Anker is selling a €1,499 robot vacuum that does more than vacuum and mop: the Eufy HydroJet S2 can also dispense room fragrance on request. That matters most for buyers already shopping at the top end of smart-home cleaning, where basic suction, app maps, and self-emptying docks no longer separate flagships from the pack.
The Eufy HydroJet S2, launched at Anker Day in New York, is now officially on sale after a pre-order phase, according to Notebookcheck. It follows the Eufy S1 Pro, which had already pushed Anker’s smart-home brand deeper into premium floor care. The new model adds a wider roller mop, stronger suction, AI navigation without a laser turret, and a scent diffuser with three fragrance options.
MLXIO analysis: the fragrance function is easy to dismiss as a gimmick. It may be one. But its real signal is sharper: robot vacuums are being pushed from cleaning devices into broader home-care appliances, where hygiene, smell, floor finish, and reduced maintenance all become part of the purchase case.
Builders: Anker Is Moving Beyond Suction Specs and Into Sensory Features
For Anker and Eufy, the HydroJet S2 is not just another suction-number upgrade. The device is built around HydroJet 2.0, a 29 cm roller mop, and an integrated scent diffuser that can release Citrus & Basil, Bamboo & Sage, or Bergamot & Lychee.
The question for product teams is simple: if most premium robot vacuums already promise mapping, obstacle avoidance, and self-cleaning docks, where does differentiation come from next?
Anker’s answer appears to be floor contact and room ambience. The S2’s roller mop can extend up to 15 mm to the side, apply 15N of pressure, and rinse itself with fresh water from 32 water jets, per Notebookcheck. That combination targets one of the category’s harder problems: cleaning along edges and handling sticky dirt, not just collecting loose debris.
A press release distributed by EIN Presswire describes the U.S. version as the Robot Vacuum Omni S2, with pre-sale beginning January 6, a launch date of January 20, and an MSRP of $1599.99.
The release calls the S2 the robot vacuum with the “world’s first built-in aromatherapy system for a robot vacuum.”
That is a marketing claim, not independent test data. But it shows how Eufy wants the product framed: not only as a cleaner, but as a device that changes how a room feels after cleaning.
Buyers: The Roller Mop Solves a Real Problem; Fragrance Is More Personal
For end users, the HydroJet S2 splits into two stories. The roller mop addresses visible cleaning performance. The fragrance system addresses perception.
The mop hardware is the more concrete upgrade. A wide rolling surface creates continuous contact with the floor, while the side extension is designed to reach edges that round robot bodies often miss. The source material does not prove the S2 cleans better than rivals in real homes, and Notebookcheck explicitly says actual floor performance matters more than the headline suction rating. That caveat is important.
The fragrance system is different. It may appeal to households that want a room to smell freshly cleaned after the robot runs. Pet owners may also see value in odor masking. But fragrance-sensitive users may see the same feature as a drawback, especially in homes with allergies, asthma, children, or scent sensitivity.
So who benefits most? Buyers who already wanted a high-end mop-first robot and view scent as a bonus rather than the reason to spend flagship money.

MLXIO analysis: if the S2’s fragrance feature becomes popular, buyers should pay attention to cartridge availability and replacement cost, not just the initial robot price.
Retailers and Consumables: The Scent Cartridge Could Matter After the Sale
The HydroJet S2 is expensive enough that Anker needs more than a spec sheet to justify the price. The base station is part of that argument. Notebookcheck describes it as a sleek, fully equipped dock that charges and cleans the robot. The press release says the UniClean Station 2.0 automatically empties the dustbin, washes and dries the mop, refills water, and manages detergent.
Could fragrance cartridges become a small but sticky repeat-purchase line?
The supplied press release says each scent cartridge lasts about 45 days, and replacement cartridges are available to purchase. That puts fragrance beside more familiar robot-vacuum consumables such as dust bags, filters, cleaning solution, brushes, and mop parts.
This is where launch economics matter. For broader MLXIO coverage of consumer-tech pricing tactics — not as direct Eufy comparisons — see our reports on Forza Horizon 6’s 33% launch discount and Mova’s €300 discount and free smart meter offer. The Eufy story supplied here is different: a flagship floor-care device launching around a four-figure price, with possible ongoing purchases attached.
For retailers, that can be attractive if users like the feature. For buyers, it adds another line item to consider before checkout.
Competitors: Mopping Is Becoming the Harder Battlefield Than Vacuuming
Notebookcheck notes that the S2’s 30,000 Pa suction is “not an extraordinary figure compared to top models from other manufacturers.” That line says a lot. Suction ratings are still useful, but they are no longer enough to carry a flagship pitch by themselves.
The harder test is wet cleaning. Can the robot remove stubborn dirt? Can it reach edges? Can it avoid dragging dirty water across the floor? Can the dock clean the mop well enough that the user does not have to babysit it?
The S2’s answer is a system: roller mop, pressure, fresh-water rinsing, side extension, and dock maintenance. CleanMind AI with 3D MatrixEye 2.0 handles mapping, navigation, and obstacle avoidance without a laser turret. The press release adds claims about identifying more than 200 common household obstacles and recognizing stains such as ketchup and pet footprints, then adjusting water levels, mop pressure, and scrubbing duration.
The open question: will real-world reviews show that these AI and mopping claims translate into cleaner floors, or just longer feature lists?
Until independent tests are broad enough, the safest reading is that Anker is competing where vacuuming is hardest to fake: sticky messes, edges, hair, rugs, odor, and maintenance.
The Market Signal: Future Robot Cleaners May Sell Hygiene and Ambience, Not Just Automation
The HydroJet S2 points toward a premium robot-vacuum category where the pitch is no longer “it cleans while you are away.” That promise is now table stakes at the high end. The new pitch is closer to: it cleans, washes itself, manages water, avoids clutter, treats stains, handles odors, and leaves the room feeling finished.
That is more ambitious. It also creates more reasons for buyers to be skeptical.
Before paying flagship money, shoppers should check:
- Floor fit: hard-floor area, rugs, thresholds, and edge-heavy rooms.
- Maintenance: dock cleaning, detergent, dust bags, mop roller wear, and water handling.
- Fragrance control: whether scent can be disabled, adjusted, or skipped.
- Consumables: scent cartridge pricing and availability.
- Review evidence: actual stain removal and edge cleaning, not just suction ratings.
MLXIO analysis: the S2’s success will depend less on whether fragrance sounds novel and more on whether users feel the whole system reduces chores without adding new ones. Evidence that would support Anker’s bet includes strong independent cleaning tests, low maintenance complaints, and repeat purchases of scent cartridges. Evidence that would weaken it would be simpler: buyers praising the mop but ignoring the fragrance, or treating it as an expensive extra attached to an already costly robot.
Key Takeaways
- Anker is pushing robot vacuums beyond cleaning into broader home-care features like fragrance and floor finish.
- The €1,499 price puts the Eufy HydroJet S2 firmly in the premium smart-home cleaning category.
- Features like a roller mop, AI navigation, self-rinsing jets, and scent options show how flagship robot vacuums are competing on convenience and ambience.
