The Roomba j7+ has some pretty solid mapping and navigation features. It uses this advanced smart mapping tech that helps it move around your rooms efficiently without skipping spots or getting stuck. According to the manufacturer's description, it has PrecisionVision Navigation, meaning it can spot and avoid obstacles like cords and pet messes—handy if you've got pets or a lot of stuff on the floor.

It uses a combo of cameras and sensors to map out your home accurately and cover all areas well.

Another plus is its size; it's pretty compact at 13.3" x 13.3" x 3.4". The manufacturer says this smaller height helps it get under furniture like couches and beds where taller vacuums might have trouble.

It also features dual multi-surface rubber brushes and strong suction, which are great for picking up dirt, debris, and pet hair. From our research, many people have mentioned that the smart mapping really helps the Roomba navigate through different rooms and adapt to changes.

It also does a good job identifying no-go zones and setting up cleaning schedules, which you can adjust using the iRobot Home app.

So, if you're looking for a robot vacuum that balances size, suction power, and smart mapping, the Roomba j7+ is a solid pick for keeping your home clean without much hassle.

The iRobot Roomba j7+ works pretty well on carpets, especially when dealing with pet hair. Based on our research, its powerful suction and dual multi-surface rubber brushes make it good at picking up pet hair on both hard floors and low-pile carpets. The rubber brushes are also designed to avoid tangling, which helps keep the cleaning consistent.

However, if you have high-pile carpets, there are a couple of things to keep in mind. From what we found, folks with pets that shed a lot, like Golden Retrievers, are pretty happy with how the j7+ handles pet hair. But some mentioned that on high-pile carpets, it might need a few extra passes to get everything clean.

The rubber brushes help with detangling, which means less maintenance compared to traditional bristle brushes, but you might still need to do some manual cleaning for those stubborn hairs.

Also, the obstacle avoidance technology of the Roomba j7+ is great at keeping it from getting stuck, but it might miss some spots near obstacles like furniture legs where pet hair can pile up. So, you might have to clean those areas yourself every now and then.

Regular upkeep is crucial to keep the Roomba j7+ performing well. Make sure to clean the brushes and empty the bin frequently, especially if your pets shed a lot.

All in all, the Roomba j7+ is a good choice for pet owners. It handles pet hair well on different floor types, including low-pile carpets, even though it might need some extra work on high-pile carpets. For more details, you can check out its reviews and specs on its Amazon page.

The iRobot Roomba j7+ is usually pretty quiet when it's cleaning, but it gets noticeably louder when it's emptying its bin. According to our research, the noise from the Clean Base™ Automatic Dirt Disposal is kind of like the sound of a standard vacuum cleaner.

It can be a bit jarring, but the good news is that it only takes a few seconds to finish up. So while you'll definitely hear it, it won't go on for long.

If you're in an apartment with thin walls or if you usually run the Roomba late at night, this noise could be a bit of an issue. But if you're out during the day or have other noises going on, you might not even notice. It's really about what works best for your situation.

So, in short, the Roomba j7+ does make more noise when it's emptying its bin, but only for a brief time and it's about as loud as a regular vacuum cleaner. It's a small trade-off for the convenience of not having to empty the bin yourself.
