The Roborock P20 Live Water Edition is coming, and it’s rolling in with a major shift in mop tech. Unlike previous models that relied on vibrating or rotating pads, this new vacuum-mop hybrid introduces a roller mop system, marking a first for the brand.
Roborock P20 Live Water Edition debuts roller mop cleaning

Unveiled on Weibo, Roborock’s teaser showcases the upcoming P20 Live Water Edition as a mop-first machine. The roller mop design, as seen in the promo video, suggests constant contact with the floor surface and potentially better edge-to-edge cleaning compared to standard pad setups.
More interestingly, the “Live Water” branding hints at a continuous stream of clean water being delivered to the mop roller. That setup would help reduce smearing dirt around, a common issue with static mop pads. A built-in scraping mechanism also appears to help strip dirt from the mop as it rotates, keeping it fresher between dock visits.
Specs remain secret, but clues point to serious hardware
While Roborock hasn’t dropped the full spec sheet yet, it’s likely the P20 Live Water Edition will mirror some capabilities of the recently launched P20 Ultra Plus (aka Qrevo Curv 2 Pro globally). If that’s the case, here’s what might be under the hood:
- Up to 25,000 Pa suction power
- AdaptiLift Chassis to raise the mop over carpets
- Retractable LDS module for precise navigation
- Self-cleaning dock with drying and water refills
- Smart obstacle climbing and mapping features
What sets the Roborock P20 Live Water Edition apart:
- Roborock’s first roller mop system
- Likely live water feed for continuous mopping
- Built-in dirt scraping tool for the roller
- Potential integration with existing top-end features
- Launching initially in China
A clean slate for robot mopping
With the P20 Live Water Edition, Roborock isn’t just iterating, it’s rethinking how mopping works in robot vacuums. The switch to a roller system could be a game-changer for users frustrated with smeared floors or ineffective cleaning cycles.
Full details and a global release date remain under wraps, but this teaser makes one thing clear: Roborock’s next vacuum isn’t just spinning in circles. It’s rolling forward.
