Not everyone has the time or motivation to take 30-60 minutes vacuuming their entire apartment or household. iRobot took that problem and offered a solution called the Roomba, a vacuum that goes by itself.
The iRobot Roomba 770 is a good example of one of the smarter models on the market.
Roomba robotic vacuums freely roam around the room cleaning.
For the most part they don't need supervision or handling, which means you can leave for work or run errands while your Roomba does all the vacuuming for you.
In this Roomba 770 review, we'll go over its many features that may help towards your daily cleaning tasks along with points to consider before purchasing.
Roomba 770 Features & Specs
The basic function of the Roomba isn't too far from similar models or devices.
Its cleaning patterns consist of zigzag motions as it moves along the edges of walls and baseboards and uses the spot cleaning mode for local cleaning.
Compared to earlier Roomba models, the 770 capabilities are much more improved and powerful.
- It detects dirty areas with acoustic and optical sensors while the iAdapt system helps to guide it around furniture and either open or cozier layouts.
- The brushes quickly rotate to scoop up things like pet dander, dirt, food crumbs, and hair as it collects this debris in its dustbin.
- The HEPA filter makes sure dirt doesn't blow back out into the air making it ideal for those with allergies.
- The bristle brush allows for deeper and more effective cleaning which can prove to be useful against food bits stuck and dried to the ground or stubborn pet hair in the carpet.

Smart Cleaning Technology
The iAdapt Navigation feature uses many different sensors to help the Roomba navigate around your home and even adapt to different layouts of virtually any size, although it won't go up and down stairs.
You don't have to move around your furniture since it's able to maneuver around objects pretty well on its own, and it even cleans right up to wall edges and kickboards for more coverage.
Because of its slim design, the Roomba is able to get underneath most sofas, beds, and chairs.
To keep the Roomba out of rooms you don't need cleaned, it has two included virtual walls to help keep it contained to a specific room or area. These can prove useful if you don't want the Roomba wandering into a different room and draining its battery.
The dirt detection technology tracks spots that can often be missed, making for a more concentrated cleaning where it's needed the most.
If there's a particularly messy situation such as dried spaghetti bits from last night's messy dinner, the Roomba uses a persistent pass cleaning method (back and forth motion) to ensure the mess is thoroughly cleaned up.
Three Cleaning Modes
The Roomba 770 has three different cleaning modes depending on how quickly you need to clean or how much you need cleaned.
The quick clean mode cleans the room without worrying about spots that need more attention or if you accidentally spilled some dry cereal everywhere and need to clean it up.
The spot cleaning allows the Roomba to focus on a specific area and not the whole room.
The scheduled cleaning option allows you to preset your Roomba for cleaning at specific times, for example, right as you leave for work or right after dinner.
You can preset your Roomba up to seven times a week. This can be a useful feature if you have a strict routine during the day and can't be bothered to waste time.
To schedule the Roomba for cleaning, just turn it on, press "clock," enter a specific time and day, and then save your changes by pressing OK.
The soft touch bumper cushions make sure the Roomba doesn't scratch or mark up your furniture accidentally as it makes its way around objects.
These bumpers also determine what's soft or hard, allowing the Roomba to vacuum along walls without bumping into them and going under curtains or bed skirts, which often have lots of dust underneath because we tend to ignore these spots with regular vacuums.
How Does it Perform?

Floors & Carpet
The Roomba seems to be most effective on bare floors like wood or tile, which are surfaces that often collect the most debris.
It's best to keep any loose wires, shoelaces or rug tassels kept out of its path to prevent it from possibly getting jammed, which can damage the internal motor parts of the Roomba.
As for the Roomba on carpet, it doesn't do as well of a job compared to its performance on bare floors. It also may have a little trouble transitioning from bare floor to carpet if it's about an inch or higher.
If you're not home, it can either get stuck or move on in another direction, which can result in the Roomba draining its battery as it cleans over the same spots again.
Compared to its older 650 model, the noise of the 770 is no louder than a hairdryer, but the noise indicates that it has a powerful vacuum.

The dual HEPA filters help capture up to 99% of debris as small as 0.3 microns without letting it escape.
This makes it highly ideal for hardwood floors and carpet and means it won't recirculate dangerous particles back into the air, leaving your home allergen and dust-free which is good news if you have seasonal allergies.
As soon as the Roomba is done with an area, it will automatically go back to the charging dock which emits an infrared signal to guide it home.
Although, if it doesn't have a direct line of sight to the dock, its power may drain as it tries to find its way to the station.
Once the battery has completely run out of power, it can take up to three hours to fully charge it.
Because of this, it's best to charge your Roomba overnight if you immediately need to use it in the morning.
After it's fully charged, it has enough power to clean four fairly large rooms (runs up to an hour and a half). With proper care, the battery can work for hundreds of hours before needing to be replaced.

With the remote control, you can control the Roomba's vacuum patterns with your fingertips with the easy to use control pad.
It also allows access to all the Roomba's features from anywhere within the house at the touch of a button.
Unfortunately, like some Wi-Fi controlled models, you can't control the Roomba 770 with your smartphone.

To have the Roomba start cleaning, simply press the "Clean" button and press and hold it to turn it off. The other settings follow suit.
Three-Stage Cleaning System
The iRobot Roomba has a three-stage cleaning system to ensure a thorough and more detailed vacuum job.
First, the spinning edge brush captures and traps dust along the sides of the Roomba to make sure your wall edges are covered and cleaned.
Then, the two counter-rotating brushes guide things like loose cheerios or your pet's never-ending fur into the suction path of the vacuum's motor.
Finally, the Roomba sucks debris into the bin where air passes through the dual HEPA filters before being blown out from the exhaust.
Because the Roomba has been redesigned with an AeroVacTM Series 2 bin, it has even more added space for better coverage. This is especially handy if you have playful kids or messy pets that almost always leave something to clean up.
As the Roomba 770 manual emphasizes, keeping the brushes and bin clean are important in ensuring that the Roomba will work properly every time.
If they aren't maintained, the Roomba may push dirt around rather than pick it up, and the brushes may scratch your floor as a result of hardened materials it roamed over recently.
The worst-case scenario is that the Roomba also stops working completely which will render it useless and waste time and money.
The bin should be cleaned out after each use while the HEPA filter should be cleaned once per week (twice if you have pets) and replaced every two months.
The full bin sensors and front caster wheel need to be wiped clean once every couple of weeks and replaced every 12 months.
The side brushes and cliff sensors should be cleaned at least once a month and the extractors should be cleaned once every three to four months and replaced every 6-12 months.
These care frequencies should make your Roomba last longer and clean more efficiently.
The Roomba does come with some replacement parts such as an extra HEPA filter and an extra side brush. There's also a replacement kit that's available if you want to have replacement parts on hand for any unexpected repairs or accidents.
Who is the Roomba 770 For?
The Roomba is a nifty vacuuming device that cleans and roams around a room on its own hands-free. It's especially useful if you have little to no time to vacuum by hand.
If you work all day or are away from home a lot in general, you can simply turn on the Roomba with a simple push of a button and leave it to do its thing while you're gone.
It's also great to have if you can't push a vacuum around. Regular vacuums can be rather heavy, and being that the Roomba is somewhat small, it's also easy to clean out the dust bin.
On a regular day, all you have to do is pop it out and dump the debris in the trash can.

The iRobot Roomba can definitely hold its own and is one of the more impressive and newer Roomba models today.
If you're looking for something even fancier, you can opt for its sister model, the iRobot Roomba 880.
This Roomba is a more high-end vacuum and can be quite the investment, but the only real difference between it and the 770 is that it's able to navigate and clean up to three rooms at a time.
Other than that, it has similar features such as automatic self-charging, a scheduled cleaning option, a tangle-free debris extractor, a remote control, two virtual wall lighthouses, and a charging base.
While the Roomba 880 model performs well on bare floors and carpet, it's as noisy as the 770 and has the tendency to miss sections of a room during cleaning.
If you don't have the budget for the 880 model, you can also choose an older Roomba model such as the 650. It has seven preset cleanings or you can activate it for spot cleaning with a simple push of a button.
Unlike the 770 and 880, the 650 only comes with one virtual wall but it has a self-charging base and battery charger.
It has a rather high performance on hardwood floors and carpet and features a three-stage cleaning system, but it doesn't have a remote control like its sister models do.
Ultimately, the iRobot Roomba can serve to be a rather effective vacuum if you're way too busy to vacuum the house yourself.
You can save a lot of time as the iRobot Roomba 770 navigates around the room and cleans with advanced iAdapt Navigation and dirt detection.
It may be more beneficial if you live in an apartment compared to if you live in a house since it can take several charges for larger areas.
Whether you have hardwood floors, carpet, or large rugs, the Roomba can decently handle any surface but is most powerful on bare floors.
