Roomba 700 Series


The Roomba 700 series models were first introduced in 2011 and consist of four models in total: The Roomba 760, 770, 780 and 790. All four models share the same key technologies.


Key Technologies:

  • AeroVac2 bin technology fills the bin more evenly requiring emptying it less often. It also Roomba 700 Series- Series 600 on Steroidsprevents hair from getting caught onto the brushes less frequently.
  • DirtDetect Series 2 with “Persistent Path” (except for Roomba 760) that uses optical sensors to detect dirt and debris in addition to the same acoustic sensors used in previous models. This feature alone has made the 700 models better optimized than the 600 series models. Better dirt detection means that Roomba can determine where to focus additional “passes” which has made the overall product much more efficient. A critical mechanism for robotic vacuums is how they detect dirt. The cleaning algorithm of Roomba’s cleaning pattern is based on the data received from their dirt detecting sensors. This also explains Roomba’s somewhat “crazy” path patterns during a cleaning session. As soon as the dirt sensors let Roomba know there the  dirt is, the Roomba seems to get excited and that dirty area gets all its attention to make it spotless. In addition to acoustic sensors, the  new Roomba incorporates optical sensors to actually see the dirt. It all boils down to Roomba becoming smarter and smarter and more    The better the sensors detect, the better Roomba cleans.
  • The “Persistent Path” cleaning means that the  Roomba 700 series (except for the 760),employs an aggressive back-and-forth cleaning motion when its sensors detect dirty spots instead of the spiral patterns used in previous models which also contributes to a ng more effective cleaning.
  • Dual HEPA filters that capture dust particles as fine as 0.3 microns and encapsulates up to 98% of debris it encounters while leaving “clean air behind”. This is especially helpful for pet owners and people with allergies.


Feature Loaded:

  1. Full Bin indicators (except for the Roomba 760) that let you know when the bin has reached its full capacity and needs to be emptied.
  2. Touch pad control in models 780 and 790 as opposed to buttons in previous models.
  3. Wireless command center (for model 790 only). The Wireless Command Center lets you control all Roomba functions from up to 25 feet (7.6 meters) away. The Wireless Command Center is used to turn Roomba on and off, schedule up to seven cleaning times a week and steer Roomba around the room.
  4. IR Remote control (except for 790 model) allowing manual control of Roomba (if required) without “chasing” it. You can summon Roomba out of its dock remotely to tackle a dirty spot. How much fun is that?
  5. 3 cleaning modes: Clean, Spot and Scheduled.
  6. Lighthouse in models 780 and 790 to navigate between rooms providing for multiple yet separate room cleaning.
  7. Wall-Following Technology for smooth edge cleaning along the wall.
  8. Cliff sensors which allow Roomba to avoid stairs and other drop-offs.
  9. Molded soft-touch bumper cushions the contact between Roomba and furniture.
  10. Light-touch bumper technology differentiates soft barriers like curtains from solid objects, so Roomba pushes past soft obstacles.
  11. Larger dust bin.Roomba 700 Series With Lighthouse
  12. Battery life is 50% longer than previous models thanks to the sophisticated software on 700 series. Roomba 700 series are heavier and bulkier than 600 series. Their dimensions are 13.9” x3.6” vs. 13.39” x 3.62”. Weight is 8.3 lbs. vs. 7.9 lbs. It is 3.6” tall. Battery time is longer at 90 min. vs. 60 min..

Features by Model:

Model 700 series Roomba offers the same standard features as previous Roombas such as:

  • iAdapt Responsive Navigation – Roomba’s software which allows Roomba to navigate and adapt to your home.
  • 3-stage cleaning system: Agitation, Brushes and Suction.
  • Spot cleaning to thoroughly clean those dirty areas.
  • Self-charging Home Base – Roomba automatically docks to charge itself.
  • Voice “demonstration”- when a problem occurs Roomba will tell you what needs to be done
  • Low profile at only 3.6” tall.
  • Roomba 700 works on all kind of surfaces

Roomba 760 features:

  • AeroVac2 technology
  • DirtDetect Series 1 that uses only acoustic sensors to detect dirt
  • Dual HEPA filters
  • One Virtual wall
  • Remote control
  • Larger bin, – then previous 600 series
  • Longer battery life.

Roomba 770 is an excellent balance of affordability and features. It has many key features found onlyRoomba 700 Series Under the Hoodin the  800 seriess. It features:

Dirt Detect Series2 that utilizes both  acoustic and optical sensors to detect dirt. The brushes are more robust and maintenance for the Roomba 770 is easier as the gearbox is sealed. It has two Virtual Walls and Dual HEPA filters and  also comes with remote control.

Roomba 780 uses the latest generation Virtual Wall named “Lighthouse” which confines Roomba to one room until it is cleaned, before allowing it to move to the next room. The Lighthouse can also be used as a Virtual Wall to block areas. The Roomba 780 model comes with 2 of them.


High End Model 790 :


Roomba 700 Series -Remote ControlRoomba 790 is the high-end model of the 700 series. It also has room-to-room navigation – Virtual Lighthouse technology (it comes with 3 of them) and “Wireless Command Center” to control Roomba remotely from your computer. Since it comes with more sophisticated the “Wireless Command Center”, it does not come equipped with a remote control. This allows you to control Roombafrom any room in the house eliminating the need to be in the same room with Roomba to control it.



In My View:

Altogether the changes to the 700 series Roomba have made a good product even better. The Roomba 700 series are smarter and more powerful than previous models. The  Roomba 700 series provides you with that “elbow grease” type of cleaning power to get those  especially dirty areas clean and spotless.
