Features
Details from the Compo Closet Amazon listing:
- Built for RVs, Vans, Boats & Tiny Spaces - Compact and easy to install, Cuddy fits flush or freestanding in tight areas—ideal for mobile homes, cabins, and boats. Lightweight yet stable for rough roads or choppy water, it's the perfect sanitation solution for life on the move.
- Self-contained composting with Manual Mixer - Add composting material once before use, then mix waste manually after each visit using the built-in handle-operated mixer. No daily material top-ups or disassembly needed—just a quick, simple turn helps maintain airflow and keeps the chamber clean and balanced.
- Odor Free Design with Fan & Filter System - Enjoy a fresh environment, even in confined spaces. Cuddy’s built-in fan and filter system actively removes odors, while the 𝗽𝗮𝘁𝗲𝗻𝘁-𝗽𝗲𝗻𝗱𝗶𝗻𝗴 𝘁𝘄𝗼-𝗽𝗹𝗮𝘁𝗲 𝗱𝗿𝗼𝗽-𝘇𝗼𝗻𝗲 𝗰𝗼𝘃𝗲𝗿 separates liquids from solids to prevent smells. With a sealed liquids bottle and a reliable no-spill valve, you can enjoy a clean and comfortable experience, whether you’re on the road or at sea.
- Easy-Clean Design with Smart Features - Removable solids bin with a bottom handle allows for hygienic, contact-free disposal every 2–3 weeks. The front container features a no-spill valve for quick, clean emptying every few days, and the built-in LED light alerts you when it's time to empty. With a 3.9-gallon capacity, the main bin supports extended off-grid use with fewer trips to dispose of.
- Built for Off-Grid Simplicity & Low Maintenance - Operates on 12V power (cable included) and continues working without electricity when needed. No water or chemicals required. External venting is optional—not necessary for use thanks to the integrated fan and filter system. A simple, low-maintenance solution for independent living, wherever you go.
