How often do you have to replace the head of this unit?

I think it's however long to actual machine lasts...4000 uses..2000? I'd check on the actual site. I just think the light stops working - which is what you need.

I have never had to replace it that often. Is your water extremely hard? Are there many contaminants in it?

No, you cannot replace the head. As a side note, I use mine for 6 times after replacing the whole roller. Some pages in internet say thst you should use the roller once.

The suggested replacement rate is every six months, but I replace it every three. Using the special covers that supposedly clean the brush while not in use, I find that black spots appear in the brush head if I don't switch it out after about 3 months.

I change mine about every 6 months, but I only use it at work. It doesn't get everyday or all day use.

We have had no problems with ours. We have hat it about 2 months and used it 20 or so times.

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.

Sorry. I've not had to replace mine, yet. That sure is a horrible thought, because I really love my headset. You must really use yours a lot.

I change mine on average every 4-6 weeks. We have moderately hard water and it gets progressively crustier at the top as time goes by; this reduces its efficiency in humidifying the air. You will know this is happening if it uses less and less water even on the high fan setting.

A few weeks, I think they suggest replacing it every two weeks, but I've used it for six weeks with no complaints from my pup. Depends on weather and usage I would guess also.

I have yet to replace mine. And I've had teh unit for a number of years now. I suppose the battery life will depend how heavily it is used. Mine is moderately used.

I'm uncertain about a replacement. It might be less expensive to replace the entire unit. Although, if you go to the company website they may offer one.

I saw replacement heads available for sale on Amazon. Enter the model number on your search.

Same, I haven't needed replacement yet either - in the past, with older models, I've purchased them at Target, Walmart, etc. or I would imagine you can find them on Amazon? Perhaps just Google in the Norelco model number and you should see some results for replacement heads.

Yes. It is time to replace it. I have the same problem now. It is supposed to last seven years.

This head just replaces the old one. All the power connections remain the same.

Every 3 or 4 months. In between I take the head off and clean everything. Stuff gathers inside.
