Roomba 510 Discontinued by iRobot?

UPDATED 3/26/08:
BREAKING: It appears that iRobot has decided to discontinue the Roomba 510, a bottom-of-the-line model of its new, next generation Roomba 500 series Roombas. The Roomba 510 no longer appears on the iRobot home page, and is now on sale at Woot.com for $154.99 shipped.

HSN has a better deal for a Roomba 535 for $212.49 Shipped in our Roomba Buyers Guide. (You can also get the Roomba 560 TODAY in the guide for $279.)

Of note, the Roomba 510 lacks an internal radio receiver so it CANNOT be upgraded for remote scheduling via the wireless command center and CANNOT be upgraded to use the new "Lighthouse" virtual walls, which contain Roomba in one room for a period of time and then release Roomba into the next room once the first room is clean. The Lighthouses result in more efficient cleaning overall because Roomba wastes less time going over already-cleaned areas. The Roomba 535 has the radio and comes with a Lighthouse virtual wall.

There also is a Woot-like deal for Scooba just $199 New in the Scooba Buyers Guide.
