A comparison of the similarities and differences between the Roomba 780 and Roomba 880.

Are you interested in getting a top notch robot vacuum and are trying to decide between the Roomba 780 and the Roomba 880, however are a little unsure over their differences and basically which is the better option to go with (in terms of bang for buck)? Well if so, this comparison guide will definitely be able to help you out.

As you can see from the comparison table (just on the right), there is actually not too many significant differences between the Roomba 780 (700 series) and 880 (800 series), so why the price jump of more than $100?

AeroForce Cleaning System

Well there is one difference and that's the cleaning system on-board the 880, it is vastly more powerful and effective than the Roomba 780. The Aerofoce cleaning system in comparison to the 780 produces "up to 50% better cleaning" this is because it they have revamped all three independent components that work in unison to create an effective machine.

i) Tangle free extractors - act to gather up and break down debris and dirt from all floor types.

ii) Airflow Accelerator - adjusts to the floor type (tile, carpets, hard wood, laminate etc.) being cleaned and creates a sealed channel to allow for a more concentrated suction air flow, drawing in more pet hair and dirt etc.

iii) High Efficiency Vacuum - then finally a five times more powerful vacuum than the 780, gathering in more dirt, dust and pet hair from your floors.

Not mentioned in the table is that the 880 also has a 60 percent bigger bin capacity than the Roomba 780 too, so means less 'hands on maintenance'.

A lot of the remaining features remain the same though, they both still have the edge cleaning system to grab dirt from your skirting and walls (this is due to the spinning side brushes that you can see in videos with the Roombas in action) as well as the already mentioned self adjusting cleaner heads. They also have the HEPA filters integrated making it ideal for homes with allergy sufferers where they capture more than 99.9% of harmful bacteria from being expelled into your home's air supply whilst vacuuming.

Common Cleaning Features

You will notice they also have the dirt detect series 2 mechanism -- where the robot vacuums use optical and acoustic sensors to identify particularly dirty areas on your flooring, they will then use the persistent pass option. This will basically make the Roomba perform multiple passes (like you would with a standard vacuum cleaner) until it is clean.

Navigation

They also use the same navigation system, iAdapt responsive to formulate an efficient cleaning path that accounts for and avoids obstacles in the process. This being said the version that comes with the Roomba 880 is more up to date and basically more intelligent. You will notice I mentioned the Room to Room cleaning this refers to the virtual lighthouses that come with the Roomba 780 and 880, they allow a Roomba to finish up vacuuming one room and without interference (like other Roomba models without these lighthouses) to go on and start cleaning the next room.

Run Times

Another difference to note is the run time lengths. The Roomba 880 can run for about an extra 20 or so minutes in comparison to the Roomba 780, reaching the 2 hour mark. However, you will see that the Roombas have a really cool feature where they will automatically take themselves off to their docking stations when they are running low on power. If they half way through a job and are low on power, they will take themselves to a docking station, to get charged up and will return to the job in hand and start from where they left off.

Scheduling Program

Perhaps my favorite feature on both the 780 and 880 is the scheduling program. Where you can essentially set the robot vacuum to get cleaning whilst you're at work or on holiday, so you can pretty much turn up into your apartment/house with clean floors. Nothing quite beats that feeling.

Which to Buy the Roomba 780 or 880?

The only two differences you need to take note of when deciding which Roomba to buy is the difference in price of around $100 and the difference in cleaning performance. For me, if you are spending almost $600 for a robot vacuum, another $100 to get a vastly improved robot vacuum makes a lot of sense. But only you can really decide which is the best one to go for. What is for sure though, is the Roomba 880 is definitely the best robot vacuum around and you wouldn't be going too wrong with the Roomba 780 too (which is also a top, top quality vacuum).

If you are looking for a cheaper Roomba that still offers a decent performance I'd recommend either the Roomba 650 or Roomba 770.
