The iRobot Roomba 115X Combo is a robot vacuum and mop in one, paired with a dock that empties the robot for you. It's aimed at small to medium homes that want floors cleaned daily without anyone touching a vacuum.
Here's what it does, where its limits are, and one thing about the company every buyer should know.
Quick Verdict
Best for: small to medium homes, pet owners, and allergy sufferers who want hands-off daily vacuuming and light mopping.
Skip it if: you have a large home with lots of square footage per floor, or you need deep scrubbing of dried-on stains.

The 115X Combo vacuums with 15,000 Pa of suction to pick up crumbs and fine dust while its pad mops everyday buildup in the same run. It covers up to 900 square feet per charge, which suits apartments and small to medium homes.
It also avoids mopping carpet, so you don't end up with damp rugs.
Self-Emptying for Up to 3 Months
After each clean, the robot empties into the AutoEmpty dock. Its 2.5-liter AllergenLock bag traps 99% of pollen and mold and seals itself when you remove it, so there's no dust cloud when you change it. iRobot says one bag lasts up to about 90 days.

LiDAR Navigation
LiDAR uses a laser to map your home, so the robot cleans in efficient, organized lines instead of bumping around at random. Combined with multiple cleaning modes, it gives you more control over how and where it cleans. If hands-off floors are the goal, this is the kind of setup that delivers.
Know Before You Buy
- Coverage: up to 900 square feet per charge, so bigger homes may need more than one run.
- Light mopping only: the pad handles everyday buildup, not dried-on spills or heavy scrubbing.
- You wash the mop pad yourself: the dock empties dust only. The washable pad has to be taken off and washed by hand.
- Wi-Fi: the app needs a 2.4 GHz Wi-Fi network.
- Ongoing cost: dock bags and mop pads are replacement items you'll buy over time.
- About the company: iRobot went through Chapter 11 bankruptcy in December 2025 and was acquired by its manufacturer, Picea Robotics, in January 2026. The company has said the app, warranties, and product support continue as normal.

Should You Buy the Roomba 115X Combo?
For small to medium homes that want clean floors every day with almost no effort, the Roomba 115X Combo is a strong all-in-one choice. The sealed, self-emptying dock is especially good news for anyone with allergies.
If you have a large home or want heavy-duty mopping, look at a model with a bigger battery range or a dedicated mopping system.
