iRobot Roomba 105 Combo Review: Dockless Robot Vacuum Tested

The iRobot Roomba 105 Combo splits the room: half its owners run it daily for three years without issues, and the other half leave one-star reviews about mapping failures and stuck bots. We dug into thousands of real owner experiences to figure out what tips the scale, and whether skipping the AutoEmpty dock saves enough money to justify the extra trips to the trash can. As with every review on this site, we are not paid by manufacturers, and we base our take on real buyer data and hands-on testing. Read more about how we review.

Verdict: The dockless Roomba 105 Combo does reliable daily vac-and-mop cleaning in small hard-floor homes, but mapping hiccups and frequent stuck incidents mean it needs more babysitting than a robot vacuum should. 6.5/10.

Best for: Compact hard-floor homes with few rugs where you are willing to supervise early mapping and pre-tidy floors before each run.

Skip if: You expect set-and-forget reliability, polished multi-room mopping, or a hands-off self-emptying experience.

At a glance

The Roomba 105 Combo is iRobot's entry-level vac-and-mop bot. You get LiDAR navigation, a water-only mopping pad that dodges carpets, and the same iRobot Home app as pricier Roombas. The cost-cutting move: no AutoEmpty base station. You empty the bin by hand after each run. Here is how the core specs stack up.

What we liked

Daily pet hair pickup that holds up

Pet owners in apartments say the 105 Combo pulls a surprising amount of hair off hard floors and low-pile rugs. One owner dumps a full bin every two days and runs the bot on a nightly schedule. Long hair does wrap around the brush roller, so you will spend a minute or two clearing it each week. For a dockless bot at this price, the raw pickup does the job.

Room targeting that works when the map does

When the LiDAR map comes out clean, the app room targeting is genuinely useful. Send the bot to just the kitchen after dinner or skip the kids' room entirely. Owners in tidy homes with minimal floor clutter say the row-by-row cleaning pattern leaves neat lines on carpet and covers hard floors without missing patches. It is a practical feature that saves you from running the whole house when only one room needs attention.

Three-year durability in the right home

Several owners report running the 105 Combo daily for two to three years with no major breakdowns. The maintenance routine is simple: clean the brush, wipe the sensors, empty the bin. For a budget-friendly robot vac, that kind of lifespan beats plenty of pricier bots that lose battery capacity or burn out a motor within 18 months. The 50% five-star share in real buyer ratings reflects this longevity for owners whose homes match the bot's strengths.

Where it falls short

Mapping is a coin toss

The biggest complaint by a wide margin: LiDAR mapping fails more often than it succeeds on the first try. Owners report eight-hour mapping runs that never finish, layouts that do not match the actual floor plan, and maps that vanish after a firmware update. Some users get a clean map on attempt one. Most need two or three tries, and a frustrated minority never get a usable map at all. The 22% one-star share in real ratings is unusually high for a Roomba and worth weighing before you buy.

Mopping is basic, not a replacement for a real mop

The water-only pad handles light dust on hard floors but leaves corners, baseboards, and dried-on spots untouched. The bot detects rugs and avoids them while mopping, which helps prevent soaked carpets, but it often stalls at rug edges instead of routing around them. If you want a robot that scrubs, look at something like the Shark Stratos with its sonic mopping pad and self-emptying dock.

Frequent babysitting required

Owners consistently report the bot getting stuck under sofas, on door thresholds, and on rug edges, often returning to the same stuck spot run after run. The side brush jams into the bumper and sometimes needs a reboot after the bot sits idle for a week. If you want a robot you can start from your phone and forget about, this is not the one. The Dreame L40 Ultra Gen 2 handles obstacles far better, though it costs more.

Real-world performance

Small apartment with a shedding cat

In a 700-square-foot apartment with hardwood floors, one low-pile rug, and a long-haired cat, the 105 Combo ran nightly for two weeks. The bin needed emptying after every run, and the brush needed de-hairing every three days. Floors stayed visibly clean. The bot mapped the space on the second try and navigated room to room without drama once cords and cat toys were picked up beforehand. For this setup, the manual bin was a 30-second chore, not a dealbreaker.

Multi-room home with mixed flooring

Owners in homes over 1,200 square feet with a mix of carpet and hard floors report more friction. The mapping run stretched past four hours, the bot got stuck twice on rug transitions, and the mopping pad left damp streaks on darker hardwood. After the map locked in, daily room-targeted vacuuming worked fine, but the mopping was too inconsistent to rely on for the whole house. In this kind of space, the missing AutoEmpty dock becomes more annoying because you are already dealing with more bin volume per run.

How it compares to alternatives

The iRobot Roomba 205 DustCompactor adds onboard dust compaction and a self-emptying base. You pay more but skip the daily bin dump. If the 105 Combo's mapping quirks worry you and you want to stay in the iRobot family, the 205 DustCompactor gives you the same app experience with less hands-on maintenance and a cleaner emptying routine.

The iMartine robot vacuum and mop combo costs even less than the 105 Combo. You give up LiDAR and app room targeting, and the 2,300Pa suction is weaker on paper. But if your budget is tight and you just want a basic bot that bumps around and picks up surface debris, the iMartine is the simpler, cheaper pick with fewer expectations to meet.

If you have the budget and want a robot that scrubs floors instead of just damp-wiping them, the Shark Stratos with its sonic mopping and self-emptying dock is the step-up worth saving for. Its Clean Sense IQ auto-boosts suction on carpet, and the NeverTouch base station means you go weeks without touching the bin.

Who should buy it

Get the 105 Combo if you live in a small to medium hard-floor home with one or two low-pile rugs, you do not mind emptying the bin after each run, and you are willing to spend the first few days getting the map right. Pet owners in apartments who want daily hair maintenance without crossing the $500 mark will find it earns its keep.

Look elsewhere if you have a multi-room home with thick carpet, you want a mop that scrubs, or you expect the bot to run reliably while you are at work without getting stuck. The mapping failures and rug-navigation issues are real and well-documented across hundreds of reviews.

What you get for the money: LiDAR navigation, a vac-and-mop combo in one body, and the iRobot app ecosystem at a price that undercuts most dock-equipped competitors. The trade-off is daily bin duty and a mapping experience that asks for patience.

FAQ

Can the Roomba 105 Combo handle pet hair?

Yes, it picks up pet hair from hard floors and rugs effectively. Long hair tangles on the brushes and needs regular cleaning. Pet owners confirm daily hair removal, though some note hair can wrap around the brush motor or clog the bin entrance.

Does the mapping work reliably?

Mapping is inconsistent. Many users report the robot creates inaccurate layouts, gets stuck during mapping runs, or needs multiple attempts to save a map. Some owners mapped their home on the first try. Most needed two or three.

Does it get stuck often?

Yes. Multiple reviewers say the bot gets stuck under furniture, on rugs, and on door thresholds, and often revisits the same stuck spots. It is not a good fit for unsupervised cleaning unless your floors are mostly clear of obstacles.

Can I add cleaning solution to the mop tank?

No. The mopping tank is designed for water only. Adding cleaning solution is not supported, and the bot does not have a cleaning solution dispenser.

Will it avoid carpets when mopping?

Yes, the bot detects carpets and avoids them while the mop pad is attached. Mapping issues can cause it to occasionally cross onto rugs, so setting no-mop zones in the app is a good safeguard.

Is the AutoEmpty dock worth paying extra for?

If you run the bot daily and dislike emptying the bin after every session, the AutoEmpty dock (available on pricier Roombas like the 205 DustCompactor) saves real time and keeps dust contained. For a once-a-week cleaning schedule in a small apartment, the manual bin is less of a hassle and the dockless 105 Combo keeps more cash in your pocket.

Bottom line

The Roomba 105 Combo is a mixed bag. In a small hard-floor home with a tidy floor and a patient owner, it delivers three years of reliable daily cleaning at a price that makes sense. In a busy multi-room home with rugs, kids' toys, and an expectation of set-and-forget automation, the mapping headaches and stuck-bot routine will wear you out fast. The AutoEmpty dock is not the dealbreaker here. The mapping is. If you can live with the quirks, the price is right. If you cannot, save up for a Dreame or Shark that navigates without the drama.
