iRobot Roomba 105 Combo Review: The $299 Robot That Vacuums, Mops, and Takes Out Its Own Trash

Robot vacuums at $299 usually make you pick your compromise: vacuuming or mopping, smarts or suction — or you pay a lot more. The Roomba 105 Combo refuses the tradeoff. It vacuums and mops in a single run, and when it's done, it empties itself into a dock that holds up to 75 days of debris.

That last part is the whole ballgame. The dustbin is the thing every robot vacuum owner hates touching — the daily ritual of popping it out and shaking pet hair into the trash. The 105 Combo deletes that chore for two and a half months at a time. When we ranked the best-selling robot vacuums of 2026, no other pick under $300 came close to this much automation.

Who it's for

• Pet owners — self-emptying means no daily dustbin full of hair
• Busy households that want floors handled, not another gadget to babysit
• Mixed hard-floor and carpet homes — it vacuums rugs and mops hard floors in one pass
• First-time robot buyers who want the full experience without the $600 flagship price

Key specs

• Vacuums and mops in a single cleaning run

• Systematic row-by-row navigation with home mapping
• App control: schedules, room-by-room cleaning, keep-out zones

• Carpet detection keeps the mop pad off rugs
• Washable, reusable mop pad

Why it actually wins

Do the value math. A vacuum-mop combo with a self-emptying dock usually starts around $450–$500. The 105 Combo delivers all three for $299. In our guide, the eufy and Roborock contenders either skipped mopping, skipped the self-emptying dock, or cost meaningfully more once you added the dock.

The mopping is real, with limits. It lays down water and wipes hard floors as it vacuums — great for dust, footprints, and everyday grime. It will not scrub dried spaghetti sauce off tile. Think of it as a robot that maintains clean floors, not one that deep-cleans dirty ones. Set expectations there and you'll be happy.

The app does the thinking. Schedules, room-specific runs, keep-out zones — the iRobot Home app covers the essentials, and mapping means it cleans in efficient rows instead of the old bump-and-pray pattern. Voice control works for the lazy "Alexa, clean the kitchen" moments.

Pet hair is its favorite food. The self-emptying dock is the killer feature for pet homes: instead of emptying a hair-packed bin every day, you forget about it for weeks. The 75-day claim assumes average use — with three shedding dogs, plan on less, but still far less often than a manual bin.
