Roomba 105 Vac Q312020 vs Q352020: Which dock fits your cleaning routine?
Choose Q312020 when you are comfortable emptying the robot bin yourself and prefer a charge-only dock. Choose Q352020 when reducing manual bin handling is worth adding bags and dock care. The AutoEmpty bundle is a documented convenience upgrade, not a proven cleaning or reliability upgrade.

The buying question
Does Q352020's AutoEmpty dock justify choosing that bundle over Q312020 for a vacuum-only cleaning routine?
Q312020 keeps the dock workflow simple and owner-managed, while Q352020 automatically attempts dust-bin emptying on each return but adds bags and dock care.
Quick verdict
Choose iRobot Roomba 105 Vac Robot Vacuum - Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multi-Surface Cleaning, Cleans in Neat Rows, Self-Charging if
- You are comfortable emptying the dust bin manually.
- You prefer the simpler charge-only dock workflow and no AutoEmpty bag supply.
- You want a vacuum-only Roomba 105 and do not need self-emptying.
Choose iRobot Roomba 105 Vac Robot Vacuum with AutoEmpty Dock - Self-Empties for 75 Days, Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multi-Surface Cleaning, Cleans in Neat Rows if
- You want the robot to attempt dust-bin emptying whenever it returns to its AutoEmpty dock.
- You run the robot often enough that fewer manual emptying steps matter.
- You accept bag replacement and monthly dock-filter/contact care.
When the recommendation changes
- If manual emptying is acceptable and the lower-complexity dock is the priority, Q312020 is the better feature fit.
- If reducing repeated bin handling matters more than dock consumables, Q352020 is the better feature fit.
- If the buyer needs a proven cleaning, noise, navigation-success or durability winner, the available evidence does not establish one.
The differences that matter
Dock Automation
iRobot Roomba 105 Vac Robot Vacuum - Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multi-Surface Cleaning, Cleans in Neat Rows, Self-Charging
The 105 Vac owner guide documents a Charging Dock with charging contacts and an IR window; the robot returns to the dock to recharge and resume, with no AutoEmpty cycle documented.[1]
iRobot Roomba 105 Vac Robot Vacuum with AutoEmpty Dock - Self-Empties for 75 Days, Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multi-Surface Cleaning, Cleans in Neat Rows
The Q352020 owner guide says the robot automatically attempts to empty its dust bin each time it returns to, or is placed on, the AutoEmpty dock. The exact Q352020 page lists one AutoEmpty Dock and advertises up to 75 days of hands-free emptying.[3, 2]
What this changes: Q352020 reduces the frequency of manual dust-bin handling through a documented dock routine; Q312020 keeps that step with the owner and avoids the AutoEmpty dock workflow.[1, 3, 2]
Maintenance
iRobot Roomba 105 Vac Robot Vacuum - Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multi-Surface Cleaning, Cleans in Neat Rows, Self-Charging
The charge-only guide calls for emptying the dust bin as needed, cleaning the filter weekly, cleaning brushes and caster wheel periodically, and cleaning charging contacts and sensors.[1, 4]
iRobot Roomba 105 Vac Robot Vacuum with AutoEmpty Dock - Self-Empties for 75 Days, Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multi-Surface Cleaning, Cleans in Neat Rows
Q352020 keeps the same robot/filter/brush/contact care and adds AutoEmpty bag replacement when full, plus monthly dock-filter, charging-contact and IR-window care.[3, 4]
What this changes: AutoEmpty changes the most frequent emptying step into a bag workflow but adds dock-specific upkeep; it does not make ownership maintenance-free.[1, 3, 4]
Vacuum Only Scope
iRobot Roomba 105 Vac Robot Vacuum - Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multi-Surface Cleaning, Cleans in Neat Rows, Self-Charging
Q312020 is the Roomba 105 Vac catalog configuration; the official 105 guide identifies water tanks and mop-pad parts as Combo-only, so this configuration is not a mopping bundle.[1]
iRobot Roomba 105 Vac Robot Vacuum with AutoEmpty Dock - Self-Empties for 75 Days, Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multi-Surface Cleaning, Cleans in Neat Rows
The exact Q352020 manufacturer page names the product Roomba 105 Vac Robot + AutoEmpty Dock, and the AutoEmpty guide marks water-tank and mop-pad parts as Combo-only.[2, 3]
What this changes: Both products answer a vacuum-only buyer's question; a shopper who wants mopping should compare a separate Roomba Combo configuration.[1, 2, 3]
Real World Cleaning Performance
iRobot Roomba 105 Vac Robot Vacuum - Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multi-Surface Cleaning, Cleans in Neat Rows, Self-Charging
No applicable independent bilateral test was found for the Q312020 charge-only bundle in this research pass.[1]
iRobot Roomba 105 Vac Robot Vacuum with AutoEmpty Dock - Self-Empties for 75 Days, Easy to use, Intense Power-Lifting Suction, LiDAR Navigation, Multi-Surface Cleaning, Cleans in Neat Rows
Vacuum Wars reports controlled 105 Vac measurements for the self-emptying configuration, but its review does not test Q312020 and does not provide a Q312020-versus-Q352020 head-to-head result.[5]
What this changes: The available evidence can support a dock-workflow choice, but it cannot establish that either bundle cleans better, navigates more reliably, runs quieter or lasts longer than the other.[1, 5]

Need a vacuum-only Roomba 105 rather than a mopping bundle
No clear winner
Both exact product records are Roomba 105 Vac configurations; the official guides identify water tanks and mop pads as Combo-only parts.
What the evidence cannot decide
- Buy for proven cleaning or long-term reliability superiority: The independent test covers the AutoEmpty configuration only, and no bilateral E2/E3 evidence supports a winner for this exact pair.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
The Q352020 premium should be treated as payment for the documented AutoEmpty workflow and its reduced manual bin handling, while Q312020 preserves the simpler charge-only routine. It is not evidence of better cleaning.
Recent price observations for both products cover only a short window. Use the current offer display, but do not make a historical-low or definite Buy Now/Wait recommendation.
Is the upgrade worth it?
Worth considering if
- Households that run the vacuum frequently and dislike handling a full robot bin.
- Buyers with room for the AutoEmpty dock and a willingness to keep replacement bags available.
- Shoppers paying for convenience rather than an assumed cleaning-performance gain.
Skip the upgrade if
- Manual emptying is acceptable or the robot will run only occasionally.
- You want the fewest dock consumables and the simplest care routine.
- You expect AutoEmpty to remove filter, brush, bin or dock maintenance.
Limitations
- The exact Q312020 product page was not available in the current public iRobot site crawl; the catalog record identifies its product identity and charge-only bundle, while the official 105 Vac owner guide documents the charge-only dock configuration.
- Vacuum Wars provides controlled 105 Vac measurements for the self-emptying configuration only; no bilateral Q312020-versus-Q352020 test supports a performance or reliability winner.
- The price history is short and supports current dynamic display only, not a typical price, historical low or Buy Now/Wait call.
- No community discussion was opened or used as public evidence. Owner experience can be researched separately if needed.
- This is a source-backed draft; no hands-on testing occurred.
Questions shoppers ask
What is the main difference between Q312020 and Q352020?
Q312020 uses the charge-only dock and leaves bin emptying to the owner. Q352020 adds an AutoEmpty dock that automatically attempts to empty the bin whenever the robot returns to or is placed on the dock.
Does AutoEmpty eliminate routine maintenance?
No. The robot still needs regular filter, brush, bin, sensor and contact care. The AutoEmpty configuration also requires replacing full bags and cleaning its dock filter and contacts on the documented schedule.
Do these Roomba 105 Vac bundles mop?
No. The products are the vacuum-only Q312020 and Q352020 configurations. The official guides mark the water tank and mop-pad parts as Combo-only, so choose a separate Roomba Combo listing if mopping is required.
Is Q352020 proven to clean better than Q312020?
This comparison cannot establish that. The independent test checked the 105 Vac self-emptying configuration but did not provide a bilateral test against Q312020, so the upgrade case is dock convenience rather than proven cleaning superiority.
