I've been using Shurhold's brushes for years. Good quality. Reasonably priced. I was not aware of Swobbit before your post.
Web site shows some advantages over Shurhold with the poles. I was not familiar with these products till just now. I wonder the prices differences between the two vendors?
I have some Swobitt attachments, they are high quality. The lambs wool pad is great for clear enclosures with no fine scratches. Squeegee also attaches to an adjustable handle, works good too.
I much prefer the shurhold stuff. Although I really like this washdown brush from TD Mop, called a big bird. It has brushes on the sides of the head too and makes quick work of corners and such
