price
Launch price was $1,799. Street price now sits at $999-1,099, with recurring event lows at $799 and the best observed lows near $749 during deep sales. After Prime Big Deal Days the price has drifted back above $1,000 – the pattern points to Black Friday week bringing it back to the $749-799 band, which is the price where the community’s “值得买” verdict actually activates.
Bottom line
The Roborock S8 MaxV Ultra is the best argument for buying last-gen at the right price: a 2024 flagship whose real-world strengths (suction, sonic mop, full station) are unchanged, at $150-300 under the current generation. Buy it below $799 if your home is hard-floors-first or you are hair-tolerant and value the mop; pay the premium for the Curv/Master anti-tangle roller if hair is your daily battle. After PBD, the move is the same as for every flagship: set $749-799 as your floor and let Black Friday week do the work.
