No item and no money, very bad

I purchased the PowerExtra replacement battery for my 531 Roomba in 2022. Battery life was very good until about nine months ago when I noticed that the the charge began to gradually decrease the runtime. Until then, I was quite happy with the battery. Now, the battery no longer holds a charge beyond 5 minutes. i've owned a Roomba since the first model was introduced so know how to properly use, clean, and charge a Roomba to preserve optimum battery life. Maybe my expectations were too high, but I was disappointed that this battery didn't last longer.4/2024 As an update, I decided to try another battery from this company after writing the earlier review and having received excellent and courteous customer service. I'm updating the review from a 3 to 5 stars. The new battery is working great, running about 90 -100 minutes on a charge. Soon I will buy another one for my very old 400 series Robot. I'm glad that these aftermarket batteries exist as the iRobot batteries are too expensive. Have used Roomba vacuums for about 20 years.

Hasta ahora funcionando muy bien

Runs the full hour then makes it home every time and shows green light the whole while. Very impressed and installs quickly

This was a very affordable option for my Roomba. It arrived quickly, was easy to install, and had my Roomba up and running in no time at all. It has given it a new lease of life which is awesome

Works great, charges well and cheaper than the roomba brand battery
