Square/new Roomba coming sooner than later?

Could a new Roomba be hitting the streets? Tipster Kason Jinkaid writes:

Not sure if this excites you, but I heard from a Costco salesperson
that they’re getting new Roombas “soon”, though that could mean
months. They aren’t stocking the ones they’ve been carrying (model
550). Also Woot just sold off a bunch for 535s for ~$100 less than
what they usually sell for, so are probably clearing out inventory.

If anything, you can get yourself a cheap 550 or 535?

I doubt sincerely this means the arrival of the square Roomba we talked about last week but it could mean a refreshed model going out to big box stores. We’ll investigate a bit.
