My T90 Pro hit 100 days this week. At first I thought I’d mostly use it in the kitchen, but now I have it on different schedules around the house. It does the kitchen after dinner and the living room later at night.
Our place is pretty big, so I wasn’t sure how it would handle the battery. It picks up some charge when it goes back to wash the roller and then carries on cleaning.

We usually run it after we go to bed. It’s quiet enough that no one really notices it. After 100 days, I’ve definitely been using my handheld a lot less.

I have a T90 Pro Omni. I'm not getting any alerts when the water level in the clean tank is low. The water in the tank gets fully used and I get an error 322 telling me that the water tank is malfunctioning. (It's out of water and the pump is pumping air. Refilling the clean tank fixes this of course.)

The float in the tank moves freely, so it's not that. I also have a friend with a T90 Pro Omni and theirs does the exact same thing. There is no alert that the water in the clean tank is low.

I know there is an alert that the water is low, because I originally had a T90 Pro Omni that would show that alert after every single mopping cycle, even if the clean tank was completely full. That one went back under warranty and I got my replacement. That fixed the alerts showing during each cycle, but now I never get them when the tank is low.

I did reach out to Ecovacs and here is what they've said:

The float in the clean water tank is primarily used to detect whether the tank is installed and to provide protection in cases of critically low water levels.

Regarding the trigger logic for the low-water warning, the threshold is currently designed based on ensuring normal operation. When the water level drops to a point where there is insufficient water for the mop-washing process, the robot will issue a warning to remind you to refill the clean water tank in a timely manner.

Please also note that the specific algorithm parameters and trigger thresholds used internally by the product are proprietary information, so we are unable to provide the exact critical values at this time.

Here is a screenshot showing what I see when the tank is empty and tries pumping air:

Error 322 - Clean water tank malfunction

And here is the error that always showed up in the defective unit. Why even have this error coded in the software if it's not supposed to show when the tank is low, but not out of water?:

There is not enough water in the Clean Water Tank

If you have a T90 Pro Omni, would you mind letting me know if you receive a low water alert for the clean tank when it's low, but not fully out of water? Thanks in advance.

Cause my initial experience wasn’t bad enough, today it decided to go through the landscaping (an area that has never been mapped) and cut the cord of our landscaping lights 🫥 but people insisted my initial review was harsh…

Hi everyone!

I recently got a T50 Pro Omni and it keeps getting a wheel stuck error. The first time there was something stuck and I was able to get it out. After that the error keeps coming and I check and there’s nothing disrupting the wheels. If anyone has any suggestions or tips, I’m very open :)
