Smart iQ Pro Sensing Technology
The CleanSense iQ+ features four intelligent sensors that optimize cleaning performance:

Figure 6: Overview of the four smart sensing technologies integrated into the vacuum cleaner.
- Edge Sensor: Detects walls and corners, automatically increasing suction by up to 2.5 times in Eco mode for thorough edge cleaning.

Figure 7: The edge sensor identifies walls and corners, boosting suction for effective cleaning.
- iQ Sensor: Automatically adjusts suction power based on the amount of debris detected. The display changes color to visually indicate the debris level (low, medium, high suction).

Figure 8: The iQ sensor dynamically adjusts suction and provides visual feedback on debris levels.
- Floor Sensor: Detects the floor type (hard floor or carpet) and automatically adjusts the brush roll speed for optimal cleaning on different surfaces.

Figure 9: The floor sensor automatically adapts brush roll speed for effective cleaning on various floor types.
- Light Sensor: In dark areas, the light sensor automatically brightens the headlights on the floor nozzle to illuminate hidden dust and debris.

Hybrid Power Clean Head
The unique Hybrid Power Clean head is designed to prevent hair tangles, making it ideal for homes with pets or long hair. It provides powerful suction for both flooring and carpets.

Maintenance
Emptying the Dust Cup
The auto-empty dock significantly reduces the need for frequent manual dust cup emptying. The dock's capacity is designed for approximately one month of debris, depending on usage and room conditions.
- When the vacuum is placed on the dock, it will automatically transfer collected debris to the dock's larger bin.
- To manually empty the handheld unit's dust cup, press the release button and empty contents into a trash bin.

Cleaning Filters and Brush Roll
Regular cleaning of filters and the brush roll is essential for maintaining optimal suction and performance.
- Dust Cup and Filters: The dust cup and internal filters are washable. Rinse them with cold water and allow them to air dry completely for at least 24 hours before reassembling.
- Brush Roll: Remove any hair or debris wrapped around the brush roll. The Hybrid Power Clean brush roll is designed to be anti-tangle, but occasional checks are recommended. The brush roll can also be rinsed with water if necessary.
