like the sorbo alot but have trouble changing the blades . Any suggestions

Hi Bill! We suggest using some soap to lubricate the blades for easier changing. If you still have a difficult time, give us a call and one of our product specialists can jump on FaceTime to help troubleshoot! 

Can the swivel be locked off on these squeegees

While you can't technically lock the swivel completely, you can carefully tighten the screw to keep it more stable. 

Will this attach to an unger tip?

Sure! This squeegee is compatible with Unger pole tips via pressure fit.

Could you screw this on a mr.long extension pole?

Sörbo is compatible with Mr.LongArm pole tips via a pressure fit.

I'm looking to buy replacement rubber for my Sorbo quicksilver. My question is: What rubber comes in the quicksilver channel when it comes from wcr, or the factory?

The quicksilver channel originally comes with the Sorbo Natural Soft Squeegee Rubber

Where are these manufactured?

They are produced out of California.
