Summary : The Roomba 770 was designed with the sensitive in mind. Dual HEPA filters really clean your house. The result is spotless, clean air that you won’t react to.
Hate cleaning? Not comfortable with letting strangers into your house to do the job for you? Welcome to Roomba.
It’s a hands-off “vacuum”. Vacuum is in quotes because although it operates similarly to a one, the Roomba 770 has a whole host of other features that a standard vacuum can’t come close to touching. We’ll cover the good (and the bad) about it on this page – to view the official product page and current price, click here.
Say goodbye to sneezing
For some people, allergies are a slight annoyance. Then, there are the people who really suffer from allergies – watery, red eyes, constant sneezing and sniffling, etc.
And the worst part about them is the fact that they follow you everywhere. Those who are sensitive to allergies often find themselves sniffling and sneezing even when they’ve just recently cleaned their houses. What gives?
Here’s the answer: traditional vacuums will remove… let’s say, 90%+ of the grime on your floors. For most people, that’s enough. But the sensitive folks will still react to that tiny amount.
The Roomba 770 was designed with the sensitive in mind. Dual HEPA filters really clean your house – and not just 90% of it. The result is spotless, clean air that you won’t react to. One reviewer claims that this particular model “changed his life”. (It’s the last review on the Amazon page. Read it by clicking that link and scrolling down to the bottom of the page.)
More battery power means a faster clean
The Roomba 770 is fairly quiet for the most part, and unless you’re completely oblivious, you won’t run into it. But it’s still there. You want to enjoy the cleanliness of your house without having to constantly look at and listen to your “housekeeper” doing its thing.
The 700 series has a 50% longer battery life than the 600 series does. With this comes a slight price increase, but at the same time, it also means that your Roomba will likely be able to clean the house in one fell swoop. The charge lets the Roomba run for about two hours – this means that you can schedule it when you go run some errands, and when you get back, your house will be immaculate.
It’s almost like doing an errand while you’re doing other errands. Whoa.
If two hours doesn’t quite cut it, the Roomba will go to the docking station and charge itself. It will resume cleaning when it’s at 100% battery. So even if have a large house, you still don’t have to worry about doing any manual work.
The best surface area coverage
The 600 series from Roomba is slightly cheaper… but the machines are also slightly bigger. This isn’t a big deal until you start factoring in chairs, couches, etc. The smaller the opening, the smaller the Roomba has to be in order to clean underneath it.
The 770 is 13.9 inches x 13.9 inches x 3.4 inches. This is small enough to fit under most standard furniture, but it’s always a good idea to grab a tape measurer and see if it will fit. If it does, then you’ve found a model that will work on all areas of your house.
“Persistent Pass” cleaning for problem areas
Imagine that you’re using a traditional vacuum, and one area of your house is really dirty. Do you give a once-over? Probably not – you probably move the vacuum back and forth a few times to ensure that all of the dirt is removed, and not just some of it.
The Roomba 770 mimics that motion. First it detects the amount of dirt in a certain area, and if it’s more than usual, it goes into Persistent Pass mode. So no matter how dirty your house gets – whether it’s from animals, kids, etc. – the 770 is guaranteed to clean it all up.
This ensures that your floors are truly spotless, which means there isn’t anything left to give your sinuses trouble in the allergy department.
How it cleans the rest of the time
It’s important to note that the Roomba doesn’t just move around, constantly vacuuming. That would be incredibly annoying. It works by sweeping, then vacuuming… it’s sort of like a dustpan on steroids.
The 3-step cleaning process is below.
- The Roomba 770 calculates an area to sweep, and if that area is near a wall, it first removes debris from around the wall
- The next step is moving all of that debris into one big pile
- Finally, the Roomba 770 vacuums it up in one swift motion using AeroVac technology. If it’s using Persistent Pass, your Roomba will repeat steps 1-3 a few times.
It’s fairly quiet during steps one and two. Because the vacuum is so powerful, it does make a fair amount of noise during step three, but that noise is necessary to give you adequate power. Be wary of vacuums that claims to be “next to silent” – their working mechanisms are usually very weak, and they will leave behind grime that you’d rather they didn’t.
You also get…
- 2x “virtual walls” – you can use these to block the Roomba from entering an area, even if there isn’t anything physical (like a door) to stop it
- 1x flat brush cleaning tool
- 1x round brush cleaning tool
What others are saying
- Fairly quiet – one reviewer said that he could easily watch TV while the Roomba was doing its thing in the adjacent room
- Cured allergies – the same reviewer as above
- The best vacuum for pet hair!
- Easy to unpack and set up – can be done within 10 minutes if you really hurry
- It takes a strange path – sometimes it moves from room to room before completing either one, but reviewers are okay with that, because once the two hour charge is up, it’s already done cleaning
- Two hours of battery life is pretty darn good, but some models do have a longer
