Let's check in now with Wall Street Journal personal tech columnist Jeffrey Fowler who has seen this up close Jeff good morning. -- know it's it's great to talk to about something like this. What kind of test did you put. The robot vacuum throw. I'd like to regroup a vacuum threw them some tests I can imagine it would like that the underground. Like put three these guys. In a range and they compare how well they can. All different kinds of which Nigeria I tried Eminem. Patrick Sheehan from the beach a tractor you mean I tried it and then I also look -- who's around my house. So we're really kind of try to -- -- the southern baptists -- only a look -- it does does not even your bad but also. Really which one can. At the most open -- floor. How does this thing get around dining room chairs table legs. And other things that are in the way. The short answer is not released very well. You know that technology has been around for attempting years. And they have definitely been some improvement. On some of these models won't -- -- -- Actually no argues is that shame. Kind of and navigation technology that in this Google stock trading cards so that makes a MacBook courtroom and then. Very methodically tried to follow that -- based on what you eat out there. However when I tried it in my. Around my house and also in that. But you're down kind of ten that I mentioned Hewitt but it chair in the middle. I found that neat -- what you get caught up in the torture and it turned out it was actually a little bit more work.

Getting when these guys to the mean it's basically. Your alliance that. Actually none of them are very good options are put down about four counts is the hand on this big area around I. And none of these three -- product and it would mean that rumba. One means by. Optical Titus and another one that needle one. I'm none of them picked it's a popular quarter of this -- electric. So probably -- -- just still don't have enough power compared to you you'll actually upper. -- without that 700 dollars Florida news top of the line. Rumba back creator.
