Do Shark vacuums last a long time?

This is where reviewers disagree most. High-trust testing outlets rate Shark uprights highly for cleaning performance and value, but r/VacuumCleaners threads repeatedly raise durability and suction-fade concerns after several months to a year, and note sub-$300 models are generally not very repairable. Buyers prioritizing longevity often cross-shop the Miele class.
