Roomba 104 Combo AutoEmpty vs 105 Combo Charge-Only Dock
The Roomba 104 Combo package is the convenience choice because its exact Y351020 bundle includes an AutoEmpty Dock. The Roomba 105 Combo Y314020 package is the simpler charge-only configuration, so the choice turns on dock automation and bundle preference rather than an assumed robot-core performance gap.

The differences that matter
dock automation
iRobot Roomba 104 2in1 Vacuum & Mop Robot - Self-Empties for 75 Days, Intense Power-Lifting Suction, Vacuums All Floors, Ideal for Pet Hair, LiDAR Smart Navigation Mapping, Mops Hard Floors: The exact Y351020 box includes an AutoEmpty Dock; iRobot documents automatic emptying for up to 75 days and a bag designed to trap 99% of allergens as small as 0.7 microns.
iRobot Roomba 105 Combo Robot Vacuum & Mop - Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multiple Cleaning Modes, Avoids Mopping Carpets, Self-Charging: The exact Y314020 box includes a Charge-Only Dock, not an AutoEmpty Dock; the official SKU page does not list automatic dirt disposal for this package.
Product A reduces routine dust-bin handling through the included AutoEmpty Dock, while product B leaves emptying as a manual owner task.

The packages are not interchangeable identities: verify the item number and dock type before using a listing's title, accessories, or price in this comparison.
upgrade premium
iRobot Roomba 104 2in1 Vacuum & Mop Robot - Self-Empties for 75 Days, Intense Power-Lifting Suction, Vacuums All Floors, Ideal for Pet Hair, LiDAR Smart Navigation Mapping, Mops Hard Floors: The Y351020 package adds the AutoEmpty Dock and its documented bag-based disposal workflow to the Roomba 104 Combo purchase.
iRobot Roomba 105 Combo Robot Vacuum & Mop - Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multiple Cleaning Modes, Avoids Mopping Carpets, Self-Charging: The Y314020 package is the charge-only Roomba 105 Combo configuration; its official packout does not include an AutoEmpty Dock.
The AutoEmpty premium is easier to justify for owners who prioritize less frequent bin handling; it is less compelling when a charge-only dock and manual emptying already fit the household routine.
Choose for your routine
Minimize routine dust-bin handling
The Y351020 package includes the AutoEmpty Dock, while Y314020 is explicitly charge-only.
Keep the dock configuration simple
The Y314020 package is built around a Charge-Only Dock and avoids adding the AutoEmpty dock workflow.
Choose based on the household's value of dock automation
Both are Combo robot vacuum-and-mop packages, but the exact dock and associated maintenance routine differ.
Value and trade-offs
Treat any observed premium for product A as payment for the included AutoEmpty Dock workflow and its reduced routine handling, not as proof of superior robot-core cleaning.
Recheck the live offer and exact packout at review time; the short tracked price window supports context but not a timing recommendation.
When to upgrade
- Owners who want less frequent manual dust-bin emptying.
- Homes where the AutoEmpty dock workflow is more valuable than the simpler charge-only setup.
Skip the upgrade if
- A charge-only dock meets the household's routine.
- The listing cannot verify the Y351020 model and included AutoEmpty Dock.
Limitations
- This is an official-specification comparison; no hands-on test was performed.
- The official pages establish package identity and dock features, but they do not establish a bilateral robot-core cleaning or navigation performance winner.
- Price observations are from a short tracked window and should be refreshed before any purchase decision.
- Family-level support guidance about mopping is not used to override the exact Y351020 and Y314020 packouts.
Does the Roomba 104 Combo package include an AutoEmpty Dock?
Yes. The exact Y351020 official page identifies the package as Roomba 104 Combo Robot + AutoEmpty Dock and lists the AutoEmpty Dock in the box contents.
Does the Roomba 105 Combo Y314020 package include automatic dirt disposal?
The exact Y314020 official box contents list a Charge-Only Dock and do not list an AutoEmpty Dock, so treat this SKU as the charge-only configuration.
Is the AutoEmpty bundle automatically worth the premium?
Not for every household. It is most defensible when reducing routine dust-bin handling matters; otherwise the Y314020 charge-only package may better fit a simpler routine.
Methodology and sources
