Robot Vacuums Ranked: Which One Actually Cleans Properly
Smart Home
By Marwin Jaino Cervañez

Robot vacuums have come a long way from being glorified dust pushers. The latest models promise intelligent navigation, self-emptying docks, object avoidance, and enough suction power to replace your regular vacuum. But when it comes to actual cleaning performance, not every robot vacuum delivers on the marketing hype.
For this comparison, we're focusing on what matters most: how well these machines pick up dirt, pet hair, dust, and debris in real-world homes. Features are nice, but if a robot vacuum can't clean properly, nothing else matters.
The Contenders
Here are the three of the most talked-about robot vacuums in 2025:
Roborock S8 MaxV Ultra
iRobot Roomba Combo j9+
Ecovacs Deebot X8 Pro Omni
These models represent the premium end of the market, where buyers expect genuine hands-free cleaning.
Cleaning Performance Rankings
1. Roborock S8 MaxV Ultra

If cleaning performance is the only metric, the Roborock S8 MaxV Ultra currently sits at the top of the robot vacuum food chain.
The combination of powerful suction, dual rubber brushes, and advanced navigation allows it to tackle everything from fine dust to larger debris without getting stuck. It performs particularly well on carpets, where many robot vacuums still struggle.
The edge-cleaning system is also one of the best available. Corners remain a challenge for all robot vacuums, but the S8 MaxV Ultra gets noticeably closer than most competitors.
What It Does Best
Excellent carpet cleaning
Outstanding pet hair pickup
Reliable obstacle avoidance
Consistent room coverage
Where It Falls Short
Premium price tag ($1,899.99)
Dock system takes up significant space
Maintenance costs are higher than average
2. Ecovacs Deebot X8 Pro Omni

The Ecovacs Deebot X8 Pro Omni comes surprisingly close to Roborock in raw cleaning ability.
On hard floors, the difference is almost impossible to notice. Dust, crumbs, pet hair, and everyday debris are collected efficiently, and the advanced mopping system performs particularly well on dried stains.
Where the Ecovacs loses points is consistency. Occasionally it misses small areas during cleaning cycles, especially in cluttered rooms.
What It Does Best
Excellent hard-floor cleaning
Strong mopping performance
Feature-rich docking station
Competitive suction power
Where It Falls Short
Navigation can be slightly less reliable
App experience isn't as polished
Object avoidance still trails Roborock
3. iRobot Roomba Combo j9+

The Roomba name still carries weight, but the Combo j9+ faces tougher competition than ever.
Its dirt-detection technology remains impressive, allowing the robot to spend extra time cleaning heavily soiled areas. For homes with pets, that's genuinely useful.
However, its overall cleaning efficiency isn't quite at the level of the Roborock or Ecovacs. It often requires additional passes to achieve similar results, especially on thicker carpets.
What It Does Best
Smart dirt detection
Excellent build quality
Strong customer support
User-friendly software
Where It Falls Short
Lower suction performance
Slower cleaning times
Less effective deep-carpet cleaning
Navigation and Obstacle Avoidance
Roborock Leads the Pack
Modern robot vacuums live or die by their navigation systems.
The Roborock S8 MaxV Ultra consistently avoids cables, shoes, pet toys, and other household obstacles without sacrificing coverage. That's a big deal because a robot vacuum that constantly gets stuck quickly becomes a chore instead of a convenience.
The Ecovacs Deebot X8 Pro Omni performs well but occasionally makes questionable route choices.
The Roomba Combo j9+ is reliable overall but can be more conservative, sometimes avoiding areas that could have been cleaned.
Which Robot Vacuum Handles Pet Hair Best?
Pet owners tend to have higher expectations from robot vacuums, and for good reason.
Winner: Roborock S8 MaxV Ultra
The dual rubber brush system resists tangles better than most designs and does an excellent job lifting embedded hair from carpets.
Runner-Up: Roomba Combo j9+
Despite ranking third overall, Roomba remains one of the strongest choices for pet-heavy households because of its dirt-detection technology and proven brush design.
Third Place: Ecovacs Deebot X8 Pro Omni
Still very capable, but long pet hair can occasionally wrap around components more frequently than the competition.
Value for Money
Best Premium Buy
Roborock S8 MaxV Ultra ($1,899.99)
If you're spending flagship-level money, this is the robot vacuum most likely to replace a significant portion of your manual cleaning routine.
Best Feature-to-Price Ratio
Ecovacs Deebot X8 Pro Omni ($1,099.99)
You get cleaning performance that comes remarkably close to the Roborock while often costing less.
Best for Brand Loyalty
Roomba Combo j9+ ($1,399.99)
A solid performer with strong support and reliability, but it's harder to justify purely on cleaning performance compared with newer rivals.
Final Verdict: Which Robot Vacuum Actually Cleans Properly?
After comparing cleaning performance, navigation, carpet pickup, pet hair handling, and overall reliability, the rankings are clear:
1st Place: Roborock S8 MaxV Ultra
The best overall robot vacuum for people who care about actual cleaning results. It consistently picks up more debris, navigates smarter, and requires less intervention than the competition.
2nd Place: Ecovacs Deebot X8 Pro Omni
An excellent alternative that delivers flagship-level cleaning performance and impressive mopping capabilities at a potentially better value.
3rd Place: Roomba Combo j9+
Still a capable robot vacuum, but competitors have overtaken it in raw cleaning effectiveness and innovation.
If you're buying a robot vacuum in 2025 and your primary goal is simply getting cleaner floors with less effort, the Roborock S8 MaxV Ultra is the one to beat.
