Key Features

The Roomba 770 robot vacuum weighs roughly 8 pounds and is about 3.6 inches high. It’s definitely bigger than earlier iRobot models, but with size increase also comes power increase. It may have gotten a bit louder, but the noise emanating from this tiny robot vacuum is still subtle compared to traditional vacuums.

One of the significant improvement seen on the Roomba 770 from previous iRobot models is its sealed gearbox. In its early days, most Roombas were often sent off to repair shops because hair and dirt often snuck up to the gearbox making the vacuum useless.

Now, the gearbox is sealed and it’s also easier to clean and maintain. Its parts can also be dismantled quickly so you can clean each one of them easily. Here are some of the Roomba 770 key features:

  • Dual HEPA Filters: Integrated with dual HEPA filters, cleaning with the Roomba 770 means you won’t worry about dander, dust, and dirt to spread all over your room. iRobot has made sure it won’t escape the bin.
  • More Efficient Sensors: Its sensors are self-adjusting. It will detect dirt even if it’s under your furniture or bed. It can even detect dirt on the edges of your curtains.
  • Three Modes of Cleaning: With the 770’s three different cleaning modes – scheduled, spot, and cleaned – users can pre-set whether they want only a certain spot to be cleaned or the whole room.
  • Easy Scheduling: The Roomba will clean your whole house even before you return. You simply need to set the 770 depending on what time you want it to clean, which you can do up to seven days per week.
  • Vacuuming Bin: The Roomba 770 makes it easier for consumers to clean it. The problem with most vacuum cleaners is that hair sticks to the brush, leaving most users frustrated since they will have to take the brush off and pick the hairs one by one. With the 770, the vacuuming bin will pull hair off the brush and get rid of it straight to the bin.
  • Full Warranty: You can return the product if you’re not satisfied as long as it’s still within 30 days from purchase. The manufacturers will also return your money full.

Roomba 770 Review

The Roomba 770 is able to clean your house because of its algorithm-based method of cleaning, relying on its acoustic and optical sensors to spot dirt, dust, and debris, even on hard to reach surfaces.

With this algorithm based-cleaning method, the 770 will go through one area multiple times on one cleaning schedule. Many users have praised its human-like response to dirty spots, cementing the Roomba 770’s reputation as a robot vacuum one would most likely buy.

Carpet Cleaning

One of the great features the Roomba 770 has is its Persistent Path, which is the one responsible for the cleaning routes of the device. According to iRobot designers, the Persistent Path allows the vacuum to revisit a spot where it has detected dirt, cleaning it thoroughly even if you have the thickest of carpets.

The Roomba 770 also detects the furniture and other things atop your carpet such as cables and cords, as well as furniture legs, and avoids them completely. You don’t have to worry about getting things off of your carpet and return them back.

Hardfloor Cleaning

Earlier versions of iRobot Roombas had a hard time configuring the type of floor, especially when the device is placed first on the carpet before transitioning to hard floors. The Roomba 770 is much more advanced since it can now sense the change in surface whether it’s hardwood, linoleum, or tile.

Once the vacuum senses a change in surface, the rotating brushes at the center will stop and move on to the sides. Along with its Dirt Sensing feature, hard floors will be free of dust and dirt completely.

Pet Hair Removal

Pet owners usually have problems with traditional vacuums particularly when animal hair or fur is involved. The usual brushes found in most vacuums often needed to be cleaned once every two weeks, and the strands can be a pain to remove.

The Roomba 770, however, has solved this problem because its internal design won’t allow hair to stick to the brushes, resulting in unclogged gearboxes. Additionally, the Roomba 770 has cleaning tools including in the kit to make maintenance a whole lot easier.

Ease of Use

Any iRobot Roomba 770 review would comment how easy it is to use this particular robot vacuum. Its touchpad has all the controls you need to access the device’s features, but you can do so by using a remote control. Many find the remote control useful as it means you don’t have to catch the vacuum to configure it while it’s in the middle of cleaning.

Once it’s done, you don’t have to pick it up and return it to its spot either because it’s programmed to return to its charging dock after each cleaning cycle. In this case, the need for a remote is eliminated, too. It may be the most convenient cleaning gadget anyone could find.

Scheduled Cleaning

You can schedule the Roomba 770 to clean once per day, up to seven times per week. You simply have to set the date and the time of the day you want the device to do its job.

This means you can go as you please, even if it’s a long vacation. Since the vacuum charges itself, you can leave it and expect your house to be clean when you return.

Battery Performance/Charging

With proper care, the 770’s battery can last for hundreds of cleaning cycles before you need to replace it.

According to iRobot support, it would take about half an hour for the Roomba to be fully charged, and it will run for up to two hours.

To maintain the capacity of the battery, it’s important the battery is fully drained before charging it and keep it in a place where the device or the battery is not exposed to sunlight.


While there is an indicator that signals users that the Roomba is full, it is best to clear out the grime that builds up after the Roomba’s cleaning cycle. After emptying the dustbin, check the two filters inside before lodging it back in.

The filters are the ones catching the dust and needs replacement every two months or so, but to maintain it, it wouldn’t hurt to make additional care yourself. Clean those filters by tapping the lightly to knock out any remaining dirt.

Only then can you return it to the dustbin then back to the device. Filters that are overly dirty may need to be washed with water. However, make sure they’re completely dry before putting them back on. Otherwise, it will damage your Roomba.


As with all iRobot products, the Roomba 770 (excluding batteries) has a warranty period of one year from the date of purchase. The Roomba 770 also comes with a 30-day, money-back guarantee if ever a consumer finds the unit unsatisfactory. Replacement of the device may depend on the dealer or supplier.

Alternatives To Roomba 770

It’s a tough choice between two models given they’re from the same manufacturer. But starting from the price point, you’ll definitely save quite significant amount of money when you choose the 650.

However, it lacks the new features that the 770 has. For one, 770 has two virtual walls that keep the vacuum where it is supposed to stay.

Additionally, the HEPA filters are only found on the 770, which keeps the air clean while the robot is operating. The Roomba 650 lacks a remote control too, which the Roomba 770 has.

With the 870 model, the revolutionary AeroForce design was introduced. It offers 5 times more suction power than other Roomba models. However, the 770 still includes a base with a programmer just as the 870, meaning it’s not too hard to program the rooms you want to be cleaned and when you want it to.

In a way, the 770 and 860 are kind of similar, but the major difference is that the 860 has more battery life and is definitely more expensive. Both models have virtual walls and dual HEPA filters, making it a good choice for homeowners with intense allergies.


It may be hard to decide given all the alternatives available on the market these days. Aside from other brands, iRobot itself has a few models that make the deciding factor even more difficult. According to the above Roomba 770 review, pet owners will be first ones to be delighted.

The 770’s cleaning system is excellent when it comes to picking up dander and pet hair, plus the newly integrated HEPA filters will make sure the air is clean. Your hardwood floors won’t accumulate dust bunnies too, and pet hair in the carpet won’t pile up.

However, if the price is your ultimate driving factor, then you may find the 770 a bit expensive. The Roomba 650 may be ideally a better fit for you, which is a hundred bucks cheaper.

If you don’t mind spending the extra amount though, go for the 770 and you’ll have for yourself a highly intelligent and more responsive cleaning machine.
