The Roomba vacuum cleaner is made and sold by the

company iRobot. The Roomba was released in 2002

with updates and new models released in 2003, 2004,

and so on. These days, millions of them have been

sold, making it the most successful and popular

robotic vacuum cleaner thus far.


1. Remote control – This allows you to

control the Roomba remotely.

2. Schedular – This allows you to program

your Roomba to clean house on your schedule, even if

you are out. The schedular can also update a pre-2.1

Roomba robot to the 2.1 software.

3. Homebase – This is where the Roomba will

automatically return for recharging.

4. Virtual wall – This is used for keeping

the Roomba out of certain areas.

5. OSMO – This is a dongle that attaches

to the serial port of the Roomba.


The Roomba is a disc, 13 inches in diameter and less

than 4 inches high. A large contact sensing bumper

is mounted on the front half of the unit, with an

infrared sensor located at the top front center. A

carrying handle is fitted at the top of it as well.

Depending on the model Roomba you select, it can

come with one or two infrared transmitter units.

The first and second generation Roomba models

needed to be told the size of the room through the

use of three small buttons, although this is now

no longer required with newer Roomba generations.

The Roomba operates with internal nickel metal

hyrdide batteries and requires being recharged on

a regular basis from a wall plug, although the newer

generations have a home base where they will

automatically find and go to when they need to charge


Using the newer generations of Roomba consists of

carrying it wherever you would like to start,

pressing the power button, then pressing either

clean, spot, or max.

Whenever the clean, spot, or max button is pressed,

the Roomba will pause for second or two and then

begin work. The contact bumper on the machine

will detect bumping into walls and furniture, and

the virtual walls will limit the Roomba to the

areas that you desire. There are also 4 infrared

sensors on the bottom that will prevent the Roomba

from falling offer of ledges or down the steps.

Unlike the Electrolux models, the Roomba doesn’t

map out the rooms they are cleaning, as they

instead rely on bumping into objects or walls to map

things out. The design is based on MIT technology

that robots should be like insects and equipped

with simple controls mechanisms tuned to their


After a little bit of time, the Roomba will begin

to sing. If it detects a homebase, it will try to

return to it. At that point, you simply remove

the dust bin from the rear of the robot and empty

it into a trash can.

Keep in mind that the Roomba isn’t designed for

deep pile carpet. It is however, low enough to

go under your bed and most other furniture. If

at any time it senses that it has become stuck,

it will no longer sense the floor underneath it,

it will stop and begin to sing until you come and

find it.

If you are tired of vacuuming and simply don’t want

to do it anymore, a Roomba vacuum cleaner will be

a great investment. You can sit back and relax, or

go out and do things while the Roomba does all of

the vacuuming for you. There is nothing easier than

having a Roomba around, as it will help to simplify

things like never before.
