I don't want to attempt this without knowing what I'm doing and there seems to be a video online for every other issue but this one. Any specific help would be much appreciated!! Thank you!

How do I replace the lower internal hose? I can't find any info on this particular hose. I'm assuming it must be an easy fix? Help please!

I need to replace the motor of my DC01. I can remove the sole plate brush bar etc. I looks as I need to remove the 8 Torx 15? Screws to get at the motor but there is a plastic part that impedes access. Can anyone provide dismantling instructions? Thanks Chris

The hose on a Moen kitchen faucet has a hole and needs replacing. I got a new hose but was going to reuse the sprayer head itself. How do I get the head off the old hose and on to the new one. Do I need to get a new spray head too?
