iRobot Roomba i3+ (3550) Robot Vacuum with Self-Emptying Clean Base Automatic Dirt Disposal - Smart WiFi Connected for Pet Hair & Hard Floors - Ideal for Homes with Pets & Busy Families

This is my second robot vacuum. My first robot vacuum was a no-name brand had a lot of suction, but only randomly ran around my house. It didn’t auto empty and cleaning it out every day was is a chore. Also it definitely missed areas.The iRobot i3’s software is a huge upgrade for my first robot. It learned my house and help me set up the rooms. I can have it clean a specific room just using my Alexa (or the app) or I can have it clean the entire house at once. It has a very good job cleaning my house. I have two dogs, one of which is a border collie and I’m using it every day. I don’t see any dog hair in my house as it does a great job at picking it all up. And I have it set up to go back-and-forth instead of randomly around rooms and it finds a dirty spot to hit that area two or three times. It always finds its way back to its base and south empties, which is a huge improvement from my previous vacuum which many times will get stuck or run out of power before it found its base. I love the auto empty feature, but my bag in the base only lasts about two weeks I’m guessing because of the dog hair. The manufacturer says 6 to 8 weeks. But with the trade-off of not having to clean it every day, I am willing to change the bag every two weeks. Also for comparison, the area I have it cleaning is a little over 1,100 sqft(BTW: it takes about 10 seconds to change the bag in the base.)The vacuum is quiet while cleaning but if it needs to empty its tank, the base is quite loud for about 8 to 10 seconds while emptying. If you work from home, you may want to consider scheduling the vacuum at a time when it won’t interfere with your work if you have to take calls or be on zoom. (Or the app allows you pause the vacuum & resume the cleaning later) I also like that it will return to its base and charge and then go back and finish the job picking up right where it left off. So far this vacuum has worked great and I highly recommend it. If anything changes I will update this review.
