For years, I battled the never-ending chore of vacuuming my home.

Choosing the Right Cordless Stick Vacuum: Factors to Consider
The market is flooded with cordless stick vacuums, all promising powerful suction and convenient features. But choosing the right one requires careful consideration of your needs and living space. If you have pets, allergies, or extensive hard flooring, a vacuum with strong suction and a HEPA filter is crucial. Think about the size of your home; a longer battery life will be essential for larger spaces. Consider your budget – cordless vacuums range from budget-friendly options to high-end models. If you’re primarily dealing with pet hair, a model with specialized pet hair tools might be worth the investment. However, if you have a small apartment and prioritize portability above all else, a less powerful, more compact model might suffice.

Multi-Surface Functionality and Powerful Suction
The vacuum’s auto-adjusting brushroll intelligently adapts to different floor types, optimizing its performance on carpets, hardwood floors, and area rugs. The suction power is impressive, effectively picking up pet hair, dirt, and debris from various surfaces. The inclusion of both a crevice tool and a pet multi-tool further enhances its adaptability and effectiveness in various cleaning scenarios. While some users report a slight decrease in suction after prolonged use, it’s still significantly stronger than many other lightweight models.
Long Battery Life: Cleaning Without Interruptions
With up to 40 minutes of runtime on a single charge in ECO mode, the Shark Clean & Empty BU3521 provides ample power for cleaning most homes. The long battery life is a major advantage, eliminating the frustration of frequent charging interruptions. This ensures you can complete your cleaning tasks uninterrupted and without compromising the efficiency of the vacuum.
