Intentional Storage
To keep DUO always within reach, it comes with a versatile charging base that can sit on the floor or mount directly to the wall.
Screwless Mount
Both bases install easily with a simple slide-in bracket, giving users the flexibility to store DUO wherever it’s most convenient.
Wireless Charging
Both bases install easily with a simple slide-in bracket, giving users the flexibility to store DUO wherever it’s most convenient.
Swappable Battery
The base battery can be easily removed for recharging, so users never have to move the entire storage base.
Refillable Reservoir
When DUO runs out of cleaner, the reservoir tank is designed to quickly pop out for easy refilling.
Single-Use Brush Pads
Single-use brush pads made from cellulose fiber can be flushed after each use, eliminating the need to store a dirty brush in the bathroom.
Compact Internal Stack
The internal architecture consolidates the diaphragm pump, brushless motor, and 3.2V battery into a compact linear layout, maximizing space while reducing tooling costs through a single parting line.
