Do you like vacuums? 
I really enjoy robot vacuums where I don't have to do any manual vacuuming!
Do you have a Neato vacuum? 
Yes, that is the brand I bought. I think it's one of the best inexpensive brand for robot vacuums that includes laser mapping.
I have a D7 Neato vacuum, I think it is great. 
I have the D4. I like how the cheaper models for 300 and less include the same laser mapping feature as the more expensive models. Other brands either don't include laser mapping or they are too expensive.
I think the D7 is great, but you are right, it is expensive? 
I also like how it has an app and can be controlled through it. You can set a schedule or turn it on from your phone.
Yes, the D7 can connect to the internet too, crazy how this works!
I set the schedule to run at a certain time every few days! It's so great not having to vacuum myself.
