2026 verdict
Mopping and a long battery put the Eufy Omni C28 ahead of a vacuum-only dock.
It mops, washes, dries, lifts and doses detergent, at 15,000 Pa and 251 minutes, and it is the more affordable robot vacuum. The iRobot Roomba Max 705 self-empties and does not mop. It lists Apple Home, SmartThings, Home Assistant and Matter, plus 5 GHz Wi-Fi, which the Eufy Omni C28 does not match. Runtime on the Roomba is 120 minutes at 13,000 Pa. Pick the Eufy Omni C28 to vacuum and mop. Pick the iRobot Roomba Max 705 if you only vacuum and need Apple Home.

What the differences mean
Mopping
The Eufy Omni C28 mops, washes and dries the roller, lifts it for carpet and doses detergent, with a 2.2 L water tank. The iRobot Roomba Max 705 does not mop. If a damp floor is part of the week, the Roomba leaves that job to you, however good the vacuum dock is.
Runtime and suction
The Eufy Omni C28 is rated for 251 minutes at 15,000 Pa and charges in 3.5 hours. The iRobot Roomba Max 705 is rated for 120 minutes at 13,000 Pa and charges in 4.5 hours. Both self-empty. The Eufy dock bag is 3 L. The Roomba dock volume is not published.
Smart home
The iRobot Roomba Max 705 lists Apple Home, SmartThings, Home Assistant and Matter, and it joins 5 GHz Wi-Fi. The Eufy Omni C28 lists Alexa, Google Home and Home Assistant, with Bluetooth, on 2.4 GHz only. It does not list Apple Home or Matter. That is the Roomba's real reason to win a buyer back.
Docks, different sizes
The Eufy Omni C28 dock is 437 x 352.5 x 430 mm and weighs 6.15 kg, because it holds water. The iRobot Roomba Max 705 dock is 213 x 172 x 290 mm and 2.3 kg, a vacuum base rather than a mop station. The robots themselves are a similar footprint. The Eufy publishes 54.89 dB. Roomba noise is not documented.
Which one to buy if
- you want vacuuming and mopping from one station
The Eufy Omni C28 washes, dries, lifts and doses detergent for 251 minutes. The iRobot Roomba Max 705 cannot mop.
- you need Apple Home and you only vacuum
The iRobot Roomba Max 705 lists Apple Home, SmartThings and Matter, and its self-empty dock is the smaller vacuum base.
- a large floor should finish on one charge
251 minutes against 120 is the runtime gap, with 15,000 Pa against 13,000 Pa, at the lower price.
- the dock has to stay small
The iRobot Roomba Max 705 base is about 213 x 172 x 290 mm. The Eufy Omni C28 station is a full mop dock, much wider and taller.

What owners say
Owners of the Eufy Omni C28 and the iRobot Roomba Max 705 both like a dock that means they stop emptying a bin every day, and then they describe different machines. Eufy Omni C28 owners single out a roller that rinses as it scrubs, with dirty water as the proof, and tangle-free brushes on pet hair. Drying that takes hours is the common complaint. iRobot Roomba Max 705 owners who came from older Roombas single out faster LiDAR maps, quieter runs and pet hair on carpet, and an AutoEmpty dock they leave for weeks. Their friction is Wi-Fi setup when a password has special characters, and the hard stop that there is no mop.
