What reviewers say

Distilled from the video reviewers — the score, what they praise, where they push back.?

Roomba i7+
across 5 reviews
3.5/5
mixed
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.
— best for: Best for allergy sufferers with mostly carpet who want truly automated vacuuming and don't mind occasional brush maintenance.
Roomba s9+
across 5 reviews
3.6/5
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.
— best for: Best for pet owners and those with significant carpeting who prioritize deep-cleaning performance and want automated maintenance without manual dustbin emptying.

I have an older Roomba that was living it's last days, and I knew that when I moved into my new house, I would have to upgrade because vacuuming is one task that I hate to do with a passion. I have twin toddler boys who make a mess and leave crumbles of food everywhere, so I was hoping that the i7+ would be able to handle all of it. And guess what? It does!

I’ve had my Roomba S9 for two years and it was the best investment I could have made for my home. It keeps my house clean daily by running around my house everyday. The face that it empties itself makes the process so much better. I like how effortless it is to use it. The smart capability lets me control it when I’m away from home. It is a magnificent product.
