All robot vacuums. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | Eureka J15 Ultra | Roborock Qrevo S Pro |
|---|---|---|
| Home size | ||
| Under 1,500 sqft | GoodCompact homes benefit from auto-dock refill and mop retraction; no range constraints for sub-1500 sqft single-floor layouts. | Good240-minute runtime and about 1,495 sq ft measured per charge easily covers compact layouts in one pass. |
| 1,500 – 3,000 | GoodIdeal fit range. Runtime and dock refill cadence scale well for 2-3 scheduled runs weekly across mixed floor types. | GoodIndependent testing measured roughly 1,495 sq ft cleaned per charge, enough for most homes in this range without a recharge stop. |
| Over 3,000 | DependsRequires multiple passes per cycle; runtime constraints may necessitate 2-3 sessions weekly for thorough coverage. | DependsAt about 1,495 sq ft measured per charge, homes above 3,000 sq ft likely need more than one charge cycle to finish. |
| Primary floors | ||
| Hard floors | GoodScrubExtend mopping targets hard floors; mop pads run continuously on sealed wood, tile, and vinyl. | Good18,500 Pa suction and automatically lifting mop pads clean bare floors without extra setup or manual pad removal. |
| Low / medium pile | GoodScrubExtend automatically retracts mop on detected low-pile carpet. Vacuuming performance is standard for the category. | GoodIndependent testing measured 81 percent carpet debris removal, matching the category average despite a single rubber main brush. |
| High pile / shagthey differ | PoorOwner reports on Eureka mop-combos document reduced suction effectiveness on deep shag carpet; dedicated vacuums recommended. | DependsThe single rubber main brush gives less mechanical agitation than a bristle brush, so thick high-pile carpet likely sees reduced pickup. |
| Mopping needs | ||
| Vacuum only | GoodStrong vacuum; the mop lifts or detaches when not needed. | GoodStrong vacuum; the mop lifts or detaches when not needed. |

A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
What the score is built from.
Nine inputs across three pillars, each weighted as shown and each scored so more is better. A robot can lead on one and trail on another, which is the point of showing them apart.

What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
Eureka J15 Ultra
Mopping adds capability but requires weekly mop-pad maintenance; one feature trades hands-off claims for consumable churn.
IntelliView pairs LiDAR with an RGB camera, an LED lamp and a line laser to recognize objects, so the obstacle avoidance runs on a camera operating inside the home. The recognition that keeps the robot off cables and pet waste is the same hardware a privacy-sensitive household has to accept.
Roborock Qrevo S Pro
This is a flagship-grade mop paired with a mid-pack brush: the dock out-cleans machines twice its price, and the main roller falls behind machines half its price on pet hair.
Structured-light obstacle avoidance caught only 5 of 24 test obstacles, so floors need clearing before a run that a stronger sensor suite would tolerate left alone.
Single rubber main brush: strong on bare-floor debris, prone to hair wrap in shedding-pet homes.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Eureka J15 Ultra
- Homes with primarily high-pile or deep carpet
- Mopping mechanism targets hard floors. Owner reports for Eureka mop-combos note reduced effectiveness on textured carpet; dedicated vacuums outperform here.
- Owners with spotty 2.4GHz-only Wi-Fi coverage
- Eureka J-series use 2.4GHz Wi-Fi exclusively. Homes with 5GHz-only networks or fragmented coverage require mesh upgrades or Wi-Fi extenders.
- Users requiring true Level IV autonomous operation
- Classification at Level III: operates in a mapped environment with occasional human intervention for edge cases. IntelliView recognizes and routes around known object types, but the robot does not adapt to settings outside the map it has been taught.
Roborock Qrevo S Pro
- Households with long-haired shedding pets
- Independent testing measured 43 percent pickup on flattened pet hair against an 82 percent category average, with 62 percent hair tangling on the main brush versus 26 percent average.
- Cluttered floors left unprepared before each run
- The same testing recorded avoidance of only 5 of 24 obstacles against a 16-obstacle average, so small items left on the floor are more likely to be pushed or picked up.
- Owners sensitive to loud dust-emptying cycles
- One reviewer measured about 70 decibels during the dock's self-emptying cycle, loud enough to be noticed over a television in the next room.
- Tight layouts with narrow furniture gaps
- A reviewer noted the robot's size limits maneuvering around furniture in tightly arranged rooms, a factor separate from its mapping or suction performance.
- Buyers who need aggressive deep-pile carpet agitation
- A single rubber main brush provides less mechanical agitation than a bristle-and-rubber combination brush, a documented design trade-off on thick, deep-pile carpet.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Eureka J15 Ultra
- Weekly: Rinse the mop pads by hand or run a dock wash cycle; check the side brush and FlexiRazor roller for hair wrap.
- Monthly: Clean the dust filter, rinse the station tray, and refresh the 4 L clean and 3.4 L dirty water tanks.
- Every 3-6 months: Replace the 3 L dust bag; Eureka rates one at roughly 75 days, the early edge of this window.
- Every 3-6 months: Replace the mop pads once the surface mats or frays; descale the station’s water circuit with an appliance descaler, not vinegar, if mineral buildup appears.
- Annually: Replace the FlexiRazor roller brush and the filter; replacement runs 6-12 months depending on hair load, and the anti-tangle roller is built to stretch that cycle.
- Annually: Inspect the dock gaskets and charging contacts for wear.
Roborock Qrevo S Pro
- Weekly: Check and refill the 4-liter clean water tank depending on mopping frequency.
- Weekly: Empty the 4-liter dirty water tank after mopping-heavy weeks.
- As needed: Clear tangled hair from the single rubber main brush; independent testing found tangling well above the category average in pet households.
- Monthly: Wipe down the arc-shaped anti-tangle side brush and check for debris buildup.
- Every 3-6 months: Replace the auto-empty dock’s 2.7-liter dust bag (multi-bag packs run roughly $15-25).
- Every 3-6 months: Swap mop pads and filter; third-party kits bundle both for roughly $25-30.
- Annually: Inspect and replace the side brush and main brush if worn (official parts run about $12-16 each).
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.

Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
