any good?, never used swivel

[Soupy]

Takes a few goes to get used to but yes, pretty good.

Great on 2 storey work; a nightmare 3 storeys and above (get the swivel pointing down and there is little chance of getting it back horizontal with the pole extended at proper height.

couldn't get used to it. Had goose neck also. Went to mates whos done it for years. He stripped it to basic and its much better and lighter

For domestic I couldn't work without a swivel brush.
Brush is always flat on the glass no matter where I stand.
Is there another way?

I can work very easily with a swivel gooseneck or a carbon fixed gooseneck. I couldn't get on with working with a 25 inch gooseneck on very deep recessed windows and over awkward, very high bay windows (40ft+) on commercial work, happy working with a 10 inch gooseneck but 25 inch is a bloody nightmare to work with even on solar panel cleaning. For very challenging windows I use a 10 inch carbon gooseneck with a swivel glued on the end for extra flexibility to access them very awkward ones.

i couldnt get on with it.hated it even.much prefer a fixed brush.

[DeLuce]

Yeah, they are very useful. Great on domestic round. Excellent for using on triangular shaped windows and long reach awkward access windows. Also saves lots of bending down when cleaning close to ground glass (patio doors etc).
As people said above, just takes a little getting used too. Make sure the screw on the swivel is tight enough to your style, once you've worked that out you should be motoring

It's too advanced for normal window cleaners. Only top earning five percent can use them I've found.
