In this Roborock Qrevo Curv 2 Flow vs P30 Pro vs G30S Ultra comparison, we look at three important roller mop robot vacuums from Roborock. The Qrevo Curv 2 Flow has already reached global markets, while the P30 Pro and G30S Ultra made their debut in mainland China in August 2026.
At the moment, there is no confirmed overseas version of the P30 Pro officially available in the global market. The G30S Ultra is also a mainland China model, not an overseas version of the P30 Pro. But comparing these three models still tells us a lot about where Roborock’s cleaning technology is going next.

For techTongBo, this trend is also important. We make replacement parts and accessories for robot vacuums and vacuum cleaners, so we pay close attention to the parts that users replace most often: roller mops, brushes, filters, dust bags, and dock-related parts.

Qrevo Curv 2 Flow: The Global Roller Mop Model
The Roborock Qrevo Curv 2 Flow is important because it brings Roborock’s roller mop system to overseas users.
It has a 270mm roller mop, 20,000Pa suction, 220 rpm roller speed, and 15N downward pressure. The roller mop uses 8 hydration points to keep adding clean water while it cleans. A scraper removes dirty water from the roller and sends it into a separate dirty water tank.
This is different from traditional dual spinning mop pads. A spinning mop pad can get dirty and keep wiping the floor. A roller mop is closer to a small floor washer. It keeps refreshing the roller while cleaning.
The Qrevo Curv 2 Flow also has a carpet-friendly design. Roborock says the roller mop can lift up to 15mm, and the machine has a Roller Shield to help keep carpets dry.
Its dock can wash the roller mop with water up to 75°C, dry it with 55°C warm air, and empty dust automatically. Roborock lists up to 65 days without manual dust emptying.

P30 Pro and G30S Ultra: A Stronger Hardware Direction in Mainland China
The Roborock P30 Pro is a newer mainland China model. It shows a more powerful hardware direction for roller mop robot vacuums.
The biggest difference is suction power. The P30 Pro has 40,000Pa suction, while the Qrevo Curv 2 Flow has 20,000Pa. More suction can help with pet hair, carpet dust, floor gaps, crumbs, and heavier debris.
The mop system is also stronger on paper. The P30 Pro uses a 270mm roller mop, the same width as the Qrevo Curv 2 Flow. But it spins faster at 240 rpm. It also has 15N downward pressure and a 16-hole spray system.
The biggest upgrade is heat. The P30 Pro supports 60°C hot-water mopping. Its dock can wash the mop with 100°C hot water and dry it with 63°C hot air.
This matters because cleaning performance is not only about the floor. It is also about keeping the mop itself clean. A damp mop can smell if it stays wet for too long. Hot-water washing and hot-air drying help reduce that problem.
The P30 Pro also has a low body. Its height is 8.98cm, which helps it clean under beds, sofas, and cabinets. It also supports 8.8cm dual-step obstacle crossing, which can help with thresholds, sliding door tracks, and thicker mats.
Roborock also released the G30S Ultra in mainland China on the same day as the P30 Pro. It is positioned higher in the same China-market roller mop lineup.
The G30S Ultra has 41,000Pa suction and supports 75°C hot-water mopping. Like the P30 Pro, it has an 8.98cm body, 100°C dock mop washing, 63°C drying, and 8.8cm dual-step obstacle crossing.
What These Models Tell Us About Roborock’s Future
The Qrevo Curv 2 Flow, P30 Pro, and G30S Ultra show a clear trend: Roborock is not just improving suction. It is changing how robot vacuums mop.
✔️ First, roller mops are becoming more important. Both models use a 270mm roller mop. This suggests Roborock sees roller mop cleaning as a serious long-term direction.
✔️ Second, robot vacuums are becoming more like automatic floor washers. Clean water supply, dirty water removal, scrapers, and roller pressure now matter more than before.
✔️ Third, the dock is becoming a key part of the product. The dock is no longer just a charging station. It now washes the mop, dries the mop, empties dust, and reduces daily maintenance.
✔️ Fourth, heat is becoming a premium feature. Qrevo Curv 2 Flow has up to 75°C dock washing. P30 Pro goes further with 60°C hot-water mopping and 100°C dock washing. G30S Ultra pushes the China-market lineup higher with 75°C hot-water mopping, 100°C dock washing, and 63°C drying.
✔️ Fifth, slim design still matters. Strong cleaning hardware is useful, but users also want the robot to reach low furniture. The P30 Pro’s 8.98cm body shows that Roborock is trying to balance power, mopping, and access.

What This Means for Robot Vacuum Accessories
Roller mop robots have more parts that touch water, dust, hair, and floor stains. Over time, users may need to replace or maintain:
roller mops
main brushes
side brushes
filters
dust bags
scraper parts
dock cleaning parts
water-related parts
A powerful robot can still lose cleaning performance if the roller mop is worn, the filter is blocked, or the dust bag is full. As roller mop models become more common, accessory quality will become more important.
Final Takeaway
The Roborock Qrevo Curv 2 Flow shows how Roborock is bringing roller mop cleaning to global users. It has 20,000Pa suction, a 270mm roller mop, 75°C dock washing, warm-air drying, and automatic dust emptying.
The Roborock P30 Pro and G30S Ultra show what the next China-market hardware step may look like. It has 40,000Pa suction, 60°C hot-water mopping, 100°C dock mop washing, 63°C drying, a low 8.98cm body, and strong obstacle-crossing ability. The G30S Ultra goes one step higher with 41,000Pa suction and 75°C hot-water mopping.
At the moment, there is no confirmed overseas version of the P30 Pro or G30S Ultra officially available in the global market. But if Roborock brings similar high-end roller mop models overseas later, they will be worth watching closely.
For users, the trend is simple: robot vacuums are moving from “sweep and wipe” to “wash and self-clean.” For techTongBo, that means one thing: smarter robots need better replacement parts.
