The iRobot Roomba E5 is, in many ways, a conventional Roomba robot vacuum. It offers the features that most people expect from a Roomba, and these features are well-designed and well-integrated to the device.

When you’re using the Roomba E5, you’re probably going to be relying on your smartphone. Using your smartphone, you have access to the different cleaning settings, and you can also create a custom schedule for the vacuum. This lets you determine when the vacuum is on, and when it’s off. Along with that, you can turn the vacuum on and off, at any time, as long as you have Wi-Fi. It doesn’t matter where you are.

While the Roomba E5 moves across your floors, it uses a 3-Stage Cleaning System. This 3-Stage Cleaning System involves loosening up the dirt, dust, and debris that’s on the floor. Then, this dirt, dust, and debris is swept underneath the vacuum, into the main brush and suction channel. And then, it flows into the suction channel, and that’s it!

It’s not a complex cleaning system, but what it is, is a cleaning system that works exceptionally well! It makes vacuuming your floors easy for the Roomba E5, and ensures that everything that needs to be cleaned, is cleaned.

As for the suction power that the Roomba E5 offers, it’s decent. You won’t have any issues with vacuuming on hard floors. But, with carpets and rugs, it might not be quite as easy, simply because those floors require more suction power.
