Aspects and Features

The 790 follows a three stage cleaning process which consists of cleaning wall edges in the first stage and it makes a thorough job out of it. It has a specially formulated wall following technology which enables it to clean edges as well as corners thoroughly. In the second stage it uses a powerful vacuum to moves unwanted items and debris from the brushes into the bin. It does it very effectively due to an advanced cleaning head which is used in the machine.

The unit comes with a double layer of HEPA filters which makes it very efficient in trapping all unwanted material including dust and allergens. Once you switch on the machine you will have absolutely clean air in the room within minutes.

A cool feature in the machine that prevents it from falling off the stairs is the unique cliff detecting technology that Roomba has incorporated in the machine. With this technology, as soon as the 790 reaches a flight of stairs it will detect that there is a cliff ahead and not go beyond that point.

Another aspect of the Roomba is the wireless command centre with which you can control the machine. The wireless feature uses radio frequency technology, and the controls include the ability to schedule the cleaning and also to move the machine around the room. Using the command centre you can easily schedule cleaning up to 7 times in a week, even if you're out of the house.

Other Specifications

The 790 comes in dimensions of 13.9 x 13.9 x 3.6 inches, and weighs 17.2 pounds. When you purchase it you will also get one robot battery, one bristle brush, 2 HEPA filters, three Virtual Wall lighthouses, cleaning tools, screwdriver, and a carrying case.

Aspects and Features

The advanced technology used by the Roomba 880 enables it to ensure a very clean floor devoid of dust, dirt, debris and allergens. Roomba claims that it can clean 50% more of these unwanted materials making your floor absolutely clean. It is able to navigate in the room by itself and can clean the floor several times so that the room is absolutely clean. It pays more attention to areas which are dirtier than the rest of the room and focuses on them till the room is absolutely clean. It follows an automatic docking system by which it comes back and recharges itself.

You can schedule the machine to clean the room at a time that is convenient for you. Scheduling also includes setting the time for cleaning up to a maximum of seven times a week. Cleaning is very easy since an indicator informs you when the bin is full and needs to be emptied. It has a special spot clean mode which can clean a very dirty area in a short period of time for example, an area where dirt has piled up. It has a longer battery life due to special iRobot XLife technology that is used in the machine.

Other Specifications

The 880 measures 13.9 x 13.9 x 3.6 inches and has a shipping weight of 15.9 pounds. When you purchase the 880 it comes with one HEPA filter, a self charging home base, remote control, a Quick Start guide and manual, battery, and one extra HEPA filter.

What's the Difference Between the Roomba 880 and 790?

The HEPA filters in these machines work very well to remove dirt and pollen from the room. Due to the iAdapt technology the robots can navigate themselves without any issues. The extended life battery in both machines means that you do not have to replace the old batteries with a new one very frequently. 

While the 790 operates with Aerovac Series 2 technology the 790 has the AeroForce Performance Cleaning system both of which can clean very well. While both machines share most of the same excellent features the differences lie in the accessories that are available in the package. While the 790 is available with 3 Virtual Wall Lighthouses, extra flat and round brush and filter as well as a cleaning tool, the 880 is available with 2 Virtual Wall Light houses and an extra HEPA filter.
