Can a pool robot stay in the pool overnight?
Short answer
Now and then, but don't leave it in for good. Aiper says an occasional night or a two-day stretch is generally fine, while Beatbot advises taking its robots out after every cleaning cycle. Both say chlorine and sun wear down seals, plastic and brushes, and both say to take the robot out before you shock the pool and wait until chlorine is back in range, which Aiper puts at about 24 hours.
Which robots can do it?
- Beatbot AquaSense 2Yes
The AquaSense 2 parks above the water when it's done or the battery is low, and you can call it to the surface from the app.
Good to know: Beatbot's FAQ says to take the robot out after each cleaning cycle rather than leave it in the pool.
- Aiper Scuba X1Yes
The Scuba X1 has an app-only scheduled mode that cleans the floor for 50 minutes every 48 hours until the battery runs down, and Aiper says an occasional night or two-day stay in the pool is generally fine.
Good to know: Schedule details from PCWorld's 2025 review; Aiper's advice is general, not for the X1 by name, and it warns against leaving a robot in permanently. The X1 parks near the wall but can't lift itself out.
- Beatbot Sora 70Yes
When it finishes or runs low, the Sora 70 floats to the surface and moves to the pool edge, so you can lift it out without fishing in deep water.
Good to know: Beatbot's FAQ says not to leave its robots in the pool constantly and to take them out after each cleaning cycle.
Why it matters
Lifting a wet, heavy robot out after every run is the chore people bought it to avoid, so many would rather leave it in the water until next time.

How much shorter a robot's life gets if it lives in the pool, and whether leaving it in voids the warranty; none of the pages we read gives a figure or a warranty rule. We found no guidance from Mova on the Rover X10.
How we know (5 sources)
Christopher Null's Aiper Scuba X1 review (read Oct 27, 2026): an app-only scheduled mode runs the robot for 50 minutes, floor only, once every 48 hours until its battery runs down. When it's done, the X1 parks near the wall but can't lift itself out, so you use the included hook and a pole.
Read the sourceBeatbot's robotic pool cleaner FAQ (updated Jan 25, 2026; read Oct 27, 2026): it's not recommended to leave the robot in the pool constantly, because long submersion wears parts faster and exposes it to chemicals; take it out after each cleaning cycle. After shocking, wait until chlorine is back in a safe range, since shock chemicals can damage plastic and rubber parts. Refers to the AquaSense series in general.
Read the sourceAiper blog on leaving a robotic pool cleaner in the water (posted May 8, 2026, updated Oct 22, 2026; read Oct 27, 2026): an occasional night, or a two-day stretch, in the pool is generally fine, but manufacturers advise against leaving one in permanently, because chlorine wears down seals, the shell and brushes and UV degrades plastic. Take the robot out before shocking the pool and wait until chlorine is back in range, usually about 24 hours. No Aiper model is named in the article.
