The iRobot Roomba 505X is the robot vacuum that makes the step worth it. Suction stays 7000Pa on both, but the 505X adds a 180 minute battery against 120, a dock that empties, washes and dries, and Matter, Apple Home and 5 GHz Wi-Fi. The iRobot Roomba 105 Combo still mops on a LiDAR map, and it is the more affordable robot you maintain by hand. Choose the iRobot Roomba 505X when the dock should do the chores, and the iRobot Roomba 105 Combo for a smaller hard-floor routine.

What the differences mean

Dock

The iRobot Roomba 505X empties the bin and washes and dries the pads, and it lifts the mop for carpet. The iRobot Roomba 105 Combo mops, but it does not wash, dry, lift or self-empty. Same 7000Pa suction, different amount of work left for you.

Battery

The iRobot Roomba 505X is rated for 180 minutes and the iRobot Roomba 105 Combo for 120 minutes. Both recharge in the same window, 4.5 hours against 5 hours, so the longer rating is the part you feel.

Smart home

The iRobot Roomba 505X supports Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter, on 2.4 and 5 GHz. The iRobot Roomba 105 Combo supports Alexa and Google Home only, on 2.4 GHz.

What stays the same

Both use LiDAR, both map several rooms, both offer no-go zones, a child lock and scheduling, and both list 7000Pa. The step up is the dock and the platforms, not a bigger vacuum motor.

What owners say

Owners of both Roombas like LiDAR that cleans in a path instead of bouncing, and both mention a setup that can take patience. iRobot Roomba 105 Combo owners say daily dust and hair are handled, and they complain about a rocky first map, getting stuck at rugs, a mop that avoids carpet instead of lifting, and a bin they empty. iRobot Roomba 505X owners single out weeks of not touching the pads and solid results on hardwood, tile and everyday carpet, and they complain that a deep cycle is loud and that the first Wi-Fi pairing sometimes needs another try.

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.
