The Wanda Vac is the ideal cleaning tool for small pools, spas or spot cleaning in larger pools. It is easy to use…there is no set-up, just grab it and start vacuuming! The battery-operated pump creates a strong suction which picks up stones, leaves, sand, dirt and other debris. There are no messy hoses or electrical cords. An aluminum, telescoping handle is included which can be adjusted to different lengths for multiple cleaning applications. The long lasting, stainless steel filter is easy to clean and the clear sleeve shows “at a glance” if the filter is full. Requires 8 AA batteries (not included).
