3. Why Roomba?
Roomba cleans your floors like no vacuum has
ever cleaned before - removing dirt, dust, pet
hair and other debris all on its own. Using
iAdapt® Responsive Navigation Technology,
Roomba vacuums every section of your floor
multiple times, getting under and around
furniture and along wall edges, detecting dirt,
avoiding stairs and navigating through loose
wires to clean more of your room, more
thoroughly.

9. Cleaning mode
3 cleaning modes:
Clean Mode – Roomba automatically calculates
the room size and adjusts its cleaning time
appropriately.
Spot Mode – Roomba will spiral approximately 3
feet (1 meter) in diameter and then spiral back
to where it started – an intense, localized clean
for those quick fixes.
Scheduled Cleaning Mode – Roomba leaves its
Home Base, cleans, and then returns to recharge
when it’s done.

10. Persistent Pass Cleaning Method
Employs a back and forth cleaning pattern to apply
elbow grease in areas where it senses excessive dirt
Cleaning- features
Tangle-Free AeroForce™ Extractors
Dual counter-rotating extractors incorporate a durable rubber
tread design that grabs and breaks down dirt and debris from any
floor type.
Airflow Accelerator
The accelerator brings the vacuum power right down to the floor
surface, creating a sealed channel that concentrates the airflow,
drawing in more debris.
High-Efficiency Vacuum
A compact and efficient high-powered motor provides a five
times improvement in air power than previous Roomba
generations.

11. Virtual Wall (Both 770 and 870 have 2)
Virtual Walls create an invisible barrier that your Roomba won’t
cross. That makes it easy to confine it to a particular room or
area, and prevent it from getting too close to anything delicate
or dangerous.
 Each Virtual Wall needs two C alkaline batteries (not
included).
 You can set the Virtual Walls to block an opening of up to 7
feet (2 meters). It creates a cone shape barrier, so the beam
gradually gets wider.
 For best results, place the Virtual Wall on the outside of the
doorway you want to block. Point the arrows on the top
towards the opening.
Virtual Wall mode: Roomba will not cross
Virtual Wall beam
10

12. Virtual Wall
Manual Virtual Wall
 Turn on a Manual Virtual Wall by hand at the beginning of the
cleaning cycle. It will shut off after 135 minutes. If the power
light blinks green, it means you’ll need new batteries soon.
Auto Virtual Wall
 When an Auto Virtual Wall is set to “AUTO” mode, the power
light continuously blinks to indicate it is on. When battery levels
are low, the Virtual Wall continuously blinks twice to indicate
that it needs new batteries. When in AUTO mode, the batteries
should last for around six months.
To save on batteries, just switch it to OFF
11

13. Virtual Wall Lighthouse (Standard with the 870)
In Lighthouse mode, it helps your Roomba navigate around
your home.
In Virtual Wall mode, it blocks off areas you don’t want cleaned.
Simply use the Mode Selector to make your choice. Either way,
it turns on and off automatically as you turn your Roomba on
and off. When on, the light on top is lit.
Each Virtual Wall Lighthouse needs two C alkaline batteries (not
included).
A flashing power light means the batteries need replacing soon A Virtual Wall Lighthouse can act as both a
Lighthouse and a Virtual Wall.

16. Even though all Roomba products are quiet enough for you to
sleep or watch TV while they are in use, the 870 model is even
quieter than the 770 model. This can be a great advantage for
a consumer that seems to pick up every single noise. It can also
help to reduce anxiety of pets that may get nervous with any
sounds in the home.
Quieter
 Model 870 is quieter than the 770 model

17. A robotic floor cleaner is certainly faster than doing
it on your own. However, the amount of time it
takes for the Roomba 870 to clean floors is less than
the Roomba 770. If you have large flooring areas or
the need to clean them often, this is definitely a
benefit you will be interested in.
Faster

Model 870 can clean the average floor in about
of the time that it takes for the 770 model to do
the same job.

18. When you look at the physical appearance of the
Roomba 770 and the Roomba 870, they are very
similar. However, the 870 model has the ability to
clean better. This is due to an internal design
change offering a sealed channel. This results in
suction power that is 5x what the Roomba 770
offers!
 Model 870
Cleans better

19. Both Roomba models go around and map out the
layout of the home. You don’t have to worry about
it damaging furniture or other items that are in its
path. These iRobots can memorize patterns in your
home. They can also learn new patters so don’t
worry if you rearrange furniture or get new furniture.

21. The design change of the Roomba 870
over the Roomba 770 also means you
empty it less often. The bristle free system
featured in the updated model takes up
less space than the previous design.
Empty Less
Often

Model 870 - The additional space has been used
in the Roomba 870 model to offer a larger dust
bin.
Model 770

22. It holds 60% more than the 770 model and that is a
remarkable improvement. The internal design difference
with this is that there is only one HEPA filter with the
upgraded model. The Roomba 770 features two filters.
Empty Less
Often

Model 870 - the filter has to be replaced less
frequently with the Roomba 870.

23. An iRobot Roomba isn’t cheap, but it can be a great
investment for keeping your home clean and saving you
time. The Roomba 870 costs about $600. The Roomba 770
retails for about $479. These prices are based on average
retail, but sometimes you can find some great deals online
or in retail stores that will save you some cash.
