Features & Specifications
The iRobot Roomba 780 offers plenty of convenience and can really help get a grip on dust, pet hair and debris on a variety of flooring surfaces.
The unit offers a three stage cleaning process to raise dust from carpet, brush it loose and vacuum it up. This cleaning process also gathers debris on polished concrete and manufactured wood flooring.
Small Dust Bin
The iRobot Roomba 780 is a very low profile robot vacuum, measuring under 4 inches / 10 centimeters tall.
Even if half the vacuum body were dedicated to bin space, you’d still have to empty the bin repeatedly. This is a common issue with all robot vacuums and not specific to this model.
This machine is very easy to set up and program. Follow the steps in the Roomba 780 manual, install the batteries for the lighthouse sensor, and charge it up. To monitor the first vacuuming session, just push CLEAN and watch the Roomba wander off!
Depending on your cleaning needs, the iRobot Roomba 780 vacuum cleaning robot can be programmed for seven different cleaning sessions per week, or just hit the CLEAN button. The unit will return to the charging station when it needs more power.
The Roomba 780 can work where you’re not, so you can get something else done.
You can define cleaning areas for the Roomba 780 by manually closing doors, or creating virtual walls.
Establish virtual walls to protect yourself from distractions caused by vacuum noise.
The Roomba 780 offers a full complement of detailed sensors that can learn the layout of your home for efficient cleaning. These sensors include:
- A room to room review via lighthouse beacons
- Contact sensors to limit scuff marks along walls or furniture while cleaning along baseboards and kickplates.
Cleans One Room At A Time
The lighthouse programming offered with the Roomba 780 means it will only clean one room at a time before it moves off to the next space.
If you have a small room (such as a bath) it’s a good idea to block open the door so the Roomba doesn’t accidentally shut itself in.
Be prepared to be amused when you watch the Roomba 780 bobble off around your home. At times, it moves in a straight line. At other times, it wobbles off every which way. Both methods of movement result in clean floors!
Roomba 780 Gets Lost and Stuck
You may find that the unit gets stuck on transition zones, or can’t find its way back to the charging station.
The Roomba 780 is not nearly as loud as traditional vacuums and can easily be run while you’re home without disrupting your time at home.
You can set up virtual walls or physically shut it in the space you want cleaned and enjoy quiet and clean floors at the same time!
If allergies are a problem, this robot vacuum can be a life-changing tool. The dust level in your home may drop rapidly with a daily vacuuming program.
Counter Rotating Brushes Need Frequent Maintenance
The three step cleaning phases of the Roomba 780 include counter rotating brushes that work to gather up pet hair and debris.
These brushes can get clogged with string, hair, and other long fibers that can limit the vacuum’s power, so you’ll need to check and clear these every third round of vacuuming.
Leaves Behind Clumps of Hair
The combination of spinning and rotating can cause pet hair to bunch or ball up. The machine will then clear these as though they are debris, so you may wind up gathering hairballs after each vacuuming session, particularly along transition areas.

Other Important Information
No iRobot Roomba 780 review would be complete without a comparison between this machine and an upright.
Will a robot vacuum and an upright complete the same chores?
No. Robot vacuums cannot be used on stairs. However, if you invest in a robot vacuum, you can handle the rest of your vacuuming needs with a small upright or a hand vacuum.
What about power?
Depending on the upright you’re used to, you may think that it has more power than the robot vacuum.
The difference between the upright and the robot vacuum is the intensity of the brushing, the power of the rotating brushes and the frequency of vacuuming sessions.
The iRobot Roomba 780 can happily vacuum your house all day long. Few homeowners can commit this amount of time.
Is it worth the money?
Depending on the members of your household, your own cleaning preferences and your tolerance for dirt, a robot vacuum may not be a good purchase. It’s not a necessity, and some may see it as a luxury.
Busy professionals can learn to love coming home to a freshly vacuumed home. For parents of young children and pet owners, a Roomba 780 can pick up a lot of dog hair and dirt.
This is especially important if you have toddlers who are prone to picking up stuff and putting it in their mouths.
Additionally, retirees may appreciate an easy to handle 13 pound vacuum instead of a heavier, more cumbersome unit. With careful maintenance, you can keep your Roomba working hard for years to come.
