Reviewers praise
  • Exceptionally efficient navigation and coverage, with best-in-class mapping speed and cleaning patterns
  • Strong vacuum pickup on both hard floors and carpet, with very good deep-clean performance on embedded debris
  • Large 350ml water reservoir allows extended mopping coverage before refills
Reviewers push back
  • Mopping performance is only adequate for light spills; the non-vibrating, non-lifting pad struggles with baked-on stains without multiple passes
  • Lacks dedicated carpet sensor, so users must manually create no-mop zones to protect rugs
  • Combined dust bin and water tank design results in a smaller air filter with less surface area
Reviewers agree the Q7 Max+ excels at vacuuming hard floors and carpets with exceptional navigation efficiency, but mopping performance is merely adequate and the price sits uncomfortably close to higher-tier models.
— best for: Buyers with mostly hard floors who prioritize vacuum performance and mapping intelligence over mopping capability, and who want automated maintenance via auto-empty dock.
Reviewers disagree · Q7 Max+?
Vacuum Wars 4.5/5
Simon's Reviews 3.0/5

One reviewer finds the mopping better than expected for a robot vacuum, while another explicitly states it falls short and recommends a different model for serious mopping needs

This keyboard is wild! The size is super nice for a smaller desk! The key caps feel smooth, yet tactile. Being hot swappable, cleaning them is an absolute breeze. The little OLED screen in the corner is a fantastic feature to have, and you can customize it in their app! Having the option to switch between Bluetooth, and the seamless wireless mode they have has been incredible. It’s crazy the keybo Andrew E · influenster.com

Bought the Q7max+ a few days ago and I’ve been super impressed! I love this robot so much I told my husband it’s my robobaby 😂 it came with a dust bag installed and an extra one in the box! First off, I’m not new to cleaning robots so this is an absolute game changer, especially with the auto emptying dock! You can control it all from the app, even while away from home, at work, at the store!! yo RoboBaby · us.roborock.com
