The Big Three in Robot Vacuums
Three brands dominate the premium robot vacuum market: Roborock, Roomba (iRobot), and Ecovacs. Each brings distinct philosophies and technologies to automated floor cleaning. Choosing between them can feel overwhelming given their overlapping features and similar price points. This comprehensive showdown compares their flagship models head-to-head to help you make the right choice.
All three brands offer excellent cleaning performance, smart navigation, app control, and self-emptying options. The differences lie in their approach to mopping, obstacle avoidance, dock capabilities, and software features. By understanding these distinctions, you can match your needs to the best brand.
Brand Overview
Roborock
Roborock originated as a Xiaomi ecosystem company and has emerged as a leader in combined vacuum and mop robots. Their strength lies in offering premium features at more competitive prices than Western competitors. Known for excellent navigation, strong suction, and industry-leading mopping technology, Roborock appeals to value-conscious buyers who refuse to compromise on features.
Roomba (iRobot)
iRobot Roomba pioneered the robot vacuum category and remains the most recognized brand. Their focus is reliability, smart home integration, and obstacle intelligence. While often the most expensive option, Roombas offer the most mature ecosystem and widest support for home automation platforms. Their cleaning technology is pure vacuuming; separate Braava robots handle mopping.
Ecovacs
Ecovacs Deebot pushes innovation boundaries with features like built-in voice assistants, video monitoring, and the most comprehensive dock automation. Their newer models like the X2 Omni offer the highest suction power in the industry. Ecovacs targets buyers who want cutting-edge technology and are comfortable with a Chinese brand.

Navigation and Mapping
Roborock
Roborock uses LiDAR navigation combined with 3D structured light for obstacle detection. The mapping is fast and accurate, typically completing a home scan in under 10 minutes. Multi-floor maps are stored and automatically recognized. Room detection is generally accurate, and manual adjustments are easy in the app.
Roomba
The j7+ uses camera-based navigation (PrecisionVision) instead of LiDAR. This allows for obstacle identification – Roomba can recognize and avoid pet waste, cables, shoes, and other common hazards. The visual approach is slower for initial mapping but excels at not bumping into or spreading problematic objects. Maps can take multiple runs to complete fully.
Ecovacs
Ecovacs TrueDetect 3D technology combines LiDAR with a 3D structured light obstacle detection system. The X2’s square design allows it to clean corners more effectively than round competitors. Navigation speed and accuracy rival Roborock, with excellent obstacle avoidance that is not as camera-dependent as Roomba.
Cleaning Performance
Vacuuming
In pure suction power, Ecovacs leads with 8000 Pa, followed by Roborock at 6000 Pa. Roomba does not publish Pa ratings but is estimated around 2500 Pa with its dual rubber extractors focusing on agitation rather than raw suction. In practice, all three handle typical household debris effectively on both carpet and hard floors. Pet hair performance is comparable across all models.
Mopping
Roborock and Ecovacs integrate mopping with their vacuum robots. Roborock’s VibraRise 2.0 uses sonic vibration up to 4000 times per minute with auto-lifting when carpets are detected. Ecovacs OZMO Turbo 2.0 uses dual rotating mop pads with more aggressive scrubbing action. Both wash and dry their mops automatically in their docks.
Roomba does not mop. iRobot separates floor care into Roomba (vacuum) and Braava (mop) robots that can work in coordination but are separate purchases.
Dock Capabilities
Roborock RockDock Ultra: Empties dustbin, washes and dries mops with hot air, refills water tank. Requires occasional empty of dirty water and refill of clean water. Compact footprint for its functionality.
Roomba Clean Base: Empties dustbin only. Uses disposable bags that hold up to 60 days of debris. No mop support since Roomba does not mop. The simplest dock with the smallest footprint.
Ecovacs OMNI Station: Everything Roborock offers plus hot water mop washing (55 degrees Celsius) for better sanitization. The most comprehensive dock but also the largest physically.
Smart Home Integration
Roomba wins for smart home integration with the deepest Alexa and Google Home support, plus IFTTT capabilities that competitors lack. You can create complex automations based on cleaning events. See our smart vacuum guide for detailed integration tips.
Roborock and Ecovacs offer solid basic voice control through Alexa and Google, but fewer advanced automation triggers. Ecovacs adds built-in YIKO voice assistant on the robot itself, useful in rooms without smart speakers.
Which Should You Choose?
Choose Roborock If:
- You want the best balance of features and price
- You need both vacuuming and mopping in one device
- Reliable LiDAR navigation matters to you
- You prefer a mid-size premium dock footprint
Choose Roomba If:
- Smart home integration is a priority
- You have pets and worry about “accidents”
- You do not need mopping or prefer separate devices
- Brand reliability and support matter most
- You want the most compact dock
Choose Ecovacs If:
- Maximum suction power is important
- You want the most advanced mopping with hot water
- Built-in voice assistant appeals to you
- You want cutting-edge features first
- Budget is not a primary concern
Frequently Asked Questions
Can robot vacuums replace regular vacuuming?
For daily maintenance, yes. For periodic deep cleaning of carpets, many households still prefer occasional manual vacuuming with an upright or canister. Robot vacuums excel at keeping floors clean between deep cleans rather than replacing them entirely.
Are these robots good for pet hair?
All three brands handle pet hair well. Roomba’s rubber extractors resist tangling, while Roborock and Ecovacs use brush rolls with anti-tangle features. Self-emptying bases are particularly valuable for pet owners as they contain allergens.
Conclusion
All three brands deliver excellent robot vacuuming. Roborock offers the best value with premium features at competitive prices. Roomba provides the most mature platform with superior smart home integration. Ecovacs pushes boundaries with the most powerful specs and innovative features.
