The logo is to convey "fast , wash , and clean" image for your company.

1. Fast: I highlighted the SHHS wording, to create a new onomatopoeia which represent to whoosh (咻 in Chinese, the pronunciation is shuuu, means fast is certain situation).
The lines inside the wording is a way to show the fast feeling.

2. Wash: The line itself also to wash (erase) away the wording, to create a washing feel.

3. Clean: I using light blue to represent a "cleaned" meaning compare with the dark blue which before wash, it became more clean after washed.
