Using an 8' step ladder, a 12' long extendable painter's pole, bucket with hook, and that spoon gutter cleaner, you can clean a lot of a side of the house's gutters without moving the ladder.
If you have 2 guys doing this then you can knock out the worst house in no time and not make a huge mess. Dump the bucket full of debris into their trash can, if it is all wet then put small trash bags into the bucket first then they empty out quick and clean.
