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.
