CUSTOMER NOTICE - This product is a motion sensor trash can. Customers need to install 2 AA batteries and follow the steps to install the trash bag to make sure the trash can works properly. If there is any problem during use, please contact us immediately. Smart Sensors - We have developed sensing technology that reduces unnecessary openings and extends battery life. If you place your hands over the infrared motion sensor, the lid stays open, thus greatly improving the user experience. If the sensor does not detect any movement, the lid closes automatically after 5 seconds. The product is powered by 2 AA batteries (not included in scope of delivery). Dimensions - 11 inches long x 7 inches wide x 12 inches high (approx. 27.9 cm long x 17.7 cm wide x 30.4 cm high), and Waterproof - Advanced IPX5 waterproof technology prevents water or humid environments from damaging the device. No water damage to the surface after rinsing. Stylish and Unique Design - The product's exterior features a novel wavy stripe for visual aesthetics while being non-slip. With its modern oval design, the commercial trash can can be a great choice for bathrooms, kitchens and other rooms while taking up less space. Trash Bag Retainer Ring - The removable trash bag retainer liner supports the trash bag to hold heavier trash. Simply remove the liner and insert a trash bag to hide it inside. CUSTOMIZED TRASH BAGS: Our coded trash bags are designed to fit perfectly in this trash can so they won't slide around and are completely hidden. The extra thick plastic and double-stitched construction prevents rips and tears.
