What our customer's say!

"Underperforms. ", I was very disapointed with this product for several reasons: 1) the dustbin is very small 2) the main brush needs to be unscrewed to be cleaned 3) the little side brush is made of a rigid plastic that was about to break after being used only a few hours 4) but the main problem is that this robotic vacuum kept spinning around table legs and bed legs, often 5 or 6 times before getting unstuck, and once even 13 times before I finally turned it off and moved it to another spot. There was obviously something wrong with the software of the unit I purchased.

Overall, this seems to me to be a very cheap and unreliable product. I am unable to recommend this product to anyone.

"Knockoff bites", Don't buy this vacuum -- it is a blatant ripoff of the original Roomba vacuum -- which iRobot has since dramatically upgraded with the Discovery series. You can get a Roomba Red for about the same price, with double the suction and much better reliability.

"Trying it out", I have owned about six original roombas. They all work well initially, but all fail within a month or two. I attribute it to poor quality control. The reason that I have had so many is because irobot is liberal about replacing them while they are under warranty.

Koolvac is supposed to be a knock-off of the original roomba and is being sued by irobot. I have ordered one for two reasons:
1) If another company can make the same thing with good quality control, it would be an excellent buy.
2) If it is almost an exact copy of roomba, between them I will have a way to replace defective parts. My last roomba became worthless, when a simple plastic part became worn. Irobot does not sell replacement parts.

"GREAT vacuum! Exact copy of a roomba!", Well I own a Roomba and got a Koolvac for Christmas from a friend ! It's exactly like my roomba! The battery and charger are the same ! It is like Koolvac took apart a roomba and copied it part for part.... Even the wheels are the same! Performance is the same also! This thing picks up dirt like a tornado ! Looks like I am going to sell my roomba and keep my koolvac !

"A wonderful robotic vacuuum", I am a mother of a 2 year old and wanted a robotic vacuum with less noise. I bought this item from Amazon and I liked it a lot. It is not pricey and is truly robotic. I would recommend this vacuum cleaner for anybody who wants less hassle while vacuuming the floors. Plus the noise is minimal when compared to the non-robotic vacuums.
