Review on 🐶 Ideal for Pet Hair & Hard Floors: Renewed iRobot Roomba 981 Robot Vacuum with Wi-Fi Connectivity, Alexa Compatibility, and Power Boost Technology - Black by Marianne Green

The first few times you ride it, you should feel at home with it. We just vacuumed the day before, but this little Roomba picked up so much dust and dirt that it had to be cleaned multiple times when it first started up. The first few times she missed and seemed to stumble in confusion, but this thing is learning. Now it also navigates in the dark without using an optical sensor. It freezes charging once during cleaning and very rarely gets stuck as long as we don't keep the floors free of extra cords and the like. However, it's worth noting that the Wi-Fi and app functionality is completely useless. It all started with the application failing to connect to Roomba and now it continues to work on the previously set schedule even with a "factory reset”. It's annoying, but I'm not really mad about it. Worth the two lost stars as I chose this model for this functionality. However, I bought it used from Revain, so at least I didn't pay full price. (Check the seller. Unauthorized sellers can and do sell counterfeit goods through Revain. This is the second one I've bought. The other was returned.) In short? She is part of the family. We love her. She has made our house much cleaner and nicer.
