⚡ Major Differences
- Battery Life & Tank Size: S9 tends to give more uptime and larger tanks.
- Feature Richness: S9 comes with more smart sensors, better display info, probably more modes. S6 gives essential features only.
- Ease Under Furniture: S6 (especially Stretch types) wins in low clearance spaces; S9 may have better mobility but sometimes bulk works against it if you have lots of furniture.
- Price vs Performance Trade-off: S9 is “premium performance,” whereas S6 is value-performance.
FAQs
Is the S9 much heavier than the S6?
Yes, generally. Because of the bigger tanks, more robust motors, and premium build, the S9 tends to weigh more, making it slightly less maneuverable, especially upstairs or moving between rooms.
Will the extra runtime on the S9 matter every day?
If you regularly clean large floor areas or large homes, yes, that extra runtime matters. If your space is smaller (apartment, one floor), the S6’s runtime might be more than enough.
Which is easier to store and maintain?
S6 wins for simplicity. Fewer parts, less “premium” complexity means less to clean, fewer things that can break. S9 gives more but demands more care.
Does the S9 justify its higher tier for users who mostly clean daily messes (dust, small spills)?
Not always. If your messes are light, you may barely use many premium features of S9, so much of that cost becomes “nice to have” rather than must-have.
🧠 Final Thoughts
If I were you, want something that feels future-proof, that handles big messes or large spaces, and you enjoy gadgets, go S9.
If I wanted something reliable that gets the job done, doesn’t break the bank, and works well under beds and tables, I’d pick S6.
