Eufy Launches Robot Vacuum Omni S2, Anker's Flagship Cleaner with 3.8x Stronger Suction at 249,900 Yen
Anker Japan released the Eufy Robot Vacuum Omni S2, a fully automatic robotic vacuum cleaner under its Eufy smart home brand, on May 27, 2026[1]. Positioned as the highest-end model in Anker's robot vacuum lineup, the new flagship packs every premium feature into a single chassis, including up to 30,000 Pa of suction power and a roller mop that self-cleans using ozonated water generated at its base station. The retail price is 249,900 yen including tax[1].
3.8x More Suction Than the Previous Model
At the heart of the Omni S2 is the newly developed AeroTurbo 2.0 system[1]. A powerful cyclone structure efficiently separates dust and debris, suppressing clogs inside the dustbin while maintaining strong airflow over long cleaning sessions.
The peak suction power reaches 30,000 Pa, roughly 3.8 times the figure of its predecessor, the Eufy Robot Vacuum Omni S1 Pro[1]. Pa stands for pascal, a common metric for robot vacuum suction strength. The 30,000 Pa figure positions the Omni S2 at the top tier of consumer robot vacuums, designed to extract even fine dust embedded deep inside long-pile rugs.
The body uses a square shape that lets the unit reach corners and along skirting boards more efficiently than the typical round design[1]. Anker Japan says the goal was to reduce the kind of edge misses that plague conventional circular units, while balancing a minimalist design that blends naturally into a living space with the intuitive operation of a top-mounted touch panel[1].
HydroJet 2.0 Self-Cleans the Mop with Ozonated Water
The wet mopping setup has also been substantially upgraded. The Omni S2 carries a roller mop that applies up to roughly 1.5 kg of pressure, an industry-leading figure, while automatically extending outward to reach walls[1]. The rotating roller approach is intended to lift and wipe away dirt rather than smear it around with a static pad.
The standout is the HydroJet 2.0 system, which uses ozonated water generated at the base station to continuously self-clean the mop while the unit is in motion[1]. Ozone is known for its sanitizing and deodorizing properties, and the design directly tackles the long-standing problem of robot vacuums spreading dirty water across the floor. Anker Japan notes that the claim is based on third-party testing conducted in 2025, and adds the caveat that not all bacteria can be eliminated and that real-world results depend on the cleaning environment[1].
When the unit detects a rug or carpet, the mop section automatically lifts[1]. Long-pile carpets up to 5 cm thick can be cleaned without getting wet, a design choice that suits typical Japanese living rooms where wood flooring and rugs are often mixed in the same space[1].
3D Vision and AI Plan an Optimal Route for Each Room
Navigation is handled by the CleanMind AI system and the 3D MatrixEye 2.0 spatial recognition technology[1]. The former is an AI feature that recognizes and avoids obstacles with a precision close to that of the human eye, while the latter is a 3D visual sensor that captures the room in three dimensions. Together, they learn the layout of the room and the placement of furniture, and automatically design an optimal cleaning route for each space[1].
The Omni S2 is also strong on step traversal, clearing continuous steps up to 4.2 cm in height[1]. Specifically, it handles a two-stage step of up to 4.2 cm or a single step of up to 3.5 cm, allowing it to cross common Japanese household obstacles such as sliding door rails and raised thresholds and continue cleaning into adjacent rooms on its own[1].
Fully Automatic Self-Cleaning Cuts Maintenance to a Minimum
The base station carries a fully automatic self-cleaning function that significantly reduces day-to-day maintenance[1]. Dust collection from the bin, hot water mop washing, hot air mop drying, and automatic detergent dosing are all handled in one continuous workflow. A built-in dirt sensor inside the station detects how soiled the mop is and automatically optimizes the wash cycle[1].
On the cleaning head side, the Omni S2 adopts the DuoSpiral brush, which splits the rotating brush into left and right halves and automatically pulls hair toward the center for vacuuming[1]. The structure is designed to address the chronic problem of long hair and pet shedding wrapping around the brush, reducing the need to manually remove and clean the brush. Anker positions the package as a unit that transforms daily cleaning from a chore into something that can simply be delegated[1].
Pricing and Sales Channels
The retail price is 249,900 yen including tax[1]. Sales channels include the dedicated page on the Anker Japan official online store[2], Anker Store retail locations, Amazon.co.jp, Rakuten Ichiba, and select home appliance retailers[1]. Within the Eufy lineup of fully automatic robot vacuums, the Omni S2 sits above the previous mainstay Omni S1 Pro as the new flagship.
Summary
The Eufy Robot Vacuum Omni S2 brings together 30,000 Pa of suction, an ozonated-water self-cleaning roller mop, 3D vision-based AI navigation, and a base station that handles cleaning maintenance end to end, packing every major robot vacuum feature into a single high-end unit. At 249,900 yen it is not a cheap proposition, but for households that want to automate daily cleaning as completely as possible, it stands out as the strongest pick in the current Eufy lineup.
