The catch
eufy Omni E28
In independent testing, pet-hair pickup was merely average and long hair bunched up.
Side by side
E28 is the pick if you will use its portable spot cleaner on upholstery. X9 PRO OMNI is easier to fit beneath low furniture and into a narrow dock space.
Before you buy
eufy Omni E28 is 111.76 mm tall and ECOVACS DEEBOT X9 PRO OMNI is 98 mm. ECOVACS DEEBOT X9 PRO OMNI sits 13.8 mm lower, and it still needs clearance above the chassis.
Where this comes from
Absolute height difference = |111.76 - 98| = 13.8 mm. The comparison uses published minimum chassis heights and does not guarantee safe gap sizes.
The catch
In independent testing, pet-hair pickup was merely average and long hair bunched up.
The catch
Compared with T50 Pro, the 98 mm body needs more headroom. The roller also means extra parts to rinse and inspect.

The spot cleaner is what E28 really adds
Which one fits
The detachable cleaner takes on jobs the robot cannot reach, such as suitable upholstery. Plan to use it. Otherwise it is an accessory that adds bulk and sits unused.
E28 stands about 111.8 mm tall and X9 stands 98 mm, a difference that can decide a bed or cabinet even when E28 comes with a broader cleaning kit.
E28 is about 371.6 mm wide by 484.4 mm deep, and X9 is 338 by 459 mm. Either one needs extra room to approach and to remove tanks.
Not counting access space, the outer area of the E28 station is about 16% greater than X9.
