Setup
1. Unboxing and Initial Placement

2. Charging the Robot
Place the Roomba robot onto the Clean Base. The light ring around the CLEAN button will pulse white to indicate charging. Allow the robot to fully charge before its first cleaning mission.
3. iRobot Home App Setup and Smart Mapping
Download the iRobot Home App from your device's app store. Follow the in-app instructions to connect your Roomba to your home Wi-Fi network. The app allows you to customize cleaning schedules, view cleaning maps, and define specific cleaning zones using Smart Mapping technology.

Maintenance
Regular maintenance is crucial for the optimal performance and longevity of your Roomba i3+ EVO.
1. Clean Base Automatic Dirt Disposal
The Clean Base automatically empties the robot's bin into a sealed bag, holding up to 60 days of dirt, dust, and debris. Replace the dirt disposal bag when full.

2. Cleaning Brushes and Filter
Regularly check and clean the Dual Multi-Surface Rubber Brushes and the Edge-Sweeping Brush to remove tangled hair and debris. The high-efficiency filter should also be cleaned periodically and replaced as needed to maintain suction power.
