The worst sucker I've ever had

I do not know what got into me, to buy this product. Normally I never buy any products, which are touted on TV, but I thought, ok, so a vacuum that must suck and I did not want to follow suit.
What I have now are crumbs on the floor and a vacuum cleaner, in which you do not even feel that it sucks when you hold hands under the nozzle. Even when I take the floor nozzle I feel just a little tickle, reminiscent of sucking.
A Disaster. I just dumped the cat litter, very fine, almost like sand that sucker sucking on nothing, absolutely nothing. I got the nozzle on each individual grain held and even remained lying.
I can only advise against this unit, who wants to soak up his crumbs should purchase another product.
