Optimum Series Ultimate Waterproof — Smart Pump by CalExotics

Optimum Series Ultimate Waterproof User Guide & Play Styles

Stepping up your solo wellness routine with smart-mode control

If you’ve used a basic manual pump and found yourself wanting more precision, the optimum series ultimate waterproof is built for exactly that next level. Engage smart mode and let the device cycle through pressure sequences automatically, or switch to manual mode for hands-on grip and rhythm control. The clear cylinder’s incremental measurements let you track progress session to session — no guesswork. The removable silicone donut adds a tighter, more comfortable feel, and the quick air release button means you’re never locked in longer than intended.

Using the waterproof penis pump in the shower or bath

The IPX7 submersible rating makes this one of the best automatic water penis pumps for wet environments — warm water naturally relaxes the body, which many experienced users find improves both comfort and sensation during a session. The flanged base holds a secure seal even with water present, and the suction stays consistent across all multi-speed settings. After your session, the device disassembles easily for quick cleaning — rinse under running water, remove the silicone donut, and you’re done.
