Ecovacs T90 Pro Omni
7 sources3 derived$4,999as of Sep 19

The Ecovacs T90 Pro Omni stands out in the robot vacuum market with its advanced Osmo Roller 3.0 mopping system that actively scrubs floors with fresh water while self-cleaning during operation. TechRadar called it one of the most capable high-value models tested, particularly praising its effectiveness on sticky spills and stained areas. The device excels in mixed flooring environments and is well-suited for homes with kids and pets. However, reviewers noted that its mopping process may take longer than conventional pad-based systems and requires regular maintenance of cleaning solution. This makes it ideal for users seeking premium cleaning performance but may not suit those prioritizing speed over thoroughness.

Strengths
  • Uses Osmo Roller 3.0 system with 27 cm rotating microfiber roller for active scrubbing
  • Fresh Flow power washing system provides clean water during mopping and self-washes roller at 200 RPM
  • Effective stain removal on tough areas like kitchens and dining spaces
Watch-outs
  • Mopping performance may be slower than traditional pad-based robots
  • Navigation and battery efficiency issues
Roborock Saros 20
Ranked #4 in Best Robot Vacuums
Roborock Saros 20
8 sources$1,599.99as of Sep 19

The Roborock Saros 20 delivers strong performance in both vacuuming and mopping, with powerful suction and effective cleaning technology. It features a self-cleaning dock and quiet operation, but comes at a steep price point and has a bulky base station that's difficult to relocate. The device is well-suited for users seeking premium cleaning capabilities but may be overkill for those with simpler needs or budget constraints.

Strengths
  • Powerful suction with 36,000 pascals of official suction rating
  • Effective mopping with dual mop pad design spinning at 200 RPM
  • Self-cleaning dock with boiling hot water mopping and automatic drying
Watch-outs
  • Heavy base station that is difficult to move between floors
  • High price point

How they stack up

Ecovacs T90 Pro Omni

The Ecovacs T90 Pro Omni's Osmo Roller 3.0 system is more advanced than the basic pad mopping of the Roborock Saros 20 or the Eufy Omni C28, but it's slower than the latter's mopping and lacks the suction power of the Roborock Q10 S5+.

Roborock Saros 20

The Roborock Saros 20 stands out with its powerful 36,000 pascals suction and self-cleaning dock with boiling hot water mopping, which the Dreame D30 Ultra and Shark PowerDetect UV Reveal lack. However, unlike the Roborock Saros 10R, it doesn't offer the ultra-slim design or advanced 3D navigation, and its heavy base station is a drawback compared to more portable models like the Roomba J7.
