Pros & cons
Roborock F25 Ultra

- ✓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
