The Roborock you buy will depend on which features you find the most important for your specific home. For example, if your home has more carpet than hardwood or tile, you’ll be safe with the Roborock Q5 or Q7+, depending on your budget. If you have varied floor types in your home or have children and pets that create many messes, the Roborock S6 MaxV or Dyad might be your best options.
