3i returned to CES this year with exciting updates to its robot vacuum lineup, including the debut of two new models: the P10 Ultra and the G10+. The company is also showcasing the S10 Ultra, which launched this past November and gained significant attention in 2024 for its innovative water-recycling feature.
S10 Ultra’s WaterRecycle™ System
Officially launched in November 2024 and on display at CES 2025, the S10 Ultra’s standout feature remains its WaterRecycle™ System. By combining water distillation from the mopping process with moisture extracted from ambient humidity, the vacuum aims to reduce or eliminate the need for traditional refilling.
See our previous coverage of the S10 Ultra , which outlined how 3i’s approach to eliminating manual refills set this device apart.
The 3i S10 Ultra Robot Vacuum and Mop introduces the world’s first WaterRecycle System, which recycles and distills wastewater into a continuous supply of purified water—no plumbing or drainage needed. Its UltraReach Extendable Roller Mop, spinning at 330 rpm with 12 spray holes, delivers a constant 7N mopping pressure and automatically extends for millimeter-precision edge cleaning. Powered by 13,000Pa suction, it tackles dirt, hair, and debris on carpets and hard floors. Advanced AI algorithms, dToF LiDAR, and Dual 3D Structured Light provide seamless navigation and obstacle avoidance, while the Dual Anti-Tangle main brush prevents hair clogs. The 12-in-1 dock enables automatic mop washing, drying, and self-emptying for up to 60 days of hands-free cleaning. Easily set up custom cleaning via the 3i App, or control it using Alexa and Google Assistant.See additional info

Apart from this recycling system, the S10 Ultra offers a 13,000 Pa vacuum, a continuous roller mop designed for edge-to-edge cleaning, and an all-in-one docking station. Its navigation relies on ApexVision™ dToF LIDAR for precise mapping, while a dual anti-tangle design helps manage hair pickup.
The 3i P10 Ultra
Unlike the S10 Ultra, which claims water recycling and distillation without the need to refill it, the new P10 Ultra robot vacuum (Amazon link) utilizes a more traditional docking station. However, it incorporates several features that reduce the need for hands-on upkeep. The station handles automatic mop cleaning and hot-air drying to prevent lingering moisture.
The P10 Ultra’s UltraReach™ Edge Mopping System uses a robotic arm with a spinning mophead to reach along walls and corners. For navigation, it combines LDS lidar and AI obstacle avoidance. It features DirtScan™, which uses AI recognition with automatic lighting and adjusts suction and mopping levels for difficult messes. In addition, it offers voice assistant integration, app-based customization, and TUV-certified privacy controls.
The 3i G10+
The G10+ arrives with a charging station, but not a docking station. Instead, it incorporates a debris compactor in its onboard dustbin, compressing dirt and debris for up to 60 days before it needs to be emptied. This design also uses UV light to discourage bacterial growth.
Like the P10 Ultra, the G10+ includes an extending mophead and side brush for coverage in corners and supports AI-driven adjustments for different types of messes. Compatibility with Alexa and Google Assistant adds to its convenience, while features like a child lock and privacy-focused AI round out the package.
The P10 Ultra and the G10+ both claim 18,000 Pa of suction.
Release & Availability
The S10 Ultra is on the market, having launched in November 2024.
The P10 Ultra and G10+ were introduced at the show, with 3i indicating that more details about final launch dates and pricing will be available soon.
Based on last year’s interest in 3i’s water recycling technology, these models appear to continue the company’s focus on reducing user intervention and addressing common pain points in robot vacuum maintenance.
