Roomba Plus 505 Combo vs Roborock Qrevo S Pro: Which One Fits Your Cleaning Routine?
Both are vacuum-and-mop robots with rotating/liftable mopping hardware and docks that automate emptying, washing and drying. Roomba Plus 505 offers PerfectEdge pad extension, SmartScrub and PrecisionVision recognition, and wets its pads at the dock instead of carrying an onboard water tank. Qrevo S Pro refills its robot water tank automatically. Compare that water path, the sensing features, dock clearance and retained care with your home; these documented differences do not establish real-world cleaning or reliability superiority.

The buying question
Which documented edge-cleaning controls, sensing features, dock placement and retained care tasks fit the buyer's routine and space?
The Roomba Plus 505 documents edge-extending DualClean pads, SmartScrub and PrecisionVision AI, and iRobot says the 505 has no onboard water tank because its dock wets the pad. The Qrevo S Pro documents its own sensing, dock dimensions, maintenance sequence and automatic refill of its robot water tank. Both use rotating/liftable mopping hardware and dock wash/dry automation; the water-path difference can matter to a buyer, but none of these facts establishes a cleaning winner.
Quick verdict
Choose iRobot Roomba Plus 505 Combo Robot Vacuum & Mop with AutoWash Dock (N185020) if
- You want the Roomba's documented PerfectEdge pad extension and SmartScrub control for edge/corner cleaning, without turning those features into a stain-removal promise.
- You value PrecisionVision AI recognition of cords, shoes and pet waste as a feature fit, while understanding that success rates are unmeasured.
- You can provide the AutoWash dock's hard-floor placement and accept the documented bin, pad, brush, tank and filter care.
Choose Roborock Qrevo S Pro Robot Vacuum and Mop if
- You prefer the Qrevo S Pro's documented automatic robot-water-tank refill path, can meet its hard-flat dock clearance and maintenance sequence, and do not specifically need the Roomba's edge/scrub or recognition controls.
- The Qrevo S Pro's PreciSense LiDAR and Reactive Tech sensing fit your desired navigation feature set.
When the recommendation changes
- If edge and corner mopping control is the deciding need, the Roomba's PerfectEdge and SmartScrub features are the documented fit; this does not prove better stain removal.
- If you prefer an onboard robot-water-tank refill path rather than a dock-wetted pad, Qrevo is the documented fit; compare its care sequence and dock clearance, without treating that water path as proof of better cleaning.
- If your space cannot meet either dock's hard-floor and clearance requirements, the feature differences do not overcome the placement mismatch.
The differences that matter
Dock Automation
iRobot Roomba Plus 505 Combo Robot Vacuum & Mop with AutoWash Dock (N185020)
N185020 AutoWash documents debris auto-emptying, pad refreshing/washing, heated drying and self-cleaning. iRobot's compatibility guide says the 505 has no onboard water tank: its dock wets the pad before missions and adds clean liquid to the pad as needed.[1, 5]
What this changes: Both docks wash and dry mopping hardware, but the water path differs: 505 wets the pad at the dock with no onboard tank, while Qrevo refills its robot water tank. That is a workflow fit for buyers who care about where liquid is carried, not evidence of better hygiene, cleaning or workload.[1, 5, 6, 7]
Mopping System
iRobot Roomba Plus 505 Combo Robot Vacuum & Mop with AutoWash Dock (N185020)
Roomba Plus 505 documents DualClean spinning pads, PerfectEdge edge extension, SmartScrub, 200 RPM rotation, four modes and automatic pad lift when carpet is sensed.[1]
What this changes: Both use rotating mopping hardware with carpet-lift behavior. Roomba's documented edge extension and SmartScrub provide a specific edge/corner feature fit; neither source proves bilateral stain-removal or coverage superiority.[1, 6, 7]
Obstacle Avoidance
iRobot Roomba Plus 505 Combo Robot Vacuum & Mop with AutoWash Dock (N185020)
ClearView Pro LiDAR plus PrecisionVision AI is documented for recognition/avoidance of cords, socks and pet waste.[1]
What this changes: Both publish sensing features; no controlled bilateral result supports a real-world obstacle winner.[1, 6, 7]
Maintenance And Placement
iRobot Roomba Plus 505 Combo Robot Vacuum & Mop with AutoWash Dock (N185020)
Exact-series support documents removing the bin and filter, brushing the filter, emptying the bin, rinsing the bin only after removing the filter, and drying before reassembly. The product page also calls for rinsing dock tanks, cleaning contacts/brushes, replacing pads after 180 cleaning hours and replacing the filter every 3–6 months; the dock must sit on a hard floor at least 4 feet from stairs with navigation space.[1, 2, 3, 4]
Roborock Qrevo S Pro Robot Vacuum and Mop
The exact manual instructs emptying and rinsing the dirty-water tank, rinsing the cleaning tray and tray filter, rinsing the washable robot filter and air-drying it for at least 24 hours, cleaning/air-drying mop cloths, cleaning the main brush every 2 weeks, cleaning the side brush monthly, and replacing the mop cloths every 1–3 months, side brush every 3–6 months and main brush every 6–12 months. It specifies a hard-flat dock with at least 0.9 m height, 0.4 m width and 1.2 m depth.[7]
What this changes: Both docks remove some repeat visits but leave concrete owner actions. Choose the maintenance sequence and clearance that fit your routine; neither source establishes a lower total workload.[1, 2, 3, 4, 7]
Best for your routine
Prioritize iRobot's published edge-reaching pad and scrubbing controls
Best fit: iRobot Roomba Plus 505 Combo Robot Vacuum & Mop with AutoWash Dock (N185020)
Based on listed features, not comparative testing.
The Roomba Plus 505 page documents PerfectEdge pad extension and SmartScrub alongside DualClean spinning pads. This is a feature-fit preference, not proof of better stain removal.
Match the dock placement and retained care sequence
The better fit depends on your priorities
Both automate core dock wash/dry work, but 505 wets the pad at the dock while Qrevo refills its robot water tank; each also requires a different placement and hands-on care routine. Choose the package whose liquid path, hard-floor clearance and tank, filter, brush and mop actions fit the available space and time; this does not claim lower total workload.
Prefer an onboard robot-water-tank refill path
Best fit: Roborock Qrevo S Pro Robot Vacuum and Mop
Based on listed features, not comparative testing.
iRobot's compatibility guide says Roomba 505 has no onboard water tank and wets the pad at the dock, while the Qrevo manual documents robot water-tank refilling at the dock. This is a documented liquid-path difference, not a cleaning-performance or total-workload result.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
The available price difference is a dated clue only. Any premium should be justified by verified dock, mopping and sensing feature fit, not by an assumed percentage improvement in cleaning.
Price history is short for both products, so it is insufficient for a historical-low or definite Buy Now/Wait recommendation. Check the current offer at review time.
Community discussions
Questions and individual experiences add context, not controlled-test results, failure rates, or owner consensus.
Roomba 505 Plus dock-emptying discussion
A Roomba 505 Plus owner reports hearing an emptying cycle while debris remains in the robot bin and the dock bag stays empty. If dock automation is central to your choice, check debris transfer during setup and use the official troubleshooting or support route if it fails. The device history is unverified and the thread does not establish a failure rate.

Qrevo S Pro mopping setup discussion
A buyer of a “second chance” Qrevo S Pro reports dry streaks during early mopping runs. Replies discuss pad fit and water settings but also include other models and speculative repairs. Check the exact unit’s condition, official setup guidance and return/support terms; this account does not diagnose the cause or represent normal cleaning results.

Qrevo S Pro floor-type mapping discussion
A Qrevo S Pro discussion asks why mapped hardwood areas were not mopped when rugs were nearby; a reply points to assigning floor types in the map. Before buying, check floor labels, carpet-avoidance rules and room routines. This is one setup question, not evidence that the model systematically misses areas.

Limitations
- This is a source-backed comparison, not a hands-on test.
- The exact-model official pages provide feature and maintenance claims, not independent measurements of pickup, stain removal, noise, battery life, obstacle success, coverage or durability.
- Manufacturer figures and marketing comparisons remain manufacturer claims and are not converted into bilateral performance results.
- Both products require routine care despite dock automation; the documented task lists are not a guarantee of equal workload in every home.
- The N185020 product page does not state a wash temperature; the Qrevo S Pro page lists 167°F mop self-cleaning and 113°F warm-air drying, but that difference in published detail is not evidence of better hygiene, cleaning or workload.
- Current price observations cover short recent windows, so no historical-low, savings baseline or purchase-timing conclusion is made.
- Three community discussions are included as maintenance and workflow prompts only; they do not establish ownership, model history, cause, prevalence, performance, reliability or consensus.
Questions shoppers ask
Do both docks wash and dry the mop hardware?
Both docks wash and dry the mopping hardware. iRobot's compatibility guide says the 505 has no onboard water tank and that the dock wets the pad before missions and adds clean liquid as needed; Roborock's manual documents returning to refill the robot water tank, while its product page lists 167°F mop self-cleaning and 113°F warm-air drying. The N185020 page does not publish a wash temperature, and none of this establishes better hygiene or cleaning.
What maintenance remains after the dock runs?
For Roomba Plus 505, remove the bin filter before rinsing the bin, brush the filter, let parts dry before reassembly, rinse dock tanks and clean contacts/brushes; the pad is auto-washed after missions but is replaced after 180 cleaning hours, and the main brush is replaced about every 6–12 months. For Qrevo S Pro, empty/rinse the dirty-water tank, rinse the cleaning tray and tray filter, rinse the washable robot filter and air-dry it at least 24 hours, clean/air-dry mop cloths, clean the main brush every 2 weeks and side brush monthly, and replace mop cloths every 1–3 months, side brush every 3–6 months and main brush every 6–12 months. Both still require consumable and dock care.
Which one avoids obstacles better?
The official feature lists cannot answer that as a real-world winner. Roomba Plus 505 publishes PrecisionVision AI recognition/avoidance, while Qrevo S Pro publishes Reactive Tech sensing, but no controlled bilateral success-rate evidence was found.
Which one should I buy at today's price?
Use the current price as a dated clue and choose the feature workflow that fits your home. The short price histories do not support a Buy Now/Wait call or an all-time-low claim.
Methodology and sources
Compared the two exact models on dock automation, mopping system, obstacle-avoidance feature descriptions and documented care/placement implications. Reviewed seven candidate community discussions for model-scope context and selected three maintenance/workflow prompts. Kept real-world cleaning, navigation success and reliability unanswered because no bilateral independent evidence was found.
Automated research assistance organized product records and source references; it did not test either robot, claim ownership or infer real-world performance from marketing copy.
