Your guide to pleasure
Lumii™ is a clitoral suction stimulator. Place the mouth over the clitoris and press the button to cycle through 7 suction levels — from feather-soft to powerful. There's no friction and no fumbling; just gentle, focused waves that build as you climb the intensities.
Swipe through our interactive manual to get the most out of your experience. Below, we've broken the whole thing down step by step.
Step by step
Whether this is your first suction toy or you just unboxed your Lumii, these steps will get you from setup to bliss in no time.

Lumii™ is a clitoral suction stimulator. Place the soft mouth over your clitoris — the small, sensitive spot at the top of your vulva — so the opening surrounds it completely. Don't push; just rest it there gently until you feel a light suction forming.
Tip: Get comfortable and private first. A drop of water-based lube around the rim helps create a better seal.

Everything runs through a single button. Press it to turn Lumii on, then press again to cycle through its 7 suction intensities — from feather-soft to powerful. The simple one-button interface means you never have to fumble or look away.
Tip: Start on the lowest setting and let your body warm up before you climb the intensities.

Work your way up through all 7 levels to find your sweet spot. Lumii packs the punch of a full-size toy in a discreet, palm-sized shape, so even the lower settings have plenty to give.
Tip: There's no rush to reach level 7 — most people find their favorite somewhere in the middle.

Lumii™ is fully waterproof (IP7X), so you can take it into the shower or the bathtub. Whisper quiet at 50dB, it lets you enjoy yourself with complete peace of mind.
Tip: Rinse Lumii with warm water after each session and dry it before tucking it into its pouch.
Wait, there's more
Once you've got the hang of it, these little tweaks help you discover what feels best. Every body is different, so experiment and find your favorites.
Ease in on the lowest setting
The first of Lumii's 7 intensities feels light and teasing — perfect for warming up before you turn things up.
Build through all 7 intensities
Press the button to step up one level at a time. Linger on each until you find the suction that feels just right for you.
Fully waterproof, IP7X
Bring Lumii into the shower or the bath. Warm water and gentle suction make for a completely different kind of session.
Find new angles
With the mouth sealed, gently tilt Lumii up and down. Tiny shifts change how the suction lands and can unlock a whole new sensation.
You're in control
Press a little firmer for a tighter seal and stronger suction, or ease off for something lighter and more teasing.
Whisper quiet at 50dB
Lumii stays discreet wherever you are, so you can relax and focus on the moment with complete peace of mind.
