worker's aid

An uncle who owns an industrial firm is on the lookout for effective yet affordable pressure washers that he can use in his business. We have directed him to a site where he can find helpful and useful facts to aid him in deciding which will be the best for him. It's a bit pricey I would guess but it will save his workers time and effort so work is done fast and effectively. He gave himself a deadline until the end of the month so I might as well help him out in scouting for one now.
