iRobot Roomba 770 Review PROS & CONS – Pet Robotic Vacuum
The iRobot Roomba 770 robotic vacuum cleaner is another model in Roomba series. It is bigger than earlier version and definitely more powerful.
Early Roombas versions had repair issue problem where dirt and hair could get in gearbox and make robot vacuums unusable.
Luckily that is not problem anymore as iRobots latest Roomba series of vacuum cleaners use sealed gearbox. Brushes, squeegees, and filters are easily removed so it is easier to clean them.
According to iRobot the Roomba 770 is smarter, powerful, has improved dirt detection, a larger dirt bin and longer battery life than previous models.
iRobot Roomba 770 Review
The iRobot Roomba 770 vacuum cleaning robot for pets and allergies does all the work for you. The sweeping and vacuuming is done with a touch of a button. The Roomba will collect all the dirt and debris from carpet, hardwood, tile and all types of floors.
Most important part of any vacuum cleaner is its dust bin. Of course, traditional vacuum cleaners have bigger dust bin and thus can collect more impurities.
But iRobot is actively working on that field and capacity of Roomba robotic vacuum cleaners series is providing redesigned dust bin with more space. The 770 is no exception.
The iRobot Roomba 770 vacuum allows pet owners to keep up with their pets by removing pet’s hair off their floor over and over again without ever getting tired or complaining.
Allergy sufferers will appreciate this because it has HEPA filtration. Dual HEPA filter captures dust particles. Many robotic vacuums pick up dust and dirt, but then it re-circulates back out the vacuum into the room. Roomba will capture the dust and will not let the dust escape back into your home.
Roomba 770 has a 3-stage cleaning system. The 3-stage cleaning system lifts deep dirt from carpets, tiles, linoleum and hardwood flooring.
The iRobot Roomba has a spinning side brush that offers cleaning along wall edges. It will get all those dust bunnies that gather at the edges of your floor and walls.
The counter-rotating brushes perform like a broom and dust pan picking up and sweeping at the same time. The vacuum will suck all this dirt and dust into the canister for removing.
The Roomba 770 vacuumcomes with a self-adjusting cleaning head suspension. This allows Roomba model 770 to go from carpet to hardwood floors without any problems or adjusting. It will self-adjust itself.
It is the perfect vacuum for homes with pets or allergy suffers. iRobot Roomba model 770 pet robotic vacuum comes with AeroVAc Series 2 Technology. This technology is designed to remove pet hair, pet dander, hair, dirt and dust from carpets and floors.
The iRobot Roomba 770 pet vacuum comes with an improved dirt detection system called Dirt Detect Series 2. Thanks to this technology Roomba 770 finds dirtier areas of the floor so it can clean it more throughly.
How iRobot Roomba 770 Vacuum Works?
The Roomba 770 stands approximately 3.6 inches high and weights 8.4 pounds. Very important component for any robotic vacuum is the dust bin. Larger, more traditional handheld vacuums offer far more capacity than robotic vacuum cleaners.
But iRobot has redesigned the bin and added space. The iRobot Roomba 770 pet robotic vacuum is no exception. It uses a single, removable chamber with more capacity than ever on a Roomba.
Since Roomba is a robot that cleans on its own, dirt detection system is a critical tool. iRobot uses a proprietary cleaning algorithm to drive the Roomba.
That being said, I was surprised how much it actually picks up when its done.
It does a pretty good job at maneuvering throughout the house. I was a bit worried about it getting stuck on things, but in my experiences the only thing to watch out for is thin cords and blind strings laying on the floor. – Buyer
It’s one of the reasons its cleaning path looks so haphazard. There is a method to the madness, though. That algorithm works in concert with a variety of dirt sensors. In addition to acoustic sensors that actually hear the dirt as it hits the machine, Roomba 770 now has optical sensors to see it as well.
When the Roomba detects a particularly grimy spot on hard floor or carpet, it begins an aggressive back and forth vacuuming motion. That is the way human would do it. iRobot calls this “Persistent Path” cleaning.
Cleaning path of Roomba 770 may look little strange to you. Dont worry, that is how it is supposed to work. Roomba can manage rooms and homes of any size. Though it cannot go up and down stairs.
There is no robotic vacuum cleaner who can clean stairs and I doubt there will ever be one. It comes with a docking station/charging base and will return to it on its own when it’s running low on battery.
iRobot Roomba 770 pet robotic vacuum comes with a remote control, which you can use to start the Roomba cleaning or even guide it to a certain spot and control its cleaning pattern.
It’s also easy to use Roomba’s on-board controls. Over the years, Roomba’s interface and controls have remained very simple and straightforward.
There’s still a large Clean button in the center and just a handful of buttons to control the on-screen. iRobot integrates anti-tangle technology, which is supposed to prevent the Roomba from getting stuck on rug tassels, strings and wires.
Despite anti-tangle technology iRobot Roomba 770 pet robotic vacuum will often get stucked. It is good to remove any objects that could cause iRobot Roomba 770 vacuum to stuck in room you intend to use it.
Roomba’s ability to detect other objects and stairs and work around these obstacles is remarkable. As vacuums go, the Roomba 770 does a good job of cleaning up most debris. About 90% will be vacuumed.
It’ll take about 3 hours to fully charge. iRobot recommends to keep it on the charging base all the time to maintain its charge and maximize run time.
If you’re not going to use it for an extended period then take it off the charger and store it. The light on top of the robot will turn yellow if battery is low and goes back to green if there is still a lot left.
The virtual walls though do not have any indicators that’ll let you know if batteries are running low. iRobot Roomba 770 pet vacuum will run about 90-minutes on a full charge.
iRobot Roomba 770 Floor Cleaning
It does great job on bare floors such as hardwood, tile and linoleum. Motorized brush and edge brush will pick up most of the dust and pet hair on this surface. All potential hazards like wires, rug tassels or spilled liquid must be cleared out.
It does have a penchant for getting tangled up with wires and when it gets stuck it has to be manually dislodged. Don’t expect deep cleaning performance on carpets. But it’ll still do a good job on maintenance clean-ups.

iRobot Roomba 770 is smarter, more powerful, has improved dirt detection, a larger dirt bin and longer battery life than previous models.
If you have thick rugs the Roomba 770 might not be able to go over it. It’ll either get stuck trying to or just move in another direction. For rugs with tassels, vacuum these separately because those tassels may get stuck in-between the two brushes underneath.
If strings or wires get in-between the brushes, it has an anti-tangle system that automatically shuts off and spins in reverse to free itself. Also if you have a really dark rug or carpet, the cliff detection sensors might think that it’s an open space and not go over to clean it.
Pet owners will mostly benefit from iRobot Roomba 770 pet robotic vacuum. Take note that like in all vacuums with motorized brushes, brushes need to be cleaned at least once every two weeks.
Fortunately Roomba 770 cleaner comes with a brush cleaning tool that will help in removing pet hair stuck on the motorized brush.
iRobot Roomba 770 comes with its docking station which is used for docking and charging the cleaner. Robotic Roomba 770 cleaner will go to charge automatically every time its battery becomes low.
The battery life, before replacement battery needed, should be 2 years or more.The Roomba’s battery is user replaceable and a new cell will cost you between $50 and $70.
Even though sometimes it may seem your rug, carpet, floor doesn’t look very dirty, when you pick Roomba and remove its bin you will more than often see substantial amount of dirt.
You can also schedule Roomba 770 when it should start vacuuming. There were several buyers who reported that sometimes Roomba 770 lost it data and time settings. Then it is needed to restart it and problem should be solved.

Buyer Reviews
–Most buyers are satisfied with cleaning performance. The biggest pro is the hands-free approach. Just schedule it and let it do its thing.
–It is capable of cleaning multiple rooms and reach areas under the bed and table but it will have some difficulty going back to its docking station to recharge if there are objects on its way.Make sure that you move everything away when it’s time to clean.
–Some buyers complain that it seemed not to know where it was going, often in moving in a random pattern (thus missing some spots according to some), bumping in furniture that resulted in some marks or getting stuck somewhere in the room.
–A great suggestion by people was to put rubber padding around it so that it won’t scratch any of your furniture.
–Other complains mentioned that it had trouble going back to its base, sometimes bumping the charging base out of its position and running out of battery trying to go back. One solution for this is to make sure that there isn’t any obstruction around the charging base.
–Clear anything that’s in the way like wires.

iRobot Roomba 770 Robotic Vacuum Conclusion
This robotic vacuum is great for people who really don’t have time to vacuum their floors on their own and would want a helper to do this task for them.
People with allergies should also give this a close look because of it is equipped with 2 HEPA filters that keep most allergens in the dirt canister and out of the atmosphere.
We vacuum with the big vac about once a week and this thing keeps everything in the interim looking great.
One big benefit is that it goes under furniture that we normally have to move to clean once or twice a year. It is great for going under beds that you very rarely get to because it is a real project to move especially the king size beds! – Buyer
Take note that since this is a robot, you’ll have to do your part to make sure that it will do its job. That means clearing the clutter around the room, remove any spilled drinks, wires, thick rugs, toys, bowls, etc.
It won’t clean stairs or really dark rugs but aside from that it works really well. The Roomba 770 is little bit expensive compared with some traditional vacuums.
If you’re going to go the automated cleaning route, you might as well get something that truly knows its way around dirt and your home. A standard vacuum will save you money, but not your precious time, and isn’t time money?
While that is great robotic vacuum cleaner I think that it deserves 4 stars.
I bought for my parents iRobot roomba 770 and can confirm that it is nice little cleaner to have.
iRobot Roomba 770 is great model and one of our favorites.
Good information indeed.
I purchased this vacuum specially for my wife, since she seems like she could never get ahead of the cat hair balls all year round. She loves it so much. I personally recommend that It is truly amazing how close it cleans to the walls. The sensors are really amazing.
Thank you for review and experience Hasan.
