- False friend: 'чашка' (cup) is correct, but the concept is 'присоска' (prysoska). Direct translation 'всасывающая чашка' is overly literal and not used.
Common Mistakes
- Using 'suction cap' (less common). Confusing 'suction' with 'absorption'. Incorrect preposition: 'on the window' vs. 'to the window' for initial attachment.
