Key features

• •【Auto IR SENSOR Mode + Normal Mode(constant flow)】AUTO mode: Fancy blue light turns on and water comes outs as your pet enters into the sensing area(sensing angle: 120°| sensing distance: 3.93ft), and shuts down when pet leaves. The added sensor helps save power and extend the longevity of the water fountain, especially makes the backup battery last when the cat fountain auto switches to battery supply in case of a power cut.
• •【DC Plug-in Power + Battery Backup 】Run on plug-in power for indoor use, or batteries for outside use, or both for the added battery backup feature: Load batteries and then plug in, it will default to DC power priority, but once a power cut occurs, it will auto switch to battery power supply and auto mode to continuously work with the least battery consumption to let you be absent as long as it possible(up to 30 days), with the peace of mind that pets' water supply won't be interrupted.
