Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Go on ebay and buy an older one. They exist. A good portion of Valetudo compatible robots are all based on one general model, the 3irobotix CRL-200S. That's what the Wyze WVCR200S I bought is based on.
The Wyze WVCR200S is one of the "probably fine but tread carefully" robots. Some have been successful in getting Valetudo installed, but there is at least one confirmed case of one ending up bricked. I knew this before I bought mine, that's why I went for the $20 eBay special (which works fantastic, but the battery only lasts 10 minutes). If it ends up bricked, then I'm only out $20; but if it's successful, then I got a screaming deal for a 100% locally-run robot.
Wyze WVCR200S (aka "Wyze Robot Vacuum") I'm actually trying to get it rooted right now. It's being a pain in the dick due to Wyze configuring it to shut off ADB immediately after boot. I knew this before I bought it, which is why I went for the $20 ebay listing, but it's also the only CRL200S-based robot that was sold here in the US. It works perfectly, with the exception of the battery only lasting about 10 minutes. The day I got it, I charged it up and set it loose - it mapped about 60 sqft of my living room before the battery straight-up fucking died haha. I bought four Molicel P30B 18650 cells to rebuild the battery pack - about $5 each. Should be solid once it's rooted and flashed... If I don't brick it first. Heh. Edit: Still haven't gotten ADB to stick. Tried about 80 times (not kidding, `dmesg` counts USB connections...). Went through my PC, made sure ADB was working properly with my Pixel, and that `udev` rules were set appropriately. No luck yet. Gonna try again tonight.
A cheap Wyze bot that I flashed with Valetudo. A big thing that helps is taking the time to make your house robot compatible. Things like using velcro cable ties to get cables up off the floor, finding places for shoes (boot trays, shoe racks, etc) so the robot doesn't suck up the laces, etc.
I have a Wyze robot vac cleaning 3 tines a week and I can't believe how much cat hair it picks up. The dustbin is full every time. It also picks up most of the cat litter the cats track out of the boxes.
I have a Wyze robot vac and I'm amazed at how much it picks up. I vacuum whenever I see spilled cat litter but it still picks up so much.
Wyze was my fav but they don't seem to make them anymore. Eufey worked well but the gears were cheap and they got mechanically loud over time Roborock is highly respected in Reddit, but the mop tank in ours does not dry out as it's completely enclosed. You also can't open that part to air it out. So mop feature is now useless to use. Furthermore, the mop tank makes the vacuum tank and vacuum empty area smaller. So it gets clogged with our rabbits hay. Which is an unusable issue that most ppl won't have however we have not had it on iRobot, eufy, or Wyze. Only roborock The roborock is quietest. But wife likes it the least cause mop function leads to it getting mildew or getting clogged often. The mop also grazes the top of our median pile carpet enough that we won't use in on our white carpet as it drags a wet rag over the top just enough to be an issue over time Roborock is actually our least favorite given it's the most advanced m/newest yet works the least for our use case Also, lidar uses IR lasers. Which I swear our rabbits can see. We can see it scanning via the IR cam on our Wyze camera. We worry it will damage there eyes at its right at eye level. So we don't use it in all areas. And 2 of our 3 rabbits do seem to have eye issues but idk if that from the vacuum or from their past life as adoptions. If you have pets I don't recommend running the lidar ones when they might be in the room
The Wyze one is pretty great. And fairly cheap.
I really hate mine. The hardware is good enough, and I like the 'matrix' mode that uses 2 different directions (not up to the spousal standard of 3 different directions, but still), but the software is absolute crap. You can only have 1 schedule/day, and it's for the entire house, with no options. There's no 'current status', no indication of what path it took to clean the area (because it would illustrate how dumb the algos are, I suspect) My first robovac was a Wyze and I was really crashing on their app being unable to anchor virtual barriers to interior walls, but I'd go back to those weirdly shaped/bisected areas in a flinstant. I'm sure they work well for lots of folks, but I'm not part of that Venn ovoid. I've never *wanted* a tech gadget to break like I do this Shark. We've always loved the uprights and stick vacs from them, but I'm never going near one of their robots again.
3 cats (2 shorthair, 1 longhair) 2 kids (1 shorthair, 1 working toward longhair) 1 kid's SO (very much longhair) 1 spouse (standard-ish longhair) 1 self (shorthair) A couple of weeks into ownership of the Mova P10 Pro Ultra Gen2, upgraded to the tri-cut brush. It's been game changing. Hair tangles burned out the 1st Wyze (daily vac, replaced under warranty, this was where I learned about maintaining the vac), so I was constantly monitoring/cleaning the 2nd Wyze until it died an unrelated death. The Shark (replaced the 2nd Wyze) was easier to remember to maintain because it's software is such a pile of gosa that I ran it manually instead of scheduling, but it's brush assembly was actually more of a pain to 'de-hair' than the Wyze Neither of those was self emptying. The P10 has been wonderful. What little bit of hair collects around 1 end falls off on it own, and is minimal. The few times I've paused the vac to look at its bin before emptying back into the dock, it's got the hair all in there. You didn't ask, but seeing you've got some hard flooring, the mopping action is very nice as well.
I started with a Wyze back when the pre-sold them as being the least expensive bot that used LIDAR mapping. I really hated the way its mapping software forced my 'open air rooms' to have the weirdest geometry. There were also places in certain rooms were it would just get stuck. Just stop. It failed just inside its warranty, and they shipped me another one with no fuss. When that one failed just outside the warranty, I shopped around for a replacement. We have only minor moppable areas, so mopping wasn't a need, but I looked at it as an option. I found a review of a Shark Matrix that commented that it was the first of 3 the review tried that actually cleaned vs streaking, and we've always been pleased with the Shark uprights we've had, so I made the purchase. I would have never expected Shark to be so far BEHIND Wyze. The hardware is fine, and I love the 'matrix' mode that goes back over the room with a pattern perpendicular to the first one (spouse is a proponent of up/down, right/left, angled '3 pass', so this was a big step up in her estimation). But the software is just the gray mound of dirty snow over the burnt out husk of what was once a raging dumpster fire. It's just sad at this point in robovac tech that the only option available in their scheduling is "entire house once a day". I chose to not go with the self emptying docking station. This was a mistake, and there was more manual prep/cleanup to use the mopping function that just mopping the dang floor. I would fantasize about walking by as it was not falling down the steps and give it a nudge, so I could blame a faulty sensor. Spent a little time looking around and ran across JustADad's review series and his glowing praise for the MOVA P10 Pro Ultra. With this vac, I have something that I can define schedules with each room having it's own settings for vac/mop. I don't have to have the dock in the tiled space to keep the carpets dry (the P10 lifts its pads), and I can truly leave the vacuum unattended for vacuuming *and* mopping. There are some caveats for these as I've seen folks with dark/black carpets being seen as 'cliff edges'. I've got a couple of dark brown floor registers that my bot won't cross, and I managed to muck my map up enough with 'detail fiddling' that the bot went crazy for a short time, but a remap fixed that. I really didn't want have to do that, but MOVA's mapping is very fast, and it adjusts dynamically in ways that the Wyze and Shark just didn't/don't. It was so nice/problem free. I'm very *very* pleased with this unit.
