What the differences mean

Suction power

The Roborock Saros 20 Sonic is rated at 36,000 Pa, close to double the 19,000 Pa of the MOVA E40 Ultra. On carpet and against heavy pet hair the Roborock pulls embedded debris out with less effort, while the MOVA E40 Ultra leans on its top mode more often.

Warranty

The MOVA E40 Ultra carries a three-year warranty where the Roborock Saros 20 Sonic offers one. For a machine that runs daily on the floor, that is the clearest practical advantage of the MOVA E40 Ultra.

Battery life

The MOVA E40 Ultra is rated for 260 minutes and the Roborock Saros 20 Sonic for 190, both returning to the dock to top up and resume. On a large floor the MOVA E40 Ultra finishes in one pass more often.

Water and dust capacity

The MOVA E40 Ultra lists a 4.5 L clean water tank and a 3.2 L dust bag rated for up to 75 days, against a 4 L tank and a 2.7 L bin for the Roborock Saros 20 Sonic. The MOVA E40 Ultra goes longer between refills and emptyings.

Smart home support

Matter brings the Roborock Saros 20 Sonic into Apple Home, SmartThings and Home Assistant on top of Alexa and Google Home. The MOVA E40 Ultra supports Alexa, Google Home and a community Home Assistant integration, with no Matter, Apple Home or SmartThings.

Body height

The Roborock Saros 20 Sonic is 79.8 mm tall and reaches under low furniture, while the MOVA E40 Ultra does not publish its dimensions. In a home with low sofas, the Roborock is the one with a stated height.

What owners say

MOVA E40 Ultra owners describe an easy, quiet robot: several report it mapping a large home in about fifteen minutes and getting straight to work, and multi-dog households praise the pet-hair pickup at its price. The station habit of returning to wash the pads, empty the bin and refill during a job is what convinces owners it is worth the money, and the extendable mop reaching corners gets repeated mention. Support earns mixed reviews, with some owners receiving a replacement without argument. The complaints cluster on mop pads detaching mid-run, early side-brush and motor failures, and slow escalation when something goes wrong.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
