How to replace Dyson V8 Absolute Battery and Filters

Ansanor 21.6V 3500mAh Li-ion Replacement Battery Compatible with Dyson V8 Absolute Cord-Free Vacuum Handheld Vacuum Cleaner . My believe that any mom of young kids must have Dyson cord-free vacuum. I have three little boys, and they are messy like their life depended on it. I bought Dyson V8two years ago, and I'm using it a dozen times every single day. No surprise that the original battery could not hold the pressure anymore. To my surprise, the Ansanor replacement battery is much more powerful than the original one. I'm using it about a week (dozen times every single day) and the battery holds the power like a boss and the suction is so much better, that I rarely use the Max mode now. The new battery perfectly fits the charging dock. My husband filmed a short (and funny) video showing how to replace the battery and both filters. By the way, so far this was the best deal on Amazon - battery and four filters for the price I paid. . .
