I have had several handheld vacuums and my old ones have always been the best and for years none have been as good as the Hoover ONEPWR. I bought a backup battery and keep one in the charger. If the one I use runs out, I just swap it out. The vacuum cleaner itself is a bit noisy, but the suction power is excellent and it empties easily. I love it so much I bought a second unit with a backup battery for another location. I can recommend this vacuum cleaner.
