Both the Dirt Devil Gator BD10165 and BD10125 received an A minus rating from Good Housekeeping, which bases its ratings on a number of factors, including performance, safety and ease of use. Choosing the best handheld vacuum really depends on its intended use, as different vacuum models are designed for different tasks, such as for carpet, cars or stairs.
When choosing a handheld vacuum, the first item to consider is corded versus cordless. Corded handheld vacuums are typically more powerful than the cordless varieties, but they are not as portable, as they require a power source. Cordless models are typically more expensive, but they utilize rechargeable batteries to operate, making them ideal for certain locations, such as the car.
Another important consideration is the vacuum's performance capabilities, including the motor size and whether it has a rotating brush. Typically, the higher the voltage rating on the motor, the better the vacuum's sucking capabilities. Not all handheld vacuums feature a rotating brush, but if the intended use is for carpet, a brush and a high-voltage motor will allow for better performance capabilities.
Other features of handheld vacuums include additional attachments such as nozzles and crevice tools, as well as wet-dry capabilities, among others. When choosing a handheld vacuum, consider its intended use to determine the required size and capabilities to complete the tasks.
