Dirt workers = easily enough power to get the muck off, not enough to wreck your bike, without the need for muck off or Fenwicks etc. It’s genius coming home from night rides with a clean bike.
I’ve had mine for a year and a half, ride weekly at least in all weathers, and in that time I reckon there have been maybe 1 or 2 occasions where the bike was so caked in mud I didn’t have sufficient water spare for another bike. Sometimes there’s enough to clean 3. Can get round that by carrying more water in a jerry can.
5 people I ride with have bought them since seeing it in action, and everyone else likes to borrow them which says much!
Dunno about the super powerful version you’re talking about here, but dirt workers do the business for sure, especially if you pick them up at silly prices from Halfords.
