Which is better: Roborock S8 MaxV Ultra, Dreame L20 Ultra, or Roomba Combo j9+?

These three are all flagship robot vacuums, but they fit different homes best:

1. Roborock S8 MaxV Ultra — best if you want the most balanced, top-tier all-around cleaner. It’s a strong pick for mixed flooring and people who want a premium do-it-all robot.
2. Dreame L20 Ultra — best if your home is mostly hard floors and you care a lot about mopping performance. It’s often the most compelling choice when floor washing is a priority.
3. Roomba Combo j9+ — best for pet hair and obstacle avoidance, especially in carpet-heavy homes. Roomba’s dual-brush design is a good fit for hair-prone floors.

If I had to simplify it:

• Best overall: Roborock S8 MaxV Ultra
• Best mopping/hard floors: Dreame L20 Ultra
• Best for pets/carpets: Roomba Combo j9+

One caveat: exact dock size, mop behavior, and accessory details can vary by region and package, so it’s worth checking the official product page before buying.
