Cordless Vacuums / Tineco
Tineco FLOOR ONE S7 Stretch Ultra
Lays flat under furniture and dries itself hot — but self-cleans with cold water.
Overall score 6.5/10
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
Tineco FLOOR ONE S7 Stretch Ultra review: what the specs say
Lays flat under furniture and dries itself hot — but self-cleans with cold water. At $449, Tineco's 2025 model sits in the middle of the range — the cordless Vacuums we compare run from $129.99 to $1,199. It scores 6.5/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Handling & Ergonomics at 8.0/10 — weight, balance, whether power is a push-button or a trigger you must hold, and how it stores. 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: 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; and the battery is sealed inside — when the pack dies, the machine dies. Every specification on this page comes from Tineco'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 — it vacuums and washes sealed hard floors, and is not a carpet vacuum |
| Suction (as published) | 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 | 50 min |
| Runtime, Max Power | Not published by the manufacturer — Tineco quotes 50 minutes and does not break it down by Auto, Max or Suction mode min |
| What the Runtime Claim Actually Means | 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 | No — the 7-cell 3,900 mAh pack is internal and not user-swappable |
| Spare Battery | Not applicable — the battery is not user-replaceable |
| Dock / Wall Mount | Charging and self-clean dock included; the machine runs its self-clean cycle sitting in the dock |
| Filtration | 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 and a 0.72 L dirty water tank |
| Weight | Not published by the manufacturer for the Stretch Ultra (the older S7 Pro is 11.46 lb) lbs |
| Filters, Consumables & Self-Clean | 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 |
| Connectivity | Tineco app, Wi-Fi, LED display on the handle |
| Material | ABS plastic with translucent tanks |
| Warranty | 24 months |
