Side-by-Side Comparison
| Spec | Roborock F25 Ultra | Tineco FLOOR ONE S7 Stretch Ultra |
|---|---|---|
| Price | $599.99 | $449.00 |
| Release Year | 2025 | 2025 |
| Machine Type | Cordless wet-dry hard-floor washer with steam | Cordless wet-dry hard-floor washer — it vacuums and washes sealed hard floors, and is not a carpet vacuum |
| 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 | 21 kPa sealed suction with a 230 W motor rating. Tineco publishes no air-watt figure, so this cannot be compared directly with the dry sticks here |
| Runtime, Eco / Headline (min) | 60✓ | 50 |
| Runtime, Max Power (min) | Not published by the manufacturer. VacuumWars measured roughly 15-25 minutes in the steam and hot-water modes against up to 60 in Auto | Not published by the manufacturer — Tineco quotes 50 minutes and does not break it down by Auto, Max or Suction mode |
| 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 | Unlike a dry stick there is no non-powered-tool inflation here: the roller motor always runs on a washer, so the 50 minutes is the machine as sold. Tineco still publishes no Max-mode figure |
| Removable Battery | Not published by the manufacturer — Roborock does not describe the pack as user-removable | No — the 7-cell 3,900 mAh pack is internal and not user-swappable |
| Spare Battery | Not published by the manufacturer | Not applicable — the battery is not user-replaceable |
| Dock / Wall Mount | Self-cleaning charging dock included | Charging and self-clean dock included; the machine runs its self-clean cycle sitting in the dock |
| Filtration | Washable filters on the dirty-water separation module. Roborock makes no HEPA claim and no sealed-system claim | A washable dry filter sits over the dirty-water tank. Tineco makes no HEPA claim and no sealed-system claim for this model |
| Bin / Tank Capacity | 1.0 L clean water tank; dirty-water tank with a detachable solid/liquid separation module | 1.0 L clean water tank and a 0.72 L dirty water tank |
| Weight (lbs) | 12.1 | Not published by the manufacturer for the Stretch Ultra (the older S7 Pro is 11.46 lb) |
| 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 | The FlashDry self-clean washes the roller with unheated tank water and then dries it with 185°F (85°C) air for 5 minutes — the 185°F in the marketing is the drying air, not the wash water. Hot-water washing needs the S7 Stretch Steam instead. The dirty-water tank and its hair filter are still emptied and rinsed by hand every time. Tineco specifies one capful of its own solution per tank and advises against third-party detergents |
| Warranty | 12 months | 24 months |

Category Scores
Suction Power
The Roborock F25 Ultra leads clearly here, 8.0 against 6.5 — a 1.5-point margin on actual cleaning force at the head, judged on air watts where a maker publishes them and discounted where only Pa or motor watts are quoted.

Sustained Runtime
The Tineco FLOOR ONE S7 Stretch Ultra leads clearly here, 7.0 against 6.0 — a 1.0-point margin on how long the machine really runs on max power with the motorised floor head attached — not the eco-mode, bare-tool figure on the box. If that is what you are buying for, the Roborock F25 Ultra does not close the gap elsewhere.
Filtration & Sealing
The Roborock F25 Ultra leads clearly here, 5.5 against 5.0 — a 0.5-point margin on whether the whole machine is sealed or a HEPA element simply sits inside a leaky body, and what the claimed rating is actually measured at. If that is what you are buying for, the Tineco FLOOR ONE S7 Stretch Ultra does not close the gap elsewhere.
Handling & Ergonomics
The Tineco FLOOR ONE S7 Stretch Ultra leads clearly here, 8.0 against 6.5 — a 1.5-point margin on weight, balance, whether power is a push-button or a trigger you must hold, and how it stores. If that is what you are buying for, the Roborock F25 Ultra does not close the gap elsewhere.
Maintenance & Emptying
The Roborock F25 Ultra leads clearly here, 9.5 against 7.5 — a 2.0-point margin on bin or tank emptying, whether your hand ends up near the dust, self-clean quality and the ongoing cost of filters, bags and detergent. If that is what you are buying for, the Tineco FLOOR ONE S7 Stretch Ultra does not close the gap elsewhere.
Battery System
The Roborock F25 Ultra and Tineco FLOOR ONE S7 Stretch Ultra are level here, at 4.0/10 each. removable or sealed, how many packs are included, what a spare costs and whether the pack is shared across a range is not what separates these two — look to the categories where the scores diverge.
Versatility
The Roborock F25 Ultra leads clearly here, 7.5 against 6.5 — a 1.0-point margin on handheld conversion, above-floor tools, carpet capability and wet-mopping ability. If that is what you are buying for, the Tineco FLOOR ONE S7 Stretch Ultra does not close the gap elsewhere.
Value
The Roborock F25 Ultra leads clearly here, 8.0 against 7.5 — a 0.5-point margin on what you actually get for the street price once consumables and missing accessories are counted. If that is what you are buying for, the Tineco FLOOR ONE S7 Stretch Ultra does not close the gap elsewhere.

Pros & Cons
Roborock F25 Ultra
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
Tineco FLOOR ONE S7 Stretch Ultra
Pros
- +Lays flat to 5.1 inches and goes under furniture — the single reason to pick this over the older S7 Pro
- +Hot-air drying after every self-clean is what stops the roller going sour between uses
- +Dual-sided edge cleaning reaches within about a centimetre of a baseboard on both sides
- +The iLoop sensor throttles suction and water to the actual dirt, which is why 50 minutes is a realistic working figure
Cons
- −The self-clean washes with unheated tank water; only the drying air is 185°F. Hot-water washing costs $150 more on the Stretch Steam
- −The battery is sealed inside — when the pack dies, the machine dies
- −Tineco advises against third-party solution, so detergent is a permanent tie to Tineco
- −You still empty and rinse the dirty-water tank and pick the hair out of its filter by hand after every use
