If you are looking to buy a premium robot vacuum, your research has likely narrowed down to two names: iRobot Roomba and Roborock.
They are the Apple and Samsung of the cleaning world. Roomba (the American pioneer) dominated the market for 20 years. But recently, Roborock (the tech-heavy challenger) has taken the world by storm with advanced laser navigation and superior mopping. So, which one deserves your hard-earned money in 2025? In this detailed showdown, we compare their flagship technologies to help you decide.
The Core Difference: Navigation (Camera vs. Laser)
This is the most critical difference between the two brands.
1. Roborock (LiDAR Navigation)
Almost all Roborock models use LDS LiDAR. It looks like a spinning turret on top of the robot.
Pros:
- Creates a map instantly (in seconds).
- Works perfectly in pitch-black darkness.
- extremely precise movement (doesn't bump into furniture).
2. Roomba (vSLAM Camera)
Most Roombas (like the j7 and s9) use a Camera to "see" landmarks on your ceiling and walls.
Pros: Lower profile (no turret on top), so it fits under lower sofas.
Cons: Can struggle in low light. Mapping takes a few "learning runs" to complete.
Cleaning Performance: Carpets vs. Hard Floors
For Carpets: Roomba Wins
Roomba holds a patent that gives it a massive advantage: Dual Multi-Surface Rubber Brushes.
Instead of one brush, Roombas have two rollers spinning in opposite directions. They grab the carpet fibers and pull dirt out deeply. They are also amazing at resisting hair tangles.
Roborock typically uses a single brush, which is good, but not "Roomba good" on deep carpets.
For Mopping: Roborock Wins
Roomba generally separates vacuuming and mopping into two different robots (Roomba for vacuuming, Braava for mopping).
Roborock excels at Hybrids (2-in-1). Their "VibraRise" technology scrubs the floor 3,000 times a minute and automatically lifts the wet cloth when it detects carpet. It’s a seamless experience.
Obstacle Avoidance (The "Poop" Test)
Both brands now feature AI cameras to detect obstacles like cables, socks, and pet waste.
- Roomba (P.O.O.P Pledge): iRobot is so confident in their AI (on the j7/j9 series) that they promise to replace the robot for free if it runs over pet poop. Their database of images is massive.
- Roborock (ReactiveAI): Very good, but slightly more aggressive. It might get closer to the obstacle than the Roomba.

FAQ: Which One Fits Your Home?
I have 90% carpet and a Golden Retriever. Which one?
Get a Roomba (j7+ or s9+). The dual brushes are unmatched for digging hair out of carpet fibers without getting tangled.
I have hardwood floors and hate mopping. Which one?
Get a Roborock (S7 or S8 series). The sonic mopping feature will scrub dried stains off your floor effectively.
Which one lasts longer?
Roomba has a reputation for durability and easily available spare parts (since they are a US company). Roborock is reliable, but getting specific parts can sometimes be harder depending on your region.
Choose Roomba if you want a "set it and forget it" simple experience focused on carpets.
Choose Roborock if you want the smartest tech, the best map, and a robot that can mop and vacuum simultaneously.
