What is a Roomba and Why Choose One in 2026?
Roomba, a name synonymous with robot vacuum cleaners, has been revolutionising home cleaning for over two decades. In 2026, the technology has advanced significantly. These autonomous cleaning machines are designed to take the chore of vacuuming off your hands, offering convenience, and freeing up your valuable time. Smart home integration is now seamless, with Roombas easily connecting to systems like Amazon Alexa and Google Assistant. Modern Roombas aren’t just about automation; they boast advanced features like smart mapping, obstacle avoidance, and even self-emptying bases. For busy households, pet owners, and anyone looking to maintain a consistently clean home with minimal effort, a Roomba is a worthwhile investment.
Understanding Roomba Model Numbers (2026 Guide)
iRobot’s Roomba naming system can be a little confusing, but understanding it is key to choosing the right model. Generally, higher numbers indicate more advanced features and performance. Here’s a breakdown:
- i Series (e.g., i7+, i3 EVO): Focuses on smart navigation and cleaning efficiency. The ‘i’ signifies intelligent mapping and cleaning.
- j Series (e.g., j7+): Builds upon the i Series with a stronger emphasis on obstacle avoidance and precise cleaning.
- s Series (e.g., s9+): The premium series, offering the most powerful suction, advanced cleaning technologies, and a focus on deep cleaning.
- Combo Series (e.g., Combo j9+): The latest series which combines vacuuming and mopping capabilities in one device.
- The ‘+’ Sign: This indicates that the model comes with a Clean Base Automatic Dirt Disposal system. This base automatically empties the robot’s dustbin, reducing maintenance and allowing for multiple cleaning cycles.
