Question: Does anyone know if this will fit the 595 Pet series sold at Costco?
Document: Perfect replacement brushes for our I robot pet series. East to replace and not a bad price either. Will be buying more.
Good product, fair value for price paid. Item fit the iRobot 500 series as described. I would purchase this item again.
The side brush on my 500 series is barely holding up and needed replacing. The only local store that carries the parts is Bed, Bath & Beyond, but the price turned me off. These brushes fit well and came with extra screws for each side brush. Shipped at a timely manner and was well packed. I would reorder these again!
Needed a replacement for my original roomba side brush. The bristles were almost gone, my poor roomba (500 series) has been working too hard. I'm glad i bought these replacement, they fit well, are affordable and roomba is able to use them to sweep the dirt and vacuum it up again.I would purchase these again if i need them next time!
I purchased because my other brushes kept breaking. These are much more heavy duty and fit the older 400 series. BUT!!! the screw that comes with these DOES NOT fi the 400 series, so you must keep your old screw. I am sure you could jam it in there and make it work, but you better pray you never need to replace because you will strip the only screw you have. That mbeing said, these brushes are also longer, so when it spins it boes hit my wheels, but it is not so long that it could jam itself on the wheel.
This are the same as OEM and they perform the same with out any issues, I recommend this item to anyone.
Absolutely love the iRobot and these side brushes are invaluable. Recommend anyone who is busy and needs an extra helping hand.
When they came out with the pet version, he bought that too. Those little brushes ware out (they get shorter and shorter) after awhile. Those little brushes are  very essential.
the side brushes get quite tangled with hair and pet fur, so having spares is a big help and keeps the unit working effectively.
my old one lasted over 2 years but it was time to replace the brush and these work great. anyone shopping for these knows what a roomba does and how these brushes work. these are legit.
Answer: Yes it's for all 500 series roomba. The costco 595 is the 562 sold by roomba just renumbered
