The Roomba i1 and i3 are two popular robot vacuums produced by iRobot. Both models offer advanced features that make cleaning floors easier and more convenient. However, they have some differences in terms of design, cleaning performance, and other features. In this article, we will compare the Roomba i1 and i3 to help you decide which one is best for your needs.

Design
The Roomba i1 and Roomba i3 have similar designs, but there are some key differences. The i3 is slightly taller and wider than the i1, measuring 3.63 inches high and 13.34 inches in diameter, compared to the i1’s 3.6 inches and 13 inches, respectively. The i3 also has a more modern and streamlined appearance, with a black finish and a glossy top panel. In contrast, the i1 has a matte finish and a simpler, more utilitarian design.
Both models have the same layout of buttons and sensors on their top panels. They also have the same dustbin capacity of 0.5 liters. However, the i3 comes with a Clean Base Automatic Dirt Disposal, a dock that automatically empties the vacuum’s dustbin when it is full. The Clean Base can hold up to 60 days’ worth of dirt and debris, making it ideal for people who want to minimize the frequency of emptying their robot vacuum’s dustbin. The i1 does not come with a Clean Base, but it can be used with the Roomba i7+ Clean Base if desired.
Cleaning Performance
The Roomba i1 and i3 are both equipped with iRobot’s advanced cleaning technology, including a three-stage cleaning system, Dirt Detect sensors, and an Edge-Sweeping Brush. However, the i3 has some additional features that make it more effective at cleaning certain types of floors.
One of these features is the ability to detect carpets and automatically boost its suction power to clean them more thoroughly. The i3 also has a high-efficiency filter that captures 99% of allergens, pollen, and other particles as small as 10 microns. In contrast, the i1 has a standard filter that captures particles as small as 10 microns.
The Roomba i3 also comes with a Dual Multi-Surface Rubber Brush that is designed to handle both carpets and hard floors. This brush is more effective at picking up debris and pet hair than the i1’s standard brush. However, the i1 can be upgraded with a Dual Multi-Surface Rubber Brush if desired.
Features
In addition to its cleaning performance, the Roomba i3 has some additional features that make it more convenient to use than the i1. For example, the i3 can be controlled using the iRobot HOME app or through voice commands with Alexa or Google Assistant. The app allows you to schedule cleanings, view cleaning maps, and customize cleaning preferences.
The i3 also has a Recharge & Resume feature that allows it to automatically return to its dock to recharge when its battery is low. Once it is fully charged, it will resume cleaning where it left off. The i1 does not have this feature.
Here is a table comparing the features of the Roomba i1 and i3:
| Feature | Roomba i1 | Roomba i3 |
|---|---|---|
| Design | Matte finish, simpler design | Black finish, streamlined design |
| Dimensions | 3.6 inches high, 13 inches wide | 3.63 inches high, 13.34 inches wide |
| Dustbin capacity | 0.5 liters | 0.5 liters |
| Clean Base | Can be used with Roomba i7+ Clean Base | Includes Clean Base Automatic Dirt Disposal |
| Cleaning performance | 3-stage cleaning system, Dirt Detect sensors, Edge-Sweeping Brush, standard filter | 3-stage cleaning system, Dirt Detect sensors, Edge-Sweeping Brush, high-efficiency filter, Dual Multi-Surface Rubber Brush |
| Carpet detection | No | Yes |
| App control | Yes | Yes |
| Voice control | No | Alexa and Google Assistant |
| Recharge & Resume | No | Yes |
| Warranty | 1-year limited | 1-year limited |
As we can see from the table, the Roomba i3 has some additional features compared to the i1, such as a Clean Base, high-efficiency filter, carpet detection, and Recharge & Resume. These features make it more convenient and effective at cleaning floors. However, the i1 is still a great choice for people who want a reliable and effective robot vacuum at a more affordable price. Ultimately, the choice between the two models will depend on your specific needs and preferences.
