iRobot Roomba 770 reviewOverview

We’ve mentioned over and over in many Roomba reviews that a number of Roomba cleaners share a lot of features. A very good example is Roomba 760 and 770. There are only a few thing that are different. One is the Dirt Detect technology. 770 has the Dirt Detect Series 2, which is a more advanced version. The other difference is a full bin indicator, which is distinctly found in Roomba 770. But the rest is the same. Both have the same dual HEPA filter, control panel, bin type, and debris they can work with. They also have on-board scheduler and don’t have room-to-room navigation (this is a feature of the 780 model). To simplify this iRobot Roomba 760 and 770 review, we’re going to talk about 770.

Detailed Review

Roomba 770 is actually pretty heavy at 8 pounds (though this isn’t the heaviest among the robots). Fortunately, there are plenty of functions that are already automated. It also includes a carrying handle, so you can comfortably transport this especially if you’re bring down from the stairs. Not all robots have carrying handles.

When it comes to cleaning, Roombas are always known to be generally excellent. The 770 model is no different. There’s the persistent pass cleaning system and iAdapt responsive technology. This means the robot vacuum cleaner passes through the same area multiple times in a back-and-forth motion to ensure all the dust and dirt are removed. They also work alongside with the more improved Dirt Detect technology, making sure no grime or debris is left to linger in the room. If you want to be sure the robot doesn’t go astray, you can put up the virtual walls. With its AeroVac Series 2 bin and advanced cleaning head, the robot can penetrate deeper into carpets and rugs, a job that is not easily done by its competitors. This is also the reason why 770 is a good vacuum to use for pet hairs. If there’s one major issue, it will be the maintenance of its parts. Its brush tends to collect hair; thus, you’re bound to spend a lot of time cleaning these brushes.

The robot still finds itself bumping into furniture and sometimes walls. Fortunately, there’s the molded soft-touch bumper to reduce the impact.

iRobot Roomba 770 is also equipped with a full bin indicator, a feature missing from its closest relative, 760. Further, there’s a pair of HEPA filters that trap as small as 0.3 microns of particles.

Like a lot of Roombas, this also comes with an onboard scheduler and self-charging home base. Nevertheless, the cleaner has already been enhanced to have a longer battery life.

User Comments

The Roomba 770 isn’t going to eliminate your need for a more powerful, traditional vacuum, but it is is certainly going to cut down on how often you have to run it.  There is something oddly satisfying to coming coming home and seeing the tracks in your carpeting that tell you the Roomba was out on patrol for dirt and you didn’t have to lift a finger to do it.

 I don’t think my carpets are dirty since it runs everyday, but it keeps picking up hair and dirt that I can’t see. My carpets look so clean and my kitchen floor is dirt free. I wish I would have bought one sooner.

So far so good.  It is great having a remote control and make the roomba goes where you need it. Bin fills a little too fast, but if you maintain your home clean that is not a problem. I am loving it.
