10 Best Pet Urine Detectors 2025 in the United States

The Vansky UV Flashlight Black Light is designed primarily as a pet urine detector, making it a useful tool for pet owners who need to identify hidden stains and ensure their living spaces are clean. It uses a 395nm UV light wavelength, which is effective in illuminating invisible stains caused by pet urine, food, and other substances on various surfaces like carpets and fabrics. With 51 LEDs, this flashlight has a notably long lifespan of up to 15 years, ensuring good value for your investment.

One of the strengths of this product is its versatility. Besides detecting pet stains, it can also be used for tasks like authenticating currency and inspecting cosmetics for unwanted agents, making it useful beyond just pet care. Its compact, portable design allows users to easily carry it around, which is a plus for those needing to check for stains in multiple locations, even outdoors.

However, there are a few drawbacks to consider. First, the flashlight requires 3 AA batteries which are not included, so you'll need to budget for batteries as well. While it has a durable aluminum build, some users may find it less robust compared to heavy-duty models on the market. Additionally, while the UV light is effective, it may not be suitable for larger areas without a more powerful alternative.

The LUMENSHOOTER S3 365nm UV Flashlight is designed for pet urine detection and other uses like resin curing and scorpion hunting. It features three powerful SMD 365nm LEDs, which produce a purer light color and clearer images of pet urine stains than the more common 395nm LEDs. This makes it highly effective at revealing invisible stains on floors and even on grass. The flashlight's material is aluminum, which adds to its durability and build quality. Users can expect a robust device that is also waterproof, enhancing its reliability for various tasks.

The flashlight operates on a rechargeable Lithium-Ion battery, which is included, along with a charger, and offers a runtime of approximately 4 hours. This is beneficial for extended use without frequent recharging. Weighing around 11.3 ounces and with dimensions of 5.7 x 1 x 1.75 inches, it is portable and easy to handle. One potential downside is that it might feel slightly bulky for some users. Additionally, the included manual helps ease the learning curve, making the device user-friendly.

With powerful LEDs, there might be a need to handle it with care to avoid eye strain or damage. The flashlight comes with a 1-year manufacturer warranty, providing some peace of mind regarding its durability and performance. In essence, the LUMENSHOOTER S3 is a powerful, durable, and effective UV flashlight, particularly suitable for pet owners needing to detect urine stains and those with other UV light needs.

The LUMENSHOOTER S5 UV Flashlight is a strong candidate for detecting pet urine thanks to its 365nm UV wavelength, which effectively makes urine stains fluoresce. It features 5 LEDs that provide a bright and wide beam, reportedly three times brighter than previous models, helping you spot hidden dried stains even in large or dark areas. Powered by two rechargeable lithium-ion batteries, it delivers around 2 hours of continuous use per charge, which is sufficient for typical home cleaning sessions. Its aluminum body enhances durability and provides a sturdy feel while being waterproof, allowing for indoor and outdoor use without worry. The included USB charger and batteries make it ready to use right out of the box, simplifying setup.

Weighing 1.48 pounds, it might feel somewhat heavy for prolonged handheld use. Additionally, the 2-hour battery life could require recharging during extended tasks. While it excels in brightness and range, the weight and battery runtime may be less comfortable for quick spot checks or frequent carrying.

Beyond pet urine detection, this flashlight is versatile and useful for curing UV resin, rock hunting, and even scorpion detection, demonstrating its broad utility. It is a bright, reliable UV light well-suited for finding pet stains, particularly if you value a durable build and rechargeable batteries.
