01 Classification
What each one does on its own.
The Autonomy Ladder is the same five rungs for every robot on the site. A rung describes the conditions a robot handles without you, not how good it is.
V
Generalized
Any task, any setting
IV
Environmental
Handles new obstacles without help
III
Conditional
Finishes familiar jobs on its own

02 Assessment
Where they actually differ.
The Robovations Score is nine inputs across three pillars, each weighted as shown and each scored so that more is better. A robot can lead on one and trail on another, which is the point of showing them apart. Cost of ownership and data handling are reported on each robot's own page and are never averaged into the score.

04 Ownership
What the numbers leave out.
The trade-off
What each design gives up to be good at what it is good at.
Ecovacs Deebot N79S
You are buying a decade-old bump-and-go path at what mapped budget robots now cost, with none of the mapping.
Random-path coverage leaves crumbs at the edges, so owners run auto clean and then a separate edge clean to finish the job.
No obstacle sensing: cords and loose items get gobbled rather than avoided, so floors need clearing before every run.
iRobot Roomba 105 Combo
LiDAR and auto-empty at an entry price, with no independent test of the Combo yet.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Ecovacs Deebot N79S
- Any buyer seeking mapped, systematic navigation
- The N79S has no mapping and no adaptive path planning; it cleans by bump-and-go, so coverage is a function of runtime rather than of a plan. App control and scheduling do exist, in the Ecovacs app and on the bundled remote, but neither makes the coverage systematic.
- Homes with obstacles or complex layouts
- Random-path navigation handles simple rooms adequately but fails in cluttered homes, multi-room layouts, or narrow passages where systematic coverage would be more efficient.
- Buyers needing current support
- Ecovacs discontinued this model years ago. No warranty coverage, spare parts are difficult to source, and manufacturer support is inactive.
iRobot Roomba 105 Combo
- Buyers who want independent test results first
- No hands-on review of the 105 Combo was found; the tested Roomba 105 models are the vacuum-only 105 Vac.
- Rooms where carpets need mopping nearby
- iRobot describes carpet avoidance while mopping, so rugs are skipped rather than vacuumed with the pad lifted.
- Buyers wary of the maker's long-term future
- iRobot filed for Chapter 11 in Dec 2025 with a planned acquisition by Picea Robotics, per HotHardware.
- Owners wanting a dock that washes the mop
- The optional AutoEmpty dock empties debris only; TechRadar reserves mop washing for the Plus 405 and 505 Combo.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Ecovacs Deebot N79S
- Weekly: Empty dust bin after each session.
- Monthly: Rinse filter with water; air-dry fully before reinstalling.
- Every 3-6 months: Clean brush bristles and remove wrapped hair from side brush.
- Annually: Replace brush bristles if worn; OEM replacements cost $15-25.
iRobot Roomba 105 Combo
- As needed: Replace the AutoEmpty dock bag, which the retail listing says holds up to 75 days of debris.
- After every use: Refill the water tank and rinse the mop pad after mopping runs.
- As needed: Empty the onboard bin by hand on the version sold without the AutoEmpty dock.
- As needed: Clean the brushes and filter, and replace them when worn.
- As needed: Keep the iRobot app updated, since iRobot said app functionality would continue through its restructuring.
05 Evidence
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
