Both robots sit in the same fully self-maintaining tier: automatic dirt
emptying, automatic mop washing, automatic mop lifting, and automatic water
tank refilling from the dock are standard on each. Where they pull apart is
raw hardware. The T90 Pro Omni pulls 30,000 Pa of suction against the
Curv 2 Flow’s 20,000 Pa, runs quieter at 60 dBA versus
63 dBA, and sits lower at 9.5 cm versus 11.9 cm, which helps
it reach under more furniture. It also clears higher thresholds,
24 mm versus 20 mm, and covers more ground per charge,
350 minutes of runtime against 242, despite carrying a smaller
4,000 mAh battery. It recharges faster too: 150 minutes versus
180.
The Curv 2 Flow answers on a different front. It carries a
HEPA-certified filter, something the T90 Pro Omni skips entirely, and
navigates with spinning LiDAR and a camera rather than the T90’s
ToF-and-structured-light setup. It also runs two side brushes instead of
one and holds a slightly larger 324 ml dustbin against the
T90’s 250 ml. If raw cleaning power, a lower profile, and
longer runtime matter most, the T90 Pro Omni has the stronger numbers
across the board. If HEPA-grade filtration for allergies or pets matters
more, the Curv 2 Flow is the one that offers it.
