iRobot Roomba 105X vs iRobot Roomba 115X Combo

Full Robot Vacuums comparison in 2026

Updated October 2026
Data from the official iRobot site.
2026 verdict
For a compact apartment, the iRobot Roomba 115X Combo is the more versatile robot vacuum of this pair.
It is the better reviewed of the two and adds two things the iRobot Roomba 105X leaves out entirely: a washable mop pad for hard floors and an AutoEmpty dock that seals debris in a bag for weeks. The iRobot Roomba 105X answers with the lower price and a longer single-charge runtime, and it is the simpler machine to own if you never want to deal with a mop. Both navigate with LiDAR, both map several rooms with no-go zones, and both stay on 2.4 GHz Wi-Fi. Choose the iRobot Roomba 115X Combo for a small home that wants mopping and hands-off bin emptying, and the iRobot Roomba 105X for the cheapest mapped vacuuming with no extras to maintain.

What the differences mean

Mopping

The iRobot Roomba 115X Combo wipes hard floors with a washable microfiber pad, while the iRobot Roomba 105X is vacuum-only: no mop, no water tank and no detergent support. If you want one machine to handle both jobs, only the combo does it.

Bin handling

The iRobot Roomba 115X Combo returns to an AutoEmpty dock that seals debris in a 2.5 L bag and can go about 90 days between changes, so you rarely touch the bin. The iRobot Roomba 105X has no self-emptying dock, so you empty its dustbin by hand after most runs.

Runtime

The iRobot Roomba 105X is rated for up to 120 minutes on a charge and the combo for about 100, so the smaller robot runs longer even though it cleans less per pass. In a small apartment neither will need a mid-clean top-up.

Size and weight

The iRobot Roomba 115X Combo is a compact robot at 245 mm across and about 2.16 kg, small enough to slip under low furniture. The iRobot Roomba 105X is a wider, taller chassis, so it needs more clearance and takes more floor space.

Which one to buy if

What owners say

Owners of the iRobot Roomba 105X describe a mapped vacuum that punches above its price. They single out strong everyday suction that pulls up more pet hair than they expected, LiDAR mapping that lets them send it to one room at a time, and an app that takes minutes to set up for schedules and no-go zones. The complaints are consistent too: a battery that needs a mid-clean recharge in larger homes, tangles on loose cords and door mats, and no mopping or self-emptying at all. Several mention it as a clear step up from an older bump-and-go robot, and as a good fit for a dedicated space like a litter box room.

Upgrading from the iRobot Roomba 105X?

Moving up from the iRobot Roomba 105X to the iRobot Roomba 115X Combo adds two jobs the smaller robot cannot do: a washable mop pad for hard floors and an AutoEmpty dock that seals debris in a bag for weeks. Navigation, LiDAR mapping, multi-room support and no-go zones are the same on both, and both stay on 2.4 GHz Wi-Fi with Alexa and Google Home. The one thing you give up is runtime, since the combo is rated lower per charge, but that rarely matters in the small spaces both are built for. If your iRobot Roomba 105X still handles the vacuuming and you never wanted a mop, there is little reason to move up; if you now want wet cleaning or a bin you stop thinking about, the combo is the step.
