Choose a robot vacuum if your home is mostly carpet or rugs and your main need is picking up dry debris. Choose a robot vacuum-and-mop combo if you want regular damp wiping on hard floors. If you have both hard floors and rugs, check how the specific model handles carpet before buying: some require you to remove rugs or set room exclusions, while others lift or retract the mop pad. A combo also means extra water and pad care.
What is the difference between a robot vacuum and a robot mop?
A robot vacuum’s main job is dry pickup. A robot mop uses a damp pad or another wet-cleaning system on hard floors. A robot vacuum with mop—also called a combo or 2-in-1—combines those jobs, but models differ in how they switch between them and protect carpets.
For example, iRobot says its Roomba Combo i5 vacuums with a combo bin installed and can use a separate dry-vacuum bin instead. That is a model-specific arrangement, not a standard shared by every combo.
Which type fits your floors?
Mostly carpet or rugs
Start with a vacuum-only robot if dry debris is the main problem and carpet dominates your home. It focuses on vacuuming without adding a water tank or mop pads to maintain. Wet mopping is generally not a substitute for carpet cleaning: eufy Australia cautions that excess moisture can contribute to staining, shrinkage, or prolonged dampness on some carpets, particularly wool or thick-pile varieties. Follow the care instructions for both your carpet and any robot you consider.

Mostly sealed hard floors
A combo may suit you if you want regular damp wiping as well as dry pickup. iRobot describes the Combo i5 as able to vacuum hard floors and carpet, with optional mopping for hard floors; its microfiber pad is intended for footprints, dirt, and dust. That product description does not guarantee removal of every dried spill or suitability for every floor finish. Check your flooring maker’s care guidance and the robot’s approved water or cleaning-solution instructions.
A mix of hard floors and rugs
Do not assume the word “combo” means the robot will keep a wet pad off every rug. Check the exact model’s carpet detection, pad-lifting behavior, app controls, and instructions for no-mop areas.

- The Roomba Combo i5 instructions say to roll up carpets or restrict cleaning to rooms without rugs when mopping with its combo bin installed.
- In a September 27, 2022 company announcement, iRobot described the j7+ as having a retractable pad that lifted to the top when it encountered carpet. This is a historical description of that model, not a guarantee about current combos generally.
Use the current manual and product details for the model you are considering; carpet safeguards differ.
What work does mopping add?
A combo’s wet-cleaning system adds upkeep beyond the usual dustbin and brush care. ECOVACS identifies water refills and pad sanitizing as tasks to account for. A model’s dock may automate some maintenance, but dock features differ and may bring extra consumables or complexity. Check what the specific model automates, what you must do yourself, and which replacement pads fit.

Water settings matter, too. ECOVACS advises adjusting them for moisture-sensitive floors. Follow the floor manufacturer’s care instructions and the robot maker’s guidance on water and cleaning solutions.
How to compare models before buying
- Map your floors. Note how much of your home is carpet, rugs, or hard flooring, and whether rugs sit in the robot’s regular route.
- Identify the regular job. If you mainly want dry debris picked up, prioritize vacuuming. If hard floors need routine damp wiping, consider a combo.
- Verify the carpet plan. Look for pad lifting or retraction, carpet detection, app-based room exclusions, and any instruction to remove rugs. Confirm how the model behaves while mopping—not just while vacuuming.
- Account for care. Check how often the water tank and pads need attention, whether the dock handles any of those tasks, and the cost and compatibility of replacement parts.
- Compare the exact models. Evaluate model-specific features and costs rather than assuming that all vacuum-only robots or all combos perform alike.
What the available product guidance can—and cannot—tell you
Manufacturer guidance helps explain intended uses and operating requirements, but it is not independent comparative testing. ECOVACS presents vacuum-only models as a simpler fit for carpeted spaces and combos as useful for dry and wet cleaning across mixed floors. iRobot’s product instructions show why the carpet plan still needs checking model by model.

In its September 27, 2022 announcement, iRobot’s then chief product officer Keith Hartsfield said: “Until today, many 2-in-1 robot vacuums and mops delivered a poor user experience either because they required separate, time-consuming cleaning jobs or created more mess by not fully lifting the mopping pad high enough to avoid carpet and rugs.” That is a company executive’s promotional statement, not an independent test result. These sources do not establish that every robot mop cleans better, or that every combo vacuums worse, than a vacuum-only robot.
