Lydsto Robot Pool Cleaner S3 review
Cordless coverage for more of the pool.
Robot Current is reader-supported and may earn a commission from qualifying purchases through affiliate links, at no extra cost to you. Brands cannot buy a recommendation. How this works.
We recommend shortlisting the Lydsto S3 if you want one cordless robot to cover the pool floor, walls and waterline. Lydsto lists three cleaning modes, a 15,000mAh battery and up to 180 minutes of cleaning for pools up to 2,000 sq. ft., giving the S3 a clear whole-pool brief. Its US product page was marked sold out at our check, so confirm stock and your pool’s compatibility before planning a purchase.

The quick answer
The Lydsto Robot Pool Cleaner S3 is worth considering when you want a cordless robot designed for floor, wall and waterline cleaning in a pool Lydsto rates up to 2,000 sq. ft. Three modes and a stated 180-minute cleaning run make its coverage attractive. Check your pool’s shape and surface against the manual, then confirm availability: Lydsto’s US listing was marked sold out at our review check.
Why we like it
- Designed to clean the floor, walls and waterline, not just the pool floor
- Three cleaning modes give owners a choice of pool-cleaning routines
- Cordless operation removes a power cable from the pool
- Lydsto lists a 15,000mAh battery and up to 180 minutes of cleaning
- P-Smart 2.0 uses IMU sensing and ultrasonic technology in its navigation approach
Before you buy
- Lydsto’s US product page was marked sold out on October 16, 2026.
- The listing does not detail compatibility by pool shape, surface, depth or steps; check the manual for your pool.
- The page does not describe surface skimming or the filter-care routine.
- The 180-minute runtime and 2,000-sq.-ft. coverage are manufacturer claims, not independent measurements.
Why we like the S3’s broader cleaning brief
A floor-only robot solves one part of pool care. Lydsto positions the S3 for the floor, walls and waterline, which makes it more interesting if brushing those areas is part of your regular routine. Three cleaning modes add useful flexibility. We would choose it for that defined coverage, rather than assume it also skims floating leaves or replaces the pool’s normal circulation and water-treatment systems.
Match the S3 to the pool you own
Lydsto lists the S3 for in-ground and above-ground pools up to 2,000 sq. ft. Treat that as the manufacturer’s stated ceiling and measure the area you want cleaned before ordering. Pool area is only one part of fit: check your surface, shape, steps, ledges and depth against the exact manual. The product page does not break those compatibility details out, so unusual pools deserve a closer look before you choose.
Cordless cleaning still needs a routine
The cordless design means there is no power cable to route across the pool. Lydsto lists a 15,000mAh battery and up to 180 minutes of cleaning, which gives the S3 a useful stated runtime for a larger cleaning job. That figure is a manufacturer claim; the page does not explain how mode or pool conditions affect it. Plan where you will retrieve the robot and recharge it between cycles.
Navigation features explain the intended approach
Lydsto describes P-Smart 2.0 navigation with IMU sensor intelligence and ultrasonic technology, alongside a quad-motor, dual-suction system. That combination is designed to guide a robot through a pool while it cleans multiple areas. We like that the system is built around movement and coverage, not suction alone. The listing does not provide independent route or pickup measurements, so use the product manual and your pool layout to judge suitability.
Plan for care as well as cleaning
A pool robot still needs to be removed, checked and stored after a cycle. The S3’s public product page does not explain filter access or a maintenance interval, so look up the exact manual before buying and make sure the care routine suits your debris load. Keep a convenient dry place for charging, and follow Lydsto’s instructions for retrieval, rinsing and storage.
When to compare the Beatbot AquaSense 2 Pro
If floating debris is a regular problem, compare the Beatbot AquaSense 2 Pro as well. Its Robot Current listing includes water-surface cleaning alongside floor, wall and waterline coverage; Lydsto lists the S3 for those three underwater areas. That makes the Beatbot the broader match when surface skimming matters, while the S3 is a focused fit if your existing skimmer already handles leaves. These are different feature sets, not a head-to-head test.
Our buying advice and the Lydsto code
The S3 deserves a place on the shortlist when its stated area and cleaning coverage match your pool. At our check, Lydsto marked the US product page sold out, so verify availability and the exact US option before planning a purchase. The supplied Lydsto partner offer reports $10 off with code SEBASTIANBASSOL, but product eligibility and checkout savings are unverified. Review the offer terms and confirm the final total before paying; the discount is a bonus after the robot fits the job.
