Project overview
Following the acquisition of Aeris Cleantec by iRobot, the air purifier experience evolved to become part of the wider iRobot ecosystem. The objective was to create an intuitive mobile experience that helps users understand indoor air quality, control their devices and access meaningful environmental insights without unnecessary complexity.

The project focused on improving usability, simplifying information architecture and creating a more connected smart home experience through features such as Teaming, which enables air purifiers and robot vacuums to work together automatically.
Challenge
Air quality is often difficult for users to understand. Metrics such as particulate matter, allergens and pollutants can feel technical and overwhelming, especially for users who simply want to know whether the air in their home is healthy.

The challenge was to design an experience that transforms complex environmental data into clear and actionable information while providing effortless control over connected air purification devices.

Research & Insights
Methods
Conducted user interviews and usability testing throughout the design process.

Analysed how users monitored and interpreted air quality information.

Collaborated with stakeholders and product teams to align user needs with technical requirements.

Explored opportunities to strengthen the connection between air purification and robotic cleaning experiences.
Key findings
Users were more interested in understanding air quality than manually controlling the device.

Technical environmental data was often difficult to interpret.

Users preferred automated experiences over frequent manual adjustments.
Solution
The solution focused on making air quality information easier to understand while giving users full control over their devices through a clean and intuitive interface.

Complex environmental data was translated into meaningful insights, allowing users to monitor their home environment, adjust purifier settings and automate routines with confidence.

Key Decisions
Prioritising air quality visibility over device controls
Research and stakeholder discussions revealed that users cared more about understanding their indoor air quality than manually adjusting settings. The experience was designed to make air quality insights easier to access and interpret.
Simplifying purifier management through predefined modes
Rather than exposing advanced controls by default, the app relied on predefined modes such as Sleep, Fast and Manual to reduce complexity and support quicker decision-making.
Creating a connected ecosystem experience
The linked cleaning feature was designed to automatically trigger purification after cleaning sessions, reducing manual effort and reinforcing the value of the broader iRobot ecosystem.
Outcome
The final experience delivers a clearer and more accessible approach to air quality management while strengthening the connection between products across the iRobot ecosystem.

By simplifying complex environmental data and introducing intelligent automation through features such as Teaming, the app helps users maintain healthier homes with less effort and greater confidence.
