- ✓DirTect sensor auto-boosts on heavier messes so you don't fiddle with modes
- ✓180° lie-flat design reaches under low furniture
- ✓Hot 194°F self-clean and 5-minute hot-air dry keep the roller smell-free
- ✓Zero-tangle roller holds up well with pet hair

- ✗No published noise figure and limited smart/app functionality at this tier
Roborock F25 Ultra
- ✓Combined mop score of 151.5 in independent testing versus a 115-point category average
- ✓Unique dual heating: 356°F steam mode plus a separate 187°F hot-water mode for everyday use
- ✓5-minute self-clean cycle (356°F steam, 203°F hot-air dry) meaningfully reduces roller odor between uses
- ✓Leaves less residual moisture on floors than the category average, reducing streaking
- ✓Powered SlideTech 2.0 wheels keep it maneuverable despite the added weight
- ✗At 12.1 lbs it's noticeably heavier in hand than most competitors in this category
- ✗Base suction (1.05 kPa measured) actually runs below the 1.17 kPa category average
- ✗Steam and hot-water modes drain the battery to just 15-25 minutes, so whole-home cleans need Auto mode
- ✗Premium pricing for the category, and the dirty-water tank capacity isn't published
- ✗Hard floors only — no carpet cleaning capability
