No. 4 is pressed by the weight of the machine body, and is in a state of having the same thickness as the diameter of the short roller 18. Further, as shown in FIG. 7, the porous rubber 15 does not absorb water, but is compressed by the weight of the machine body, enters the concave portion of the floor surface F, and works to push out the water in this portion in cooperation with the squeegee rubber 16. Of course, on a flat floor, scrape off the water with the bottom surface of the squeegee rubber 16.
After this is sucked into the sponge 14, water is absorbed.

う。The contaminated water is vacuumed by the water absorbing section 3 of the present invention. Water absorption part 3
The sponge 14 and the porous rubber 15 are pressed and compressed by the weight of the machine body.
Since the compression amount is limited by 8 so that it is not pressed further, the sponge 14 can appropriately absorb and suck up the contaminated water that is stopped by the squeegee rubber 16 and pushed back. At this time, if there is unevenness on the floor surface, the porous rubber 15 will enter this portion and the squeegee rubber 1
Instead of 6, it works to stop the contaminated water in the recess and push it back.
かくして吸水部３で相当程度に汚染水は吸いとられる
が、さらに次の拭取部４において拭取紙２７によって床
面は完全に拭きとられて乾燥する。このとき、フリーロ

ことができる。Thus, although the contaminated water is absorbed to a considerable extent by the water absorbing part 3, the floor surface is completely wiped off by the wiping paper 27 in the next wiping part 4 and dried. At this time, the free roll easily fits into the unevenness of the floor surface and can completely wipe the floor surface.
（効果） 洗浄部と、汚染水の吸水部と、床の拭取部とを１台の機
枠にコンパクトに装着し、動力で自由に移動できるよう
にしたので、極めて能率的かつ安全な除染作業を可能と
するものである。(Effect) The cleaning unit, the water absorption unit for contaminated water, and the floor wiping unit were compactly mounted on a single machine frame, and allowed to move freely by power, so extremely efficient and safe removal is possible. It enables dyeing work.

るので、除染効果は完ぺきである。In particular, the water-absorbing part of the present invention is a sponge rubber that dams the contaminated water pushed back by a squeegee rubber and a porous rubber that enters the recess of the floor and replaces the squeegee rubber. The decontamination effect is perfect because it can be absorbed into the soil.
