Substantially improved runtime. Itfits without issue. Recommended.

Exact fit. Works well.

Was a perfect replacement and works well after charging up

I've had one of those vacuums for several years and the battery finally started going out on our "Deebot" vacuum. It would just beep and beep all the time and would only run for like 10 min. I bought this battery in hopes it would help me to salvage the vacuum. It was easy to install, once I got it charged up, it's been awesome. It's like my vacuum is brand new again! It will now run for around 1.5-2 hours before needing a charge, which is incredible. This one has a larger capacity than the oem battery as well. Would not hesitate if I had to buy this battery again.

Issue turned out to be with the vacuum brush. The battery is still working fine.

Exactly what I needed for the battery replacement for my Ecovac DeeBot vacuum. It's working like it's brand new once again. This was probably half the cost of my last battery from a local battery store. Considering I run it every single day itis lasting quite a long time.

I thought my Deebot vacuum that sat in storage for 3 years was done for. This replacement got it back up and running!

Only worked correctly a few times. Won't recharge fully.
