Feature Comparison

Mapping

Unlike robots that don’t have a map and move randomly until the battery runs out, Roomba navigates efficiently. It moves back and forth in straight lines methodically covering the cleaning area based on the map it generates.

Roomba i4 uses an iAdapt 2.0 sensor to map your home layout; the Roomba i8 uses a camera sensor. The camera suffers in dark rooms.

Roomba i4 cannot store maps in memory. Roomba i8 can store 10 different maps in memory.

Schedule activities.

The Roomba i4 only has basic scheduling features. You can only schedule it to work at a specific time and day of the week.

Roomba i8 has an advanced scheduling feature. After mapping, you can divide the map into separate regions and give each area a name. With this feature, you can schedule cleaning by area, no-go zone, selected room cleaning, schedule, etc.

Roomba i4 does not have a digital virtual wall creation feature but you can buy an additional virtual wall barrier to create a no-go zone.. meanwhile, Roomba i8 is equipped with a digital virtual wall creation feature that helps create a no-clean zone, Zoned cleaning.

Zoned cleaning: the robot cleans within a particular zone

No-Go zone: keeps the Roomba off some zones

Room cleaning: can be ordered (or scheduled) to clean in a certain room or two.

Controls

Roomba i8 can control it manually like a car radio.

If you need the device to go to a specific spot, you can use the app remote control and manage its movements by sending it where you want to. Also, with the «Target Point» option you can tap on the map, and the robot will go to that place. Much easier than using the remote control.

You can also control the two robot vacuums by setting voice prompts through Amazon Alexa Support and Google Assistant Assistant.

Activity tracking

When Roomba finishes cleaning, you can view the results in the cleaning history. Both cannot be tracked in real-time, you cannot see its location while the robot is vacuuming.
