What to know before buying

The listing describes sensor mode as activating when a pet approaches within a 120-degree range, timed mode as running for 20 seconds every 20 minutes, and continuous flow as plug-in operation. On battery power, continuous flow is said to switch automatically to sensor mode after 30 minutes. The 4000mAh battery and the battery-life feedback do not establish runtime between charges. Filter cartridges require regular replacement, and the listing names a search item number for replacements.
