The first impression was good: it came up, it shines in the dark. But then I got so tormented with these traces! No cleaning fun. It also shocks. I do not advise… Got pros: Illuminates the floor, dust is clearly visible. Fits exactly into the original pipe Its cons: 1) On a parquet floor, a vacuum cleaner with this brush for some reason starts to shock. Perhaps the material of the brush is electrified (less on the tile). 2) leaves streaks of dust on the floor. When you change the direction of movement of the brush (back and forth), dust remains on the floor in strips. I tried everything: clean after each use, move the brush sooo slowly. Constantly "wipe" on the rug during cleaning. Useless. Copying, apparently, is not so simple. 3) spends more energy, there is no longer enough for cleaning. 4) the brush is inconveniently disassembled for cleaning.
