Side by side

Which to pick

• High door sills or a low sofa: the Roborock Saros 20 is rated for sills up to 1.77 in and stands 3.14 in tall.
• A full dock for less: the Roborock QV 35A ($449.99) empties its bin, washes its mops and refills its tank; the ECOVACS DEEBOT N30 PRO OMNI ($315.00) also washes its mops in 140°F water.
• A roller mop: the ECOVACS DEEBOT X9 PRO OMNI and ECOVACS DEEBOT X11 OmniCyclone use a roller washed in water up to 167°F.
• You want to know how loud it is: ECOVACS publishes a cleaning-noise figure for every model here; Roborock doesn’t for these two. See the quietest robot vacuums.

Every model here was on sale in the US before the FCC rule of July 28, 2026, and models authorized before that date can still be sold.
