odor-free robot – Eufy’s Omni S2 combines a 30,000Pa vacuum, a fragrance diffuser, and hydrolyzed water cleaning to tackle pet hair without the lingering “vacuum breath” smell. The trade-offs are a tall dock, mid-to-low battery life at about 150 minutes, and the need to empty a
When you live with pets. robot vacuums stop being a convenience and start becoming part of the home’s air—good or bad. Maria Diaz described a familiar problem: even with frequent cleaning. vacuum and upright vacuums can keep a smelly residue inside their inner components. then release it when the vacuum runs or empties automatically at the dock.
Eufy’s Omni S2 enters that moment with a promise that feels personal: it’s built to handle pet hair while aiming to keep odors from lingering. After weeks of use. the reviewer says the roller mop does not get smelly. and that the dock and robot are efficient at washing and drying it after each cleaning.
The Omni S2’s design is tall. and its dock is “much taller than most robot vacuum and mop combos with a hands-free dock.” That shape comes with a practical downside—there’s also a drawback in upkeep: the water needs emptying and refilling more often than most hands-free combination models. The reviewer reports emptying the dirty water tank and refilling the clean water tank about once every two or three cleanings.
Eufy, though, made a specific change from the prior Omni S1. With the S1, the detergent container ballooned as it filled with air when it was emptied, which caused issues with the clean water tank. The Omni S2 repairs that with a vent on the top that allows airflow as the liquid empties.
On the cleaning power side, the upgrade is blunt. Eufy increased suction power from 8,000Pa on the predecessor to 30,000Pa on the Omni S2. The reviewer says it shows—especially on carpets—where it goes deep into carpet fibers and removes sand. dirt. and pet hair left behind by many other robot vacuums. It also performs very well on hard floors, and on both short-pile and medium-pile carpet.
Odor control is where the Omni S2’s engineering becomes most visible. Eufy includes a fragrance diffuser. a feature the reviewer initially viewed skeptically as something “frivolous. ” but says it proved useful from the first time it was used. Inside the robot, Eufy built a five-layer filtration system that culminates in the diffuser. The reviewer describes how the robot vacuum sucks up dust. hair. debris. dander. and other allergens into the dustbin; air then flows through five layers of filtration as it exits the vacuum and passes through the diffuser. expelling fresh-smelling. clean air as the robot moves around the house.
Eufy also doesn’t rely on “just perfume.” The dock makes hydrolyzed water to clean and disinfect hard floors as it moves.
Navigation is also a key part of the day-to-day feel. The reviewer said navigation is pretty good even though the model does not have a spinning LIDAR component protruding from the top. Early sessions may bump into furniture or walls for the first two or three cleanings. but the robot learns its surroundings with experience. Ultimately, it maps accurately and avoids the chaotic spinning search for its place that some robots perform.
For the mopping. the reviewer called it “the best robot mop I’ve ever used.” The roller mop is described as cracked so it cleans “almost as well as a person mopping your floors. ” reaching edges and leaving “every single inch” clean. It exerts 15N of downward pressure to remove dried spills. and it’s a large roller mop—11.4 inches long—so it covers more area with each pass.
Inside the robot. mopping is described as fast and continuous: it spins six times per second. continuously spraying clean water and scrubbing as it rolls over the floor. Even after weeks. the reviewer says the roller mop does not get smelly. which they connect to how efficiently the dock and robot wash and dry it after each cleaning.
Battery performance is the other place where expectations need adjusting. The Omni S2’s battery lasts around 150 minutes, described as mid-to-low end among comparable robot vacuums. That matters for larger areas. where it may stop about three-quarters of the way through an entire single-story home and return to charge.
Still, the reviewer gives a grounded example: the robot can vacuum an entire 900-square-foot first floor. It only requires going back to charge if suction power is set to the max level while mopping, and it’s typically only when there are about 10 or 15 minutes left.
All of this lands at a high price. The Eufy Omni S2 is priced at $1,600, which the reviewer frames as high-end—but also as a robot vacuum and mop they expect to keep for years.
The reviewer also says the Eufy Omni S2 wins the ZDNET Editors’ Choice award for being an exceptional robot vacuum and mop in both controlled experiments and home tests, and that Eufy perfected the design by correcting shortcomings from the S1 model.
