Roomba 770 Vs 780

In this article, we’ll look at Roomba 770 Vs 780. How are these models similar and where do they differ?

Comparing Roomba 770 To 780

Where They Are Similar

When comparing the iRobot Roomba 770 Vs 780, it is important to note how they are similar. Both units have a 3-stage cleaning head, though this is comparable to a conventional vacuum cleaner. Both of them have a HEPA air filter whose replacements cost $30 to $40 when you buy the Roomba 700 series replenishment kit. Both units have the same dirt detector, have the ability to schedule when the unit will clean and a full bin indicator. You get the same round and flat cleaning tools. Both Roomba models come with a remote. Yes, this vacuum cleaner has a remote control. This is in addition to the touchpad control.

The entire 700 series has better software so that the robot vacuum maximizes its cleaning routine while minimizing the drain on the battery. And both models have better sensors so that they don’t get stuck under your recliner. The 700 generation of Roombas has cliff detection so it won’t fall down the stairs or get stuck after falling down the drop down into the living room. Both models are smarter than their predecessors and less likely to get stuck under furniture.

Pros of Roomba 770

• Roomba 770 is cheaper than the model 780. Roomba 770 is routinely available for $500 new.

• The model 770 comes with a 12 month warranty for the vacuum and a six month warranty for the battery. In contrast, Roombas in general last about a year and a half to two years with heavy use.

• Like all Roombas, you’ll have fewer problems with dust bunnies as long as they are hiding behind the furniture.

• It works great on a tile floor, hardwood floors, concrete and low pile carpets.

Cons of Roomba 770

• While the Roomba 700 series is probably the most intelligent vacuum cleaner you’ve ever had (perhaps, including the kids who supposedly vacuum the floor), it often errors out when it encounters dark and light patterned rugs. The problem is worse with black and white patterns but has been reported with brown mottled carpets, too. And you can’t turn off the cliff sensor that thinks the strips on the floor are a cliff.

• This model of Roomba does do a good job of getting back to the charger as the battery starts to run out. However, it frequently stops at that point, not recognizing it hasn’t finished vacuuming the house.

Pros of Roomba 780

• The 780 model has two virtual wall lighthouses, a modest improvement over the 2 virtual walls the model 770 has. The virtual wall lighthouses keep the Roomba in one room until it is considered thoroughly clean before sending it to the next room.

• The 780 model is easy to operate.

• The iRobot Roomba 780 has dual filters and sturdier cleaning heads to pick up pet hair, though it is just as good as the 770 on dirt and small debris.

• One caveat though is that very long pet hair can tangle up the axis. So enjoy the Roomba if you have a Chihuahua, short haired cat or pug. The Roomba may fail if you’ve got a briard or golden retriever shedding over the summer. Or spot vacuum the worst of the dog hair before letting the Roomba loose.

Cons of Roomba 780

• Roomba 780 costs around $600. If you want to save money, you can find it on sale for about $575. There are few used units on the market because it came out in 2012, and the used ones are still over $500 through most reputable online dealers. For the higher price, you get an extra set of brushes.

• The virtual wall lighthouses are useful, but the package doesn’t include 2 C batteries for them.

• When the Roomba has picked up a lot of pet hair, it may start to send the pet hair airborne.

Observations

The iRobot Roomba works best when the house is clutterless. It can navigate around obstacles like shoes and toys left on the floor, but it doesn’t do a good job cleaning the floor if you haven’t first picked it up. Be careful to keep doors open in a way that the Roomba can’t trap itself in the room. If it goes along the wall and pushes the door shut, it can’t get out. Then it may cycle over the same section of carpet or strain to come out, wearing out the carpet.

The Roomba has to be sent back to the manufacturer or an authorized repair shop to get repaired, even for battery problems. If you think you’ll be wearing out the Roomba because you have a large house or pets that shed prodigiously, you might be better off getting two or three Roombas, each for a different section of the house. The up front cost is higher, but the wear and tear on each unit and odds of breakdown go down. Don’t try getting third party bumpers for the Roomba, they tend to cause navigation problems.
