You can check ebay, they have lots of electrolux central vac hoses and you can get one with the appropriate handle to attach to your power head and wands and other attachments.

Electrolux makes BEAM vacuums. Any BEAM hoses or powerheads should be compatible. Visit a BEAM dealer in your area.

Do you need a new powerhead too or only the hose? If you need a new powerhead than I would recommend looking at the Imperium Pro Elite Attachment set. It is an excellent quality powerhead and hose. If you only need a new hose than you will need to contact the Aerus because they will be probably be the only company who can sell you a hose that wil be compatible with your powerhead.
