Handheld Vacuum Enhancement

I'm looking for an engineer or product designer to improve a handheld vacuum. The key improvement needed is the addition of a disposable bag liner.

Key requirements include:

- Design and integrate a disposable bag liner system.
- The liner should be easy to install and remove.
- Ensure the design maintains or enhances current suction power and battery life.

Ideal skills and experience:

- Expertise in vacuum design or similar appliances.
- Experience with disposable bag systems.
- Strong background in product development and prototyping.

Please provide examples of previous work and a detailed plan.
