Of the 6 eufy robot vacuums Amazon sold new, from $170 to $1,300, 4 have a self-emptying dock and 4 have a dock that washes the mop; eufy publishes a threshold-climb figure for 5 and a mop-lift figure for 1.

Every eufy robot vacuum we track
Sorted by Amazon price. Each figure links to the eufy page it was read from. “Not published” means eufy leaves it off that model’s page; we never borrow a figure from a sister model.

eufy puts some figures only in the comparison table on its Omni C28 page. The E25 and E28 heights and climb come from that table, each from its own column. The C28 and E35 pages list no height or climb for those two models.

eufy models we left out
eufy’s site calls two of them the Omni E25 and Omni E28; the Amazon listings say E25 and E28. We add a model only after we have read its limits on eufy’s own site (eufy.com).
What eufy publishes, and what it leaves out
A figure the maker leaves off is a figure you cannot check before you buy. This is how many of the 6 eufy models on Amazon carry each figure on eufy’s own page, and the range where they do.
| Figure | eufy models on Amazon with it | Range |
|---|---|---|
| Threshold climb | 5 of 6 | 16 to 35 mm (maker’s numbers; the table says single or double step) |
| Robot height | 4 of 6 | 2.85 to 4.4 in |
| Mop lift | 1 of 6 | 10.4 mm |
| Days the dock holds | 3 of 6 | 60 to 75 days |
| Runtime a charge | 2 of 6 | 100 to 101 min |
| Suction | 6 of 6 | 2,000 to 30,000 Pa |
| Warranty | 1 of 6 | 1 years |
Bare unit or bundle on Amazon
Search Amazon for a eufy and the bare unit can sit next to bundles with extra parts or a protection plan. We link only the bare unit, so the price you compare is the unit itself.
These are the eufy bundle listings we did not link when we checked on November 2, 2026:
- eufy Official Accessory Kit, Compatible for Omni E25/E28 | Side Brush, Filter, Roller Brus: $52
A bundle can still be the right buy if you would buy its extras anyway. Compare its price with the bare unit plus the parts you want.
How to choose a eufy
Thresholds first. Measure your tallest door strip or rug edge. A robot that cannot climb it will stop there every time. The highest eufy figure on Amazon is 35 mm (single step, maker's number), on the eufy Omni S2.
Then the dock. A self-emptying dock empties the robot into a bag or bin you deal with every month or two. A washing dock also rinses the mop, so you stop handling wet pads. The table says which is which.
Then the mop. A flat pad drags behind the robot. Two spinning pads, a roller or a track mop scrub. If you have rugs, look for a mop-lift figure: it tells you how high the wet mop rises when the robot crosses a rug.
Then height. Measure the gap under your lowest bed or sofa. The robot needs more room than its own height to get under.

What refills cost a year
The refill column uses eufy’s own parts at Amazon prices, times how often eufy says to replace them. A part counts only when eufy gives a replacement interval and its own part is on Amazon under a listing that names the model. Where either is missing, the cell says so. Each model page shows the math row by row.

Which eufy robot vacuum should I buy?

What is the difference between eufy models?
Mostly the dock and the mop. 4 of the 6 on Amazon empty themselves into the dock, and 4 have a dock that washes the mop. Threshold climb runs from 16 to 35 mm where eufy gives a figure (maker's numbers; the table says which are single or double step). The table has every figure with its source.
Which eufy climbs the highest threshold?
The eufy Omni S2: up to 35 mm (single step, maker's number). eufy gives a climb figure for 5 of the 6 models on Amazon.
Which eufy is the thinnest?
The eufy 11S Max at 2.85 in, by eufy's figure, of the 4 with a published height.

When we checked on November 2, 2026, Amazon or eufy sold these new: eufy 11S Max, eufy C28, eufy E25, eufy E28, eufy Omni C20, eufy Omni S2. Each one is in the table above with its Amazon price.
Which eufy is best for pet hair?
eufy names an anti-tangle brush for the eufy C28, eufy E25, eufy E28, eufy Omni C20 and eufy Omni S2. A brush that does not wrap hair saves you cutting it free every week. For a cross-brand pick on pet hair and hardwood, see our pet hair page.
Which eufy is best if I have rugs and want to mop?
Look for a published mop lift. eufy gives one for the eufy Omni C20 (10.4 mm). A higher lift keeps the wet mop off a thicker rug.
What warranty does eufy give?
1 year: the eufy 11S Max. These are eufy's published terms; models not named here have no warranty line on the page we read.
How much do eufy refills cost a year?
eufy E25: $24 for the parts we could price; eufy E28: $24 for the parts we could price. That is eufy's own parts at Amazon prices, replaced as often as eufy says.
