Frequently Asked Questions
Does the NEOREST AS require power?
Yes — electronic features (auto-open lid, EWATER+, heated seat, etc.) require a standard AC outlet; consult the installation guide for exact requirements.
What are the flush volumes?
Dual flush: 1.0 gallons per flush (solids) and 0.8 gallons per flush (liquids).
Can I still flush if the power is out?
Yes. A manual flush via the chrome trip lever is available so the toilet remains functional when electronics are offline.
Is the bowl easy to clean?
Yes — CEFIONTECT® glaze, PREMIST® and EWATER+® reduce residue and make cleaning easier.
Is the toilet comfortable for taller or mobility-limited users?
Yes — the Universal-Height seat (~17.25") makes sitting and standing easier and meets ADA-friendly height for residential installations.
What maintenance is required?
Regular wiping with non-abrasive cleaners is recommended. The anti-stick glaze and automatic PREMIST / EWATER+ features reduce the need for aggressive cleaning; follow the manufacturer’s care instructions in the manual.
Can I install this myself?
This is a floor-mounted, one-piece toilet that requires a standard water hookup and a nearby outlet for power. Many customers use a professional installer for plumbing and electrical hookup; consult the installation manual or a licensed professional if unsure.
