iRobot Roomba 105 Combo review

I haven't used this robot. I'm working from iRobot's own product page and the one published outlet test, a Reviews.org review from Australia dated May 20, 2025. The opinions are mine.

There's a catch with that test, so I'll put it up front. Reviews.org reviewed the Australian listing of the 105 Combo, and its review doesn't show whether that unit matches the US bundle with the AutoEmpty dock. It does mention an auto-empty dock. Same box? Maybe. That's why there's no score here yet.

The price

As of November 13, 2026, iRobot's price for the 105 Combo with the AutoEmpty dock is $299.99Not verifiedNot verified.

What iRobot says it is

This is the entry combo in the Roomba range. It has LiDAR navigation, a microfiber mop pad and a dock that empties the bin. iRobot says ClearView LiDAR "quickly maps your home, avoids obstacles and cleans in neat rows, even in the dark." There's no obstacle-recognition AI at this level of the line.

The robot is 4.09 in tall. Measure the gap under your sofa before you order. It weighs 6.45 lb and runs on a 3000 mAh LFP battery.

Two numbers are missing, and they bother me. iRobot prints no run time. It also gives no suction figure in pascals, just "70X more power-lifting suction" than the Roomba 600 series. That's a comparison with a robot line most people haven't owned in years, so it tells me very little.

How it vacuums, per Reviews.org

Reasonably well. Reviews.org measured about 80-90% particle clearance when vacuuming. It also says the robot picked up around 80% of the debris next to walls, and edges are where round robots usually struggle.

That's the part of this product I'd pay for.

How it mops

Badly. Reviews.org measured 60% clearance on mopping, and it says wet and sticky spills were mostly smeared around. A pad dragged behind a robot is a light wipe for dusty hard floors. Don't expect it to handle the juice under the kitchen table.

If mopping is why you're shopping, this is the wrong Roomba.

The dock

iRobot claims the dock auto-empties for up to 75 days. Reviews.org found that the dock didn't fully empty the bin, so the bin often needed cleaning by hand. A self-emptying dock exists so you don't touch the bin. If it can't manage that, you're paying for a large plastic trash can.

To be fair, this is one test, and it may not have used the US bundle. I'd want a second outlet to say the same thing before I write the dock off.

Reviews.org scored the robot 3.75 out of 5 overall and 3.27 for performance.

Against the Roomba 105 Vac

The 105 Vac ($279.99Not verifiedNot verified) is the vacuum-only sibling at the bottom of the line. Since the mop cleared only 60% in Reviews.org's test, I'd look hard at that model. Check whether its bundle includes the dock you want. If the gap between the two prices is small, the Combo's mop costs you little. If it's large, I'd keep the money and use a real mop once a week.

Against the Roomba Plus 415 Combo

The Plus 415 Combo ($599.99£449€499) is the next combo up. Its dock washes the mop as well as emptying the bin. That's one chore the 105 Combo leaves to you.

Who I'd point at it

Someone with mostly hard floors and pets that shed, who wants mapping and a dock without a big bill. I'd also want them to be fine with emptying the bin now and then anyway.

I'd skip it if you need a robot that reliably mops, or one that can steer around cables and socks on the floor.

What I'm waiting for

A US test of this exact bundle, a run time from iRobot, and a launch date. iRobot's page prints none of the last two.
