Review: Works for my Govee Robovac - Tight but Fits! - Govee doesn’t even sell their models on here anymore *sigh* Bought robo vacuum and didn’t even open until after the return window (of course) moving into the new address. It was used. Wrapped up nicely, but used. I could tell by the dirt in the filter/container. The moment I went to test it after a 24 hour charge, it would die immediately. I looked and the vacuum switch was already set to “ON” So my theory is someone used it, emptied, returned, and the battery was left on and uncharged all the way from when I bought it till I pulled it out to use it. This battery worked!!! I now have a functioning vacuum!! I was worried this wouldn’t work because it was a tight fit. This battery pack is just slightly larger than the one that was in the vacuum. I had to shimmy it into place but I’m so glad it works… good buy!! Battery holds charge well, and my “new” used robot vacuum purchased as new wasn’t a total waste of money. Thank goodness!
Review: Perfect replacement for RV750 Shark - I recently purchased a replacement battery for my Shark RV750 vacuum, and I couldn't be more pleased with the performance. This battery lasts just as long as the original, if not longer, which is a pleasant surprise. It's so easy to install—just pop it in, and you're good to go. The battery charges quickly and holds the charge exceptionally well, allowing me to complete my cleaning routine without interruptions. It's noticeably longer-lasting compared to other replacement batteries I've purchased on desertcart in the past. Overall, I'm very satisfied with this purchase and would highly recommend it to anyone looking for a reliable and efficient replacement battery for their Shark RV750 vacuum.
