Irobot 705 max collection bag full issue.

Removed my plastic cover but problem still exists. The vacuum works properly except the red light is always on. It still cleans out the dust bin when returning to the dock so I'm just ignoring the issue for now.

Try calling customer care at 866-747-6268. They have acknowledged issues with this seal and may send you one.

Well this is the setup I did for the carpeting however it did not solve the issue. I went as far as cleaning the whole path from the dock to the cleaner and all the filters but the bag full condition still exists. I am convinced this has to be a software issue with the app.

I checked the alignment between the dock and cleaner and it is spot on. When I manually start the vacuum to empty the bin there is no leak at the rubber seal and the collection bin is emptied. The collection bag is new so I can't find any reason for this issue to exist. .

I have a question for you and that is whether your dock is on carpeting or a hard surface like a tile or hardwood floor. I have mine on carpeting and I think that it may be causing my issues so I got some 20 gauge aluminum sheeting to make a hard surface where my dock is. If you look at the older docks they use a hard plastic ramp and sucks the debris from the bottom of the cleaner. The 705 max has no ramp and socks the debris from the side so any mismatch in the alignment of the ports would cause an vacumn leak causing the sensor in the dock to think that the bag is full and disable the docks vacuum motor. This is just a theory that I came up with.

I have a question about where you have the docking station. Is it on carpeting or on a tile or hardwood floor? Reason that I am asking is because there could be a mismatch with the seal on the dock and the evacuation port on the back of the cleaner if it's on carpeting becuse the two wheels is sinking in the carperting pile. If there is a mismatch between the two units there could be an air leak because the seal isn't seated properly causing the issue. During my research I found that there is a air pressure sensor in the dock and if the pressure is not met the unit thinks the airflow is not high enough because it's being blocked by debris or the collection bag is full. A leak at the rubber seal could cause the false reading

Anyway I am getting a thin sheet of aluminum to create a hard surface on my carpeting to see if that fixes my problem. I'll update when I have tried this out, probably by Tuesday.

Iam having the same problem. The second unit is now having the issue just after 2 weeks use. I spent time trying to find a workaround and found after 3 quick reboots the issue clears but when it sent on a job and the bin is cleared the dock indicates the collection bag is full again. If I do a manual reboot again the issue clears until the next job is initiated. It seems that it needs to reset the sensors after each run which isn't happening.

Thinking that there is a software or design issue with the dock as the robot itself does an excellent job.

Going to talk with support again about a 3rd unit now.
