Picking a Roomba model can be hard because there are so many variants available. A Roomba comparison chart helps you choose between them, showing features and prices side by side On the official iRobot website you can mark boxes beside models and click to compare the selected directly here.
All Roomba models work with the iRobot app, where you can set functions and receive alerts about maintenance. This is one attribute that stays same across the whole range. Even so the differences between them easily become confsuing.
How to Choose the Right Roomba
A common overview mentions models like 675, 690, E5, I3+, I4+, I6+, I7+, S9+, J7+ and Combo J7+. The E5, 692 and 675 belong to the 600 series of iRobot, which is already a bit old. On the contrary, J7+ and S9+ belong to the top class. They both map the whole house and have automatic empty bins, but here end the similarities.
Older models use iAdapt 1.0 technology. New versions base on iAdapt 2.0, which allows you to avoid obstacles before hitting them. It is an important improvement.
In the 500 series the main difference is that the 530s do not have schedules, while the 560s have it.
Different Roomba types help to clean spaces of various size. For a big home it matters to choose a model with good mapping skills and long battery life. All present Roomba clean both carpet and wooden floors and pass between them, but some of them do that more better.
Double brushes of Roomba make a clear difference on thick carpets, even with low suction. Even basic E5 with 1700 Pa and two brushes give a much better result than competition with one brush. Even so camera and sensors can still be fooled by strange surfaces, like black carpet or mirror.
It is annoying that iRobot does not always ease comparisons. For example the 677 does not appear under the 600 series link on their website, and 600 series is not even among categories of the comparison page. There is no logical numbering system across models, which confuses customers.
Roomba models cover a wide price range and many features. For a reliable robot vacuum or combo with good software, broad support for parts and access at almost every price, iRobot Roomba series deserves attention. Researching the options using a comparison chart, choosing the right model, using it often and taking care of it well, like this everything willsucceed.
