Perfect replacement!

I was afraid that my 2-year old vacuum was on its way out, but upon replacing the battery, it works great again.

Ordered this battery August 21, 2025. It is already not charging as of September 25, 2025. I only run my iRobot every 2-3 days. Don’t waste your money.

So I’ve had a deebot n79w and for a while now it wouldn’t vacuum for too long. and would do rounds of beeping few hours later. which was annoying. one time I vacuumed too late at night and this thing beeped for a minute at like 1am to let me know. I read it meant that the battery needed to be changed. which made sense since it was only cleaning for maybe 30minutes. ordered this new battery, and it came and today is day 2. the vacuum worked for about over 1 hour and 35min. so total of over 100minutes. before it went back to its charging station. and no more annoying beeping hours later! I hope battery stays efficient for a while.

Very affordable not like 15 years ago

Long lasting. Great replacement in my eufy vacuum.

Initially given 5 stars, then downgraded to 1, now giving 3 stars. Looks like my deebot died and not able to charge. So at this point, I don’t know if it is the battery or the equipment itself. So changing my ratings to 3, as it worked for a while. Please find my previous comments below Updated comments: Don't waste your money. It lasted only 2 months and a few days. Just about the time return window was closed. Original comments below,,,, Better than original battery This one is better than the original battery. Each recharge gives close to about 1 1/2 hour to 2 hour runs. When you search for the Deebot N79 replacement battery, AMAZON always pops up a knock-out brand first. Unless and until you specifically look for this, you might end up with a bad one.

It was easy to install and has my deebot working like new. Cleaning lasts 1 hr n 45 minutes
