What the differences mean

Suction and runtime

The Eufy Omni C28 is rated at 15,000 Pa and 251 minutes, recharging in about 3.5 hours. The iRobot Roomba Plus 505 is rated at 7,000 Pa and 180 minutes, recharging in about 4.5 hours. Both return to the dock and both list carpet cleaning. On a large hard-floor plan the extra hour of rated runtime is the difference, and 15,000 Pa is the higher pull for hair in edges and pile.

Mop hardware

The Eufy Omni C28 uses a roller the station washes and hot-air dries, and it doses detergent automatically, with a 2.2 L water tank. The iRobot Roomba Plus 505 uses pads the dock washes and dries, lists detergent compatibility, and has no automatic dispenser. Its water tank capacity is not documented. Both lift the mop for carpet and both self-empty. The Eufy Omni C28 dock bin is 3 L.

Smart home and Wi-Fi

The iRobot Roomba Plus 505 lists Alexa, Google Home, Apple HomeKit, SmartThings, Home Assistant and Matter, on 2.4 GHz and 5 GHz. The Eufy Omni C28 lists Alexa, Google Home and Home Assistant, has Bluetooth as well, and does not list Apple HomeKit, SmartThings or Matter. It is 2.4 GHz only. If the home is already on Apple HomeKit, the iRobot Roomba Plus 505 is the robot that joins it today.

Noise, where it is known

The Eufy Omni C28 is rated at 54.89 dB. Noise on the iRobot Roomba Plus 505 is not documented, so the spec sheet does not crown a quieter robot. Owners of the iRobot Roomba Plus 505 still describe the dock cycle as loud, which is a report, not a decibel figure. Both have a child lock, scheduling and real-time tracking.

What owners say

Owners of the Eufy Omni C28 and the iRobot Roomba Plus 505 both like a dock that takes the daily chores away, and both bring up pet hair. Eufy Omni C28 owners single out a roller that scrubs while it rinses itself, and they complain that drying can take hours and that cables and clutter still trap it. A few received a unit with a bad water compartment. iRobot Roomba Plus 505 owners single out a map that shows up quickly and hair pickup on mixed floors, and they complain that the self-clean cycle is loud and that some units later develop bumper or dock-finding faults. Neither group calls the station optional.
