It mops, washes, dries and lifts the pads, self-empties, runs 180 minutes and lists Apple Home, SmartThings, Home Assistant and Matter. The iRobot Roomba 105X is vacuum-only, with no self-empty dock, a 120 minute runtime and Alexa and Google Home only. It is the more affordable of the two Roomba robots. Suction on the 105X is not published, so the 505X figure of 7,000 Pa is not a scored win. Pick the iRobot Roomba 505X when the dock should do the chores. Pick the iRobot Roomba 105X for mapped vacuuming at a lower price.

What the differences mean

Mopping dock

The iRobot Roomba 505X mops, washes and dries the pads, lifts them for carpet and self-empties. The iRobot Roomba 105X does not mop and does not self-empty. Moving from one to the other is mostly buying that station, not a different navigation idea. Both already map with LiDAR and set no-go zones.

Runtime and Wi-Fi

The iRobot Roomba 505X is rated for 180 minutes, charges in 4.5 hours and joins 5 GHz Wi-Fi. The iRobot Roomba 105X is rated for 120 minutes, charges in 5 hours and is 2.4 GHz only. Both list Bluetooth. A larger floor is where the extra hour shows up.

Smart home

The iRobot Roomba 505X lists Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. The iRobot Roomba 105X lists Alexa and Google Home only. If the rest of the house is on Apple Home, the 105X cannot join it.

Size and suction

The iRobot Roomba 505X measures 358 x 351 x 107 mm and weighs 9.44 lb, and it publishes 7,000 Pa. The iRobot Roomba 105X measures 335 x 335 x 104 mm and weighs 6.27 lb. Its suction is not published, so do not treat 7,000 Pa as a win. The 505X is simply the heavier robot with the dock.

What owners say

Owners of the iRobot Roomba 105X and the iRobot Roomba 505X both like sending a LiDAR robot to a room instead of watching it bounce, and both mention pet hair. iRobot Roomba 105X owners single out everyday suction that surprised them for the price, and they flag a recharge in larger homes plus tangles on loose cords. They empty the bin themselves. iRobot Roomba 505X owners single out the AutoWash dock doing the emptying, refilling and pad washing for weeks, and solid hardwood and tile. They complain that deep-clean mode is loud and that the first Wi-Fi pairing can need patience. The dock, not the map, is what the second group keeps describing.

Upgrading from the iRobot Roomba 105X?

Moving up from the iRobot Roomba 105X to the iRobot Roomba 505X buys the station and the protocols, not a new way of mapping. You gain mopping with washing, drying and carpet lift, a self-empty dock, 5 GHz Wi-Fi, a 180 minute runtime against 120, and Apple Home, SmartThings, Home Assistant and Matter. LiDAR, no-go zones, Alexa and Google Home are already on the 105X. Suction on the 105X is not published, so do not assume the step up is a big Pa jump. The 505X publishes 7,000 Pa. Skip the move if you only vacuum, you are happy emptying a bin, and you do not need Apple Home.
