Accessories Installation Diagram

2-in-1 Charging & Storage Mount Installation Diagram

The 2-in-1 charging & storage mount is an optional accessory. You can install it based on your needs.

1. The 2-in-1 charging & storage mount should be installed in a cool, dry place with an electrical outlet nearby. Prior to installing, ensure that there are no electrical wires or pipes in the space directly behind where the mount will be installed.
2. The bottom of the mounting template sticker should be level and at least 103cm from the ground, and its top should have at least 30cm* of clearance above it. (*30cm: Leave enough space just in case you may need to purchase the replaceable battery in the future.)
3. Use a power drill with an 8 mm drill bit to drill a hole into each hole marker on the mounting template sticker, then insert a wall plug into each hole.
4. Align the position holes on the mount with the holes on the wall. Fasten it to the wall with the included screws.
   

Charging

Fully charge the vacuum before using it for the first time.

Note: A full charge will take approx. 4 hours. Using Turbo Mode for a prolonged period will cause the battery to heat up, which increases charging time. Allow the vacuum to cool down for 30 minutes before charging it.
