What the differences mean

Dock

The iRobot Roomba 505X comes with an AutoWash dock that empties the bin, washes and dries the mop pads. The iRobot Roomba 105 sits on a simple charger: nothing is emptied or washed for you.

Mopping

The iRobot Roomba 505X vacuums and mops in the same run, takes detergent and lifts its pads over carpet. The iRobot Roomba 105 does not mop.

Runtime

180 minutes on the iRobot Roomba 505X against 120 on the iRobot Roomba 105, which is the recharge stop Roomba 105 owners complain about in larger homes.

Suction

Both are rated at 7000Pa, so the step up buys the dock, not pickup power.

Smart home

Both work with Alexa and Google Home. The iRobot Roomba 505X adds Apple HomeKit, SmartThings, Home Assistant and Matter, and joins 5 GHz networks.

What owners say

Owners of both Roombas praise the same LiDAR mapping, room by room and in organized rows, and both groups say pet hair and daily dust are handled well. iRobot Roomba 505X owners single out how little they touch the machine, since the AutoWash dock empties and washes the pads for weeks, but they warn that the cleaning cycle runs loud, that Wi-Fi pairing or mapping can take a reset or two and that dark floors can confuse the cliff sensors. iRobot Roomba 105 owners talk about value for money and simple scheduling, and their complaints are a runtime that falls short in larger homes, weaker pickup on thicker carpet and a few battery or navigation faults after some months.
