Funny. There is a little more to it than that for building a functional and lasting handle for a surface cleaner. Getting all the angles aligned correctly, by my calculations you would need to have 4 angles, all in different directions for a once piece handle. Then not having crimped bends in the tubing is essential for this because improperly bent tubing will lead to metal fatigue and eventual failure. Of course you could do it, but I would suggest welding gussets onto the bends if you use a pipe bender at lowes or depot.
I may be over thinking this. You could also get on craiglist and find a used lawnmower, strip the handles and use that, but that would also need fabrication and likely some welding.
