This Matrix shark vacuum is great. I don't really need another ap on my phone for a household device, but this one is easy to use and you can pretty much set it and forget it. The vacuum does an initial "mapping" run in your house and has surprising accuracy. Then you can program a schedule and not need to worry about it. The only thing I would change is that the dust collection bin is in the back where the device meets the charger, so you have to pull it off the charger to empty it.
