Find a wash
Open the app and the nearest washes are right there — search, distance, and a tap to start.
Sign in
Apple, Google, or email — saved to the device, never re-prompted.
Wash on demand
Pick a bay, start the wash, watch the timer — no tokens, no coins.
Manage on the go
Lock a bay, run a service, settle a transaction — from your phone.
Pick a wash, tap to start, and watch the timer — that’s the customer experience, on the phone in your pocket. Available now on iOS and Android.
The MonsoonOS Platform app works across every wash on the platform — sign in once, then start washes anywhere you’re a customer. Operators on the fully branded app option ship their own dedicated app instead.
Scan with your phone’s camera
One web app for owners, managers, and staff. Role-scoped per location — so the right people can do exactly what they need to, and nothing more.
Multi-location command center — every machine, every transaction, in one place.
Coin-op and card-swipe systems made wash businesses run. They also kept owners on-site, kept customers fishing for coins, and kept data trapped in a paper roll. We took every one of those frictions apart.
Live customer · Cave Creek, AZ
A self-serve dog wash in Arizona’s high desert, running on the MonsoonOS platform. Their customers see their logo, their colors, and their bays — “Barrel,” “Saguaro,” “Cholla” — never ours.
Cactus Wash Systems LLC is an Arizona-based software company building MonsoonOS, a white-label SaaS platform for self-service car wash and dog wash operators. We take the equipment and payments side of running a self-service wash off the operator’s plate so they can focus on the parts that grow the business.
MonsoonOS is what you’d build if you started from the customer’s phone instead of the kiosk. Saved card on file. Tap to start a wash. Subscription Plans that renew themselves and Wash on Demand that just works. Live equipment status from anywhere. And — the thing that actually moves the needle — operators can either use the MonsoonOS Platform app or upgrade to a fully branded mobile app, so the customer experience reads as the operator’s, not ours.
Headquartered in Cave Creek, AZ. Reach the team at sales@cactuswashsystems.com or read more on the product page.
