What is the difference between C1 and R1?
Both share the same foam system, dimensions and mounting. The difference is power and activation: C1 has a built-in 18650 3000mAh battery lasting about 45 days per charge; R1 runs on a 5V/2A adapter and adds an RF remote.
Is the R1 remote infrared or RF?
It is RF (radio frequency). You do not need to aim it — it works through walls, so you can press it at the door and the foam is ready when you arrive.
Does the foam liquid have a scent? Is it harsh?
The formula is mild and neutral with a light scent. Fragrance and ingredients can be customized for OEM orders.
Can it be used with a smart toilet?
Yes. The unit mounts independently and does not modify the toilet. It only taps into the inlet valve and does not interfere with a smart toilet seat.
Installation
Do I need to drill?
No. It mounts with a heavy-duty adhesive pad — no damage to the wall, renter-friendly, and removable when you move.
Must it be connected to a water line?
The tank auto-refills when connected to the toilet inlet valve. Without that connection you can also fill it manually.
It is 75mm thick — will it get in the way?
At only 75mm deep it sits flush against the wall and takes no usable space.
Do I need a professional to install it?
No. Three steps take about 3 minutes: mount, connect water, add foam liquid. A manual and install video are included.
Consumables & Power
How long does one bottle of foam liquid last?
A 150ml bottle gives about 180 cycles — roughly 45 to 60 days at 3 to 4 uses a day.
How long does C1 take to charge?
It charges on DC 5V and typically reaches full in a few hours, then runs about 45 days.
Can R1 work during a power cut?
No. R1 has no internal battery and needs mains power. If outages are frequent, choose C1.
Where do I buy refills?
From our website and official stores. Bulk orders and custom formulas are also available.
After-Sales
How long is the warranty?
12 months on the unit, with free repair or replacement for non-human damage.

Yes — 7-day no-questions returns if the item is resalable. See Shipping & Returns for details.
