Replacement Parts for Roomba 500/600/700/800/900 Series Front Wheel/Caster Assembly

I discovered my little front wheel missing from my Roomba and was dismayed. Despite searching the house, I couldn’t find it. I was hesitant to order this part from anyone other then IRobot. Especially, when I discovered I could buy a replacement from them directly. However, the minimum amount for free shipping was high and the cost to ship was about the cost of the part. And, I’m not a patient person. I wanted it delivered quickly. I figured if it didn’t work, I could return it to Amazon. However, this popped right in and off my Roomba went! I hear a slight squeaking noise, but I don’t know if it is from the wheel or something else on the Roomba. It’s not so loud as to be super annoying. Just glad I got this thing working again! Quality product that works. Can’t ask for much more!

Looks like OEM, good replacement for one that wore out on concrete basement floor

fits. works

My original Roomba R3 510, which is over a decade old and it needed a replacement front caster. The old one had worn out and would fall out when I picked up the Roomba. UnitedGene Replacement’s caster was a perfect fit. It's not as beefy as the original, but it's a good fit and I can see it lasting a good amount of time as well.My model number is Roomba R3 510, in case you have a similar model.

This part was so easy to install on my iRobot vacuum. It now glides perfectly around the room. You can beat the price!

My i-robot roomba 770 lost its front wheel last week, so it was unable to successfully dock on the charger. After the front wheel disappeared I immediately placed the order for this replacement, and it arrived a day early...delivered on Memorial Day. This replacement front caster popped right into place, spins beautifully, and for the first time in days, the machine docked itself, charged itself and subsequently ran on schedule 2 hours later. So simple... It's a great replacement caster.

Perfect works like the original part oh, except this one is now clean and smooth and functions even better since the old one became rough and was not gliding smoothly which was wearing on the battery life according to Roomba staff. It is worth replacing this part. Staff also informed me that dirty brushes will limit battery life as well. So I bought new brushes and in fact a new battery since mine was at least 10 years old and things are working like new again.

It works well amd was a “ snap” to install.
