It works great and my vacuum now cleans the entire floor on a single charge.

This is a direct fit for the S7+ vacuum cleaner.My original battery was probably only 50% – 70% effective and the cleaning times were starting to become far shorter – so the vacuum was having to return to charging and then being dispatched again – falling behind more and more.So looked for a new battery, easy replacement – google is your friend – and found this particular battery.I noticed that the very first few schedules of cleaning – approx 30-40mins on medium suction and mop, the battery life showing wasn’t all that great at first. However, it quickly improved over 2-3 uses and now stabilized to full charge and is same as new again. I’m happy!

Inaccurate Product Details
I bought this to replace the factory battery in our Roborock S4 Max.The product details are incorrect or misleading about a few aspects of this replacement battery.1. It’s not a Lithium Polymer. It’s a standard Li-ion2. The weight is not 452g. It’s actually 436g, which is close to the original battery (438g), but still slightly lighter. This leads me to conclude that the energy capacity is nowhere near 6700mAh, and more likely lower than the original battery’s capacity when it was new. Palogreen hasn’t provided any evidence of the higher capacity, nor do they explain what a “50% Speed Up” means.3. The wires to the connector are a smaller gauge and the back of the connector is not sealed (compared to both the product page pictures and the original battery.It still blows my mind that Amazon lets vendors get away with misleading customers like this. I probably won’t buy form the Palogreen Store next time.I will update my review after a few months of daily use. Only time will tell if this battery is any good.

Does not last – less than 6 months
Bought in November 2023 and it’s already losing charge quickly. Disappointed

Works great in Roborock S5
My Roborock S5 was shutting off after just cleaning for 10 min or so. It did not provide any warnings about a faulty battery, but I decided to give it a shot. This battery has made the vacuum work almost like new and it can now complete full cleaning cycles. Happy with this replacement battery.

Great replacement for old s7 battery
I’ve had my roborock S7 for 2 years and the battery isn’t lasting as long. My S7 will only clean on max for 31 minutes. I replaced the battery with this one and I just ran it for 80 Mins on max for the very first test. It’s a great replacement. I don’t think it’s better than the original factory battery but now it’s lasting as long as the s7 did when it was new.

Worked perfectly
Our vacuum was starting to die fairly quickly, and we replaced the battery pack and it now runs perfectly once again
