The Big Ball Turbinehead is a bagless canister vacuum featuring a "self-righting" chassis. If the vacuum is knocked over during use, the center of gravity is designed to automatically return it to an upright position. The chassis is constructed from Acrylonitrile Butadiene Styrene (ABS), and the clear bin is made of polycarbonate. This model uses a turbine-driven floor head that relies on the vacuum's airflow to rotate the brushroll.
Specifications include a whole-machine HEPA filtration system and a large-capacity bin with a hygienic emptying mechanism. To maintain the system, the lifetime filters should be washed monthly and must be allowed to dry for at least 24 hours to prevent mold. The bin release actuator is a moving plastic part; keeping the gasket track clear of debris will prevent the mechanism from sticking or snapping.
- The self-righting design is particularly helpful in homes with many obstacles where a traditional canister might tip over frequently.
- A 360-degree articulating handle allows for a greater range of movement without straining the wrist.
- The sealed system is effective for trapping dust and allergens, making it a good choice for sensitive households.
Because the head is turbine-driven, it may be less effective on thick carpets compared to models with an independent motor in the nozzle. For a canister with a motorized head for deep carpet cleaning, the Kenmore Elite 81714 is a more powerful carpet-focused option.
Maneuverability is a major factor in the upright and canister vacuums category, with various designs tackling the problem differently.
