The eufy Omni S2 is the eufy robot vacuum to buy for most people. It has the best shopper rating among eufy models in our listings, 4.48 stars from 27 Google Shopping reviews, and it is the only one that lists a HEPA filter. If you want one robot that also mops hard floors, get the eufy E28 instead: its listing names a roller mop with HydroJet System and 20,000 Pa suction, and it has the lowest price of the three eufy models. As of October 2026 we list three eufy models, one vacuum-only and two vacuum-and-mop combos. Card prices are live.
Our Picks: The Best eufy Robot Vacuum for Each Need
Each pick is labeled by the buyer need its listing supports. With only three eufy models in our data, two of them earn a label.
Best overall: eufy Omni S2
Buy this if your home is mostly carpet or you have allergies, and you want a vacuum-only robot with no mop to manage.
- HEPA filter: It is the only eufy listing here that names one.
- Rating: 4.48 from 27 Google Shopping reviews. That is the strongest rating in the lineup, and the only one backed by more than a handful of reviews.
Versus the E28: You give up mopping and the E28's listed 20,000 Pa suction. You gain HEPA filtration and a real rating record.
Caveats:
- It is the top-priced eufy model here.
- Its listing gives no suction figure, base type or voice-assistant support.
- 27 reviews is still a small sample.
Best for mopping hard floors: eufy E28
Buy this if your floors are mostly hard surfaces and you want vacuuming and mopping in one machine.
- Mop system: Its title names a roller mop with HydroJet System.
- Suction: 20,000 Pa, the only suction figure listed for any eufy model in our data.
- Capacity: 0.66 gal as listed. The listing doesn't say whether that refers to the bin or the base.
Versus the Omni E35: Both are combos, but the E28 lists suction, capacity and a named mop system, while the E35 lists none of these. The E28 also costs less.
Caveat: Its 3.67 rating comes from only 3 reviews, so treat it as unproven. No HEPA filter or base is listed either.
The third model, the Omni E35, appears in the comparison table below. Its listing doesn't support a pick label.
How the eufy Lineup Is Organized
Every eufy model in our data is tagged premium. That places the whole brand in the upper price bracket of the robot vacuums we track. There is no entry-level eufy option here. Within that bracket, the three models fall into three steps:
- Lower (eufy E28): A vacuum-and-mop combo. It is the only eufy listing with suction (20,000 Pa), capacity (0.66 gal) and a named mop system.
- Middle (eufy Omni E35): Also a combo, but its listing names nothing beyond "robot vacuum and mop combo." It has 3 reviews.
- Top (eufy Omni S2): Vacuum-only, and the only one of the 3 eufy models to list HEPA. It has 27 reviews.
What the eufy listings leave out matters as much as what they include:
- 0 of 3 list a self-empty or bagless base.
- 0 of 3 list voice-assistant support.
- 0 of 3 carry a pet designation.
- Two titles share "Omni," but the listings don't explain what it means, so don't assume it guarantees any dock feature.
Most worth paying for: HEPA filtration, if anyone in your home has allergies. It is the one health-related feature the data confirms, and only the Omni S2 has it.
Most buyers can skip: Stepping from the E28 up to the Omni E35. It costs more but documents less.
eufy Robot Vacuums Compared Side by Side
For eufy, the rating column matters most, because review counts range from 3 to 27 and decide how much any score can be trusted. We dropped the base, suction, HEPA and voice-assistant columns because eufy's listings fill them for one model at most. A single column shows whatever each listing does state.
| Model | Best for | Type | Price position | Shopper rating (reviews) | Specs as listed |
|---|---|---|---|---|---|
| eufy Omni S2 | Best overall | Vacuum-only | Top (within eufy) | 4.48 (27) | HEPA Filter |
| eufy E28 | Hard-floor mopping | Vacuum + mop | Lowest (within eufy) | 3.67 (3) | 20,000 Pa; Roller Mop with HydroJet System; 0.66 gal |
| eufy Omni E35 | Skip: costs more than E28, lists less | Vacuum + mop | Mid (within eufy) | 3.67 (3) | Not listed |
The Omni S2 is the clear overall pick. The Omni E35 is the most poorly documented model: it has the same 3-review rating as the E28, sits higher in price and shows no specs. For carpet and allergy homes that don't need mopping, the eufy Omni S2 is the one to buy.
Vacuum-Only or Vacuum-and-Mop: Which eufy Type to Get
Two of the three eufy models in our data are vacuum-and-mop combos, and one is vacuum-only.
What the combos list:
- The E28 names its mop: a roller mop with HydroJet System. It also lists 20,000 Pa suction and 0.66 gal capacity.
- The Omni E35's listing confirms only that it is a cordless robot vacuum and mop combo.
- Neither combo lists a surface type, a carpet-handling feature, a self-cleaning mop base or a water-tank size. Check those on the product page.
Who a eufy combo suits: Homes with mostly hard floors that pick up light daily grime, such as kitchen spills, entry dust and paw prints. For those homes, a mopping robot saves a chore. Between the two combos, the E28 is the better-documented choice and the lower-priced one.
Who should save the money: Homes that are mostly carpet and rugs gain little from a mop. Without listed carpet handling, there's a risk of damp rugs. Those buyers should choose the vacuum-only Omni S2.

Owning a eufy Robot Vacuum: Bags, Filters, Parts and Support
What the listings say:
- Base: None of the three eufy listings in our data names a base type, so we can't tell you whether any of them uses bags, empties into a bagless bin, or has no dock at all.
- Filter: Only the Omni S2 lists a HEPA filter.
- Capacity: Only the E28 lists one, at 0.66 gal, and the listing doesn't say what it refers to.
What you'll keep buying:
- HEPA filter (Omni S2): HEPA filters typically need periodic replacement to keep working as intended, so plan on buying them.
- Mop rollers (combos): The E28's roller mop will wear over time like any mop, so you'll want spare rollers.
- Brushes (all models): Side brushes and main brushes are standard wear items on every robot vacuum.
- Dock bags: If a model's dock turns out to be bagged, add bags to the list.
Our product feed currently has no eufy replacement parts. Confirm that parts are available before you commit. If you want a base that handles dirt disposal for you, compare dedicated self-emptying robot vacuums.
Check on eufy's official site before buying:
- The warranty term and what it covers
- App features and whether Alexa or Google Assistant is supported
- Whether filters, brushes, mop rollers and any dock bags are sold for your exact model
- What the "Omni" dock does on the Omni E35 and Omni S2

Who Should Skip eufy, and What to Buy Instead
eufy may not fit if any of these gaps matter to you:
- You want a lower price. There is no lower-priced eufy tier in our data. Shark's Matrix Plus is entry-level. It lists HEPA filtration, a bagless base, Alexa support and Sonic Mopping, and has 4.04 stars from 1,794 reviews.
- You want a self-emptying base and a proven track record. eufy's three models total just 33 reviews, and none lists a self-empty base. The Dreame L10s Ultra Gen 2 lists a base that handles dust disposal, water refilling and mop cleaning. It also carries a pet designation and has 4.59 stars from 2,699 reviews.
- You want HEPA without paying top tier. The Shark Navigator RV2110 is a vacuum-only, entry-level model that lists a HEPA filter. It has 5.0 stars from 427 reviews.
How We Picked
We drew on current product listings, spec fields, and Google Shopping shopper ratings with review counts, all as of October 2026. We weighed each model on four things:
- Fit for a specific need
- Spec evidence for that need
- Rating strength, including how many reviews back it
- Price position within eufy's lineup
This is a research guide, not hands-on testing. Card prices update live. Specs missing from listings are shown as "Not listed," never guessed. For picks across every brand, see our best robot vacuums across all brands.
Bottom Line: Which eufy Robot Vacuum to Buy
The eufy Omni S2 is the pick. It is the best-rated eufy model in our data and the only one that lists HEPA, which suits carpet and allergy homes. If you need mopping on hard floors, choose the eufy E28 instead, keeping in mind that its rating rests on just 3 reviews. If your budget is lower, or you want a self-emptying base with a long review record, the Shark and Dreame alternatives above fit better.
