1 Why is my vacuum making unusual sounds?
There are some occurrences while I'm using my handheld and it makes popping and whistling sounds. What could it mean?
Is this a good question?

If your Dyson handheld vacuum is making unusual noises, see the Dyson DC58 Makes Unusual Sounds problem page for possible problems and solutions.
The whistling is from the canister not being sealed effectively. Check that there is nothing stuck in the rubber seal that is preventing it from making a good seal. It is a good idea to wipe this area with a damp cloth once in a while to keep it free from dust or debris. Hope this helps.
