what is the life expectancy of model 4210

Maybe a year? Always had issues with mine and I've had two roombas. I wish I would have bought a different brand. Make sure you clean it thoroughly after each use.

I had my Roomba model 4210 for at about 7 years before I gave it away to a friend that was interested in getting one, The only thing I had to replace in the time frame was the battery a couple of times, Other then that it always worked. I purchased a newer model after I have that one away.

If you check the back side of the unit you will see a label which has various pieces of information including a manufactured date. I quite sure you'll find it is probably six or more years old. That being the case, the unit must be replaced. It's useful life has been reached. It is designed to be this way. New batteries will make no difference.

You'll find the mnfc. date on the inside of the unit. The unit will be good for five yrs from that date. My last one lived for almost seven yrs. before needing replacement.

Depends on the manufacture date. Typically, the stuff I purchased had a solid 10 years on it.

This model expires 6 years from date of manufacture. Mine is good til 2018.

I'm not sure, but I believe it was 50,000 hours for the life span. They work GREAT though!

Had it for months now and I think it is supposed to last for years. First time it was changed since bought. That's probably 10 years.

The 10 year is only on the Magitron part of the item. As a whole the item only carries a 1 year parts and labor warranty

I'm not sure of the life expectancy. I would say a couple of years for sure. I am very pleased with this battery. I had previously had a lithium battery. This one holds the charge longer between uses , charges really fast, and allows me to cover larger area per charge!

I just got the same ERR.. message last night. Mine had a manufactured date of 8/9/04 so it was probably a couple months old when I started using it. Almost exactly a 7 year life....amazing!

I've only been using them since Aug 2014 so I don't know their life span. I just know they are the best product for camping and emergencies.

I had 2. One died about a year ago and the other is still going. It will be 26 years old this January. Honestly.

From my experience, the life expectancy is about 2 years. The only reason I keep buying these batteries is because I have several pieces of equipment that uses this battery and I don't want to just throw them away. I have about 4 of these batteries and i keep one in the charger most of the time. I have thrown away about 3 of them in the last 5 years. The battery will do well for about a year and then it will lose it's charge sitting on the shelf. I'm guessing these batteries that we are buying are several years old when we receive them. Sorry to tell you this.

I'm not sure of the year, but it is in great shape. I had one before this for 40 years. Yes 40 years. That's why I never thought I could get another one. It works wellThank you. Ronnie

I had one last about 3 years and I'd say it had at most 40 hours on it. I have others that are still working, but at these prices, there should be absolutely no failures at all - no excuses!

Hi, I've had it for around a year and it is working great. I wouldn't know what is the complete average life of it though.

I don't really know its lifespan. I bought it for couple of years ago but I haven't use it very often and about less than five minutes each time. It does the job good so far (as I expected) but little bit noisy. As for how close it trims, it just like couple of days after shaving the beard starts growing back...
