More particularly, the invention aims to provide such a device whose cost can be substantially lowered, for equivalent performance, or even greater than those of known devices.
  • the invention also aims at providing such an apparatus, the filtering device can be easily dismounted to allow cleaning of the latter while having high hydraulic performance (flow, suction, ...) and filtering.
  • an apparatus according to the invention can be provided with a much lower power driving device, and thus with reduced consumption and costs. This also results in a lower overall volume and a lower weight of the apparatus which, in addition to the economy achieved, is an important advantage for the user, particularly in terms of handling, transport and storage of the apparatus. .
