What the differences mean

Station versus a bin

The Roborock Saros 20 self-empties into a 2.5 L dock bin, mops, lifts the pads, washes and dries them and holds 4 L of water. The iRobot Roomba 105X does not mop and does not self-empty, so the onboard bin is a manual chore. Its onboard capacity is not documented. The daily difference is whether you open the robot after a run or leave that to the dock.

Runtime

The Roborock Saros 20 is rated for 200 minutes and about 2.5 hours to charge. The iRobot Roomba 105X is rated for 120 minutes and about 5 hours to charge. Both recharge themselves. Owners of the iRobot Roomba 105X say larger homes stop mid-clean, which is the practical reading of that 120 minute rating.

Wi-Fi and assistants

The Roborock Saros 20 uses 2.4 GHz and 5 GHz and lists Alexa, Google Home, Apple HomeKit, SmartThings, Home Assistant and Matter. The iRobot Roomba 105X uses 2.4 GHz only and lists Alexa and Google Home but not Apple HomeKit, SmartThings, Home Assistant or Matter. A 5 GHz network, or an Apple home, points to the Roborock Saros 20.

Body

The Roborock Saros 20 measures 79.8 mm tall and weighs 5.05 kg. The iRobot Roomba 105X measures 104 mm tall and weighs 6.27 lb. Both use LiDAR, cliff sensors and no-go zones. The shorter body is the Roborock Saros 20, which is what gets it under furniture the taller vacuum cannot clear. Suction on the iRobot Roomba 105X is not documented, so it is not compared here.

What owners say

Owners of the Roborock Saros 20 describe a map that labels rooms quickly and a dock that washes pads in hot water, and they like how quiet an overnight run feels. Owners of the iRobot Roomba 105X describe everyday hair pickup that surprised them and the relief of sending the robot to one room, such as a litter area. Roborock Saros 20 owners complain that some thresholds still stop the arm and that detergent is an extra purchase. iRobot Roomba 105X owners complain that a large home needs a recharge before the floor is done and that cords and mats tangle the brush. One group is living with a station. The other is living with a bin.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
