Query: Stopped working

Worked fine for the first few weeks. It is now IMPOSSIBLE to push in thick carpet. I am not sure how I will be able to use the warranty as the nearest service center is 50 miles away. It replaced another Hoover that also became very difficult to push in carpet. I am tired of buying vacuums that work for a few weeks/months and then stop working. I will be shopping for a different brand, one that has a local service shop where I can use the product's warranty.
