The main trade-off
The 505 adds dock automation, dual spinning mop pads and obstacle recognition, but requires a hard-floor AutoWash location and still needs routine care; the 105 uses a charge-only dock and leaves emptying and pad care to the owner.
Quick verdict
The 505 is the stronger feature fit for shoppers who want dock-assisted emptying and mop-pad care; the 105 is the simpler choice when a charge-only dock and owner-managed maintenance are acceptable. Both support LiDAR mapping, SmartScrub and carpet avoidance while mopping, so the documented dock and care differences—not a proven cleaning-performance gap—should drive the decision.
Choose Roomba 105 Combo if
- You prefer a simpler robot-and-charge-dock setup.
- You are comfortable emptying the bin, cleaning the filter and handling the microfiber pad yourself.
- You do not want the AutoWash dock's added tanks, basin and clearance requirements.
Choose Roomba Plus 505 Combo if
- You want the dock to auto-empty debris and wash and heat-dry mop pads between runs.
- You regularly mop and the reduction in routine pad handling matters more than the AutoWash dock's added care tasks.
- You want the 505's documented dual spinning pads, pad auto-lift and PrecisionVision obstacle recognition.
When the recommendation changes
- If routine dock visits are the main annoyance, the 505's documented AutoWash functions become more valuable.
- If a simple charge-only routine matters more than automated pad care, the 105 remains the narrower fit.
- If you need proven real-world cleaning, reliability or mopping speed superiority, this comparison cannot establish a winner from official specifications alone.
The differences that matter
| Decision point | Roomba 105 Combo | Roomba Plus 505 Combo |
|---|---|---|
| Dock Automation | The exact Y314020 box contents list a Charge-Only Dock; bin emptying and mop-pad handling remain owner tasks.[1, 4] | The N185020 includes an AutoWash dock that auto-empties debris, refreshes and washes pads, heat-dries pads and runs self-cleaning cycles; iRobot describes up to 75 days of auto-emptying and four weeks of mopping/pad washing based on one mopping run per week.[2] |
What this changes: This is the clearest reason to choose the 505: it moves recurring emptying and much of pad washing/drying into the dock. It does not make the robot maintenance-free.[1, 2] Best fit: Roomba Plus 505 Combo | ||
| Mopping System | The 105 uses a single microfiber mop pad with a micro-pump and selectable liquid amount; its published modes include mop-only and combo cleaning, and it avoids mopping carpets.[1, 3] | The 505 uses DualClean spinning pads with PerfectEdge, SmartScrub and documented 200 RPM pad rotation; its pads auto-lift when carpet is sensed and the robot supports vacuum-only, mop-only, combo and vacuum-then-mop modes.[2] |
What this changes: The 505 offers more documented mopping hardware and a more automated carpet transition. That supports feature-fit advice for frequent mopping, but neither official page supplies a comparable independent test proving better stain removal or faster coverage.[1, 2] The better fit depends on your priorities | ||
| Navigation And Obstacle Handling | The 105 uses ClearView LiDAR for mapping and row navigation, with app scheduling, room targeting and keep-out zones.[1, 3] | The 505 combines ClearView Pro LiDAR with PrecisionVision AI for recognizing and avoiding cords, shoes and pet waste; iRobot says it can create up to five maps.[2, 3] |
What this changes: The 505 is the feature fit for shoppers who specifically want the additional published obstacle-recognition layer. The sources do not establish a comparative rate of avoidance, fewer rescues or better cleaning coverage.[1, 2, 3] The better fit depends on your priorities | ||
| Dock Placement And Maintenance | The exact Y314020 bundle ships with a charge-only dock. iRobot's 105 care guidance says to remove and empty the bin, clean it regularly without soaking it, remove debris from the filter, wipe charging contacts, clean the brush as needed and replace the filter every 3-6 months.[1, 6] | The 505 AutoWash setup requires a hard-surface floor, at least four feet from stairs and ample room for entry/exit. Its care chart calls for bin, brush, contact, sensor, filter, caster and edge-brush care, plus rinsing clean/dirty tanks, cleaning the pad-washing basin every two weeks or as needed, cleaning the blower cover monthly and replacing bags when prompted.[2, 7] |
What this changes: The 505 moves pad washing/drying into the dock but adds tanks, a basin and recurring dock-care tasks. The 105 avoids those AutoWash tasks but leaves bin and mop-pad handling to the owner. Choose according to which work you would rather perform and whether the 505's placement conditions fit.[1, 2, 6, 7] The better fit depends on your priorities | ||
Best for your routine
Minimize routine emptying and mop-pad washing/drying
Best fit: Roomba Plus 505 Combo
Based on listed features, not comparative testing.
The 505's AutoWash dock documents automatic emptying, pad washing, heat drying and self-cleaning; the exact 105 box contents list a charge-only dock.
Prefer a charge-only dock with fewer documented dock functions
Best fit: Roomba 105 Combo
Based on listed features, not comparative testing.
The 105's charge-only dock avoids the 505's AutoWash tanks and basin; the 105 still requires owner-managed bin and mop-pad care.
Mop around carpeted areas with less manual pad management
Best fit: Roomba Plus 505 Combo
Based on listed features, not comparative testing.
Both models document carpet avoidance while mopping, but the 505 additionally documents automatic pad lifting and dock pad care.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
If the 505 costs more when you compare current offers, evaluate that difference against its documented AutoWash automation, dual spinning mop hardware, pad auto-lift and added obstacle recognition—not an assumed percentage improvement in cleaning.
The available price history covers only a short recent window, so it can show current offers but cannot support a historical-low or definite Buy Now/Wait recommendation.
Is the upgrade worth it?
Worth considering if
- Frequent mopping where pad handling is a recurring chore.
- Homes with enough hard-floor dock clearance and owners willing to maintain tanks, brushes, filters and bags.
- Shoppers who specifically value documented obstacle recognition and automatic pad lift as feature fit.
Skip the upgrade if
- You want the simplest charge-only setup or cannot provide the 505's required hard-floor clearance.
- You rarely mop and would not use the 505's pad-washing workflow.
- You are buying only for a promised real-world cleaning or reliability advantage that the available evidence does not establish.
Community discussions
Questions and individual experiences add context, not controlled-test results, failure rates, or owner consensus.
105 owners discuss slow or wet mopping reports
A Roomba 105 Combo discussion raises slow mapping and overly wet mopping as questions; the exact Y314020 bundle is not confirmed. Comments mention the 505 and include a contrary report of normal straight-line operation, so this is mixed-scope reader context rather than a head-to-head result.

Limitations
- This is a source-backed comparison, not a Pickoryx hands-on test.
- iRobot's 105 page contains a generic AutoEmpty dock reference in descriptive copy, but the exact Y314020 'What's in the box' section lists a Charge-Only Dock. The exact bundle identity controls this comparison; confirm the retailer package before purchase.
- The 105 care page has conflicting bin instructions: one section says not to rinse or soak the bin while another says to rinse it with warm water during filter cleaning. Follow the exact owner's guide or iRobot support before adding water to this bundle's bin.
- The supplied price history is short, so no historical-low, savings baseline or purchase-timing conclusion is made.
- No bilateral independent test was found for pickup, stain removal, noise, battery life, navigation success rate or durability; these remain open questions rather than product conclusions.
- The three linked Reddit discussions are contextual owner anecdotes only; they do not support product claims, performance winners, reliability rates or the purchase recommendation.
Questions shoppers ask
Does the Roomba 105 Combo include an AutoEmpty or AutoWash dock?
For the exact Y314020 bundle assigned here, iRobot's product page lists a Charge-Only Dock in the box. The 105 family also appears in broader support material with multiple dock configurations, so verify the specific retailer bundle rather than relying on a series name.
Will either robot mop carpets?
iRobot says both models avoid carpets while mopping. The 505 additionally describes mop-pad auto-lift when carpet is sensed; this is a documented feature difference, not proof of better carpet detection in every home.
Is the 505 maintenance-free because it has AutoWash?
No. iRobot still calls for routine bin, tank, contact, brush and filter care, and its accessory guidance identifies filters, brushes and the rubber brush as replaceable maintenance parts.
Can this comparison prove that the 505 cleans better?
No. The official pages document features and marketing comparisons, but this review found no applicable bilateral independent test for pickup or stain removal. Treat the 505 as a feature-fit choice for automation, not a proven performance winner.
Methodology and sources
Compared the exact Y314020 and N185020 bundles on dock work removed or retained, mopping hardware and carpet handling, navigation features, dock placement and documented owner care. Linked owner discussions were checked for reader context only; real-world performance and reliability remain unanswered because no comparable independent testing was found for both products.
Automated research assistance organized the exact product records, source references and a bounded set of owner discussions; it did not test either robot, claim ownership or infer real-world performance from marketing copy.
