Robot Vacuum Replacement Battery

Extremely easy to install, about a 10 minute job including finding the Youtube videos with instructions. Works great. Appears to have improved the cleaning ability (duration) greater than the original battery. Very satisfied so far.

I recently purchased a slightly cheaper battery from Amazon for my Roborock and it was a mistake. After installing it I had all kinds of problems with my vacuum (I kept getting overheating messages, etc.)I have purchased two of these batteries for two different robots and they both work flawlessly.If you are in the need of a battery, this brand has been reliable.

Very fast delivery. I was impressed. Nobody wants to be without their vacuum! The battery arrived safe and sound and went immediately into my vacuum. It fit perfectly. Absolutely no issues. It's only vacuumed once since It arrived but it was good and strong and it looks like it's going to be a very satisfactory replacement.

Battery life is ~90 minutes, which is about the same as the original battery.This is not a 6700mAh. The description is a lie.

Replaced Roborock S7 battery with this. Working great so far.

Its the perfect replacement and gets your roborock s4 and more going back to factory settings.Previously to this, I thought I had an electrical issue as my s4 would randomly die after a couple minutes of cleaning. Even when fully charged, the unit would die until back on the charger.So I figured it was worth getting a new battery and bam, this thing is back to new.Highly recommend.

Picked this to replace the original battery because it was having to charge several times before completing a cycle. After having it for a few months, this one is lasting about as long as the old one. I will probably be doing better research before getting the next one.

Works great. It was easy to install and worked without issues.The vacuum robot can now complete the whole house without having to return to the charger half way thru
