Good electrical appliances are immediately needed if heavy rain and flooding hits your application areas. HYDRA and HYDRA-BOY are in such cases often used as helpers, not to leave you alone in the rain. The deliberately electronics-free construction of the mud vacuum cleaners are always ready for use, when its needed. The normally built in electronics in the control panels are not neccessary, due to moisture sensitive. Therefore you can`t find this in the HYDRA-series. Stable components, intensive test series and a perfect design gives you a manoeuvrable and durable machine at hand. Even larger rooms can be so cleaned effective of water and mud, literally to the last drops.
