If they’re small stops I’d use water bottles. If they’re bigger then maybe a trolley. Harbor freight has a red welding that will fit a standard bucket really well. It has large wheels which makes it easy to move over curbs.
We have a bladder tank on wheels. You just fill the water boy with pure water about 15 gallons and it is pressurized with ball valve. Works great on store fronts. We also have a tool belt strapped to it with trad tools. We also sale this unit which will carry 20 gallons and has a pump control and rechargeable battery.

Thanks for posting. Mind if I ask what were the problems were you attempting to solve by using a trolley system to carry your bucket and gear around while you do your run?
The problem I was trying to solve was downtown Durango Colorado during tourist season. Parking is impossible and route work is a stone bear during peak tourist.
We don’t do route work, however all of our residential window cleaning is performed using 1 gallon jugs with pre-mix solution. We simply poor solution into hip Bucket, dip mop and go. Eliminating dirty water bucket and less water use.
I used to carry a 3/4 full 10L bucket around for years, these days I only carry around a 500ml squirt bottle with solution on my belt on the other side I have my boab (which is not used to carry water, just to catch water), this is mainly for residential and commercial as I do not do store front.
I rinse out my washer when necessary with clean water for a large commercial job I will have a bucket of water that will need to be moved the alternative is to find a cleaners closet every time my washer gets dirty which would not be efficient.
Same for me and I did lots of store fronts. Leaving the bucket in the truck and using a bottle on the belt will save your back. Also take up yoga and learn to do stretching for your back.
