How to clean the length extension pipe
1. Separate the main body and the suction nozzle from the vacuum cleaner.
2. Wrap wet tissue or cleaning cloth around a long stick.
If there is no long stick, then wrap the handkerchief or mop pad with a line.
3. Extend the extension pipe and use it as a stick or let the line penetrate it to clean the inside of the extension pipe.
Repeat it on top/bottom when you clean it.
4. Never wash the length extension pipe with water.
The use of water may lead to fire or electric shock, or may damage the product.
