How these two compare on everything we measure — where the AIs rank them, what reviewers and buyers say, and how they price. The differences are the point — they decide which one is yours.

Every signal we hold, on one shared scale. The leading side is lit — and where the AI panel and the reviewers pull apart, the row says so.?
Built from what 4 AI models (Claude · ChatGPT · Gemini · Perplexity · AI Mode) recommend for real buyer questions, layered with reviewer test summaries, Google buyer ratings, street prices and press. The short answer and verdict are derived from where those signals diverge — not written by hand for either product.

What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Self-emptying base eliminates manual bin contact for weeks, bags seal automatically when removed
- Camera navigation creates persistent smart maps with room labels and no-go zones
- Dual rubber brush rolls pick up most debris types well on carpet and hard floors
Reviewers push back
- Hair and debris tangle around side brush and inside wheel wells, requiring manual cleaning every few weeks
- Struggles to pick up shorter pet hair tufts on hard surfaces despite repeated passes
- Camera requires light to navigate, will not operate in dark rooms
The i7+ delivers genuine hands-off automation with self-emptying and smart mapping, but demands frequent brush maintenance and struggles with pet hair tufts on hard floors.
Reviewers praise
- Extremely powerful suction measured at 22-25 CFM, the highest among tested robot vacuums, with outstanding carpet deep-cleaning that extracted over 90% of embedded sand
- D-shaped design with 30% wider front-mounted brush rolls reaches edges and corners far better than round robots, leaving minimal gaps along walls
- Dual rubber extractors handle hair exceptionally well with minimal tangling, requiring only simple maintenance instead of cutting hair from bristles
Reviewers push back
- Navigation uses older VSLAM camera technology that is slower and less methodical than lidar, requiring lights on and sometimes multiple mapping runs
- Battery life suffers significantly in high-power mode, often requiring mid-clean recharges that extend total cleaning time to several hours for modest homes
- Struggles audibly with larger debris, making crunching noises and showing it does not handle bigger particles smoothly
Reviewers agree the s9+ delivers exceptional cleaning performance with the strongest suction and best deep-cleaning ability they have tested, though it comes with navigation quirks and a high price.
One reviewer found maintenance minimal over six months with only one bag change, while another documented heavy hair and dirt buildup requiring deep cleaning after one month
Some reviewers found navigation adequate and thorough despite being camera-based, while others felt it lagged noticeably behind lidar precision and satisfaction
