The average lifespan of a cheap hoover typically ranges from 2 to 5 years. This lifespan can be influenced by several factors, including the quality of the hoover, how frequently it is used, and how well it is maintained. Regular maintenance, such as emptying the dustbin, cleaning or replacing filters, and checking for blockages, can help extend the life of the hoover. While more expensive models may offer longer lifespans and warranties, many budget-friendly hoovers can provide reliable service for several years if properly cared for.
