The Roomba S9 has a high-capacity lithium-ion battery and, according to the manufacturer, it can run for up to 120 minutes on a single charge. That's usually enough to tackle an average-sized home.
Once the battery is low, the Roomba S9 will return to its charging base on its own, and it takes about two to three hours to fully recharge before it's ready to go again.
From our research, most folks seem happy with the battery life, saying it's sufficient for cleaning multiple rooms or even a whole floor in one go. However, some have noticed the run-time can vary, especially if the vacuum has to deal with lots of clutter or thick carpets that drain the battery faster.
A handy feature is 'Recharge and Resume,' which lets the robot go back to its base to recharge and then pick up cleaning right where it left off. This is super useful for bigger homes or really deep cleaning sessions.

More Answers
If you're still curious about the iRobot Roomba S9 (9150), here are some other answers you might find interesting:
The Roomba S9 is pretty good at finding its way around, thanks to its Smart Mapping technology that creates personalized maps of your home. It can store up to 10 different floor plans, which is handy for multi-level homes.
But, it's not completely foolproof. From what we've found, it can sometimes get stuck under low furniture or tangled in cords, especially if your place is a bit cluttered. Keeping things tidy can help a lot.
Most people are happy with how it navigates, but a few have mentioned these occasional hiccups. So, it doesn't get stuck often, but it's not perfect either.
How often you'll need to empty the Roomba S9+'s dust bin really depends on a few things: the size of your place, how much dirt and debris it collects, and how often you're running it.
Based on our research, most people end up emptying the dust bin every 1-2 cleaning cycles, especially if they've got pets or if there's a lot of carpet around which tends to trap more dirt.
Now, if you have the S9+ model, it includes a self-emptying base that can handle up to 30 cleaning cycles, so you'll be emptying it way less often.
But with the regular S9, you'll want to keep an eye on the dust bin and empty it pretty regularly to keep it working well.
So, generally, plan on emptying it every few uses, but your mileage may vary depending on your home's specific conditions.
Yep, the iRobot Roomba S9 can handle cleaning multiple floors in your home. You don't need a separate Clean Base for each floor either.
According to our research, all you need to do is carry the Roomba to the different levels and set it up to clean there. Just make sure it has access to its dock on each floor for recharging. It might need to do a new mapping for optimal cleaning on each level, though.
From what we found, the Roomba S9 can remember multiple floor plans, which is great for homes with several stories. Sometimes it might need to remap the area when you move it to a different floor to get everything cleaned right, but once it's mapped, it should work without any issues.
Its powerful suction and other advanced features make it pretty effective for multi-floor homes, even though you'll spend a bit of time setting it up for each new floor. If you don't want to keep moving the dock around, you could buy an extra one for another floor, but it’s not a must.
So, if you have a home with multiple floors, the Roomba S9 is a good fit. It’s strong and adaptable, making it easier to keep your entire place clean.
