iRobot Roomba Authentic Replacement Parts - Dual Mode Virtual Wall Barrier Compatible with Roomba 600 700 800 900 Series, Black - 4636429

These things work like a champ, and I love 'em

Works great

Great replacement Roomba barricade. Our original ones stopped working and these work perfect.

Update: this sensor is different than my other and I literally had it backwards. Learn from my pain, the top of the sensor has a side with a line on it, make sure that line is pointed towards where you want the sensor to block. I feel like a dunce but at least it works now. Original review: I got this for Christmas and after the first few times the roomba just strolls right past it. I replaced the batteries and the light goes on but it makes no difference.

Love this. Should have bought this long ago. I have one already but sometimes need to block off other areas. So now I can keep the "Rosie" under control.

bought an e5 (5150) Roomba to clean the downstairs area, mainly the kitchen. we placed the main unit in the kitchen/dining area as it is the room that needs the most cleaning. however, we found that the e5 Roomba did a poor job of properly cleaning the downstairs area. it kept bumping around through all the downstairs areas randomly, missing many spots in the rooms. we were planning to return the robot because of that problem, until i found this barrier. i bought 2 of these barriers so as to section out the downstairs area and help the roomba focus on one small area at a time. i placed these barriers (virtual wall mode) in a way that the roomba could not leave the kitchen area. in this way, the roomba can only bump through the kitchen area (a much smaller area than it would cover without the barriers in place) and give it a proper and full clean. if i want it to clean the other downstairs areas, i simply lift the roomba over the barrier and place it in that area to give that a chance for a full clean (making sure to collect it later as the barrier will prevent it from going home to its base!). one note, when using the virtual wall, make sure nothing is blocking the path of the barrier's beam as any blocks will allow the roomba to slip through and cross into unwanted territories (once a family member had been standing in the path of the barrier's beam and the diligent little roomba happened to be right by the border at that moment and was able to cross behind their leg and into the next room) assembly and use is easy. install the batteries and then slide the switch between 2 available modes. pick a mode and the light will flash briefly and barrier will be good to go. roombas are expensive and top of the line models with room mapping (that allows for a laid out, full clean) are way more expensive and this barrier helps kind of rein in the random bumping of the cheaper models and give a better cleaning experience. wish that the barriers could be linked to the app in the same way as the roomba just for a smoother experience but its not big deal.

Works perfectly.

I don’t know how functional this product is yet, because we are still trying to remove the sticker! It clearly shows to remove it, on the label itself, but it does NOT come off. We tried acetone on the bottom to see if it would mar the finish and it does. It is ridiculous, there is a lot of sticky stuff on the outside of the unit still. I almost want to return it to see if another until will be easier to peel.

perfecto, funciona perfecto los compré de repuesto porque no sabemos qué pasó con el que teníamos, funciona excelente con mi roomba original. Compré dos y ningún problema.

Fonctionne très bien. Facilite le vie

Hace lo que debe.

Moins cher qu'en magasin. Fonctionne parfaitement

Easy to use, but does not work with older Roomba model.
