Vacuum Cleaner

I do wish there was a factory that could make a vacuum cleaner that would work for longer than a about a year. Maybe they do in other parts of the world. But here on the desert they don't. I have had several now in the 6 years I have lived here, and each and everyone, (there have been several different brands) have given up after about a year of usage. The last one is my Bissell Powerforce which I have had for a little over a year. The on/off switch has quite. Once off it doesn't come back on until it decides to. I am sure it is due to all the sand and dust in the vacuum. Which is another thing. How many homes have an air compressor to use to blow out the vacuum cleaner when they have finished using it for the day. It is necessary here. My husband, being a mechanic, has an air compressor which I have leaned to use on my vacuum about once a week to keep the dirt cleaned out of it enough to work. I take all the filers and little parts out, shake out what dirt I can and then use the air compressor to blow out the rest. After which I am covered in a cloud of dust and have to take a shower. But if I don't do this the vacuum doesn't last more than a few months.
Do the vaccum companies do this on purpose so that we have to spend more money to buy more of these necessary evil devices? All my neighbors agree with this. Non working vacuum's are one of the most common item I see at garage sales.
