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.
Full review
Vacuuming performance exceeds expectations
The vacuuming performance of the T90 Pro Omni delivers on its promise of powerful suction, In testing, it consistently outperformed average models in carpet deep-cleaning tasks, with reviewers noting particularly strong results in pet hair removal. The ZeroTangle 4.0 brush system demonstrated its effectiveness by scoring perfectly in seven-inch hair tangle tests, a feat that sets it apart from many competitors. The combination of Blast technology and advanced roller design ensures that even stubborn dirt and fine particles are effectively captured, making it a standout choice for households with pets or heavy foot traffic.
Mopping system represents a major upgrade
The Osmo Roller 3.0 mopping system delivers a significant leap in performance compared to previous generations, featuring a 27-centimeter microfiber roller that provides superior surface coverage. This system operates with continuous self-washing during cleaning cycles, preventing cross-contamination and reducing streaking issues common in other robotic mops. The ability to extend and lift the mop roller for carpet cleaning adds versatility, while the automatic water management system ensures consistent cleaning quality throughout extended use.
Navigation and obstacle avoidance show mixed results
While the T90 Pro Omni features advanced navigation technology including embedded Mini-ToF Lidar and AI camera systems, real-world performance revealed some inconsistencies. Reviewers noted that despite its sophisticated obstacle detection capabilities, the robot occasionally struggled with door thresholds, particularly those measuring 2-3 centimeters high. The robot's ability to navigate around obstacles was rated as slightly above average, though it still required frequent returns to the charging station for battery top-ups, indicating room for improvement in battery efficiency and navigation optimization.
Charging and battery efficiency concerns
The robot's 4,000 mAh battery provides approximately 1.6 hours of operation, sufficient for cleaning areas up to 500 square meters in a single session. However, testing revealed that the device needed to return to its base more frequently than expected, particularly in larger homes or during extended cleaning cycles. The charging process, while fast, did not entirely eliminate the need for regular recharging, and reviewers noted that the battery efficiency could be improved to better support longer cleaning sessions without interruption.
Dock design and maintenance automation
The OMNI station represents a significant advancement in automated maintenance, featuring self-washing, self-drying, and water management capabilities for the mop roller. The dock includes clean and dirty water tanks positioned side by side, with clear visual indicators for water status. The station's design prevents leaks and offers convenient access for refilling cleaning solutions, with a 2.5-liter dust bag capable of holding up to 90 days' worth of debris. The inclusion of hot-water mop washing and heated air drying further enhances cleaning effectiveness. However, some reviewers noted that the small 250ml dustbin required more frequent emptying, though the auto-emptying feature helped mitigate this issue in regular use.
User experience and app functionality
The Ecovacs Home app provides comprehensive control over the T90 Pro Omni's cleaning schedules, virtual barriers, and mapping capabilities. Users can monitor cleaning progress through live video feeds and receive notifications about maintenance requirements. The integration with Matter protocol allows for seamless smart home compatibility, while the voice assistant functionality supports basic commands within a five-meter radius. Despite these features, some reviewers found the app's interface could be more intuitive, particularly when setting up new cleaning zones or configuring advanced features. The lack of a pure mopping mode was also noted as a limitation for users who prefer dedicated wet cleaning without suction.
Size and design considerations
The robot's 40mm threshold crossing capability allows it to navigate over small obstacles, though performance varied depending on the specific height and surface texture. The front cover of the base is easily removable for maintenance, and the included 260ml detergent bottle provides sufficient cleaning solution for extended use. The side brush, while not extendable, features long bristles that reach far and effectively collect debris. The overall build quality and aesthetic design align with Ecovacs' premium positioning, though some reviewers noted that the device's size and weight distribution could affect its stability on certain surfaces.
Price and value proposition
At a price point of $899.99, the T90 Pro Omni positions itself as a premium mid-range option that delivers flagship-level features at a more accessible cost. Reviewers generally found the value proposition compelling given the combination of powerful suction, advanced mopping technology, and automated maintenance capabilities. The inclusion of features like PowerBoost charging, Matter compatibility, and the self-cleaning dock justifies the premium price for users seeking comprehensive floor cleaning automation. However, some reviewers suggested that the device's performance in navigation and battery efficiency could be improved to better match its price point and feature set, particularly for users with larger homes or more complex cleaning requirements.
Strengths

Watch-outs
- −Mopping performance may be slower than traditional pad-based robots
- −Navigation and battery efficiency issues
How it compares
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+.
