The Mite Exterminator is ideal for primary mite habitats, including mattresses, bedding and home or car upholstery. It uses high-frequency tapping to loosen deeply embedded dust mites and fine dust, suctioning them away in one go. The 2-in-1 Retractable Nozzle is for dust-prone surfaces and hard-to-reach spaces, such as keyboards and plush toys. For the Vacuum Nozzle, it is designed for tight crevices to easily clear larger dry debris such as food crumbs.
