Cleverly shaped like a water droplet, this battery-operated water-leak detector offers features typically found in pricier models, such as temperature and humidity sensing. There are probes on the bottom and a 4-foot extension cable with a water sensor at the end, useful for sliding under appliances.
The device is Wi-Fi-enabled, though there’s no smart-home integration capability (somewhat commensurate with the price point). Another downside is that the siren isn’t as loud as some other models.
Still, the Flo Smart does pair with the brand’s auto-shut-off water leak detector, which we cover below. For expanding coverage, you can connect up to three add-on sensors. Moen sells the device singly or in packs for extra value, and with upgrades like a 6-foot water-sensing cable.
The bottom line: If you live in a relatively small space and don’t want to spend a ton, this little device gives you peace of mind without putting too deep a dent in your budget.
