Review: 10/10 - Absolutely amazing vacuum, light weight in comparison to traditional vacuum. Slow to charge, but charge lasts quite awhile. Daily use in small one bedroom apartment, charge lasts about two weeks. Great attachments, easy to disassemble for cleaning purposes, great suction.
Review: One of the Best Wireless Vacuums You Can Buy - If you’re considering a wireless vacuum cleaner, this is hands down one of the best investments you can make. It delivers powerful performance, especially on carpets, picking up dirt impressively well. The battery life is long enough for practical, everyday cleaning, and the whole unit is lightweight and easy to maneuver. What really stands out is the thoughtful design and ergonomic build — everything feels intuitive and well-balanced. Based on my experience so far, it’s a purchase I feel confident about and would recommend to others.
