Its station empties the robot, washes the mop with hot water, dries it and refills clean water, so nothing about the hands-off routine is compromised by the longer battery. On a larger floor plan it finishes in one pass where the Roomba goes back to charge. The iRobot Roomba 505X answers on ecosystem: it supports Apple HomeKit, Matter and IFTTT alongside Alexa and Google Home, where the Eufy Omni C28 covers the two assistants only. In an Apple household, or one built on Matter routines, that outweighs the extra runtime. Choose the iRobot Roomba 505X for HomeKit, Matter and IFTTT, and the Eufy Omni C28 for double the runtime with a fully automatic dock.
