problem

The iRobot app was originally designed for robot vacuums, so integrating a new air purifier required expanding the product without increasing complexity.

what i did

Designed the end-to-end purifier experience, including onboarding, dashboard, controls, analytics and linked automation.

outcome

A more unified ecosystem experience that improved setup, usability and multi-device interaction.

To comply with the NDA, limited information is shared the following case study ⚠️ This product is NOT in the market yet ⚠️

evolution

Evolution of the Air Purifier Experience

The product evolved from a standalone purifier app into a unified iRobot ecosystem.

Main challenges:Integrating a new device into an existing ecosystemSimplifying onboarding and setupDesigning consistent controls across productsMaking air-quality data easy to understand

Main challenges

‍• Integrating a new device into an existing ecosystem
‍• Simplifying onboarding and setup
‍• Designing consistent controls across products
‍• Making air-quality data easy to understand‍

Research & Insights

Research, benchmarking, user flows, wireframes and internal testing supported an iterative design process focused on clarity and usability.

User Interview

Internal and external interviews helped identify user expectations, pain points and mental models around air-purifier products.

Key Insights

‍• Users wanted a calm, simple interface
‍• One app for all home devices was expected
‍• Clear onboarding was essential
‍• Data had to be understandable at a glance
‍• Users wanted reassurance without constant monitoring

User research findings showing the need for a unified experience and simplified AQI information.

Flow & Structure

The experience was restructured to simplify setup, controls and navigation.

User flow for connecting the new air purifier and accessing real-time air-quality information

Early concepts explored different navigation patterns and purifier controls before refining the final structure.

Early wireframes used to validate structure, navigation and information hierarchy before applying visual design.

Product Iteration

Early versions exposed friction points that were refined in later iterations.

First Prototype (Alpha 1)

Initial design iteration highlighting usability friction and areas requiring simplification.

Final Prototype (Alpha 2)

Second prototype (Alpha 2) with refined navigation, clearer data hierarchy and improved visual consistency.

Visual Design System / Graphic & 3D Assets

Visual assets were designed to create a calm and consistent purifier experience.

Intro animation used to set the tone and visual personality before the login and sign-up screens.

As part of the visual system, I created a short intro motion that reinforces the purifier’s brand identity before users enter the login flow.

Usability Validation

Testing focused on AQI comprehension, controls and dashboard clarity.

Key findings

‍• Users preferred simpler data views
‍• Colour indicators improved comprehension
‍• Too much terminology caused friction

Final designs

Simplifying setup

Designed intuitive controls for scheduling, automation and device settings, helping users manage their purifier quickly with minimal effort.

Clarifying device status

Clear dashboards made air-quality data, filter health and product status easier to understand at a glance.

Making controls intuitive

A guided onboarding flow simplified account creation, device connection and first-time setup for new users.

linked cleaning (Combined Device Automation)

Connected purifier and robot vacuum behaviours to create a smarter ecosystem experience.

Why it matters

Users with both a robot and an air purifier expect one seamless ecosystem.

Before this feature, they had to manage devices independently.

What I designed

‍• A unified flow that connects cleaning cycles with air purification.
‍• Rules like “Start the purifier when cleaning finishes”.
‍• Simple controls for combined automation.
‍• Real-time synchronization between devices.

Impact

‍• Users felt more in control with less friction.
‍• Increased usage of both devices.
‍• Reduced need for manual adjustments.
‍• Contributed to the 20% increase in conversion rate.

Results & Impact

Business Impact

• +20% increase in conversion rate after redesign
• Higher adoption among robot owners using the purifier + robot combo
• Reduced customer-support tickets related to onboarding
• More cohesive multi-device experience inside the ecosystem
