robot vacuums, what do you have

anyone have input on robot vacs? I used to have a roomba a few years back and it was medicore but it did get some dirt and hair up... i'm a big fan of dyson even though they're pricey. We have an upright ball thats great and a v6 absolute thats awesome too but not sure how the robot is. Just need something to vac our hardwood in between when the housekeeper comes as we have a Labrador that sheds a lot and an infant that doesn't need to be covered in dog hair. Seems like most of the coices have decent suction for hard surfaces but the AI is what separates the men from the boys so to speak. I'd trust you guys over youtube university
