Surface cleaning device
Surface cleaning device, comprising a cloth (C) placed on a porous material (PM), a reservoir (R) for collecting liquid absorbed by the cloth (C), and an arrangement (P) for applying under-pressure in the reservoir (R) so as to transfer liquid from the cloth (C) into the reservoir (R). A pore size of the porous material (PM) is between 1 μm and 50 μm.
1. Surface cleaning device, comprising:
a cloth (C) placed on a porous material (PM), a pore size of the porous material (PM) being between 1 μm and 50 μm;
a reservoir (R) for collecting liquid absorbed by the cloth (C); and
an arrangement (P) for applying under-pressure in the reservoir (R) so as to transfer liquid from the cloth (C) into the reservoir (R).
2. Surface cleaning device as claimed in claim 1 , wherein the cloth (C) is a thin microfiber or non-woven cloth.
3. Surface cleaning device as claimed in claim 1 , wherein the porous material (PM) is a porous plastic or a porous polymer with water permeable properties.
4. Surface cleaning device as claimed in claim 1 , wherein the porous material (PM) is hydrophilic.
5. Surface cleaning device as claimed in claim 1 , wherein the porous material (PM) is a part of the reservoir (R).
6. Surface cleaning device as claimed in claim 1 , wherein the porous material (PM) does not allow the liquid collected in the reservoir (R) to come out again through the pores.
7. Surface cleaning device as claimed in claim 1 , wherein the porous material (PM) and the cloth (C) are one multilayer component.
8. Surface cleaning device as claimed in claim 1 , wherein the arrangement (P) for applying under-pressure comprises a syringe.
9. Surface cleaning device as claimed in claim 1 , wherein the arrangement (P) for applying under-pressure comprises a pump.
