We have wool from the sofa cleans perfectly. With a manual brush, this will definitely never be achieved, and I would not try other vacuum cleaners, since this one copes with its task by 100%. The adapter that was included lasted exactly 2 minutes, since there were spare ones at home. I'm not sure about the need for a UV lamp, but let it be ๐ I advise everyone who knows dogs and cats. It's quite noisy, but I wouldn't take that as a negative.
