I am a mechatronic (robotics) engineer and I was shocked at how good this little guy is. My apartment has all wooden floors which makes things easy, but this robot vac exceeded my expectations on its mapping of the rooms and being able to find the charging doc. Only drawback is the limited battery life (60mins) which is just enough to do my 2 bedroom apartment (living room, kitchen, hallways + 2 bedrooms). I clean the dustbin after every time I use it so havent had any issues with its capacity. I am going to see if I can buy a larger capacity Li-ion battery (4800 mAh instead of the stock 1800 mAh).

I have PowerBot.... I cant cant replace brush You spend $$$$ but cant even find replacements when you really need them..

I bought this vacuum now 22months ago & have found it fantastic. The price i paid for & what i received exceeded my expectation. I have 2 small children & animals that live inside. This vacuum has been able to keep up with the foot traffic & do a pretty good clean. Sometimes does not find its way back to the charging dock but my house is pretty large so that can be expected. As far as any warranty issues, samsung have been fantastic to deal with. Overall i would highly recommend to friends & family (which i have already done)
