Roomba Discovery SE: This model, shown in Figure 1-7, was released in 2004 and
improved in 2005. It is identical to the Discovery model except for the different colored
exterior and the inclusion of a self-charging wall mount in addition to the self-charging
home base.

Roomba Pink Ribbon Edition: This model, shown in Figure 1-8, was released in 2005
as a promotional version of Roomba and is functionally the same as the Roomba Sage
model. For every Pink Roomba sold, 20 percent of the sale price was donated to the
Susan G. Komen Breast Cancer Foundation, with a $45,000 minimum guaranteed
donation.
Roomba 2.1: This model, shown in Figure 1-9, was released in 2005 as a special
model sold only by the Home Shopping Network. It was the introductory model for
a makeover of the third generation. All Roomba robotic vacuum cleaners released since
then are 2.1. The 2.1 designator is a blanket term for over 20 enhancements to both
software and hardware. The software upgrade (called AWARE robotic intelligence)
includes improvements to the cleaning algorithms for better cleaning efficiency and
greater room coverage. The hardware improvements are perhaps more numerous and
include better battery-charging circuitry, improved brushes and sensors, and a better
vacuum design.
