Query: Disposable Vacuums

Eureka used to sell a quality product, but the last two (including this model) are poor products. The first few times you use the vacuum, you will be impressed at how much suction they have. After that, it is all downhill. You will find yourself constantly cleaning filters, buying filters and performing maintenance to keep the level of suction that you had when you first purchased. Spend the money upfront and get a better vacuum from a better manufacturer.
