Numatics are everywhere in Britain lol; I bet all Schools, hospitals, offices, shops, building sites, hotels, airports, shopping centres and Churches/Mosques etc use either a Numatic and/or a Sebo as the most reliable, heavy duty machines are required. Henrys are tanks, I have only ever seen one broken Henry which was an oldie and looked like a builders vacuum (at a carboot sale for £10) Even for a Henry I thought it wasn't worth it.
People really do love Numatic. You know how Henrys used to be sold for £89 like 10 years ago and prices *slightly* increased over the years to todays £120? Well, once I seen a used Henry Xtra on an eBay auction sell for £97!
