Financially, it apears to be a bad investment?
So, I have three floors in my house and I would need 3 botvacs at $1000 each. Since the typical reliability seems to be around 3 years (best estimates I can find based on internet complaints), I would to spend about $3000 again in another three years.
Mmmm, that's averaging $1000 per year or about $80 per month. Awfully expensive just to show off to someone that you can schedule a cleaning from your cell phone.
And all that expense only to receive a surface level clean...
Then again, for this Christmas, I can only imagine how many $400 Dyson Supersonics will be given as stocking stuffers.
