I just replaced my original INTEX Vacuum (Ophelia...may she RIP). The old girl had bad hoses (The old style multi-hose set up) and had trouble changing direction. So I purchased a new INTEX hose and vacuum combination from from Amazon for around $85.00.
I could send the parts, or the entire unit, but I think the cost would be cost prohibitive..
PM me and we'll see what I can do...
