Customer Reviews

Roomba 770 Robotic Vacuum is rated 4.4 out of 5 by 193.
Rated 4 out of 5 by from Eventually loved it! I had been coveting a Roomba for several years as I had heard nothing but praises. When we got hardwood floors throughout I convinced my husband NOW was the time to take the Roomba plunge. at first I was very disappointed! It was missing alot of dog hair around the edges of area rugs and in certain areas. By trial and error I have discovered the answers for us at least. 1) Schedule it to run EVERYday if you have a pet(s). 2) Don't overwhelm it by defining too large an area.We blocked the sunroom and left the kitchen, dining area,living room and breakfast area.By the way I am happy to clean the bin daily to get the results! (Very little white dog hair on my hardwood floors)

Rated 5 out of 5 by from Incremental update - excellent vacuum I have had my new Roomba 770 (my 4th Roomba) for about 2-3 weeks. So far, quite happy with it. Caveat: I don't use it for scheduling or room-to-room navigation. I plunk it down and let it vacuum in one area at a time. Compared to my old Roomba 530 that experienced multiple organ system failure from overuse, I find that: 1. Noise level slightly but significantly less (maybe my old, tired 530 was getting noisy, though). 2. The back-and-forth over dirty areas was disconcerting at first, but effective. 3. Picks up debris at about twice the pace of the 530, much better at cleaning. And this with a HEPA filter! Good for those with allergies or asthma. 4. With fluffy cat fur, the "bin full indicator" comes on long before it's really necessary to empty it, so I ignore it. Cleaning the sensors with a paper towel when cleaning out the bin seems to help some. 5. Multiple versions of Roomba (since it first came out) used to leave debris along the edges of carpets. I would clean up after Roomba with a Dyson dustbuster along the edges of carpets. Well, whether due to the increased vacuuming efficiency, or the back-and-forth with dirt detect, or both, this is much less of a problem. In fact, I don't have to use the dustbuster any more. 5. The bearings are now in large yellow cups designed to keep debris out of the bearings. Seems to help, but I still find cat fur in there a bit, but much less than before. (But not dog fur for some reason - maybe cat fur has magic penetrating properties, derived from cats who walk through walls, cf Robert Heinlein.) One great side effect of this design: when you accidentally drop the bearing in the trash, you can actually FIND it! 6. The design with cylinders around the square brush drive sockets actually does a great job of keeping debris out of the cracks there - minimal cat fur there. This was a failure mode of earlier brush decks. 7. Roomba is now stronger. It can go over some obstacles (e.g., the 3/4" high plank on the bottom of our Stickley Harvey Ellis Writing Desk) that the 530 would get stuck on. 8. The battery life is great. Better even than an aftermarket high-capacity battery I got for my Roomba 530. 9. Roomba 770 seems heavier than the 530. But the handle is a better design - very comfortable to the hand, balances Roomba nicely. 10. One final tip: the best tool for getting cat fur wrapped around the ends of the brushes is a pair of splinter tweezers, recommend getting a pair. Bottom line: a winner. It is a great vacuum that will keep your floors clean, efficiently and easily.

Rated 5 out of 5 by from Very satisfied customer I love my new Roomba. It has come a long way since my first Discovery series which was fine except I gave up using it due to kids and ferret trying to ride it. :) My kids are now grown and Im down to a husband and small black Pomerainian (lots of hair). I have a larger new house and my floors are mostly all tile. I bought it because of health problems and am not able to vacuum the whole house everyday. I was amazed at how much it picked up the first time I used it because I had just vacuumed the day before. It runs from room to room for a long time and its very cool how it senses and slows down before touching walls and furniture. It recharges fast, after the first initial charge. Now I can keep up with the other cleaning chores. I am thrilled! I remember I used to hate cleaning the bin and brushes on my old model but this one is so easy and fast. I empty it every day just to see how much is on my floor in one day. WORKS GREAT for my needs. It does really well on regular wall to wall carpeting and my small area rugs, but I have two larger area rugs that are thick and have textured swirls, and the little guy gets caught in the middle of them. But it still saves me a lot of work. I would recommend this to anyone that would like clean floors but can't or doesn't have time to do them everyday. I just wish the extras, e.g., virtual walls, lighthouses, weren't so expensive. Soon as I get some extra money I will be checking out the Scooba!!! I'm also waiting for a robot that could dust and clean bathrooms. :) THANK YOU iROBOT for making life a little easier.

Rated 5 out of 5 by from Skeptic -- completely impressed Set it to run 6x a week, because my cat sheds and the hair is extremely visible on dark hardwood floors. She also tracks liter outside of the liter box. Every day I come home from work and feel like someone has cleaned my house. It has no problem going from the living room/dining room/bathroom (hardwood floors) & bedroom (carpet). The one thing to note is you have to stay up on keeping it clean (emptying the bin) and cleaning the brushes, etc. The included tools to do so are a great addition.

Rated 5 out of 5 by from Sanity Saver When I replaced all the carpet in the house with tile, I thought I was going to go insane with dog hair floating in the air. With no carpet, it had nothing to which it could attach. I had seen the Roomba various places, and my neighbor had received one for Christmas and loved it, so I started to do my research. I picked the 770, and I love it! If I ran it any more I would be accused of Roomba abuse! I have named mine Walt, because it does an awkward type of waltz like I do. The only thing it does not do is climb walls and dust blinds, but we are working on those tricks! Seriously, yes the bin is small and will fill quickly, but if you run it regularly this is not a problem. Best of all, no more dog hair floating!

Rated 5 out of 5 by from I am in love I am in love with my Roomba. I am 65 years old, have a full time job, commute about 2.5 hours a day and have 3 indoor pets. I run "Alice" about 3-4 times a week. I can come home, relax and let her clean away. Frees up my weekends so I don't spend them cleaning. Also saves me money because I don't have to hire a maid to come in once a week to clean. Love it, love it!!!

Rated 4 out of 5 by from really amazing tech We have 3000sqft of hardwood floors that my Love would spend an hour or more a day cleaning. With two cats I knew there had to be a better way. I did my research and ordered a new 700. BEST THING EVER! Not only does it save us time it cleans better! Really wish I had ordered one years ago. We will always have a Roomba.

Rated 5 out of 5 by from My Roomba Rosie Ibot the BEST!!! I wrote a review in January when I first purchased my ibot. My idea was to use her as a supplement cleaner in-between my main vacuuming That has changed. She is my main all the time cleaner. I use my big, heavy bulky vacuum in between if I need it but I usually don't. I absolutely love my Roomba Rosie Ibot and my granddaughter who put all those good job stickers on her still talks to her. What a great invention. If you are reading this review please try it out. You will be so pleased. It is a time saver and keeps our house clean. I can spend more time with my granddaughters and less on cleaning. I truly wish it was around when my sons were growing up. All the hours cleaning took away from just being with them and they grow up so fast. Please forgive my chatting on and on.
