Used for only 3 days. Selling because I bought a new one. Available for immediate purchase. Thank you. 【Cordless Pump & Safety Structure】The water tank is separated from the power supply, and the cords are not wired inside the tank, making it a removable structure. Since it does not conduct electricity, there is no need to worry about electrical leakage. It is safe to use even when plugged in. 【Cleaner Water Supply】Using a 3-layer filter prevents the accumulation of dirt and suppresses the growth of bacteria, providing cleaner water and helping to maintain the health of your pet. 【Built-in Long-Lasting Battery】Once fully charged, it can be used for up to 60 days! There are no restrictions on the installation location, and it will function anywhere. 【Selectable Water Supply Modes】You can choose between continuous water supply and sensing water supply, and switch between them according to your cat or dog's drinking habits. ● To use the continuous water supply mode, you need to connect the USB charging cord to the power supply. ● Sensing water supply mode: To attract the attention of curious pets, the water dispenser dispenses water once when it detects a person or pet approaching. *You can set the water dispensing time and sleep time in the ROLA app. 【Design that Reduces the Burden of Drinking】The height to the water spout is about 16cm, so your cat or dog can drink in a comfortable posture without bending their neck too much. The wide and shallow shape of the tray maintains an easy-to-drink slope without getting your cat's whiskers wet. 【Monitor Hydration with the App】By recording and accumulating data on your cat or dog's daily drinking time (duration) and drinking patterns in the ROLA app, it helps to maintain your pet's health. *You need to download the "ROLA" app to use the monitoring function. 【Easy to Clean】It has a simple structure, and the water tank, tray, and each part can be easily cleaned and maintained. 【Can be used in conjunction with the pet camera "ROLA Mini"】When a pet approaches the water dispenser, the water dispenser activates the recording function of the ROLA Mini and starts video recording. *The water dispenser needs to be placed within the field of view of the ROLA Mini camera beforehand.
