Its dock empties the bin and washes, dries and doses detergent for the mop, and at 79.8mm it is slim enough to clean under low furniture. The iRobot Roomba 105X is the lower-cost pick and still delivers LiDAR mapping and room-specific cleaning with Alexa and Google Home. Choose the Roborock Saros 20 Sonic for a hands-off vacuum and mop, and the iRobot Roomba 105X for mapped vacuuming alone.

What the differences mean

Mopping

The Roborock Saros 20 Sonic mops, lifts the mop on carpet and washes and dries it at the dock. The iRobot Roomba 105X has no mop, so it cannot clean hard-floor spills or film.

Battery life

Rated for 190 minutes against the iRobot Roomba 105X's 120, the Roborock Saros 20 Sonic covers a larger floor plan in one pass before returning to recharge.

Wi-Fi and connectivity

The Roborock Saros 20 Sonic adds 5GHz Wi-Fi, where the iRobot Roomba 105X runs on 2.4GHz Wi-Fi only. Both have Bluetooth.

Smart home reach

The Roborock Saros 20 Sonic supports Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. The iRobot Roomba 105X stops at Alexa and Google Home.

What owners say

iRobot Roomba 105X owners call it a strong value vacuum: LiDAR mapping cleans in organized rows, room-specific cleaning and no-go zones let them target one space at a time, and it pulls up more pet hair than they expected for the price. The app, remote start and scheduling get repeated credit, and several owners describe it as a clear upgrade from an older bump-and-go robot. They also warn that the battery can run short in a larger home and force a mid-clean recharge, that loose cords and door mats can tangle it unless the floor is cleared, and that there is no mopping or self-emptying, with 2.4GHz Wi-Fi only.
