Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official iRobot site.
2026 verdict
Is the X worth anything extra? Not on the spec sheet: the iRobot Roomba 105 is the pick of these two robot vacuums, because it matches the iRobot Roomba 105X feature for feature and is usually the lower priced of the pair.

Both use LiDAR to map multiple rooms and clean in rows, detect obstacles and cliffs, honor no-go zones, rate 120 minutes of battery, measure 335 mm across and connect over 2.4 GHz Wi-Fi to Alexa and Google Home. Neither mops, neither has a self-emptying dock, and both carry a one-year warranty. The two differ only in model number (Q312020 against Q314020), so buy whichever one costs less the day you shop, which is most often the iRobot Roomba 105.

What the differences mean

Model number

The iRobot Roomba 105 is model Q312020 and the iRobot Roomba 105X is Q314020. Every spec the catalog tracks, from battery and mapping to smart home support, is the same on both.

Weight

Listed at 2790 g and 6.27 lb, the two weigh essentially the same, and they share the same 335 mm footprint and 104 mm height, so both fit under the same furniture.

Price

With identical hardware on paper, the price is the one thing that separates them in practice, and the iRobot Roomba 105 is usually the cheaper listing.

Which one to buy if

  • you just want the cheaper of two identical robots
    iRobot Roomba 105

    The iRobot Roomba 105 matches the 105X on every tracked spec and usually costs less.

  • the iRobot Roomba 105X is on sale below the 105
    iRobot Roomba 105X

    Nothing on the spec sheet favors the 105, so the lower price decides.

  • you need a robot that also mops or empties itself
    iRobot Roomba 105

    Neither does, so look at another model; between these two, the iRobot Roomba 105 is the lower priced vacuum.

What owners say

Owners of the two Roombas describe the same robot. Both groups praise LiDAR mapping that cleans in tidy rows instead of bumping around, and suction that pulls up more pet hair than they expected for the money, and both name the same main weakness: in a larger home the battery runs down and the robot has to recharge mid-clean before finishing. iRobot Roomba 105 owners add that the bin lasts a few days between emptying and that it is quieter than their old robot, while a few report weaker pickup on thicker carpet and battery or navigation faults after some months. iRobot Roomba 105X owners talk more about sending it to one room at a time and warn that loose cords and door mats need clearing first, with a few seeing the side brush wear after repeated snags.

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.

Frequently Asked Questions

What is the difference between the iRobot Roomba 105 and the iRobot Roomba 105X?

On the spec sheet, only the model number: Q312020 for the iRobot Roomba 105 and Q314020 for the iRobot Roomba 105X. Both have LiDAR mapping, 120 minutes of rated battery, the same size and the same Alexa and Google Home support.

Which is better overall: iRobot Roomba 105 or iRobot Roomba 105X?

Neither is better as a machine, so the iRobot Roomba 105 wins by usually costing less. If the iRobot Roomba 105X is cheaper when you shop, buy that one instead.

Do the iRobot Roomba 105 and the iRobot Roomba 105X mop or self-empty?

No. Both are vacuum-only robots with no mopping, and neither comes with a self-emptying dock, so the bin is emptied by hand.

Do the iRobot Roomba 105 and the iRobot Roomba 105X work with Home Assistant or Matter?

No. Both connect over 2.4 GHz Wi-Fi and work with Alexa and Google Home, but not with Matter, SmartThings or Home Assistant, whose Roomba integration does not cover these newer models.

Who should buy the iRobot Roomba 105 or the iRobot Roomba 105X?

Budget buyers and pet owners in small to medium homes with hard floors and light carpet who want mapped, room-by-room vacuuming and do not need mopping or a self-emptying dock.
