if you dogs that it was entertaining. Maybe I can get the robot to feed the dogs like a robot dog sitter.Roomba 805 vs 880

Roomba 960 is better than Roomba 890. But Roomba 960 price is high, but still, it's value for money and worth it. It has some great features as well. It uses  iAdapt 2.0 technology to navigate. So, I would this one is good. 

Great, funny and useful thread! I have a dog and a cat at home. Of course, there is a problem of cleaning their hair off the floor.  Recently I've decided to buy iRobot in the hope it will help me. Can someone tell me what model is a good and not very expensive one? I found a review of three popular Roomba models on https://smartercomputingblog.com/roomba-890-vs-roomba-960-vs-roomba-980/ and I find it useful, but it would be great if you guys could share your experience. Thanks in advance!

Found this review site very use full for Roomba vacuum as was not sure which one to buy for my hardwood floors, my 2 dogs don't make too much mess but these are a lot less noise than the upright vacuums

Here are some reviews of both high-end and budget options you can try

Not at all it is not going make your condition more worse but some time you have to monitor the vacuum as it stuck in solid objects but the high-end vacuums do well. 
I don't think that you are saying. My pet is okay with robotic vacuum cleaner.

Deebot will be the best vacuum to have read Deebot m80 review  to have more indepth knowledge.

i have also bought new vacuumm recently, it is amazing.
