Cordless Vacuums / Roborock
Roborock F25 Ultra
The only washer here that self-cleans with genuinely hot water and steam.
Overall score 6.9/10
Pros
- + The self-clean actually uses heat — 194°F water and 356°F steam on the roller, then 203°F drying — where Tineco's and Bissell's use cold tank water
- + 356°F steam lifts dried-on grease that a plain wet roller simply smears around
- + The detachable separation module means emptying the dirty tank does not put your fingers into hair slurry
- + 22,000 Pa, 180° lay-flat and an auto detergent dispenser you refill roughly monthly
Cons
- − 12.1 lb is the heaviest machine on this page and you feel it before the tank is empty
- − Roborock publishes no runtime for the steam or hot-water modes, which are the modes that justify the price
- − Only a 1-year warranty against Shark's 5 and Miele's 2
- − No air-watt figure, no HEPA claim, and on carpet it is no substitute for a dry stick vacuum
Roborock F25 Ultra review: what the specs say
The only washer here that self-cleans with genuinely hot water and steam. At $599.99, Roborock's 2025 model sits in the middle of the range — the cordless Vacuums we compare run from $129.99 to $1,199. It scores 6.9/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Maintenance & Emptying at 9.5/10 — bin or tank emptying, whether your hand ends up near the dust, self-clean quality and the ongoing cost of filters, bags and detergent. The weakest is Battery System at 4.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: 12.1 lb is the heaviest machine on this page and you feel it before the tank is empty; and roborock publishes no runtime for the steam or hot-water modes, which are the modes that justify the price. Every specification on this page comes from Roborock's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| Machine Type | Cordless wet-dry hard-floor washer with steam |
| Suction (as published) | 22,000 Pa. Roborock publishes Pa only — there is no air-watt figure, so it is not comparable with the dry sticks |
| Runtime, Eco / Headline | 60 min |
| Runtime, Max Power | Not published by the manufacturer. VacuumWars measured roughly 15-25 minutes in the steam and hot-water modes against up to 60 in Auto min |
| What the Runtime Claim Actually Means | Auto mode is up to 60 minutes. Heating water to 187°F or generating 356°F steam is what actually drains the pack, and Roborock publishes no figure for either — the heated modes are the ones people buy this for |
| Removable Battery | Not published by the manufacturer — Roborock does not describe the pack as user-removable |
| Spare Battery | Not published by the manufacturer |
| Dock / Wall Mount | Self-cleaning charging dock included |
| Filtration | Washable filters on the dirty-water separation module. Roborock makes no HEPA claim and no sealed-system claim |
| Bin / Tank Capacity | 1.0 L clean water tank; dirty-water tank with a detachable solid/liquid separation module |
| Weight | 12.1 lbs |
| Filters, Consumables & Self-Clean | The only washer here whose self-clean genuinely uses heat: 194°F water and 356°F steam on the roller, then about 5 minutes of 203°F hot-air drying, with anti-scale protection Roborock rates for three years. The dirty tank is still emptied by hand, but the separation module strains the hair out first so your hand stays clear of the slurry. Detergent auto-dispenses from Roborock's own solution; third-party compatibility is not published |
| Connectivity | Roborock app, Wi-Fi, Display on the handle |
| Material | Plastic with stainless accents |
| Warranty | 12 months |
