Having trouble choosing which Giraffe wall-mounted pressure washer

I've done a lot of reading, watching, and thinking about the Giraffe wall-mounted pressure washer. I'm aware it's not perfect but hopefully will be good enough for home DIY use.

I'm not sure if links are permitted here, but I see on Amazon there's a Pro that's $450 US, and a Plus that is currently $340 US but is sometimes $400.

I'm having trouble differentiating between the two. Both seem to have the same replaceable hose. The Plus is available in two colors, but that isn't important.

I'll gladly pay the $110 extra if the Pro has something better, but I can't figure out any major difference.

This will be mostly for automotive use, but occasional cleaning of outdoor furninture and things like that.
