What the differences mean

Mop and self-empty

The iRobot Roomba Plus 505 mops, lifts the pad on carpet, and the dock empties the bin and washes and dries the mop. The iRobot Roomba 105X does none of that: no mop, no wash, no dry, no self-empty. You tip its bin out yourself. That is the whole product gap, not a small settings difference.

Battery and charge

The iRobot Roomba Plus 505 is rated for 180 minutes and charges in about 4.5 hours. The iRobot Roomba 105X is rated for 120 minutes and charges in about 5 hours. Owners of the 105X already say a large home forces a mid-clean recharge. The longer rating on the Plus 505 is what pushes that moment later.

Wi-Fi and smart home

The iRobot Roomba Plus 505 supports 5 GHz Wi-Fi, Apple Home, SmartThings, Home Assistant and Matter, plus Alexa and Google Home. The iRobot Roomba 105X is 2.4 GHz only and supports Alexa and Google Home, not Apple Home, SmartThings, Home Assistant or Matter. A dual-band router and a Home app are both reasons to leave the 105X.

Body size

The iRobot Roomba 105X is 335 mm across and 104 mm tall. The iRobot Roomba Plus 505 is 357 by 351 mm and 106 mm tall, at 4.3 kg, so the mop robot and its dock take more floor space. Both still use LiDAR and a child lock. Next to self-emptying and a washed mop, that size gap is the smaller decision.

What owners say

Owners of both like LiDAR that cleans room by room instead of bouncing, then they live with different chores. iRobot Roomba 105X owners say everyday suction surprises them on pet hair and mixed floors, and they like a simple schedule, while they warn that the battery falls short in larger homes, cords and mats tangle it, and they still empty the bin by hand. iRobot Roomba Plus 505 owners single out an AutoWash dock that empties the bin and washes and dries the pads, strong pet-hair pickup on carpet and hard floors, and obstacle avoidance around cords, and they complain the dock cycle is loud and that navigation or bumper-stuck errors show up for some units after a few months.

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.
