Bissell offers warranties for its vacuum cleaners. The warranty should cover you for anywhere from two to five years, and that depends on the model. As for the lifespan, Bissell makes reliable products, which means they could easily last for years more than the warranty specifies. Nevertheless, you will need to maintain your vacuum properly to maximize longevity. Do not forget to clean your vacuum from time to time and use it only according to the instruction. You might need to get some replacement parts over time, but if you take good care of your product, it can serve you for years to come.
