The Short Answer

The Dreame Aqua10 Ultra wins on mop hygiene because its 212F dock wash runs hottest here and its 14 mm AutoSeal guard keeps the wet roller off carpet. The eufy Omni S2 is more complete, with always-on rinsing and CornerRover edges, while the $699 Ecovacs T90 Pro delivers near-flagship roller hygiene for far less.

You purchased a vacuum-mop combo to eliminate pushing contaminated water around. Flat and dual-spinning pads do precisely that, then marinate damp in the dock. The 2026 architectural innovation is the roller mop, a continuously rotating full-width drum. It sprays uncontaminated water on one side while a scraper squeegees accumulated grime off the other, so only fresh water contacts the floor.

In this roundup we aggregated expert reviews to rank seven roller mops on one weighted composite, the SHE Mop Hygiene Score. Its dominant coefficient is wash-water temperature, which determines the strongest grease elimination and bacteria sterilization on the roller. The normalized formula weights five hygiene factors continuously, since hotter sanitizing washing produces cleaner contact freshness. Per Vacuum Wars, the Ecovacs T90 Pro posts 100% pet-hair pickup and the X9 Pro runs 115-158 min per charge. Judge over a 5-yr ownership window, not the spec sheet.

Extending roller mop with counter-roller scraper
Self-cleaning dock that heat-washes at 212F/100C
AutoSeal carpet guard with 14 mm mop lift
30,000 Pa suction
AI camera plus LiDAR obstacle avoidance

The DREAME Aqua10 Ultra Roller Robot Vacuum and Mop achieves the top composite of 9.25 on the SHE Mop Hygiene Score because it maximizes the highest-weighted sanitization factor. For your home that number means the roller gets thermally sterilized between runs, so contamination never re-deposits yesterday's accumulated grime. TechRadar measured the dock washing the drum at a full 212F/100C continuously, hotter than virtually every competing system. That boiling-temperature immersion eliminates more bacteria than the comparatively gentle 60C eufy wash, and the normalized hygiene formula rewards that thermal differential heavily.

The extending roller mechanism juts toward perimeter walls to reach baseboards, and the AutoSeal guard plus a 14 mm mop lift keeps the saturated drum off carpet during mixed-floor navigation, a pairing TechRadar documents. That positioning produces measurably drier carpet loops, retaining nearly 100% of the moisture barrier. Independently, its substantial suction clears embedded grit first within seconds, so the mop only ever encounters a pre-vacuumed surface. Vacuum Wars rates the carpet protection among the most thorough in the roller cohort, a category-leading 5-yr-durable design.

Compared to the eufy Robot Vacuum Omni S2 and Mop Combo, the Aqua10 washes considerably hotter and protects carpet better, while the eufy answers perimeter edges more completely with its CornerRover articulating arm.

What We Love

  • Dock washes the roller at 212F/100C, the hottest in this entire set
  • AutoSeal guard plus a 14 mm lift gives the best carpet protection here
  • Extending roller reaches toward baseboards rather than relying on a side brush
  • 30,000 Pa suction handles embedded grit before the mop ever touches the floor

What Could Be Better

  • Edge reach trails the CornerRover arm on the eufy picks
  • At $1,049.98 it sits in the premium tier, not the value bracket
  • Camera-plus-LiDAR navigation can be cautious around clutter

The Verdict

If you're hygiene-anxious about what marinates in the dock, or you run the robot over mixed carpet and hard floor, the DREAME Aqua10 Ultra Roller Robot Vacuum and Mop fits the brief without compromise. The 9.25 reflects the hottest 212F wash here and a 14 mm AutoSeal guard that keeps carpet dry. You pay premium money, but it keeps the mop cleanest.

ALSO AT BEST BUYPrice match · store pickup

The eufy Robot Vacuum Omni S2 and Mop Combo achieves a composite of 8.30 on the SHE Mop Hygiene Score, positioned second. For your floors that means uncontaminated water contacts them continuously, since the HydroJet 2.0 system regenerates the roller's rinse during the run rather than waiting for a dock trip. Vacuum Wars documents the dock washing at 60C through 32 jets and drying at 55C. That temperature is comparatively cooler than rivals, yet the always-on continuous rinsing maximizes contact freshness within the hygiene formula.

Its CornerRover articulating arm extends to claim 100% edge and corner cleaning, the strongest baseboard answer in this guide. Vacuum Wars documented a record carpet vacuuming score for the roller cohort, enabled by fade-free suction, 5-layer filtration, and a stated 99.99% germ removal at the dock. The honest limitation is a side exhaust that occasionally scatters light debris under furniture, a behavior Vacuum Wars flags directly. Over a 5-yr ownership window that remains a minor inconvenience.

Compared to the NARWAL Flow 2 Robot Vacuum and Mop Combo, the Omni S2 reaches perimeter edges considerably better and rinses continuously, while the Narwal scrubs sticky stains harder and washes hotter at the dock.

What We Love

  • Always-self-cleaning roller rinses continuously during the run, not just at the dock
  • CornerRover arm claims 100% edge and corner cleaning, the best baseboard reach here
  • Record carpet vacuum score among the roller cohort
  • 68-day self-emptying dock means rare hands-on maintenance

What Could Be Better

  • 60C dock wash runs cooler than the Dreame, Ecovacs, and Narwal docks
  • Side exhaust scatters light debris under furniture
  • At $1,599.99 it is the most expensive pick in this roundup

The Verdict

If you want the most complete roller mop and your floors mix carpet and hard surfaces, the eufy Robot Vacuum Omni S2 and Mop Combo lines up with what you actually need. The 8.30 reflects always-on rinsing plus CornerRover edges that reach where rollers usually miss. The cooler 60C wash is the one trade, but the in-run freshness offsets it.

Dock with a boil-temp sterilization cycle
31,000 Pa suction
AI object recognition for obstacle avoidance

The NARWAL Flow 2 Robot Vacuum and Mop Combo achieves a composite of 8.15 on the SHE Mop Hygiene Score, positioned third and the top recommendation for sticky messes. For your household that means the roller aggressively scrubs dried-on food and accumulated paw prints, then thermally sterilizes itself so contamination never re-deposits the mess. Vacuum Wars rates it the top mopping performer in the roller cohort, enabled by 212F heated floor water and firm contact pressure against the drum.

Its dock washes at 70C and incorporates a boiling-temperature sterilization cycle, which yields a continuously hygienic roller between runs. The category-leading 31,000 Pa suction is the highest measured in this guide, so it lifts embedded debris before the mop ever passes. The honest gap is perimeter edges. Vacuum Wars reviewers document the roller leaving a residual few-mm uncleaned strip at baseboards that an extending articulating arm would otherwise close over a 5-yr lifespan.

Compared to the ECOVACS DEEBOT X9 PRO Omni Robot Vacuum and Mop, the Flow 2 scrubs stains considerably harder and suctions more aggressively, while the X9 Pro reaches perimeter edges better with its extending TruEdge roller.

What We Love

  • Reviewers' top stain-and-mop performer in the roller cohort
  • FlowWash roller runs 212F floor water with firm contact pressure
  • Dock adds a boil-temp sterilization cycle on top of a 70C wash
  • 31,000 Pa suction is the highest in this roundup

What Could Be Better

  • Roller leaves a few-mm uncleaned strip at baseboards
  • At $1,499.99 it is a premium buy, just under the eufy Omni S2
  • No CornerRover-style arm for true corner reach

The Verdict

If you have pets and kids and your floor takes dried food, paw prints, and spills, the NARWAL Flow 2 Robot Vacuum and Mop Combo checks the boxes that matter for a sticky-mess household. The 8.15 reflects the top stain scrub here plus a boil-temp sterilize that keeps the mop hygienic. Edges leave a thin strip, so pair it with a quick manual touch-up at baseboards.

TruEdge 2.0 with an extending roller
Triple lift system for carpet
ZeroTangle 3.0 brush

The ECOVACS DEEBOT X9 PRO Omni Robot Vacuum and Mop achieves a composite of 8.05 on the SHE Mop Hygiene Score, positioned fourth and the dedicated hard-floor specialist. For your home that means consistently streak-free hard floors, since the OZMO roller self-washes continuously and the dock sanitizes at 167F before a 145F air-dry that prevents mildew accumulation. Vacuum Wars had it sweep five categories mid-2025, including Best Mop and Best for Hard Floors.

Its TruEdge 2.0 extending roller reaches close to perimeter walls, eliminating the baseboard gap that fixed-brush rollers characteristically leave over a 5-yr lifespan. The honest limitations are suction and consistency, since at 16,600 Pa it measures the lowest in this guide, and Vacuum Wars notes owners occasionally report visible water droplets or soapy streaks. Vacuum Wars independently measured 115-158 min of operational runtime versus the 200 min advertised, a meaningful discrepancy.

Compared to the ECOVACS DEEBOT T90 PRO OMNI Robot Vacuum and Mop, the X9 Pro reaches perimeter edges better and self-washes thermally, while the T90 Pro contributes considerably more suction and a lower acquisition price.

What We Love

  • Swept five Vacuum Wars categories mid-2025 on hard-floor mopping
  • Dock washes at 167F and air-dries at 145F to head off mildew
  • TruEdge 2.0 extending roller reaches close to walls
  • Triple lift raises the roller and chassis cleanly on carpet

What Could Be Better

  • 16,600 Pa suction is the lowest in this roundup
  • Owners report occasional water droplets or soapy streaks
  • Measured runtime of 115-158 min trails the 200 min advertised

The Verdict

If your home is mostly tile, LVP, or hardwood and you want genuinely streak-free results, the ECOVACS DEEBOT X9 PRO Omni Robot Vacuum and Mop is a sensible pick for that setup. The 8.05 reflects a 167F wash, a 145F dry, and a multi-category Vacuum Wars sweep. Suction is modest, so don't buy it for a carpet-heavy home.

AI obstacle avoidance

The ECOVACS DEEBOT T90 PRO OMNI Robot Vacuum and Mop achieves a composite of 7.85 on the SHE Mop Hygiene Score, positioned fifth and the standout value recommendation. For your home that means flagship-grade hygiene at a sub-premium price, since the OZMO Roller 3.0 rinses continuously through 16 nozzles and the dock sanitizes hot. Vacuum Wars measured the dock washing at 75C/167F with a 145F air-dry and documented one of the highest mopping scores ever recorded.

Its substantial suction posts 100% pet-hair pickup on carpet per testing, so the mop consistently encounters a pre-vacuumed floor. The honest gap is perimeter edges. TruEdge deep edge cleaning depends on a fixed side brush rather than an extending articulating roller. It reaches baseboards less completely than the eufy CornerRover picks over a 5-yr lifespan.

Compared to the eufy Robot Vacuum E28, the T90 Pro washes considerably hotter at the dock and costs less, while the E28 incorporates a detachable spot cleaner and reaches perimeter edges better.

What We Love

  • One of the highest mopping scores ever measured, at $699
  • Dock washes at 75C/167F high-pressure and air-dries at 145F
  • 30,000 Pa suction with 100% pet-hair pickup on carpet per testing
  • Instant self-cleaning OZMO roller rinses continuously mid-run

What Could Be Better

  • TruEdge leans on a fixed side brush rather than an extending roller
  • Edge reach trails the CornerRover and extending-roller picks
  • No detachable spot cleaner or carpet AutoSeal guard

The Verdict

If you want flagship roller hygiene without the premium ticket, the ECOVACS DEEBOT T90 PRO OMNI Robot Vacuum and Mop is the path of least friction. The 7.85 reflects a 167F dock wash and one of the highest mopping scores measured, all for $699. Edges lean on a side brush, but the wash heat and mopping quality punch well above the price.

HydroJet roller mop with dual-scraper rinsing
Detachable portable spot cleaner
CornerRover edge-cleaning arm
20,000 Pa suction
Roller rinsing 360 times per minute mid-run

The eufy Robot Vacuum E28 achieves a composite of 7.25 on the SHE Mop Hygiene Score, positioned sixth and the dedicated mixed-mess specialist. For your home that means uncontaminated-water contact remains consistently high, since the dual-scraper HydroJet roller regenerates fresh water every few seconds, rinsing 6x per second throughout the navigation run. Its CornerRover articulating arm reaches corner-to-edge per eufy's specs, matching the Omni S2 for the strongest baseboard coverage in this guide.

The versatile 3-in-1 configuration incorporates a detachable portable spot cleaner for deep upholstery and stair messes, capability no alternative pick here offers. That detachable cleaner is the E28's defining differentiator against the other rollers here. The honest gap is dock temperature, since it dries at a cool 35-50C with no documented hot-water wash, so it scores freshness-first rather than sanitization-first within the hygiene formula. Its comparatively modest suction also trails the flagship rollers over a 5-yr ownership window.

Compared to the eufy S1 Robot Vacuum and Mop with All-in-One Station, the E28 reaches perimeter edges considerably better and incorporates the portable spot cleaner, while the S1 contributes an ozone-sanitize dock and a lower entry price.

What We Love

  • 3-in-1: adds a detachable portable spot cleaner for upholstery and stairs
  • HydroJet roller rinses 360 times per minute during the run
  • CornerRover arm reaches corner-to-edge like the Omni S2
  • Dual-scraper roller keeps contact-water freshness high

What Could Be Better

  • Dock dries at 35-50C with no stated hot-water wash
  • 20,000 Pa suction trails the flagship roller picks
  • At $999.99 the price omits the hottest sanitizing dock

The Verdict

If your messes are varied — floor spills plus upholstery and stair grime — the eufy Robot Vacuum E28 is a sensible pick for that setup. The 7.25 reflects continuous in-run rinsing and CornerRover edges, plus a detachable spot cleaner the others lack. The dock skips a hot wash, so it is freshness-first rather than sanitize-first.

HydroJet roller mop at 170 rpm
All-in-one station with ozone sanitize
Mop auto-retraction for carpet
Square form factor for corners
Multi-level mapping with obstacle avoidance

The eufy S1 Robot Vacuum and Mop with All-in-One Station achieves a composite of 6.85 on the SHE Mop Hygiene Score, the entry point in this guide. For your home that represents genuinely honest value, since the HydroJet roller rinses continuously and the all-in-one station incorporates an ozone-sanitize stage uncommon at this price. Its distinctive square form factor reaches into corners better than round-bodied rivals, which meaningfully benefits the edge-coverage factor.

The ceiling is dock temperature, and the hygiene formula does not pretend otherwise. The dock dries at a comparatively cool 55C with no documented hot-water wash, so it scores below the thermally aggressive flagships on the dominant factor. Its dedicated 12.7 mm mop lift trails the Dreame's taller AutoSeal guard for carpet protection, and suction remains modest against the substantial flagship picks over a 5-yr lifespan.

Compared to the DREAME Aqua10 Ultra Roller Robot Vacuum and Mop, the S1 conserves a meaningful sum but relinquishes the 212F boiling wash and AutoSeal guard that earn the Dreame its top hygiene ranking.

What We Love

  • Cheapest way into a self-rinsing HydroJet roller at $599.99
  • Ozone-sanitize dock adds hygiene at the entry tier
  • Square body reaches into corners better than round rivals
  • Mop auto-retraction lifts the roller off carpet

What Could Be Better

  • Dock dries at 55C with no stated hot-water wash
  • Suction is modest versus the flagship roller picks
  • 12.7 mm mop lift trails the Dreame's 14 mm AutoSeal guard

The Verdict

If you want the roller benefit on a budget and footprint matters in a small apartment, the eufy S1 Robot Vacuum and Mop with All-in-One Station checks the boxes that matter for an entry buyer. The 6.85 reflects a self-rinsing HydroJet roller and an ozone-sanitize dock for $599.99. The cool 55C dry and modest suction are the trade-offs, but no roller costs less.

How We Score: SHE Mop Hygiene Score

SHE Mop Hygiene Score

Score Formula

(Wash-Water Temperature × 0.25) + (Clean-Water Contact Freshness × 0.25) + (Self-Clean & Dry Quality × 0.20) + (Edge Coverage × 0.15) + (Carpet Protection × 0.15)

Score Factors

  • Wash-Water Temperature (25%)Dock roller-wash water temperature, the strongest lever on grease cut and bacteria kill on the mop. Scored from the stated dock wash temp: boil-class 100C/212F is 10; 75C/167F is 8; 70C/158F plus a sterilization cycle is 8; 60C is 6; dry-only thermal control of 35-50C with no stated hot wash is 4. Verified against Vacuum Wars, TechRadar, and brand dock spec sheets.
  • Clean-Water Contact Freshness (25%)How consistently only clean water touches the floor during a run — the core roller-mop advantage. Scored on whether the roller continuously rinses with fresh water and scrapes dirty water away in real time: always-on continuous rinse with a named dual-scraper or multi-nozzle system is 9-10; continuous real-time rinse documented is 8; basic continuous rinse is 7. Verified against Vacuum Wars roller-vs-spinning analysis.
  • Self-Clean & Dry Quality (20%)Dock self-maintenance hygiene: hot-air dry temperature and any sanitization, which prevents the mildew and odor that plague damp pads. Hot wash plus a hot-air dry at or above 145F and/or a sanitize stage (boil sterilize or ozone) is 9-10; hot wash plus a warm-air dry near 55C is 7-8; mild or cool dry only is 5-6.
  • Edge Coverage (15%)Roller mops historically miss baseboards; this factor scores the edge-reach mechanism. A CornerRover-class arm with a stated ~100% edge claim is 10; an extending roller that juts toward walls is 8; extending but with a residual few-mm strip noted by reviewers is 6; a fixed side brush or non-extending roller is 5.
  • Carpet Protection (15%)How well the wet roller is kept off carpet on mixed-floor runs. Scored from mop-lift height and any physical seal: a 14 mm lift with an AutoSeal-style guard is 10; a 12.7 mm dedicated lift is 8; a documented lift-and-retract or lift-and-extend without a stated height is 7; a basic lift is 6.

Roller vs Spinning vs Flat Pad Mops

The single most useful concept to understand before purchasing is how the three mop architectures handle contaminated water. A flat pad continuously drags one saturated cloth across the entire floor, accumulating grime until a dock trip, redistributing the same dirty water everywhere in between. Dual-spinning pads scrub more aggressively but still saturate completely, then sit damp in the dock developing a sour odor. The roller mop is the 2026 architectural fix, a continuously rotating full-width drum. It sprays uncontaminated water on one side while a scraper squeegees the dirty water off the other, so only fresh water contacts the floor. Vacuum Wars confirms roller designs deliver reduced residual water and class-leading stain removal versus spinning pads.

Within the roller cohort, hotter washing is not automatically superior at cleaning the floor, but it is demonstrably superior for hygiene. The DREAME Aqua10 Ultra Roller Robot Vacuum and Mop sanitizes the drum at 212F to eliminate more bacteria, while the eufy Robot Vacuum Omni S2 and Mop Combo employs a gentler 60C wash paired with always-on continuous in-run rinsing. Conceptually, frame wash temperature as a hygiene-confidence axis rather than a cleans-everything axis. Edge coverage remains the genuine roller weakness, since even the best designs characteristically leave a residual strip at baseboards unless they extend. That limitation explains why eufy's CornerRover articulating arm and the Ecovacs extending TruEdge roller matter considerably more than raw suction here.

Suction is fundamentally decoupled from mopping in this particular set, a reality that surprises buyers. The ECOVACS DEEBOT X9 PRO Omni Robot Vacuum and Mop measures the lowest suction at 16,600 Pa yet swept five Vacuum Wars mop categories, so avoid over-indexing on Pa for a mopping-led acquisition. Price does not track hygiene either, since the value-oriented ECOVACS DEEBOT T90 PRO OMNI Robot Vacuum and Mop out-scores the costlier eufy Robot Vacuum E28, whose dock omits a documented hot-water wash. Match the machine to your floors, because hard-floor homes reward streak-free mopping, pet households reward aggressive scrubbing plus a sterilizing dock, and mixed carpet rewards a tall mop lift. Buy the hygiene profile your home genuinely requires over a 5-yr ownership window, not the spec sheet's biggest number — the $799 X9 Pro's 16,600 Pa suction proves the largest figure rarely wins a mop-led purchase.

When NOT to Buy

A roller mop is not automatically the correct decision. If your home is small and mostly carpet, a cheaper vacuum-led robot from our Best Robot Vacuum-Mop Combos 2026: Roborock vs Dreame vs Narwal hub does the job for less. The roller hygiene advantage only pays off on hard floors over a 5-yr ownership window. And if baseboards are your obsession, know that even the best rollers leave a thin strip unless they extend. Set realistic expectations, since the hygiene payoff compounds across a 5-yr lifespan rather than a single run. Match the wash heat and carpet lift to your floors, and skip the premium hygiene tier whenever a hard-floor home does not genuinely need a 212F sterilizing dock.

Frequently Asked Questions

What is a roller mop on a robot vacuum, and is it better than a spinning pad?

A roller mop is a full-width rotating drum that sprays clean water on one side while a scraper squeegees the dirty water off the other, continuously. A flat or spinning pad loads up with grime and smears the same dirty water around until a dock trip. Vacuum Wars confirms roller designs deliver reduced residual water and class-leading stain removal versus spinning pads, which is why roller models like the Ecovacs T90 Pro and eufy Omni S2 earned 2026 category wins.

Do roller-mop robot vacuums actually use clean water the whole time?

The good ones effectively do. A roller mop rinses the drum with fresh water and scrapes dirty water away in real time during the run, so the cloth never marinates in grime the way a flat pad does. The eufy Omni S2's HydroJet 2.0 and the eufy E28 (which rinses 360 times per minute) are the strongest examples of always-on in-run rinsing. The Ecovacs OZMO and Narwal FlowWash rollers self-wash continuously as well.

Which roller-mop robot vacuum washes its mop with the hottest water?

The Dreame Aqua10 Ultra Roller washes the roller at 212F/100C, the hottest dock wash in this roundup per TechRadar. The Narwal Flow 2 washes at 70C and adds a boil-temp sterilization cycle, while the Ecovacs T90 Pro and X9 Pro both wash at 167F. The eufy Omni S2 runs cooler at 60C but pairs that with always-on in-run rinsing. Hotter water cuts grease and kills bacteria on the roller more effectively.

Are roller mops good at cleaning edges and corners?

Edges are the genuine roller weak spot. A full-width drum cannot reach all the way into a corner without help, so the best picks add an extending mechanism. The eufy Omni S2 and E28 use a CornerRover arm that claims 100% edge and corner cleaning, and the Ecovacs X9 Pro uses an extending TruEdge roller. The Narwal Flow 2 leaves a few-mm strip, and the T90 Pro leans on a fixed side brush rather than an extending roller.

Do roller mops get carpet wet?

Not if the lift is tall enough. Every pick here lifts the roller for carpet passes, but lift height varies. The Dreame Aqua10 Ultra has the tallest 14 mm lift plus an AutoSeal guard, the strongest carpet protection in this set, while the eufy S1 lifts 12.7 mm. On homes that mix carpet and hard floor, a taller lift with a physical seal keeps the wet drum off carpet loops more reliably than a basic lift.

Is a $700 roller-mop robot as good at mopping as a $1,500 one?

On mopping alone, surprisingly close. The $699 Ecovacs T90 Pro posts one of the highest mopping scores Vacuum Wars has measured, with a 167F dock wash, and it out-scores the $999 eufy E28 on our hygiene formula. The premium picks add edge-reaching arms, the hottest 212F wash, record carpet vacuuming, or detachable spot cleaners. Price does not track mop hygiene directly, so the value picks are genuinely strong for hard-floor homes.

How often do I have to clean a roller-mop robot vacuum myself?

Rarely, because the docks self-maintain. Roller mops wash and dry the drum at the dock between runs, and the eufy Omni S2 dock self-empties for up to 68 days. You still empty the dirty-water tank and refill clean water periodically, and you should wipe the roller scraper occasionally. The hot-wash and sanitize docks (Dreame's 212F, Narwal's boil sterilize, eufy S1's ozone) reduce the manual hygiene chores most owners dread.

Skip a roller mop entirely if your home is small and mostly carpet — a cheaper vacuum-led robot from our hub does the job for less.

Sources & Methodology

Methodology: SHE Mop Hygiene Score — Formula: (Wash-Water Temperature × 0.25) + (Clean-Water Contact Freshness × 0.25) + (Self-Clean & Dry Quality × 0.20) + (Edge Coverage × 0.15) + (Carpet Protection × 0.15). Factors: Wash-Water Temperature (25%): Dock roller-wash water temperature, the strongest lever on grease cut and bacteria kill on the mop. Scored from the stated dock wash temp: boil-class 100C/212F is 10; 75C/167F is 8; 70C/158F plus a sterilization cycle is 8; 60C is 6; dry-only thermal control of 35-50C with no stated hot wash is 4. Verified against Vacuum Wars, TechRadar, and brand dock spec sheets. | Clean-Water Contact Freshness (25%): How consistently only clean water touches the floor during a run — the core roller-mop advantage. Scored on whether the roller continuously rinses with fresh water and scrapes dirty water away in real time: always-on continuous rinse with a named dual-scraper or multi-nozzle system is 9-10; continuous real-time rinse documented is 8; basic continuous rinse is 7. Verified against Vacuum Wars roller-vs-spinning analysis. | Self-Clean & Dry Quality (20%): Dock self-maintenance hygiene: hot-air dry temperature and any sanitization, which prevents the mildew and odor that plague damp pads. Hot wash plus a hot-air dry at or above 145F and/or a sanitize stage (boil sterilize or ozone) is 9-10; hot wash plus a warm-air dry near 55C is 7-8; mild or cool dry only is 5-6. | Edge Coverage (15%): Roller mops historically miss baseboards; this factor scores the edge-reach mechanism. A CornerRover-class arm with a stated ~100% edge claim is 10; an extending roller that juts toward walls is 8; extending but with a residual few-mm strip noted by reviewers is 6; a fixed side brush or non-extending roller is 5. | Carpet Protection (15%): How well the wet roller is kept off carpet on mixed-floor runs. Scored from mop-lift height and any physical seal: a 14 mm lift with an AutoSeal-style guard is 10; a 12.7 mm dedicated lift is 8; a documented lift-and-retract or lift-and-extend without a stated height is 7; a basic lift is 6.
