I am changing my review, because. had to cover the largest area. Structured pine floor. The nylon brush performed well, picking soft fabrics with confidence. I tried it with a metal brush, it turned out that the wood burned a little and became grayish-dark (veined, very beautiful, but for a long time). He does not take corners, he leaves about 7 cm unprocessed (he processed with a drill with a brush for metal). In general, very satisfied.
