Avaenzo Rechargeable Dual Model Virtual Wall Barrier Compatible for iRobot Roomba 800 900 I/S/E Series e5 e6 i4 i6 i7 i8 and All Plus Versions S9

Get 2 for a cost half what irobot charges and no toxic batteries to deal with monthly. Range of beam is great and smaller size is a plus.

I actually bought some secondhand I Ronot ones that ended up not working. I was dubious about these but they are great. Just got to remember to charge every 3 weeks.

I LOVE that these are rechargeable! SO tired of changing batteries on my previous units and this seems to work well. I admit at first that I thought it wasn't connected because when in use it will have no indicator light... probably to extend the life of each recharge. Still a bit confused if the switch put into the middle is the "off" switch and it isn't labeled. I noticed right away that these are REALLY lightweight and our crazy dogs will bump these over easily but found that they fit perfectly in a half pint mason jar and still work wonderfully! Problem solved! The jar keeps the unit nice and clean too. It came with a charging cord but no power block (wall charger) which is another reason why we are giving it only 4 stars.So pros are...~NO BATTERIES to replace!~Uses a type c charging cord (included) which is common to find in most stores and is compatible with my existing phone cord and wall charger.~Fits perfectly in a half pint mason jar and still works great!~Seems to connect instantly even without an indicator light on while in use...Cons so far are...~Can't seem to figure out if the switch can be used to turn off the unit to save remaining charge...~No power block or wall charger included, just the type c cord...~Better instructions to explain the design would have been helpful...~A weighted base would make it much more stable (but the mason jar trick worked well)I would absolutely buy these again and would tell my friends about them... Will update if the battery life doesn't hold up on these units, but so far it seems like a smart product to have and is WAY better because of the rechargeable feature!!! WAY BETTER!!!!

These Virtual Wall units are sleek, good looking and work very well.Both Halo and Straight-Line settings perform as they should.

Ive had these almost 2 months and they work as expected, my only complaint is the battery life is 2 weeks at most before you have to recharge them or your vacuum will end up in unexpected places. Considering the price difference with the irobot ones, I can live with it.
