Roborock Qrevo S vs Ecovacs Deebot X9 Pro Omni
Quick take: The Roborock Qrevo S costs $350 less; the Ecovacs Deebot X9 Pro Omni has stronger suction (16,600 vs 7,000 Pa); the Ecovacs Deebot X9 Pro Omni runs longer per charge (252 vs 180 min).
Which one to buy
The Roborock Qrevo S has been discontinued, with the Qrevo S Pro at $700 as its successor, so at $450 against the Ecovacs Deebot X9 Pro Omni's $800 you're choosing between leftover stock of a proven budget robot and a current flagship with a rougher start. On paper the Ecovacs is far ahead: 16600 Pa against 7000 Pa, a camera for obstacle avoidance, hot-water mop washing, and a 2-year warranty against the Qrevo S's 1 year.
X9 owners mostly back that up once it's running. They praise how much debris and pet hair it pulls from carpet, a brush roll they no longer have to untangle, and a roller mop that leaves most floors streak-free. The problem is getting there. Mapping is the most serious complaint, with owners describing five or more remaps and many hours before room recognition works, and mirrors or glass confuse it further. Some see soapy lines or water droplets after mopping, thin rugs without rubber backing trip it up, and a few find it docking after two rooms on stronger settings.
Qrevo S owners describe the opposite profile: reliable from day one, great mopping, pads that lift over carpet, and weeks of hands-free running. Its weaknesses are the ones its specs suggest. Without a camera it eats cables, carpet cleaning is weak, long pet hair can jam the intake, and its dock washes pads in unheated water.
For carpet, pets, or a cluttered floor, the X9 is the stronger machine and the one still on sale, as long as you have patience for setup. The Qrevo S only makes sense for a tidy, mostly hard-floor home that values a robot that works without fuss, and with it discontinued, that case gets weaker as stock runs out.
Roborock Qrevo S
Suits a tidy, mostly hard-floor home that wants dependable mopping with no setup headaches, as long as you're comfortable buying a discontinued model.
Ecovacs Deebot X9 Pro Omni
For carpet, pet hair or a cluttered floor, it's the stronger and current robot with a camera, hot-water washing and a 2-year warranty, if you can sit through a slow mapping setup.

Roborock Qrevo S vs Ecovacs Deebot X9 Pro Omni: common questions
Is the Ecovacs Deebot X9 Pro Omni harder to set up than the Roborock Qrevo S?▾
By owner accounts, much harder. X9 owners report five or more remapping attempts and many hours before rooms are recognized reliably, with mirrors and glass making it worse. Qrevo S owners describe it as reliable from the start, using Roborock's mature app.
Which is better on carpet and pet hair, the Qrevo S or the Deebot X9 Pro Omni?▾
The X9 Pro Omni. Its owners praise carpet pickup and say the brush roll no longer needs untangling. Qrevo S owners call it weak on carpet, especially patterned carpet, and report long pet hair jamming the intake in heavy-shedding homes.
Does it matter that the Roborock Qrevo S is discontinued?▾
Yes. At $450 against $800 the Qrevo S is $350 cheaper, but it is a retired model with a 1-year warranty against a current one with 2 years, and Roborock's successor, the Qrevo S Pro, costs $700. The Qrevo S still earns its place in a tidy hard-floor home if you find leftover stock.
