The PowerFins brushroll provides continuous cleaning contact, digging deep into carpets and directly engaging hard floors for thorough cleaning without needing to switch brushrolls.
4.3 Using MultiFLEX Technology

Figure 4.2: The MultiFLEX wand bends at a joint, allowing the vacuum to easily reach and clean under low-lying furniture without requiring the user to bend down.
Press the MultiFLEX release button on the wand to bend it, allowing you to easily clean under furniture and other hard-to-reach areas. This feature also enables compact, freestanding storage.

Figure 4.4: The handheld vacuum can be detached from the wand and used with or without accessories to clean elevated surfaces, curtains, or tight spaces.
Detach the handheld vacuum from the wand for lightweight above-floor cleaning. Attach the dusting brush or crevice tool directly to the handheld vacuum or to the end of the wand for extended reach.
5. Maintenance
5.1 Emptying the Dust Cup

Figure 5.1: The XL dust cup features a CleanTouch Dirt Ejector, allowing for quick and hygienic emptying of debris directly into a trash bin without needing to touch the contents.
Empty the XL dust cup after each use or when debris reaches the MAX fill line. To empty, hold the dust cup over a trash bin and press the CleanTouch Dirt Ejector button to release the bottom flap.
5.2 Cleaning the Brushroll

The PowerFins brushroll is self-cleaning, designed to prevent hair wrap. Periodically inspect the brushroll for any remaining debris or blockages. If necessary, use scissors to carefully cut away any tangled hair.
5.3 Cleaning Filters
Regularly clean the foam and felt filters to maintain optimal suction. Rinse filters with cold water only. Allow filters to air-dry completely for at least 24 hours before reinstalling them. Do not use a hairdryer or other heating methods.
- Pre-Motor Filters (Foam & Felt): Located inside the dust cup assembly. Rinse every month.
- Post-Motor HEPA Filter: Located at the base of the handheld vacuum. Rinse once a year.
