Will this fit the XERO carbon fiber trad pole 2.0, and is it hard rubber or soft? Which rubber do you recommend?

Great question! This squeegee is compatible with the wooden cone that comes standard with the XERO Trad Pole, but you can also select an Unger Pole tip for a locking option. This squeegee comes with one strip of soft Unger ErgoTec Squeegee Rubber that can be ordered separately in hard or soft. The colder your temperatures you will be working in, the softer rubber choice you will want to select, but it does really come down to personal preference!

Does this fit with the Ettore REA-C-H Extension Pole

This will fit via pressure fit.

Can I use the red facelift rubbers with this squeegee? Or so I have to use the ergo tech rubbers?

Facelift RazrBlade Red Squeegee Rubber is compatible with this channel.

Does it swivel?

Yes, the handle has a 180 degree swivel head.

What type of pole can be used with this? typically, how long does the rubber last? This is my first ninja. What is the best size to purchase?

Any Unger pole could work with this handle. Depending on use a professional squeegee rubber will give good results for several days. 14" & 18" are the most popular sizes.

Does the product allow me to (screw in) my pole into the handle?

It does not screw in but simply slides on

Just making sure the black diamond ruby red fits the unger ninja?

Yes it does.
