iRobot Roomba 761 vs 770 vs 780 vs 790: Which To Get?

The 700 series vacs are quite similar to each other.

The 790 is the most advanced though with a Wireless Command Centre which allows you to control the Roomba from the command centre instead of a simple remote hand control like the 761, 770 and 780 have.

They all come with slightly different accessories too – including wall barriers, brushes and filters.

It’s worth checking out the 800 and 900 series Roombas before you buy though – you can check them out in this Roomba comparison guide.

Overall, we would say all robotic vacs are more light duty vacs for light pet hair pick up, and are good for automatic cleaning.

Because of the price of all these vacs – check the return policy and warranty conditions before you buy to protect your money investment.

If you have lots of pet hair, or thick or long pet hair around the house, you are better off getting a manual upright vac with more power, dust container capacity and ability to lift hairs specifically where you find them.

iRobot Roomba 761 vs 770 vs 780 vs 790: Differences

For the most part, the vacs are very similar. There are two main differences though:

Remotes, Wireless Command Center – the 761, 770 and 780 have a remote control. The 790 on the other hand has a WCC. This WCC makes initiating a cleaning, scheduling and steering Roomba even easier. Using radio frequency technology, you can now command the Roomba from any room in your house. Initiate a cleaning, pre-program your cleaning sessions or steer Roomba all from the sleek, lightweight Wireless Command Center.

Accessories – the 780 and 790 models come with an extra Wall Barrier, and and extra brush and filter set.

Drawbacks

There’s the new model 800 and 900 series Roombas out now, which have increased power and newer features an technology – they are better value for money

Not cheap

Can sometimes mark wooden room trim around the outside of the room if you don’t have the wall barrier set up and working properly

Some people prefer an electric upright vac which is more powerful, has a bigger capacity and cleans more thoroughly

More for lighter messes and lower amounts of dog hair – not as much for very heavy cleaning and large amounts of dog hair (or long hair)

For flatter surfaces and lower pile surfaces – may struggle on very thick/plush carpets, and steep changes in floor levels

 

Overall
