The Electrolux Oxygen 3 is a piece of ****. I was dupped into buying because Consumer Reports said it is a high quality product. Wonder how much they paid for that endorsement! I the brush roller design is flawed and clogs all the time and then will break, the electrical cord doesn't rewind very easily and the swivel head just broke on me after a year and a half of use. RETURN IT! Just in case you didn't know. Electrolux is the same brand as Hoover (same parent company) and I don't like Hoover either.

You will need to replace the hose, which has the on off switch built into it, and this will solve your problem

Check all the wiring connections to make sure they're tight.
1/2. Wiring to power nozzle motor or reset switch is loose.
1. Cord from power nozzle to upper wand. If the plastic portion of the wand is cracked near the cord connection, or the connections are blackened, they need replaced.
2. Wiring connection from hose handle to upper wand. Check for cracks and discoloration as in 1 above. Replace if necessary.
3. Hose connection to vacuum. Not likely, but possible.
4. There could very well be a break in the hose wiring.
You may need to take your vacuum, with hose and power nozzle, to an authorized Aerus Electrux service shop. They can try a new hoze to see if that's the problem. If there is a break in the wiring, the hose is probably worn in other areas as well, and should be replaced.
