Hot tub care, simplified

Works on its own — the app is optional.
The AutoChlorinator™ runs without Wi-Fi or an app. Want to peek? An optional app shows your water from your phone, anytime.
Mess-free refills, only a few times a year.
Topping up chemicals and reagents is quick, clean, and safe — and you only do it every few months.
Bring your own chemicals.
No proprietary cartridges. The AutoChlorinator™ is vendor-neutral, so any reagents or chlorine you like will work.

See your water. Only if you want to.

Your hot tub runs on its own — no phone required. But when you're curious, an optional app shows you exactly what's happening.

Runs without you

It keeps your water right whether you're watching or not — no Wi-Fi, no app, nothing to check. The everyday default is simply: forget about it.

Optional

A glance, when you want it

Open the optional app to see your water chemistry from your phone — at home or away. Know it's clean and balanced before you even lift the cover.
