What it is:
This upgraded dust collection pipe offers the following enhancements over the previous version:
1. The inner walls of the pipe are smoother, reducing the likelihood of blockages and minimizing the occurrence of loud whistling when used with high-suction vacuum cleaners.
2. The pipe's color has been changed to semi-transparent, making it easier to detect any internal blockages.
Note:
To determine if your machine has been updated with the new version of the dust collection pipe, you can check whether the pipe is semi-transparent.
