(checked 2026-10-10)The listing pools many F25 variants (BX, LT, XT, ACE, Steam, GT and others).
Amazon's most-rated pick here, with nearly 5,000 ratings and a low 11% low-star share. Wirecutter calls it a cheaper alternative to its upgrade pick that lays flat and cleans well in auto mode. But Wirecutter found one of the worst debris separators it tested, and Vacuum Wars found the Ultra version heavy, with below-average suction.
Top complaints
- Poor debris separation
Wirecutter says its dirty-water tank has one of the worst debris separators it tested, so you'll be sorting through a slurry after cleaning, and the clean-tank setup is less elegant than its upgrade pick's.
Source: Wirecutter - Heavy, below-average suction (Ultra)
Vacuum Wars measured the F25 Ultra at 5,506 g (about 12.1 lb) with usable suction of 1.05 kPa against a 1.17 kPa average, and says runtime drops to about 15-25 minutes in steam or hot-water modes.
Source: Vacuum Wars review (F25 Ultra) - Mixed durability and streaking
Amazon's review summary says durability is mixed, with some owners reporting it broke within a year; streak-free results and value for money are also mixed.
What owners love
- Cleans combination and dried messes
Wirecutter says it ably picks up combination and dried messes in auto mode. Vacuum Wars gave the Ultra a mopping score of 151.5 (115 average). Amazon owners say it picks up dirt and hair effectively.
- Self-cleaning and quick drying
Wirecutter calls the self-clean cycle good. Amazon owners call the self-cleaning and quick drying amazing, and Vacuum Wars notes about five minutes of hot-air roller drying on the Ultra.
- Lays flat, easy to use
Wirecutter says it cleans while lying flat; Vacuum Wars measured 4.9 inches of under-furniture reach on the Ultra. Amazon owners find it easy to use, with little reassembly.

What experts say
- Wirecutter (NYT): Other good option (guide updated 2025-07-31): high-end features for about $100 less than its Narwal upgrade pick, but one of the worst debris separators tested.
- Vacuum Wars: The F25 Ultra ranks #5 on its hard-floor list (updated 2026-10-07): strong mopping, low residue, 60 minutes in auto mode and a 1-liter tank. Cons: 12.1 lb and below-average suction. List $799.99.
