Yeah, the iRobot Roomba Combo j9+ is pretty good at dodging obstacles. It has some fancy mapping and navigation tech that lets it smoothly move around stuff like furniture and pet bowls.

From what we've found, people generally think it does a great job avoiding things without getting stuck or knocking stuff over. So, you can leave it to clean without needing to keep an eye on it all the time.

The PrecisionVision Navigation system is a big part of how it handles obstacles so well in real-time. Plus, it’s smart enough to detect when it's moving from hard floors to carpets.

Thanks to its Auto-Retract Mopping System, it lifts the mop pad to keep your carpets dry while it vacuums.

That said, some folks have mentioned running into the occasional mapping error or connectivity glitch. And a few have noticed that the mopping feature might leave streaks or not scrub thoroughly in certain spots.

Regular software updates and a bit of maintenance can help sort out these issues.

In a nutshell, the Roomba Combo j9+ does a solid job with obstacle avoidance, making it a good pick for keeping your place clean, whether you have hard floors, carpets, or both.

Just keep in mind that like any tech, it’s not perfect and might need a bit of upkeep now and then.

The iRobot Roomba Combo j9+ is designed to handle both vacuuming and mopping, so it's natural to wonder how it does with pet hair. Based on what we've found, it has its ups and downs. Here's the scoop on its performance with pet hair.

Strengths

Vacuuming Capability

From our research, the vacuuming part of the Roomba Combo j9+ does an excellent job with pet hair. It has strong suction that works well on both hardwood floors and carpets. Many folks have mentioned how effectively it picks up pet hair, dirt, and other debris.

So if vacuuming is your main concern, this model does pretty well.

Weaknesses

Obstacle Avoidance

Obstacle avoidance seems to be a weak spot. The Roomba j9+ can have trouble navigating tight spaces. It often bumps into walls and furniture before moving on, which could lead to some minor scratches and potential damage.

Reliability and Error Codes

There are some reliability issues to be aware of. According to our research, people have run into error codes and problems with the self-emptying bin. These can be pretty annoying and interrupt the cleaning process.

Mopping Function

While it's great at vacuuming, the mopping function could be better. It tends to be inconsistent, leaving streaks or missing spots, especially on tougher surfaces like carpets—which it really should avoid during mopping.

App Experience

The app that comes with the Roomba Combo j9+ has its issues too. Users have complained about it being slow and buggy, which makes controlling the robot less than ideal. The mapping feature also doesn't always work well.

Customer Service

Customer service has had mixed reviews. Some people have had positive experiences, especially when dealing with warranty claims and replacements, but others haven't been as lucky. It seems to be hit or miss.

Final Thoughts

The iRobot Roomba Combo j9+ does a great job with vacuuming pet hair, but it has its shortcomings, like inconsistent mopping, poor obstacle avoidance, and some reliability issues.

If you're mainly focused on vacuuming, it could be a good choice. But if these issues sound like deal-breakers, you might want to check out other models or brands.

Hope this helps you decide!

The Roomba Combo j9+ battery life is a bit of a mixed bag, depending on how you use it. The manufacturer says it can run for up to 75 minutes per charge.

Based on our research, though, you can expect something closer to 60 to 75 minutes most of the time. Things like cleaning mode, floor type, and your home's layout can really affect how long it lasts.

For small to medium-sized homes, this should work just fine. If you've got a bigger place, don't worry; the Roomba will head back to its dock to recharge and then continue cleaning where it left off.

So, while the battery might not last forever in one go, it gets the job done eventually.
