We've had Neato vacuums for years - my wife got this for me for Christmas - I finally got around to unboxing it and connecting it to our wifi - and then found out, the newest Neato D8, D9, D10 have issues with mesh wifi systems (our system is an Eero mesh wifi).  I spent about 20 minutes on it...then finally gave up.

So this should be completely fine as long as you don't have a 5ghz mesh wifi system.  If you have a standard 2.4ghz wifi router, it should connect with no issues.

The vacuum itself is brand new, never run, in the original box.
