Pros & cons

Roborock Q Revo MaxV

  • Excellent value with most S8 MaxV features at a lower price point
  • Dual spinning mop pads apply consistent pressure for better cleaning
  • Hot water washing dock keeps mops fresh between cleans
  • Strong 7000Pa suction handles pet hair and debris well
  • Reliable LiDAR + camera navigation rarely gets stuck
  • Suction is noticeably weaker than S8 MaxV on deep carpet
  • Single rubber + bristle brush tangles with long hair more easily
  • Mop lift height is lower than the S8 MaxV, occasionally dampens carpet edges
  • Dock still takes up considerable counter or closet space

iRobot Roomba Combo j9+

  • Innovative retractable mop fully lifts to the top of the robot over carpet
  • Same excellent carpet cleaning as the j9+ with dual rubber extractors
  • Smart mapping learns room types and adjusts cleaning behavior automatically
  • P.O.O.P. guarantee covers pet waste incidents
  • Quieter than most competitors at 65dB
  • No self-wash dock — you must manually clean the mop pad
  • Mopping performance is mediocre compared to dedicated mop robots
  • Camera navigation is slower than LiDAR and needs ambient light
  • Expensive at $1100 without a self-washing station included
