![]() If you have decided to get an iRobot Roomba vacuuming robot so you may never have to manually vacuum your home again, and you don't want to pay the higher prices of the 900 series Roomba robots, you might want to consider Roomba 890 or Roomba 650.
Roomba 890 comes with some of the important features found on the 900 series robots such as AeroForce vacuuming technology with debris extractors, a Lithium-Ion battery and Wi-Fi support, without costing as much as the 900 series robots. Though Roomba 650 will not offer you all the features Roomba 890 comes with, it still comes with enough must-have features, such as good floor coverage, auto-recharge, and scheduling, that make it quite acceptable for most homes.

Explanation of Notes 1 to 13 from Comparison Table:
N. 1:
The iAdapt responsive cleaning technology composed of sophisticated software and sensors allows Roomba robots to clean more thoroughly the room, making multiple passes, avoiding stairs, getting under and around furniture, and cleaning along wall edges and corners. The low profile design of these robots allows cleaning under most furniture. They also automatically adjust to all floor types - carpet, tile, hardwood, laminate and more.
An important aspect of iAdapt technology is Dirt Detection:
Finally, note that Roomba 650 comes with one Virtual Wall, while Roomba 890 comes with one Dual Mode Virtual Wall Barrier. These are little standalone devices that are used to keep away the robot from rooms or areas they are not supposed to enter:
The following pictures illustrate Virtual Walls and Dual Mode Virtual Wall Barriers in action:

The low profile design of these robots allows cleaning under most furniture. They also automatically adjust to all floor types - carpet, tile, hardwood, laminate and more.
An important aspect of iAdapt technology is Dirt Detection:
- Roomba 650 is equipped with acoustic sensors which allow them to find dirtier areas and spend more time cleaning them.
- Roomba 890 comes with more sophisticated dirt detection ability. It is equipped with both acoustic and optical sensors, and therefore it is more powerful and effective when looking for dirtier areas.
Finally, note that Roomba 650 comes with one Virtual Wall, while Roomba 890 comes with one Dual Mode Virtual Wall Barrier. These are little standalone devices that are used to keep away the robot from rooms or areas they are not supposed to enter:
- Virtual Walls are tiny devices that emit an infra-red beam that the Roomba will not cross. It is used to stop the Roomba from entering areas not wanted to be cleaned. It can be set to block an area ranging from three to eight feet long.
- Dual Mode Virtual Wall Barriers, like Virtual Walls, can be used to block off an open doorway, but they can also be used as Virtual Wall Halos to protect some restricted area within the room, such as the area you where your dogs food is placed..
The following pictures illustrate Virtual Walls and Dual Mode Virtual Wall Barriers in action:
N. 2:
Roomba robots use a 3-stage vacuuming system:
N. 3:
The tangle-free brushes (also known as debris extractors) found on Roomba 890 grab and break down debris, eliminating hair tangles and jams, and an airflow accelerator creates a sealed channel that concentrates airflow, sucking in more debris.
N. 4:
When Roomba 890 is connected via Wi-Fi to your smartphone, you can use the iRobot Home App for Android and iOS to invoke remotely operations (such as cleaning, scheduling, etc.).
Note that Roomba 890 is compatible with Amazon Alexa. Simply ask Alexa to start, stop, or dock your robot.
N. 5:
N. 6:
Scheduling can be pre-set up to 7 times per week. The robot starts vacuuming as soon as the scheduled time is reached.
Both robots can be scheduled.
N. 7:
When batteries run low, both Roomba robots return to their Home Base to dock and recharge.
N. 8:
Both robots are equipped with a Home button that can be pressed to force the robot to dock at its Home Base. Of course, the robot will also go automatically to its Home Base when battery runs low.
N. 9:
Both robots cab be asked to spot clean. When spot clean is invoked, the robot will spiral approximately 3 feet in diameter and then spiral back to where it started for an intense, localized clean for those quick fixes.
N. 10:
Roomba 650 has a Nickel Metal Hydride (Ni-MH) battery, while Roomba 890 has a Lithium-Ion battery.
Lithium-Ion batteries are designed to provide longer cleaning sessions and last longer before needing to be replaced.
Battery Run Times:
For both robots the average run time is about 60 minutes,.
Note that run times can vary extensively depending on the amount of work the robot has to do to clean the floors. That is because different types of carpets, different floor plans and different amounts of dirt may require different amounts of effort from the robot and hence different amounts of ''juice'' from the battery.
However, keep in mind that Lithium-Ion batteries are designed to provide longer cleaning sessions.
N. 11:
N. 12:
The "d" in the dimensions refers to the diameter, and "h" to the height of the unit. All measurements are in inches.
N. 13:
The 1-year limited warranty is on the robot. There is also a 6-month warranty on the battery.
N. 2:
Roomba robots use a 3-stage vacuuming system:
- Counter-rotating dual multi-surface brushes (on Roomba 650) or counter-rotating dual multi-surface tangle-free brushes (on Roomba 890) pick up dust, debris, dirt, pet hair from the floor. Note that the tangle-free brushes are also called debris extractors.
- A spinning side brush cleans along wall edges.
- Finally, an efficient vacuum pulls dirt and hair off the brushes (or off the debris extractors) and directs it into the bin.
- AeroVac technology found in Roomba 650 uses dual counter-rotating brushes and allows for optimized airflow that pulls hair off the brushes and sends it into the bin. This allows the bin to fill more evenly requiring less frequent emptying of the bin.
- AeroForce technology found in Roomba 890 introduces the dual tangle-free brushes (debris extractors) and delivers an ideal balance of vacuum suction and debris extraction: These tangle free extractors grab and break down debris eliminating hair tangles and jams, and an airflow accelerator creates a sealed channel that concentrates the airflow, sucking in more debris. Thanks to the high efficiency vacuum, the air power is increased 5 times in Roomba 890 compared to Roomba 650.

N. 5:
- The AeroVac filter found in Roomba 650 handles quite adequately hair, pet fur, lint and carpet fuzz, but not as well as AeroForce High Efficency filters do.
- Roomba 890 is equipped with an AeroForce High Efficency filter that can capture 99% of allergens, pollen, and particles as small as 10 microns.
