What reviewers found
Ecovacs Deebot X9 Pro Omni
- Vacuum Wars: Measured 2.76 kPa suction and 27 CFM airflow, 93% pet hair pickup, 0% hair wrap, 158 of 184 on dried stains and 89% carpet deep clean. Coverage was 876 sq ft per charge against a 1,015 sq ft average. Source
- MacRumors: Three months of testing. Long hair did not tangle the brush, mopping and navigation beat the X8 Pro Omni, and Siri control through Matter worked. Thin rugs caused frequent tangles and vacuuming was loud. About 1,000 sq ft per charge. Source
Yeedi S20 Infinity Ultra
- Homes & Gardens (4.5 out of 5): Measured about 56 dB. Picked up rice right away but needed extra passes for sugar. Mopped ketchup, mustard and soy sauce in one pass and avoided a thick HDMI cable, but kept about six inches from larger objects. Source
- CGMagazine (9.5/10): FocusJet nearly removed a two hour old oil and soy sauce stain and fine dust came up in one pass. Louder than the Yeedi M14 Plus. No lab measurements. Source
