Vacuum Cleaner Handle Trap

In a cylinder vacuum cleaner, the vacuum is generated in the main body of the device. In front of that is usually a bag* which acts as a receptacle for dirt and an air filter. Attached to the bag is a long hose with a handle section on the end. Into this handle fits accessories, such as a brush attachment or longer tool with a wide head for floors. In the handle is often a sliding door. Many are confused as to what function this performs, but in my experience it is twofold. 1. To reduce the vacuum power temporarily if you're vacuuming something delicate. 2. to reduce the vacuum to make changing attachments easy. It's this general region of the handle I want to use.

In the handle we will have a "trap" operating similarly to the one under most sinks. The air will enter a clear polycarbonate cylinder and leave through a cage-like mesh structure, the holes should be large, >5mm, for minimal airflow restriction. The polycarbonate structure will be easy to unscrew and as an added bonus should have a magnet embedded in the wall such as to be inline with the intake flow. Now, if you vacuum up a coin, ring or screw etc. It will be trapped and easily visible**. You can open the little vacuum release door, unscrew the trap and retrieve your item. The cage-like structure should also stop any large objects like socks/pieces of plastic from making it all the way into the vacuum cleaner where it may block flow or be difficult to clear.

*Cyclonic devices do exist, but I'm resistant to gimmicky marketing. **at least at first until it gets all scratched up and dusty like a Dyson.
