Review: Works well - The shipment was fast, the installation was straightforward, and the charge lasts much longer. I can vacuum the full floor (~1100 sq) in one go, rather than two. I am pleased.
Review: S6Max V - After 3 or 4 long faithful years of no issues with our Roborock, it kept dying while the charge was still decent, and we had to carry it back to the docking station. We proceeded for about a week and broke up the schedule to not do multiple rooms at once, but alas the battery kept getting worse. So far we have only had this for a couple of weeks but it completely fixed our battery issue. I am super pleased! I heard it was easy to install but I leave that to my man. I hope this lasts another few years. I love my roborock!

### ⭐⭐⭐⭐⭐ S6Max V
*by A***R on January 26, 2024*

After 3 or 4 long faithful years of no issues with our Roborock, it kept dying while the charge was still decent, and we had to carry it back to the docking station. We proceeded for about a week and broke up the schedule to not do multiple rooms at once, but alas the battery kept getting worse.

### ⭐ Nowhere near OEM quality - 66% of claimed capacity
*by P***R on January 20, 2025*

I have S4 Max I bought ~3.5 years ago. Battery has degraded to the point where it will leave two bedrooms uncleaned and go to base to charge before completing the cycle. I installed this battery, left it to charge over night, and next day at 1:30pm my vacuum wouldn't clean one of the rooms and went to charge instead. So I decided to fully charge the battery with lab bench power supply and test its capacity. With discharge down to 3.0V per cell at 2.0A of current it scored 4.4Ah. So it has ~66% of claimed capacity. Additional problem is that the vacuum won't drain battery down to zero during cleaning as it wouldn't be able to come back to the base to charge otherwise. I noticed that S4 will go charge when it reports <20% capacity remaining, and battery will have around 3.7V per cell at that point. That means that even with this capacity, voltage drop is big enough so the vacuum can't clean my whole floor on one charge. Any my house isn't that big - app reports around 55m2 or almost 600 sq ft. When original battery was new, I could set it to clear whole upper floor (55m2) and then carry it downstairs and clean additional ~30m2 (300 sq ft) without charging in between. Good thing that I can return it and get my money back. Maybe I got unlucky, but it's time to try another brand.
