Lightweight and inexpensive yet solidly constructed, the Eureka 4700D LightSpeed offers an excellent value in a full-size upright vacuum. The cheerful yellow unit is easy to push and maneuver, offers powerful, 12-amp suction, and even uses micro-filtration to capture dust mites, pollen, and pet dander for cleaner, healthier indoor air, whether you have allergies or not. Like other bag less models, the LightSpeed eliminates the expense and hassle of disposable vacuum cleaner bags, using instead an easily accessible, easily-emptied dirt cup that's transparent so you can see when it's full. The filter needs to be cleaned often, especially if you have pets, to get the best results. This is also common with other bag less vacuum models.
