Same problem here.
Added some aluminum foil between the 3d printed part and the sensors, doesn’t appears to be the root cause. Am also able to carry it and have him keep spinning his wheel.
After taking a video, it just appears to hate large area rugs.
I put electrical tape over my cliff sensors but that only made the vacuum think the wheels werent touching the ground, so the vacuum did nothing.
It’s absorbing too much IR, it needs to be reflected back. I’ve seen just laminating some white printer paper with packing tape on one side is enough to do the job. Not sure if the tape is placed on the inside or outside.
I was thinking maybe the firmware changed the sensitivity of the cliff sensors, but now you’ve bypassed those. Hopefully the bump sensor isn’t acting up. How thick is the throw rug?
I could probably find some things to test on mine, but I don’t have the update yet. I have the early multi-floor beta still.
Here’s a test… while it’s working properly in a flat area with no throw rug, see what happens if you press down the back/front end. Try to simulate it climbing or bouncing and causing the lidar angle to change.
Mine is not working correctly on any floor surface at any time, unless it is quick mapping or traveling to a location to begin cleaning. Once suction begins, the vacuum makes strange, erratic movements. I’m done spending time with this broken machine that didn’t even last 1 year.
I would set it aside and keep an eye out for future firmware updates. Note, my last reply was to bshot1 since his seems to work fine on bare floor. What’s odd is you’re both on 202, I wonder what’s different with the hardware.
You said it worked fine until Mar 16, did yours originally come with 202? (You mentioned doing a factory reset and it remained at 202.)
@OUACWS
It’s like the firmware is failing to detect that the two ends have met and and that it’s stuck in perimeter sweep mode. Are you also on 1.6.202?
yes I am. I believe it started the first time I used it after the firmware update.

It would seem 202 is just borked.
Rug thickness tested with a caliper is ~10mm (uncompressed).
Been busy the last few days. I have the luxury of borrowing a newer wyze vacuum to get an idea if it’s just me or what.
While the newer vacuum eventually worked fine, it did get stuck in a loop after the first mapping (It would continuously vacuum the entire floor over and over until directed to go back to the charger or until it ran out of batteries).
I tried pressing down on the old vacuum to see if I noticed anything, but not sure what I’m looking for. Vacuum didn’t seem to notice.

10mm sounds fine to me. Firmware version of the newer vacuum?
I’m going to see what I can do to mine.
1.6.202

Joining the thread, 202 screwed it up for me too.
Just like you guys, the vacuum will come off the dock and try to figure out where it is in the room. Nonsensical circles is the best way to describe it. It goes all over the house though but if you notice in the app, the green dot thinks it’s still on the dock. After a couple minutes, it says “can’t find location, starting to map and clean the entire floor” and it tries to re-map the entire house.
I can delete the “new” map, load the correct one, put it back on the charger, and the whole process starts over from scratch. I want the old firmware back!

Purchark, thank you for trying to help us with this. Do you work for Wyze? If not, then it’s quite obvious how useless Wyze customer support is. What a shame.
No, but you can see who does if they have “Wyze Team” by their name.
The Wyze forum is mainly a community support forum. I usually try my best to avoid official support channels so I have little experience with Wyze’s.
Mine has started doing some weird/similar things too lately and I’m still on the year old beta firmware.
Just carpeted floor, nothing has changed in this area.
One the tests I’ve done recently is to see how sensitive the bumper is. Just the slightest touch with no noticeable deflection was enough to trigger it.
I don’t hear any clicky sound, maybe it’s optical or magnetic, that would leave some opportunity for interpretation by the firmware. If it is optical, it could be affected by dirt.
More tests bumping the bumper was not causing it to avoid an area, it just does some circles and comes right back to the same area.
I was able to easily cause it to avoid an area by placing my hand in front of the robot without touching it…
Gave the LIDAR unit a quick blast of air just in case.
I’ve figured out a relatively simple yet effective fix for anyone with robot vacuum issues - Purchase a new one (I got mine from Walmart . com) and return the old one. The vacuums dont appear to have any serial numbers, so it’s an easy swap. My old vacuum (and many others) became useless with update 1.6.202. The new vacuum came with 1.6.113, and the update being offered on the app is 1.6.199. So obviously Wyze knows theres a problem with the 202 update, but offers absolutely no fix for it. They haven’t bothered to mention that a fix is needed, let alone release one. A simple option to revert the firmware back to an older one would probably solve the problem as well. But instead they choose to ignore us - so our best option is to buy a new one and return the old one for a full refund.
I’m having the same issue where the vacuum can’t figure out where it is. Nothing has changed in my room, there aren’t any boxes or anything on the floor that could be confusing it. It leaves the charging dock and wanders all around the room. Not all the time, maybe 30-40%? Sometimes I pick it up, move it to a hallway, and let it restart. It usually can figure out where it is in the hallway.
But it did something last week that was particularly frustrating. In the middle of vacuuming the living room, it suddenly didn’t know where it was, then it deleted its map and said it needed to remap the house. I have kids – remapping the house is a huge ordeal, because we have to pick everything off all the floors, all the toys, boxes, stuffed animals, etc. so it can get a pristine mapping. Otherwise, in the future, it will loop around imaginary toys and boxes.
I don’t remember the vacuum ever getting lost so easily or deleting its map so quickly before. I think that behavior started with this last firmware update. I’m on 202.
I used to love this vacuum, and recommended it to people constantly. But now I seem to recall Wyze stating that they are focusing on cameras pretty exclusively, so it seems unlikely that new firmware updates will arrive to improve our buggy vacuums. Of course the company needs to do whatever it can to survive, but I’m pretty disappointed in how this was handled.
