Review: My poor vacuum had died in the middle of vacuuming and would not charge. I tried everything from deep cleaning it, cleaning the charging contacts, cleaning the docking station, emptying everything, and manually placing it slowly on the charger. Nothing would make a difference, it would just flash quickly and never take a charge. After installing this battery (which was extremely easy) i was able to turn on my vacuum, it automatically reconnected to wifi, and worked as it did on day one. It holds a charge perfectly and charges without issue
Review: The battery received in good condition and works well.
