I just bought a new vacuum cleaner that claims to be dustless.

That sounds amazing! I've always wanted one of those.

Yeah, it really helps with my allergies since it doesn’t release any dust.

Definitely worth it if it keeps the air clean!

Root Explanation

Dustless → It is formed from "dust" (from Old English *dūst*, meaning fine particles of matter) and "-less" (meaning without). The word "dustless" means without dust or free from dust.

Memory Tip

Think of being 'without' ('-less') fine particles ('dust') — that's why dustless means free from dust.
