Quick Verdict
Summary
E35 is the roller-mop choice; Saros 20 is the access-and-carpet-routine choice. Neither is a proven overall cleaning winner in matched SRR testing.
Choose Eufy Omni E35
Start here for frequent hard-floor washing when you prefer a roller and do not need a particularly low robot. Its verified US offer was lower at our latest check.
Choose Roborock Saros 20
Investigate its slim profile, adaptive chassis and automatic mop detachment when furniture and mixed flooring complicate your cleaning route.
In short
Shortlist E35 first when roller mopping is the feature you want and your layout is uncomplicated. Investigate standard Saros 20 first when low furniture, transitions or mop-free vacuuming runs are the stronger buying reasons. Neither has earned an overall cleaning win over the other without matched tests.

E35 is the choice to investigate if you prefer roller washing. We do not have matched cleaning tests proving that either removes stains better.
Can Saros 20 leave its mops behind?

Which should I buy for pets?
Consider floor type, rug layout and maintenance access. Both have detangling brush designs, but comparable pet-hair tests are unavailable here.
