Is the word sujos the same in Brazilian and European Portuguese?

Yes

The meaning, grammar, and spelling of "sujos" are identical in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, the final "o" is typically pronounced as a clear [u] sound, and the vowels are generally more open and resonant. In Continental Portuguese, the final "o" is often heavily reduced, sounding like a very short, nearly swallowed [u], and unstressed vowels are much more closed or neutralized.

Brazilian Portuguese Examples:

1. Meus sapatos estão muito sujos. (My shoes are very dirty.)
2. Os seus pensamentos são sujos. (Your thoughts are dirty.)
3. Não use esses panos, eles estão sujos. (Don't use these cloths, they are dirty.)
4. Os vidros da janela ficaram sujos. (The window panes got dirty.)
5. Os gatos estão sujos de terra. (The cats are dirty with dirt.)
