I just got one of the Shark IQ Robot vacuums, and it is awesome ! We had a Roomba years ago, and loved it until it accidentally got wet and ruined it, and I have been wanting another one ever since.
I browse eBay, and came across the robot vacuum on there, and made an offer of $45, and they sold it to me, It was used, but looks like new, and came from a company that buys electronics, repairs, and re-sells them.
This one connects with WiFi, and will map out your home, and has an app with it, so you can literally tell it which rooms you want it to clean, and when to start, and it will do it.
I have not tried that yet, we just got it set up and turned it loose to vacuum to see how well it did. It did a great job, was easy to clean, and found its way back to the dock and is charging itself back up.
You do have to go around and make sure that any cords or anything that it could get tangled in are all picked up before you let it vacuum, but we pretty much have to do that with the regular vacuum also.
Here is a picture from Amazon of the kind that I bought, and I am pleased that I got mine so cheap.
