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

works well

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.

This device sends a signal to the roomba vacuum from cleaning where there are cords that the vacuum can get tangled. Works perfectly. Reasonable price.

Works with my iRobot 694. The beam is shorter than I would like.

It’s great to have an extra barrier when you’re having Roomba clean!

Liked the special price on this item. Got two for the price of one.

I have bot been able to set my IRobot for individual rooms yet. But I gave a very large living/dining room (open floor plan). The doorway to my family room is a 10 foot archway and one of these effectively blocked it so the roomba remained where i wanted it. Also, there us a 6 foot doorway into my kitchen. Same thing. They are little but they are mighty. Great product.

I use the straight beam function to keep the vacuum contained within smaller spaces of large rooms to assure that everything gets cleaned. They are also effective to keep the vacuum in (or out) of rooms without doors. So far, they have worked 100% of the time. They seem to have a fairly narrow beam spread since the vacuum will approach the beam pretty closely before it is turned back. This makes it easy to clearly define the area to be avoided. The only downside, to me, is that the devices are overpriced for what they do. I think they are no more complex than a simple remote control device.

Excellent purchase. They work great. Happy with the delivery & my purchase.

It does a awesome Job ,What I like is it goes back to is charging station on it own too recharge it selfAWESOME

El producto funciona con una Roomba modelo 671, delimita el paso ya sea en el switch hacia arriba en linea recta y hacia abajo en un area circular, usa dos baterías AA incluidas, lo que me parece excesivo es el costo son unas mini cositas de menos de 10 cm. de altura y no pesan nada. Por el precio esperaba algo mas robusto, deberían costar menos de la mitad y eso que las conseguí en una promoción. Si son muy útiles.

I bought these sensors for my iRobot. They work great at keeping my iRobot from entering certain areas. Great product and great price. I would recommend it for anyone that needs to control the IRobot movements

Esta ok.
