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.

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.

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.

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.

Light, nimble steering with a swiveling head makes it easy to turn into corners and reach tight areas; handling can become harder on thick carpet because suction makes the head ‘stick’.

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.

Very maneuverable with swiveling heads and good weight distribution for steering around furniture and tight spots; the top-heavy, in-hand weight can still fatigue the arm during long whole-home cleans.

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.

Hot-water pad washing and AI stain/spot modes help it revisit and scrub stubborn areas; demos show it taking on dried messes like ketchup with repeated passes and mid-run pad rinses.

Consistently among the top performers on dried-on stains in side-by-side tests, especially when using steam mode.

Dried-on stain removal scored 116 in testing, clearly above the current average of about 101.

Handles dried-on stains very well, often removing soy-type spots almost completely and finishing near the top of deep-cleaning tests.

Provides excellent cleaning on stubborn, dried stains despite lacking newer features.

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.

Owners find it can lift dried coffee and ketchup spills from hard floors, though tougher dried stains may require multiple passes to fully remove.

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.

Swivel steering and light weight make it easy to maneuver around furniture and tight spaces; reviewers describe it as handling well in normal use.

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.

Results show the Deebot T30S tied for third in dried stain removal in a multi-run coffee and grape-juice test, and other reviews also report strong performance on sticky or dried messes like ketchup and jelly. Some concentrated liquids can spread or leave lingering smell in pads, occasionally requiring manual pad washing.

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.

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.

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.

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.

Often praised as lightweight and highly maneuverable around furniture, but some floorheads have limited swivel and thick carpet can feel physically harder to push without airflow adjustment.

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. Multiple reviewers also praise strong stain removal, though some note it can struggle with the hardest set-in grime and may require deep-clean mode or extra passes.

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 dried-on stains well, achieving above-average removal even if some competitors edge it out in the toughest tests.

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.

Removes dried stains well but trails the steam equipped HydroSteam on the toughest spots.

Dried on foods mud and sticky residues typically come up in a few passes, especially when switching into max or ultra mode for a deeper scrub.

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.

Most reviewers find it follows well on four casters and is easy to pull along, with long reach reducing repositioning. Others dislike canister-style cleaning because the trailing body, cord and hose can snag and feel cumbersome.

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.
