using buckets

[Christopher]

I had a couple of questions for those that do a lot of windows. I like the idea of the Quadropod with the bucket at a good height but I really like the rectangle buckets better so I do not have to dip the washer in at both ends but would like something that would do the same thing without being bulky and blocking traffic on sidewalks or in front of stores.
1. Does anyone have anything that works for them or made something?
2. Is there anything available for the rectangle buckets that has wheels, at waist height or a little bit lower and a handle to move easily?
Thanks.

Sorbo's Leif Cart is the closest thing I know of.
It's not waist high, though.
