Early Black Friday pricing has landed on Eufy’s HydroJet robot vacuums, and three Omni models are down between 37% and 43% at Amazon right now. Each one vacuums, mops with a roller that washes itself mid-clean, and docks in a station that empties its dust, refills its water, and dries the mop when the run ends. The savings run from $340 to $400 per machine, and all three ship from Anker EufyHome, Eufy’s own Amazon storefront.

Choosing between them comes down to suction and one extra trick. The C28 pairs the gentlest motor with the lowest price. The E25 steps up to stronger suction and camera-based obstacle avoidance, and the E28 adds a portable deep cleaner inside the dock for stains the robot can’t reach. Order here follows the size of the cut, not the price tag.

Ownership adds the usual consumables: dust bags, roller mops, and filters, all sold as kits through Eufy’s store.

Three machines, one idea: never mop with a dirty mop.

1 Eufy Omni C28, the deepest cut of the three

At $459.99 against a $799.99 list price, the C28 takes 43% off, the largest cut in this group. We wrote up the C28 at $499.99 when it launched this fall, and the price has slid another $40 since. The money buys the full HydroJet treatment: a roller mop that sprays clean water from 24 ports, scrubs under steady pressure, scrapes itself clean, and never drags the last room’s dirt into the next one.

Suction runs 15,000 Pa, the softest motor here by a wide margin, but DuoSpiral brushes keep hair from wrapping the roller, and a CornerRover arm swings out for the edges a round body skips. The roller turns at 270 RPM, the fastest spin of the three, which is how the cheaper machine still scrubs like the flagship system.

The 5-in-1 Omni Station empties dust into a 3L bag rated for up to 75 days, washes and hot-air dries the mop, refills the clean tank, and holds the dirty water. A vacuum-and-mop run lasts about 123 minutes. The dock stands about 17 inches tall.

Pet hair and hard floors are this one’s home turf. It skips the camera smarts of its siblings to hit the price, with navigation running on Eufy’s iPath 2.0 system instead, and mostly-carpet homes will feel the smaller motor. A white version exists if the black finish clashes with the room.

2 Eufy Omni E25, the strongest cleaner here

$599.99 buys the E25, down from $999.99 for a clean 40% off and $400 saved. It’s the strongest straight cleaner in the group, with 20,000 Pa of suction and an RGB camera running AI.See obstacle avoidance, so it steers around shoes, cords, and chew toys instead of pushing them across the floor. Eufy rates it at 57 dB in operation, and it lands at the middle price of the three.

Its HydroJet roller spins at 180 RPM and cleans itself as it mops. The station handles the rest of the routine: dust lands in a 3L bag rated for up to 75 days, the mop gets washed after every session and dried with hot air, and detergent dispenses itself for up to six months.

One fill of the clean-water tank covers up to 5,000 square feet, and the battery runs about 125 minutes with vacuuming and mopping together, stretching to 216 minutes on vacuum alone. At 4.4 inches tall, it slides under most sofas and beds, and the CornerRover arm it shares with the C28 reaches baseboard dust the body can’t reach on its own.

The app side carries its weight too: no-go zones around a pet’s feeding station or a play area, schedules, and run tracking from your phone while the robot works through the house on its own. For a mixed-floor house with clutter on the ground, this is the pick of the three, giving up nothing to the E28 on floors; the gap is only the spot cleaner.

3 Eufy Omni E28, with a carpet cleaner in the dock

$629.99 gets the E28, down from $999.99, a 37% cut. The $30 premium over the E25 buys exactly one thing: the FlexiOne portable deep cleaner built into the station. Lift it out and it works like a spot cleaner on carpet stains, stair spills, and fabric messes that sit outside the robot’s route.

Under that trick, the hardware matches the E25: 20,000 Pa of suction, the HydroJet roller mop, DuoSpiral detangle brushes, and a station that empties, washes, dries, and refills. Run times match too, 125 minutes of combined cleaning or 216 minutes vacuum-only.

Two limits from Eufy’s own FAQ are worth knowing before you pay the premium. The portable cleaner handles liquid stains only.

Hair and solid messes still need a vacuum pass, and Eufy rates the robot for carpet pile up to about an inch. Between jobs it docks back inside the station, no separate machine to store.

Buy it if your stairs, sofa, or a pet’s favorite rug spot keeps a spot cleaner employed. Everyone else gets the same floor cleaning from the E25 for $30 less, which is the smarter buy for a flat, single-floor home while the early Black Friday pricing holds.
