Getting started
- Click the wand and a suitable cleaner head onto the main body, or attach a tool directly for handheld cleaning.
- Charge the machine using the supplied charger before its first use. Follow the dock installation leaflet if mounting the dock.
- Hold the trigger to clean and choose Powerful or MAX using the sliding control. Empty the bin before dust exceeds MAX.
Cleaning and maintenance
Wash filter A and filter B using their separate instructions. Let each dry completely for at least 24 hours before reinstalling. Follow the cleaner-head instructions before removing a brush bar.
Common questions
Why does the vacuum keep pulsing?
Check the bin, wand, cleaner head, and filters for restricted airflow. Stop the machine before inspecting or removing a blockage.
Which setting gives longer cleaning time?
Powerful mode is the everyday setting for longer cleaning. MAX provides stronger suction and uses the battery more quickly.
Can I wash the whole cleaner head?
Only wash the parts the guide identifies as washable. The main body and electrical components must stay out of water.
