OKP B0915YCWD3 Robot Vacuum (Open Box)

THE PROS This is my second robot vacuum. What I like about this one is that it doesn't have a brush roll. I have dogs and their fur used to jam up the brush roll on my previous vacuum. This model has brushes on the sides to flick the dirt and debris toward the "mouth". (I'm not sure what else to call it.) It gets clogged once in a while, but it's simple to just pull put the lump of fur. Not complicated like unwinding hair (my daughters have really long hair and they shed like the dogs) from a brushroll. THE CONS My last vacuum came with floor strips that you could place across doorways, tops of stairs, etc to keep the vacuum from entering. This was helpful so that I didn't have to close all the bedroom doors to keep the vacuum out. (My kids leave clothes and charge cords and thing lay around in their rooms--things the vacuum would get hung-up on.) This one doesn't have that feature. It has sensors so that it doesn't run into things like furniture, but the sensors don't notice things that aren't at least a couple inches tall. The run time is close to an hour. That's plenty of time to clean my living room and kitchen, but if you have a larger space or more rooms the battery may not last. The biggest con is that the app stopped connecting to the vacuum. I LOVED the remote feature. Especially so that I could keep an eye on battery level, but it hasn't worked for a long time. I've had the vacuum about 18 months and for the last half of that, I've been patient, hoping app updates would correct this, but every so often I try to connect the app to the vacuum and it fails to pair. It's not user error. It's a fairly simple process and I've done it before. If the app worked I'd have given it four stars.
