Robot vacuums reached the corner problem years ago: every flagship sucked hard, and none could reach the corner behind the sofa leg. Roborock’s answer is the Qrevo Master – a $1,399.99 flagship whose whole story is the dual FlexiArm: a mechanical side brush that kicks out to sweep edges and a mechanical mop arm that extends to wipe baseboards. This review aggregates official specs, retail pricing, and owner feedback; we do not claim hands-on testing.
The short version: the Qrevo Master pairs 10,000Pa suction (per official specs) with the dual-arm cleaning system, hot-water mop washing, a self-cleaning dock, and the three-lift system – mop, side brush, and main brush all rise for carpet-only mode. The honest catch: the arms are the headline but the 10,000Pa suction is mid-flagship (the X50 Ultra runs 19,500Pa), the dock is bulky, and at this price the app polish still lags Dreame’s.
What stands out
- Dual FlexiArm system: the side brush extends 4cm to sweep edges and the mop pad extends to wipe baseboards – the “no corner is safe” feature that made owners watch it work.
- 10,000Pa suction: strong enough for carpets and pet hair (official spec; owners say deep-pile needs two passes).
- Hot-water mop washing: the dock washes the mop in hot water, dries it with hot air, and self-cleans the washing tray – the “mop never smells” claim that holds in owner threads.
- Three-lift design: mop, side brush, and main brush all lift on carpet – the robot goes full vacuum-only mode, not drag-a-wet-mop-across-the-rug mode.
- Smart dock: auto-empty, auto-refill, and self-cleaning in one base – two months between dust-bag changes on average, per owner reports.
Across Chinese owner communities
Chinese owner communities – heavy on overseas users who track Roborock against Dreame and MOVA on every flagship release – run the Qrevo Master through one blunt filter: “买 Master 就是买那两条机械臂，其他都是赠品” (you buy the Master for the two mechanical arms – everything else is a bonus). The consistent praise: “墙角桌腿终于不用自己擦了，机械臂真伸进去了” (corners and table legs finally need no hand-wiping – the arm really reaches in), “热水洗拖布确实不臭了” (hot-water mop washing really kills the smell), and “地毯识别抬抹布很准，不会湿地毯” (carpet detection lifts the mop accurately – no wet rugs). The common complaints: “吸力 10000Pa 在旗舰里算小的，大颗粒偶尔吸不干净” (10,000Pa is low for a flagship – large debris sometimes survives), “基站太大了，小户型没地方放” (the dock is huge – no room in small apartments), and “App 不如追觅花哨，自动化要自己折腾” (the app is less polished than Dreame’s – automations need DIY). Owner pricing wisdom: “标价 1399 是虚的，999-1099 才是社区心理位” (the $1,399 list is fake – $999-1,099 is the community line).
The honest catch
Four honest limits on the Qrevo Master. First, suction is the weak flank: at 10,000Pa the Master is out-sucked by the Dreame X50 Ultra (19,500Pa) and even mid-tier rivals, and owners report large debris or deep-pile carpets need a second pass – the arms are the reason to buy it, not the vacuum. Second, the dual-arm magic has a size cost: the dock is one of the biggest in the class, and small-apartment owners’ first complaint is always the footprint, not the cleaning. Third, the app is functional but dated: Roborock’s app maps, schedules, and automates fine, but it lacks the polish and scene presets of Dreame’s – owners call it “够用，不炫” (sufficient, not flashy). Fourth, $1,399.99 is a fantasy price: the honest street price is $999.99-1,199.99, and owner threads say the $999 floor arrives at Black Friday – anyone paying list overpaid by $200-400. Match it to the job: it is the right flagship for baseboards, corners, and edge-obsessed homes, and the wrong one for suction-first buyers.
Typical street price
The Roborock Qrevo Master lists at $1,399.99 and holds a street price of $999.99-1,199.99, with event floors tracking toward $999.99. Chinese owners’ buy line is $999.99 – the price where the dual-arm system stops being a luxury and becomes the obvious flagship pick.
Bottom line
The Roborock Qrevo Master is the dual-arm flagship at $1,399.99 (realistically $999.99-1,199.99 on sale): 10,000Pa suction, extending side brush and mop, hot-water mop washing, three-lift carpet mode, and a self-cleaning dock. The honest trade-offs are mid-flagship suction, a bulky dock, and a dated app. Chinese owners’ one-liner is the whole review: “买 Master 就是买那两条机械臂” – and their rule is to buy at the $999.99 Black Friday floor, because the corner-cleaner is only worth its price when the list price stops being real.
