Do not attack? Don't you mean talk?
As you will see from the previous replies sent by other members on here, others would beg to differ to your opinion regarding carpets in hospitals and - and rather than continually knock me down - prepared to watch, read and listen. If you can't do that, then you're on the wrong forum.
Furthermore, hospitals use all kinds of textures including that rubberised flooring that can be hard to clean. The polishers are useless - the machines that my local one uses is amazing - a Karcher upright that washes the floor, cleans the floors, scrubs the floor clean and not that noisy.

As for your SEBO brush roll, well they don't last forever which is why the models do carry a brush warning light. If you actually owned a SEBO you would know that, or any less the Windsor Sensor series that offers the same LED panel. UNLIKE Miele, SEBO further offer TWO different kind of brush rolls, the green one for delicate flooring and the normal blue one. UNLIKE your Miele, you can't change the brush roll any less either for cleaning it off if pet hairs get wound up it - with the SEBO/Windsor, it's just a simple press of the button and pull out.
Also schools have deep carpets but it depends on where they are located - and SEBO uprights are used to clean them too.
I've worked with cleaning companies and I certainly know the machines we've used. Your experience may differ from mine, and I'm glad of it - but don't try and battle your wits with me and pap off any old BS.
