Overview of Roomba i6+
The Roomba i6+ is a high-end robotic vacuum that offers many of the same features as the i3+, but with a few additional ones. Like the i3+, the i6+ can also empty its own dustbin into a Clean Base Automatic Dirt Disposal system. However, the i6+ comes with a more advanced navigation system, making it better equipped to navigate around obstacles and clean in tight spaces.
The i6+ also comes with a more powerful motor, making it better equipped to handle tougher cleaning jobs. It has a 3-stage cleaning system that can tackle even the most stubborn dirt and debris, making it an excellent option for those with messy households.
Comparison of Roomba i3+ vs i6+
Now that we’ve looked at the individual features of each model, let’s compare the Roomba i3+ vs i6+ in more detail.
Cleaning Performance
Both the Roomba i3+ and Roomba i6+ are equipped with high-performance motors and cleaning systems that can tackle a range of surfaces. However, the i6+ has a more powerful motor and a 3-stage cleaning system, making it better equipped to handle tougher cleaning jobs. The i6+ is also better at tackling pet hair, making it an excellent option for pet owners.
Navigation System
While both models have advanced navigation systems, the i6+ is better equipped to navigate around obstacles and clean in tight spaces. This is because it has a more advanced mapping system that allows it to create a detailed map of your home, so it can clean more efficiently.
Dustbin Capacity
The Roomba i3+ and i6+ both come with a dustbin that can hold up to 0.5 liters of dirt and debris. However, the i3+ has a slight edge in this area, as it can empty its own dustbin into a Clean Base Automatic Dirt Disposal system. This means you won’t have to manually empty the dustbin after every cleaning cycle.
