A:AnswerSuction power is comparable to a standard vacuum, it will pick up dust bunnies as well as crumbs or bits or cereal. I have found it to be a nice hand-free vacuum so that the Roomba will do my weekly/biweekly vacuuming for me, with me only having to clean under areas the Roomba can’t get under such as low furniture or into couch cushions. Otherwise it has enough suction power and coverage to do just as good of a job as I would've done myself with a upright vacuum.
A:AnswerIt takes a few cleaning sessions for the Roomba to map your home and learn it’s way around it. I have found that on round 3 of cleaning my whole apartment it learned to avoid the stationary furniture in my home, like my desk, couch and coffee table. Furniture that moves position each time you use it, such as a office chair or dining room chairs, may still get bumped into still because they don’t permanently stay in one position for the Roomba to always know where to avoid. In summary, it will still bump into things for know while it’s still learning where things are but it should bump less over time :)
A:AnswerYou will connect the devise to your WiFi. Using the app you can monitor the progress of the job if you're not home. You can check the app and see the map of what was completed, if the job is on pause and the devise is back at the base charging, etc.
A:AnswerIt sees ok in the dark but don't get this for it to empty its own bin unless you have an 8 x 8 ft area that is completely clear. Otherwise it will always fail to dock.
A:Answers9 has a battery twice the capacity of i7.
s9 vacuums better than i7.
Hence s9 is noisier than i7.
s9 is a little lower or slimmer than i7 under furniture
s9 is “D” shaped to help do corners better.
s9 is 1lb heavier than i7.
Hence s9 is more costly.
A:AnswerAnswer YES…& NO !
Our ground floor is 2500sqft. i7s had to dock after 60min. Recharge ~30min and continue.
We decided to upgrade to S9s since battery is bigger capacity. Just couldn’t wait.
A:AnswerYes, ours transitions between wood, carpet and tile without an issue. The brush is rubber and not the traditional bristle, so it is MUCH louder. But it cleans well.
