Features

Automatic Recharge Function

The Roomba Plus 405 automatically returns to its AutoWash dock when the battery is low, ensuring it's always ready for the next cleaning session. This feature provides seamless, hands-free operation, keeping your home consistently clean without requiring manual intervention. It enhances convenience and efficiency.

Scheduled Cleaning Function

The Roomba Home App allows you to set specific times and days for the robot to clean, enabling you to program it to clean while you're at work or asleep. This ensures your floors are always clean without any effort, adding convenience and saving you valuable time. You can customize cleaning schedules for different days and rooms.

Virtual Wall Function

Through the Roomba Home App, you can create virtual boundaries to prevent the robot from entering certain areas of your home. This feature is useful for keeping the vacuum out of delicate areas, pet feeding zones, or rooms you don't want cleaned, providing greater control over the cleaning area and preventing unwanted access.

Carpet Boost Function

The Roomba Plus 405 automatically adjusts its suction power when it detects carpet, providing a deeper and more thorough clean. This ensures effective dirt and debris removal from carpets and rugs, leaving them looking their best. The carpet boost function optimizes cleaning performance on different floor types without manual adjustments.

Object Detection Function

The Roomba Plus 405 uses intelligent sensors to detect and avoid obstacles like furniture, shoes, and pet waste. This allows the robot to navigate around objects more efficiently, reducing the risk of bumping into things and getting stuck. The object detection function minimizes pre-cleaning preparation and ensures a smooth cleaning process.

Multi-Floor Mapping Function

The ClearView LiDAR technology allows the Roomba Plus 405 to store maps of up to 4 different floors in your home. The robot remembers the layout of each floor and cleans accordingly, eliminating the need to remap each floor every time you move the vacuum. This feature is ideal for multi-story homes, providing efficient and customized cleaning.
