### conclusions v0.2
General assembly and airflow are working well, but the fine dust separation needs fine tuning. Especially when compared with the reference vacuum, the secondary cyclone is noticeably worse and lets a lot of fine particles through, which should be separated at the second stage. We've used very fine construction dust as a test, which is the worst case and generally not recommended for consumer vacuums but gives a good indication for the performance comparison as it leaves visible traces.

# take aways and next steps for v1 development

- [ ] static charge of the fine dust is currently an issue
- [ ] fine dust seperation in the secondary cyclone needs optimization (also visible in the sim)
- [ ] the filter should be easily accessible for cleaning
- [ ] the ratio between the small dust and main chambre should be considered based on the amount or small dust particles common in household applications
- [ ] the airflow seperation in the main chambre should be considerted further
- [ ] the small cyclone count thats neccessary for optimal airflow should be considered
- [ ] the emptying of the dust bin shoulbe be easy
- [ ] the flow path of the air in the secondary cyclone inlet could be optimized
- [ ] the option of a hepa filter should be there

# Cyclonev0.1 Simulation

Fine dust cyclones working as expected

Inflow is currently going directly into the fine dust cyclones which is not ideal

Mid three cyclones see most of the airflow which makes the consideration of their inflow more important, also a better distribution would be preferable

The dominance of the middle cyclones is visible even further on top

Another perspective of the inflow going mostly into the fine dust cyclones instead of the main chambre
