Roborock F25 Ultra Steam Wet Dry Vacuum

Overview

The Roborock F25 Ultra is the first wet-dry vacuum with both steam cleaning and hot water cleaning. It won the Better Homes & Gardens 2026 Clean House Award (selected from nearly 200 products), and TechRadar called it "far and away the most efficient" hard floor cleaner they've tested. If you have hard floors and want the most thorough clean possible without chemicals, this is the machine.

The F25 Ultra vacuums, mops with hot water, and steam-cleans in one pass. The 356F steam mode kills bacteria and lifts dried-on grime. The 187F hot water mode dissolves grease and sticky spills. You can switch between them depending on the mess. The self-cleaning dock washes the roller with steam or hot water and dries it with hot air, so the machine is ready for the next use without smelling terrible.

It competes directly with the Tineco Floor One S9 Artist and the Dreame H15 Pro. The Roborock wins on cleaning power and steam. The Tineco wins on design and battery life. The Dreame wins on baseboard cleaning with its retractable squeegee.

Key Features

The dual cleaning modes are the selling point. Steam mode heats to 356F and pushes steam through the roller to sanitize the floor. Hot water mode uses 187F water to dissolve grease and sticky messes. Craving Tech found both modes effective on kitchen spills and bathroom grime.

Suction is 22,000 Pa with 33N of downward pressure. The DirTect Smart Sensor monitors dirt levels in real time and adjusts cleaning intensity automatically. AI-assisted dual motors and SlideTech 2.0 power-assisted wheels make it easier to push around than most wet-dry vacs.

The FlatReach 2.0 design lets it lay almost flat (180 degrees) to clean under furniture as low as 12.5cm. Runtime is up to 60 minutes in Auto mode, covering roughly 500 square meters. The 1,000ml clean water tank is big enough for most homes without refilling.

Blue LED lights on the front illuminate debris that's invisible under normal lighting. This is genuinely useful on hard floors where dust and hair hide in plain sight.

Performance

TechRadar's testing was the strongest endorsement. They found the steam mode excelled at lifting dried grime and the hot water mode dissolved sticky kitchen spills with ease. The solid-liquid separation in the dirty water tank was impressive, and the heated self-cleaning process prevented odor.

Trusted Reviews was similarly positive: "Aside from the price, this is quite a perfect machine." They praised performance across hardwood, tile, vinyl plank, and laminate.

The counter-argument comes from Gadget Guy, who found the roller still felt cool to the touch during steam mode and saw "almost no difference between cleaning with or without steam mode, when compared to the hot water mode." This suggests the steam function is more useful for sanitizing than for cleaning power.

BGR noted that Roborock claims edge-to-edge cleaning up to 0.03 inches from the wall, but it still struggled with corners. You'll need a brush or cloth for tight corners and edges. This is a limitation shared with every wet-dry vacuum on the market, but it's worth knowing.

Build Quality & Design

The F25 Ultra is well-built. The handle feels solid, the power-assisted wheels work smoothly, and the self-cleaning dock is compact. Multiple reviewers mention it feels like a premium appliance.

The main design trade-off versus the Tineco S9 Artist is the display. The Tineco has a full 3D dynamic display on the handle. The Roborock's interface is simpler. This is a preference thing, not a quality issue.

Charge time is 4 hours for a full battery. That's slow. If you drain it during a big cleaning session, you're waiting half a day before you can use it again. The Tineco charges faster.

Value for Money

At full price, the F25 Ultra is the most expensive wet-dry vacuum from a major brand. It frequently goes on sale with significant discounts, and the sale price brings it closer to the Tineco S9 Artist.

Whether steam mode justifies the premium over hot-water-only competitors depends on how you use it. If you have young kids crawling on floors and want chemical-free sanitizing, steam adds real value. If you're mainly cleaning daily dirt and spills, hot water mode alone (available on cheaper machines) might be enough.

The Tineco Floor One S9 Artist costs less and has better battery life and a nicer display. The Dreame H15 Pro costs less and has a retractable squeegee for baseboard cleaning. Both lack steam. If steam sanitizing matters to you, the F25 Ultra is the only option.

Who Should Buy This

Homeowners with all hard floors (hardwood, tile, vinyl, laminate) who want the deepest possible clean. The steam and hot water combination handles everything from daily dust to dried-on messes.

Parents with babies and toddlers who crawl on floors. Chemical-free steam sanitizing at 356F gives peace of mind.

Anyone who has tried cheaper wet-dry vacs and been disappointed by odor, weak suction, or messy self-cleaning. The F25 Ultra's dock system and solid-liquid separation solve those problems.

Who Should Skip This

If you have carpet, this is a hard-floor-only machine. Look at a traditional vacuum instead.

If you need quick turnaround between cleaning sessions, the 4-hour charge time is a pain. The Tineco S9 Artist charges faster.

If corners and baseboards are your main frustration, no wet-dry vac handles them well. The Dreame H15 Pro's retractable squeegee does the best job, but even it has limits.
