Dried stain tests now show the S1 Pro at or near the top of the pack, scrubbing away stuck-on messes like coffee, grape juice, and baked-on sauces within a few passes and leaving hard floors looking fully clean.
Roller mopping delivers exceptional dried on stain removal, clearing stubborn kitchen stains like dried coffee and muddy footprints faster than typical pad style robots and earning near record lab scores.
In dried-on stain tests, the P50 Pro Ultra scores well above average, clearing tough spills almost completely and outperforming both the P10 Pro Ultra and many premium rivals.
Steam-assisted cleaning lets the HydroSteam break up dried-on stains and sticky spills that non-steam models struggle with, making it a top pick for stubborn messes.
Reviews find the X10 Pro Omni unusually strong at removing dried-on messes like coffee and juice, often erasing stains completely with minimal passes compared with other robot mops.
In dried-on stain testing the L40 scores well above average and even outperforms both Dreame’s X40 and popular rivals like the Bissell CrossWave on stubborn spots.
Stain tests place the Qrevo Master just behind the S1 Pro, earning one of the highest scores for lifting dried coffee and grape spills over repeated runs.
Reviews find it removes dried on stains exceptionally well on carpets and upholstery, from cured mud and set drink spills to stubborn dirt, dried red wine and even dried animal urine, often matching or beating leading Bissell Hydrosteam and Revolution models in head to head tests.
Across multiple trials the Qrevo MaxV removes dried coffee and grape stains efficiently, securing a top tier stain score that ties it for fourth place among the flagship robots tested.
Updated stain testing finds the S8 Pro Ultra tied for fourth place, lifting most dried coffee and grape stains and even beating the newer S8 Max series in these mopping trials.
In the new stain tests the Freo X Ultra finishes fifth among the top performers, reliably erasing most dried coffee and grape stains even if it trails the very best robots slightly.
Results show the Deebot T30S tied for third in dried stain removal, clearing increasingly heavy coffee and grape stains better than many competing flagships.
Despite being an older model the L20 Ultra ties for third in dried coffee and grape stain tests, outperforming newer Dreame X30 and X40 robots on this metric.
Effectively sprays, scrubs, and extracts set-in stains (e.g., 5-day-old red wine, ketchup/mustard/soy sauce, and stubborn pet spots), usually clearing them after several focused passes; results depend on manual scrubbing since there’s no powered brush; extremely ground-in grime (like very dirty car mats) may take multiple refills and extended work.
Handles dried-on messes like coffee and even thick ketchup well, often needing multiple passes on tougher spots but ultimately lifting stains from sealed hard floors.
In dried on stain tests the roller mop removed most stuck on grime, scoring slightly above average and beating comparable pad based robots like the Saros 10.
The built-in spot cleaner removes dried-on stains like coffee and grape juice effectively after pretreating, and also performs well on fresh wet stains for quick upholstery and carpet touch-ups.
Handling is described as light and easy to steer, aided by a wheeled floorhead and ergonomic grip; reviewers mention smooth maneuvering around chair legs, tight areas, corners, and edges.
Self-righting ball base and 360 articulation improve stability and cornering, and many find it easy to steer; canister drag/bumping in tight hallways and pushback on thick rugs can take practice.
A major strength is handling: the older V8 form factor is repeatedly described as well-balanced and easy to maneuver with a swivel head and comfortable above-floor reach; on thicker carpet or rugs, max suction can make it feel stuck or harder to push.
Repeated tests on dried coffee, cola, sauce and other set-in spills show the dual-direction brush and strong suction can break up and lift many stuck-on messes in one or a few slow passes, while thicker fully dried ketchup/BBQ-style stains may take several passes and benefit most from Max Enhancement.
Smart Scrub and repeat-pass behavior remove many dried spills and muddy prints better than simple drag-pad mops; very heavy grime or sticky food may still need manual scrubbing.
Owners report that the machine can loosen and remove dried-on spills and food residues with a few slow passes, often clearing most stuck mess in a couple of strokes while sometimes needing extra attention for stubborn grit like sand.
Handling is usually described as easy thanks to light weight and swivel/tilt steering, helping around furniture and corners. Thick carpet/shag can be harder to push due to no height adjustment, and one review notes the unit can tip when using the hose.
The HydroJet roller and strong downward pressure remove many dried-on spills better than pad-based mops, but the stickiest stains (like dried ketchup) can still require multiple passes and may not match hot-water flagships.
Handles light dried-on stains in just a couple of passes and keeps pace with other Bissell uprights on tougher, set-in spots, especially when you pre-treat stains first.
Cleans light dried-on stains quickly and delivers solid results on tougher, set-in spots, though like most non-steam uprights it still benefits from stain pre-treatment for the worst messes.
Handles light dried-on stains well and delivers strong results on tougher set-in messes, though like other non-steam uprights it still benefits from stain pre-treatment for the worst spots.
In dried on stain tests the X50 Ultra earns a solid score around 80, putting its stain removal in line with other Dreame flagships and making it reliable for routine mopping duties.
Can remove minor set-in stains and some dried spills thanks to sonic/vibrating scrubbing, but stubborn sticky gunk may require multiple passes, pad rinsing, or a manual mop.
Removes light dried-on stains almost completely in a few passes, but on tougher set-in spots still needs many passes and can spread some residue, so overall results are only average compared with higher-powered models.
Stain removal on hard floors is generally impressive for typical dried splatters and sticky kitchen messes, but the toughest dried-on grime in crevices and very gummy residues like gum still tend to need extra effort or remain partly stuck, similar to other current vac-mops.
The wider head helps cover large areas faster but can be harder to maneuver into tight spaces, and the added heft reduces ergonomics compared with smaller Dysons. Reviewers generally find it usable and capable, but note comfort and tight-space handling suffer versus Gen5 Detect/V12.
On typical surface grime it can noticeably freshen tile, but its brush and pressure are not aggressive or deep-reaching enough to fully lift stubborn, set-in grout stains by themselves, so restorative work usually needs additional alkaline or acidic cleaners and hand scrubbing before the CrossWave rinses everything away.
