Can I leave my robotic pool cleaner in the water overnight?

I just got my first robotic cleaner and it’s been awesome so far, but I’m wondering if it’s okay to leave it in the pool overnight. Some people say it’s fine, others say to pull it out every time. What do you guys do? Does leaving it in the water wear it out faster?
 
I usually take mine out after each cleaning session, but occasionally I leave it in overnight if I know I’ll run another cycle in the morning. The biggest thing is checking what your manufacturer recommends some cleaners can handle it, but constant submersion could wear out the seals faster. I also like to rinse the filter basket and give the cleaner a quick rinse to get rid of any pool chemicals.
 
I leave mine in overnight all the time during the summer when I’m running the pool daily, and so far it’s been fine. I just make sure to pull it out at least once a week to clean it and check for any wear. I do think leaving it in 24/7 during the off-season or without use could shorten its life a bit, but for regular use, I haven’t had any issues.
 
I usually go by how often I’m using the pool. If it’s been a busy week with a lot of debris, I’ll let the cleaner stay in overnight and grab it the next morning. But if the water’s already looking good, I’ll take it out once it's done.

What I noticed is that leaving it in too long sometimes leads to the cord getting a bit stiff or tangled, especially in warmer temperatures. So now I just try to find a balance, not too paranoid about pulling it out right away, but also not letting it live in the pool either.
 
I like to think of it like my pool cleaner is having a little overnight spa treatment, just soaking in the water and getting ready for the next day’s cleaning. But honestly, I also worry about it turning into a pool floatie if I leave it in too long!
 
I’ve found it depends a lot on the pool's chemical levels and how often the cleaner is running. I used to leave mine in overnight more often, but after noticing a bit of discolouration on the plastic housing over time, I’ve started rotating it out more regularly.

Now, if it’s finished a cycle and I’m not planning to run it again within 12 hours, I take it out, rinse it, and let it dry under the patio cover. Seems to help keep both the motor and casing in better shape longer.
 
I actually call it my robot’s beauty sleep leave it in all night, and by morning it’s fully recharged and dialed in. Just pop it out, rinse the filter, and it’s ready for another day of pool pampering!
 
I’ve tried both, pulling it out right after a cycle and letting it stay in until the morning, and honestly, I think it comes down to habit more than anything. If I know I’ll be running it again within 12 hours, I don’t bother hauling it out. But I always make sure it’s not sitting in there for days on end, especially in peak sun, since heat and chemicals together can be rough on the plastic and seals.

One little trick: I started draping the cord in loose loops over the coping when I leave it in overnight. It keeps it from getting that memory coil twist, and the next run is a lot smoother.
 
I like the idea of giving it a little "spa time"! I usually pull mine out, but on days I’m in a rush, I let it chill overnight. I just make sure to rinse it before the next use. Anyone else find that leaving it in the pool actually saves them a bit of time for the next cleaning?
 
I used to wonder if I should pull the robot cleaner out every night or not. After trying it, I found that if the pool isn’t too dirty, I just leave it overnight, but I always make sure it’s not stuck in a corner or blocked by something. It’s so much simpler now, I don’t need to rush to take it out. But don’t leave it too long either, as it can make the cord stiff after a while.
 
I’ve gone back and forth on this too. At first I pulled mine out after every run because I didn’t want to risk the chemicals or constant water exposure damaging it. But after a while I realized it’s not always practical, especially if I know I’ll be running it again the next morning. These cleaners are designed to be water resistant, but I think the bigger issues come up if you leave them submerged for days at a time without a break, seals, plastic housings, and even the cord can wear faster that way.

What works for me now is kind of a middle ground. If I’m running back-to-back cycles, I’ll let it stay overnight and deal with it in the morning. But if it’s done its job and I won’t need it again for a day or two, I take it out, rinse it, and set it in a shaded spot to dry. That seems to keep the parts in better shape long term while still being convenient.

So I’d say overnight here and there isn’t a problem, but I wouldn’t make it a “live in the pool” situation 24/7.
 
I usually take mine out after each use, but if the pool has a lot of debris and I’m busy, I leave it in overnight and grab it in the morning. Just make sure the seals aren’t worn out, and during the summer, I tend to leave it in overnight more often.
 
I don’t usually take my robotic cleaner out every single night, but I also don’t leave it in the pool permanently. Leaving it in overnight now and then is fine, especially if you’re running it again the next day, but letting it sit submerged for days can wear down the seals and plastic over time.

What works for me:
  • After each cleaning: I rinse the filter, shake off debris, and leave it in the shade to dry if I won’t use it again soon.
  • Overnight stays: If another cleaning cycle is coming up the next morning, I leave it in the pool but make sure it’s free of debris and the cord isn’t tangled.
  • Weekly check: Inspect the brushes, tracks, and housing for wear or salt buildup.
Basically, a little overnight soak is fine, but treat it like a guest, not a permanent resident, and it should stay in good shape for years.
 
I used to wonder about this too, and what made the difference for me was noticing how the weather and pool use affected things. On really hot days or when chlorine levels are higher, I avoid leaving the cleaner in overnight since the extra exposure seems to be tougher on the plastic parts. But on cooler evenings or if I know the pool is being used heavily the next morning, I don’t mind letting it stay in until I’m ready to pull it out.

The main thing I’ve learned is not to treat it like a “set and forget” gadget, giving it a quick once-over and letting it dry out in the shade every so often goes a long way in keeping it running smoothly.
 
I leave mine in overnight sometimes, especially if I know I’ll run it again the next morning, and I haven’t noticed any issues so far. The key is to make sure it’s free of debris, the cord isn’t tangled, and the filter isn’t clogged. I also try not to let it sit submerged for days on end, since constant water and chemicals can wear out seals and the plastic housing over time. A quick rinse and some shade drying every now and then keeps it running smoothly for me.
 
I used to be super cautious and pulled mine out right after every cleaning, but honestly, that got old fast. These days, if it’s late and I know I’ll be running it again in the morning, I just let it stay in overnight. I haven’t seen any issues doing that, though I do make a point to rinse it off and let it dry once or twice a week.

One thing I noticed, if your chlorine levels are high or you’ve just shocked the pool, definitely take it out. The stronger chemicals seem to fade the plastic quicker. Otherwise, a night here and there won’t hurt it. Just don’t let it turn into a permanent pool ornament!
 
I usually take a middle-ground approach with mine, leaving it in overnight now and then is fine, but I wouldn’t make it a habit. If I know I’ll be running it again the next morning, I just let it stay in and pull it out the next day to rinse and dry.

The only times I’m strict about removing it right away are after shocking the pool or when the chlorine level’s high, chemicals can fade the housing and wear the seals faster. A quick rinse and some shade drying every few uses really help it last longer.
 
I kinda go back and forth on this. At first, I used to take my cleaner out right after every run because I was sure the chemicals would wreck it. But honestly, after a few months, I started leaving it in overnight now and then, and it’s been totally fine.

What seems to matter more is how strong your chlorine levels are. If I’ve just shocked the pool, I definitely pull it out. Otherwise, I just let it sit and grab it the next morning. I still give it a quick rinse and clean the filter before the next run. It’s more about habit than anything, I guess.
