iRobot Roomba 105 Combo vs Lefant M2S Pro
Which one to buy
Ten dollars more gets you a self-empty dock with the Lefant M2S Pro, and that's hard to ignore. Both are LiDAR vacuum-and-mop robots that map more than one floor and steer around carpet when the mop is on. The Lefant adds a bagless station rated for 90 days hands-free, PSD obstacle sensors that work in the dark, a 240-minute runtime rating and a 10,000 Pa suction figure. iRobot publishes no suction, runtime or bin figures for the Roomba 105 Combo, has no dock that empties it at this price, and has no obstacle avoidance.
What the Roomba has is a track record and support. Owners like its tidy row-by-row coverage, are impressed by its dog-hair pickup, and describe an app simple enough to hand to elderly parents. They value iRobot's US parts and warranty network. They're also frank about the downsides: the mop pad just drags damp and won't touch dried spills, it has to be clipped on and off by hand, carpet avoidance is good but not perfect, and cables and socks get eaten. Some report docking trouble, and many weigh iRobot's shaky finances against long-term app support.
The Lefant's 150 ml bin is small, but the dock empties it. Its mop also avoids carpet rather than lifting, the same approach as the Roomba.
For most buyers the M2S Pro is more robot for the money. The Roomba makes sense if you value a simple app and established US support over a dock and obstacle sensing.
iRobot Roomba 105 Combo
Suits you if you want the simplest app and iRobot's US parts and warranty network, and you don't mind emptying the bin and tidying the floor first.
Lefant M2S Pro
Makes sense if you want a self-empty dock, obstacle sensing and a 240-minute rating for $10 more, and you're comfortable with a less established brand.

- ✗iRobot publishes no runtime, suction, or bin specs whatsoever
- ✗No self-empty dock at this price tier
- ✗iRobot's ongoing financial troubles cloud long-term support

- ✓Long 240-minute runtime off a 5200mAh battery
- ✓Quiet mode rated under 60 dB

- ✗Small 150ml dustbin between empties (mitigated by the self-empty station)

iRobot Roomba 105 Combo vs Lefant M2S Pro: common questions
Is the Lefant M2S Pro's self-empty dock worth $10 over the Roomba 105 Combo?▾
For nearly everyone, yes. The Lefant's bagless station is rated for 90 days hands-free, while the Roomba 105 Combo at this price has a charging dock only and owners say its bin is small, so you empty it by hand.
Which one avoids cables and socks?▾
The Lefant has PSD obstacle avoidance with nine sensors that work in the dark. The Roomba 105 Combo has none, and owners say cables, socks and pet toys get eaten unless you tidy first.
Do either of these lift the mop over rugs?▾
Neither lifts its mop. Both steer around carpet while the mop is attached, and Roomba owners say that works most of the time but leaves the occasional damp rug corner. Lefant boosts suction to maximum when you remove the mop holder.
