Does the F25 Ultra work on carpet, or hard floors only?

It's built primarily as a hard-floor wet-dry vacuum with a mopping function, so like other machines in this category it isn't meant to clean carpets and rugs the way a dedicated vacuum or robot vacuum would - it's a complement to, not a replacement for, whole-home vacuuming.

How long does the battery actually last with steam mode on?

Testing found roughly 10 minutes of hot-water cleaning used about 30% of the battery, and 20 minutes in auto mode used about 40% - so a larger home's full cleaning session may need a mid-clean recharge if steam or hot water is used throughout.

How much maintenance does the mop pad need?

Even with the self-cleaning dock, owners still need to periodically hand-clean hair and debris off the mop pad after use, and the water tank needs refilling roughly every three uses on a typical home.

How does it compare to Tineco or Dreame's wet-dry vacuums?

The F25 Ultra's standout feature versus Tineco and Dreame flagships is its steam function (up to 302degF) for lifting dried-on grime, which most competing wet-dry vacuums handle with plain hot or cold water instead - the tradeoff is faster battery drain when steam is used heavily.

Is it worth it at full price?

Most buyers are better off waiting for a sale - it's regularly discounted from its roughly $800 list price down to the $500-600 range, which is a meaningfully better value given the maintenance tradeoffs of the category.

Can it get under couches or low furniture like a robot vacuum?

No - reviewers specifically noted it's heavy and bulky to maneuver over thresholds and doesn't fit under low furniture, so it's meant for open floor areas rather than the under-furniture reach a robot vacuum offers.

The F25 Ultra is the steam-and-hot-water flagship above the budget F25 BX already on this site, and it earns that price gap: independent testing scored its combined mopping at 151.5 points against a 115-point category average, with stain removal and residual-moisture numbers both beating the field. Unique to this tier are dual heating modes — 356°F VaporFlow steam for grease and grime, and 187°F WaveFlow hot water for everyday mopping — plus a self-cleaning cycle that hits 356°F steam and 203°F hot-air drying in about 5 minutes, which noticeably cuts the sour-roller smell that plagues cheaper wet-dry vacs. It still lies flat to reach under furniture and drives well despite the added weight, thanks to powered SlideTech 2.0 wheels. The honest tradeoffs: at 12.1 lbs it's heavier than most competitors in hand, base suction (1.05 kPa) actually measures below the category average, and running the heated steam or hot-water modes drains the battery to just 15-25 minutes — plan on Auto mode for whole-house sessions and save the specialty modes for spot-treating problem areas.

Owner Insights(32 discussions)

The F25 Ultra is Roborock's flagship cordless wet-dry vacuum, combining steam-assisted mopping with strong dry suction and a self-cleaning dock that handles the two most tedious parts of this category - emptying the bin and rinsing the mop head. It picked up a Better Homes & Gardens 2026 Clean House Award, which is a notable crossover endorsement for a product usually only covered in tech press.

Day to day, the combination of 22,000Pa suction and up to 302degF steam does real work on dried spills and kitchen grime in a single pass, and the DirTect sensor's automatic intensity adjustment means owners aren't manually toggling settings between hard floor and area rugs. The tradeoffs show up in battery life under heavy use - hot-water and steam modes eat through the battery fast enough that big homes will need to break a full clean into sessions - and in the unavoidable maintenance loop of refilling the tank every few passes and hand-cleaning the mop pad even with the self-cleaning dock running.

It's best suited for owners with mostly hard flooring and kids or pets generating regular spills and dried messes, who want one machine instead of separate vacuum and mop steps. At its current street price in the $500-600 range (down from an $800 list), it's positioned squarely against Tineco and Dreame's flagship wet-dry vacuums; Tineco's top-tier FLOOR ONE models are the closest alternative if steam heat specifically isn't a priority, typically running a bit less on suction wattage but with a comparable self-cleaning dock experience.

Pros

+The self-cleaning dock automatically empties dirt and dries the mop head between uses, cutting out the frequent manual-emptying step that makes cheaper wet-dry vacuums a chore
+It vacuums and mops the same pass instead of requiring two separate steps, which reviewers called out as a real time-saver for daily cleanups
+The DirTect Smart Sensor reads the surface and automatically adjusts cleaning intensity, so owners aren't manually switching modes between hard floor and rugs
+Tangle-free brush design specifically avoided sucking up cables during testing, a common failure point for cordless wet-dry vacuums used in home offices
+Build quality feels premium in hand thanks to ABS plastic and aluminum construction, described by one reviewer as sturdy and sleek rather than the cheap-feeling plastic common at this price
+It was named a winner in Better Homes & Gardens' 2026 Clean House Awards, a mainstream consumer-facing endorsement beyond typical tech-press coverage
+22,000Pa suction paired with steam up to 302degF (or 187degF hot water mode) tackles stuck-on kitchen grime that cold-water mop vacuums can't fully lift

Cons

−It's noticeably heavy moving across thresholds and too large to get under low furniture, so it's a floor-level cleaner rather than a full-house solution the way a robot vacuum is
−Corner cleaning fell short of the edge-to-edge coverage Roborock advertises, according to hands-on testing
−Battery drains fast in the hotter modes - about 10 minutes of hot-water cleaning used roughly 30% of the battery, and 20 minutes on auto mode used about 40%, meaning a full charge won't cover a large home in one pass
−The mop pad needs regular hand-cleaning of hair and debris after each use despite the self-cleaning dock
−The water tank needs refilling roughly every three uses, adding a maintenance step mid-cleaning-session for bigger homes
−Mop drying at the dock takes about 30 minutes, so it's not immediately ready for a second cleaning session right after use
