Was very easy to replace and works great
My Robo sweeper is an older sweeper. I happen to like it better than my newer one. I ordered this battery put it in myself and my old sweeper works just wonderful.

Useful life cycle less than 1 year.
These batteries worked well but after 11 months they are down to 20 minutes of vacuum time. 2 batteries in 2 different Rumbas. Not good enough Note: the company read my review and contacted me. They sent me out 2 new batteries to replace the ones I bought. Changing to 5 stars. This is a quality company that actually cares about their customers. Great job!!

Great Battery Replacement with Excellent Performance
The battery fits perfectly and provides a significant boost in runtime compared to the original. My Roomba can now clean my entire home without needing a recharge halfway through. The installation was straightforward, and it charged quickly. I appreciate the added power, which allows my Roomba to pick up more dirt and debris. The only reason I’m giving it four stars instead of five is that I noticed it takes a bit longer to charge than I expected

It held up for about 4 months cleaning about 500 square feet daily.
We got a replacement battery in February but this week I found poor Roomba in the middle of the living room 3 times already when I returned from work . It didn’t make it back to the charging base . Are these new or refurbished batteries? I thought it would last longer.

This saved my Roomba!
I had a Roomba that I admittedly never used for years. I finally moved into a new home a little less than a year ago and decided to finally set the Roomba up. Unfortunately, every time I ran the Roomba it would go for about 45 minutes then die and say "Please charge Roomba." It made no sense to me, as I read the Roomba was supposed to dock if it sensed it had low battery. I thought there might be interference from objects or the dock was obscured or the sensors were broken. I was ready to give up when I decided to just try to replace the battery and see if that worked. And wouldn't you know it, that fixed it! The Roomba now finished its jobs and docks no problem. Sometimes the Roomba will get stuck, but never because of battery issues (mostly getting stuck under furniture). This was an excellent product that is still running strong a few months after purchase. Even if it stops working it was well worth the cheap price I paid.

It works great
I got this same battery 3 years ago to get my old Roomba going strong again. I read that 3 years is the normal life for the batteries, so I ordered it again. I’m really happy with it and what it’s done for my Roomba.

It is a nice camera but it doesn't stick to the glass, it records a nice picture
The glue that holds the camera to the window glass became like goo, I am using g a small tripod and got good results, the image is very clear and it seems to record well into the card
