iRobot Roomba 790 Review

iRobot Roomba 790 uses iAdapt Responsive Cleaning Technology. That means iRobot Roomba 790 Vacuum maximizes cleaning by adapting to your household environment.

iAdapt Technology monitors the cleaning environment more than 60 times per second, using multiple sensors (like cliff detection) and dozens of behaviors (including wall following) to clean your home. It allows vacuum cleaner to clean hard to get places in your house.

Just like you, it spends more time cleaning the dirtiest areas of your floor, ensuring the cleanest possible results.

The Roomba is doing what I hoped it would. This is my first time experiencing this sort of technology, so this was a risky purchase for me.

However, the Roomba is nearly effortless to utilize, and it is picking up the dog hair, and more, from our carpets and wood floors without any hassle.- Buyer

iRobot 790 uses Roomba’s Dual HEPA filters which stop fine dust from circulating in your home, leaving behind fresher air. It seems you get 2 in 1 options. Robotic vacuum cleaner and air purifier.

The robot’s Dirt Detect Series 2 technology finds the dirtiest areas in your house hold and performs concentrated cleaning there, ensuring the whole floor is thoroughly clean.

Room to room navigation is possible with the included Virtual Wall Lighthouses, which confine Roomba to methodically clean one room at a time allowing the robot to move to the next room when finished.

You will always know when dust bin of iRobot Roomba 790 Vacuum Cleaning Robot is full. It has notification system and you will know when dust bin needs to be emptied.

With Roomba’s on board scheduling you can set up when you want it to start vacuuming. You don’t even have to be at home. It will automatically start cleaning as per your programing instructions.

iRobot 790 Roomba uses 3-stage cleaning process. It will vacuum carpets, hardwood, tile and linoleum floors on its own, automatically adjusting to different floor surfaces as it moves through your home.

It definitely is all floor robotic vacuum cleaner.

Roomba knows which areas to clean and which to avoid. As previously mentioned it uses iRobot Virtual Wall to clean one room and then head over to next one.

Roomba also charges itself, going back to its Home Base to dock and recharge between cleanings.

It picks up a decent amount of dog fur, dust, etc. around the house. It’s nice to just push a button and have it help out with the cleaning.

Obviously it can’t get in every nook and seems to randomly go around cleaning so will miss some areas. But it’s nice to have to help out with a majority of the cleaning.-Buyer

Disadvantages of Roomba 790 

  • Price. Price may vary depending upon where you’re buying it. But it goes something around 550-699$. Not cheap, not at all;
  • Still it cant be compared to traditional vacuum cleaners .If you run one of those over a floor previously cleaned by the 790, there is a fair chance you’re going to find that you have still picked up some additional dust and hair. But it is well-known fact that robotic vacuum cleaners are so that you don’t need to vacuum often. It is still needed from time to time to use traditional vac system;
  • Though quieter than many, it’s still a little noisy;
  • HEPA filters are expensive to replace and you are forced to use them;

How Does iRobot Roomba 790 Compare To The Competition?

It’s never easy to compare various robot cleaners to each other. Because if you want to be accurate, you’d need the controlled environments normally associated with a lab rather than a humble sitting room.

However, it’s possible to make some general observations about the 790 when compared alongside some of its major competitors like the VK range, Samsung and Mint.

roomba 790 vac system

Firstly, it seems to be right up there at the top in terms of technical sophistication. OK, there are some new models in Japan that apparently have voice-recognition built-in (if you can face talking to your vacuum cleaner) but they’re still largely novelty items.

The 790 and maybe VK are leading the pack right now in technology. Secondly, it comes from an established stable and that suggests expertise and past success.

 iRobot must be doing something right and you’ll get a good insight into that if you give the 790 a spin. By contrast, some robots arrive, make an initial impact and then are never seen or heard of again. Nor are their makers in some cases.

Thirdly, with this being a slight negative, if you’re price conscious or a bit strapped for cash, there are far more attractively priced models around.


Roomba 790 Review Conclusion

  • Unique Shape: Some people have described it as “flying saucer” shaped unit;
  • User Friendliness: A touch pad control, which can be used to give the robot directions if wanted;
  • Upgraded Cleaning Technology: An advanced cleaning head, which is claimed to be a big improvement on earlier models and which leads to the manufacturer’s claims of 98% removal of dirt and hair from surfaces;
  • State-of-the-art Sensors: Optical and acoustic sensors which enable the more comprehensive identification of dirt and dust particles;
  • Dual Capabilities: Multi floor capabilities for handling both carpets and hard floors;
  • Advanced Filtering: Improved filters removing dust and pollen particles from the air as small 0.3microns;
  • Low Impact Bumpers: Specially softened bumpers to prevent damage and scratching to furniture and other surfaces the robot comes into contact with;
  • Thorough Cleaning: What’s called persistent pass cleaning. In other words, the robot will sense when something is particularly dirty and go over it several times until it gets an acceptable result;
  • Hands Free Use: The docking station that the robot will return to automatically when it needs to recharge its battery;
  • Clear Interface: An automatic ‘bin full’ indicator, letting you know that it needs to be emptied!
