Stop pressure hose getting tangled

[Pedal_Loud]

When I'm pressure washing both cars on the drive, I'm usually pretty careful getting the hose in position etc but sometimes it just catches between driveway and tyre of one of the cars. It's a Karcher washer and every time I'm cleaning my cars it drives me mad. Is there any kind of product that people are aware of that could help stop this? I'm thinking some click/clip on plastic balls so that the hose reel moves freely over the ground. I'm sure I saw something like this before but can't seem to be able to find it. Any ideas?
