OMG, Schulmeisterli [Anonymous] should not be flogged with a wet leek for his bünzli-like bossiness, but congratulated with kettledrums, trumpets and marching flags for his observant eye.

Perhaps work a little on understanding punctuation (comma after 'pipe cleaning'). Or interpret 'raw cleaning' not only as cleaning vegetables, but perhaps also as 'pipe cleaning'. So that we know who is using which 'device' during the flirtation. But that's just a side note...

I think that is a typing error. Other portals say "Rothenberger compressed air pipe cleaner". It works perfectly and you only need air pressure.

Thank you for this exhilarating yet useless question, for which you wasted a few kilobytes in my email inbox and I'm sure a few others.
