iRobot ® Roomba 770 – Full Review


The Roomba 770 is one of the models released in the 700 series Roomba vacuum bots (Roomba 770, 780 and 790), and as Roomba bots go it is considered better than previous models in the 600 series and earlier 700 series, and comparable in some mannerisms to the most recent 800 series Roomba versions (Roomba 870 and Roomba 880).

The 770 Roomba automates vacuuming for the consumer, and allows the consumer to clean their floor surfaces conveniently without hassle with its functions being capable of employing commands, schedule cleaning sprees, and providing more of a hands-free robotic vacuum experience to the user.



How Does it Work?

The Roomba 770 iRobot vacuum features a dual Hepa filtration sequence that is said to help with airborne particles, dander, and dust that cause allergies. It also can be pre-programmed, commanded to clean certain areas by virtual walls, and scheduled on specific cleaning days and times.

The 770 Roomba consists of a pre-built in 3-stage cleaning process that breaks up, lifts, and extracts dirt from all types of floor surfaces. Its cleaning head includes a suspension system that can auto-adjust according to the texture and changes of a surface (ie. carpet, hardwood, tile, etc.)

Additionally, much like other versions of the Roombas, the 770 has a control panel, remote control, and docking station. It can be remotely controlled via the remote or by the simple press of a button.

The Roomba 770 also can recharge itself, detect when battery is running low, dock itself when finished cleaning, and will also notify you when the trash bin needs to be cleaned, if there are issues, when battery is in process of charging, needs to be charged, or is dead completely.




Customer Reviews & Feedback


When evaluating the iRobot Roomba 770 reviews on Amazon, we found that:

85% of 4-5 star ratings:
All but 15% of reviewers provided 4-5 star ratings for the Roomba 770 model. Out of them, what pleased buyers the most was that this Roomba performed as expected at picking up allergens, dirt and hair off variable floor surfaces. Users also reported that it navigated well, even on dark surfaces- and that it requires little effort to command, schedule, and let it do its job.


“I absolutely love my Roomba! I do not like to walk through my home a feel dirt on my feet. I ran him and was mortified at the amount of stuff that was picked up off of my floor! He cleans my hard wood floors in the main part of the house and the tile in the laundry room, pantry, and master bath. He also will clean the rugs I have in the living area, breakfast nook, entry ways, and bathrooms! I have very long hair and ‘Charlie’ picks it up with no problem…I just make sure that I use the cleaning tool that comes with the machine.”

“I adopted a Black Lab two years ago and have been drowning in black hair! I have to vacuum every day. My friend had this iRobot and I was extremely skeptical. I set it up and let it go and wow it did a wonderful job. It does not get into every crack and crevice. Very happy with it”

“I bought this for my wife for Christmas since she was complaining about not being able to sweep the floors enough. We don’t have any carpet or pets, but it sure does a great job on my wife’s long hair that seems to be everywhere around the house! Since our son and I have more sensitive allergies, I went with the higher grade model. I’m glad I did. All in all, I would definitely recommend one of these. It picks up a ton of stuff every time and is easy to clean out. You should be happy with the results.”

11% of 2-3 Star Ratings:
Reviewers and their ratings of 2-3 stars made up about 11% of consumers who purchased the Roomba 770. These ratings were given substantiation through consumer remarks about poor instructional guidance with the purchase, that the Roomba 770 works better on carpets than hardwood floors and it’s more a sweeper than vacuum, and that emptying the trash bin and cleaning out brushes were a detriment- even though it works well at cleaning floors.


“It needs to come with more detailed instructions on how to use it and how to clean and maintain it. I found the DVD and the written literature completely lacking. It cleans well, but there are so many things you could share about it to make it easier for the buyer. How would you like to buy a paint by numbers kit, only to find there are only a third of the numbers shown? ”
(By Kathy, Amazon Rating Given: 3 Stars)

“I have 2 dogs, which apparently shed more than I thought. I have to clean the vacuum frequently, at least every other run. I have it scheduled to run 6x week. It is nice to come home, see the sun shining through the window onto your dark wood floors and not see hair and stuff. A little expensive but definitely a time saver.”
(By Tamara Payne, Amazon Rating Given: 3 Stars)

“This is a sweeper, not a vacuum as advertised. I bought it for hard wood floors, and to clean pet areas. I find it works a lot better on my carpets, it picks up everything on them. It does like to eat cords, so I just make sure they are up when time to clean. Machine is not as loud as a vacuum but does make a good bit of noise. Over all it’s not what I expected for the price, but I will keep it for my carpets. ”

4% of 1 Star Ratings:

The poorest ratings are about 4% of consumers who found their experience with the Roomba 770 unpleasant. Most reviewers who rated the 770 with one star complained about faulty equipment (ie. wheels falling off, missing brushes in package, and other things.) Additionally, people remarked that this Roomba model is loud and DOES have issues with dark surfaces.


“Missing the brush in the package”
(By Dent, Amazon Rating Given: 1 Stars)

“Wheel falls off continuously. We have tried teflon tape on the axle, but after only 4 months of daily use, this should not be happening. We have hardwood floors with one area rug. Roomba does fine with changing from floor to rug and I don’t think the floors are abusive to this wheel! After paying $500+ for this vacuum cleaner, I’m pretty upset about this design flaw. I’ve contacted their customer service, but so far have not received a response. I love the idea of the Roomba, and it has saved me lots of work, but the one star is for the annoyance factor.”

It does a decent job of cleaning and according to ratings it picks up hair, reduces allergens, and performs just as claims predict.
