Apparatus for cleaning a submerged surface with easy drainage
Detailed is a device for cleaning an immersed surface including a body and members for driving this body over the immersed surface, a filtration chamber which has a liquid inlet and a liquid outlet, a hydraulic circuit for the flow of liquid between the inlet and the outlet through a filtering device, a handle for operating the body which allows a user to carry it in order to immerse it in the liquid or remove it from the liquid, wherein the liquid outlet is arranged at a longitudinal end of the body, and wherein the operating handle is connected to the body at an opposing end so that, when the body is suspended by the operating handle, it tilts spontaneously under the effect of gravity into an emptying position in which the liquid outlet is located below the liquid inlet.
1. A swimming pool cleaner comprising:
a. a body comprising an inlet, a rear wall having an outlet, and a front portion opposite the rear wall;
b. a pumping device configured to cause water to flow from the inlet to the outlet;
c. a filtering device (i) positioned between the inlet and the outlet so as to filter water flowing therethrough and (ii) having an end proximate the outlet; and
d. a handle connected to the front portion of the body; and
in which the outlet and the filtering device cooperate such that, when the pumping device is inoperative and the body is oriented with the outlet below the inlet, substantially all of the filtered water above the end of the filtering device drains through the outlet.
2. A swimming pool cleaner according to claim 1 in which the handle is rigidly fixed to the front portion of the body in such a manner that it has no degree of freedom relative to the body.
3. A swimming pool cleaner according to claim 1 lacking any non-return valve.
4. A swimming pool cleaner according to claim 1 further comprising a member configured to guide the body along a surface of the pool.
5. A swimming pool cleaner according to claim 4 in which the member comprises an electric drive motor.
