iRobot offers three-for-two deal

Is the company trying to beat the holiday discount rush or making room for newer models in the pipeline?

iRobot's Roomba, Scooba, and Dirt Dog are selling bundled for $900. iRobot

iRobot is offering deep discounts on its home products if you buy directly from its Web site.

We're wondering why, and it comes down to two possibilities, really.

One, they have newer, brighter, shinier models in the pipeline and need to unload old stock. Or, two, they're simply trying to get a head start on the holiday-season discounts expected from retailers, given the state of the economy.

Most recently, iRobot sent an e-mail letting people know it's offering $50 off its Scooba 380 model if you buy it before October 24. It normally sells for $450. That discount is presumably in preparation for the new Scooba 385 that it promises is "coming soon" on its European Web site.

iRobot is also offering $25 to $100 off its Roomba models when you buy two.

But if you have a lot of cash lying around, you could save even more. The company has a series of value packs in which they'll give you three robots for the price of two.

If you buy a Roomba 570 vacuuming robot and Scooba 380 floor-cleaning robot for $900 directly from the company Web site, for example, iRobot will throw in its Dirt Dog shop vacuum for free. They also offer combos that include the Looj gutter-cleaning robot.

Considering that averages out to $300 per robot, it's really not a bad deal.
