Juggernaut's a carry, yet he's also a hero who has as much earlygame impact as a support. His skillset is also great for pushing.

You can use items while spinning. Namely, Phase Boots, TP Scroll/Travel Boots, and Diffusal Blade.

While Omnislash instakills any lane or neutral creeps it's still better to only use it with heroes around.

If you don't give the Healing Ward a command, it will automatically follow you.

Juggernaut gets outcarried by most other carries. Try to end the game before 30 minutes.
