Zima Pro
A pool robot that tows its battery in a float on a short cable and maps the pool with ultrasonic sensors. It promises long runs and app control, but only one short hands-on test exists, and Degrii's store no longer sells it.
See the alternatives below, or switch market.
The short version
The Zima Pro is the first pool robot from Degrii, a young brand that launched it in 2023 and has since sold an upgraded version. Its trick is the battery: instead of sitting inside the robot, it floats on the surface in a separate unit joined by a short cable, which also carries the Wi-Fi and Bluetooth signal. That keeps the robot lighter, and lets the app talk to it while it's under water. Ultrasonic sensors let it plan a route, and it cleans the floor, walls and waterline.
The catch is evidence and availability. The one hands-on account is short and mostly describes features. Degrii's online store now sells only spare parts for it, and the product page just offers to email you when it's back. Degrii has since added the Zima Lite, which it also describes as ultrasonic-mapping.
Our take: Hard to recommend while it's this hard to buy and this lightly tested. If you find one, it suits someone who wants app control and scheduling without an underwater signal dropout, and doesn't mind a float and cable trailing across the surface. For a cordless robot with proper testing behind it, look at the WYBOT C2 or the Aiper Scuba X1.

What we know so far
Limited evidence Only one independent, finished hands-on review so far. A score and badge appear once there is a second.
There's very little independent evidence. The only hands-on account we could verify is from GiGadgets, a tech blog that used a sample of the 2023 original in a small family pool. It found the battery lasted three and a half hours on average and the app easy to use, but it says little about how clean the pool got. Nobody has tested Degrii's upgraded version. Another write-up we found was sponsored by Degrii, so we haven't used it. Everything else here comes from Degrii.

A battery that floats
Degrii puts the 10,000mAh battery in a float on the surface, joined to the robot by a short cable that also acts as the aerial for Wi-Fi and Bluetooth. GiGadgets liked that it follows the robot around and keeps the app connected, which many rivals can't do under water. The trade-off, which nobody has tested, is whether the cable tangles on steps, ladders or corners. Degrii insists it isn't a mains cord, just a link to the float.
Long runs, one measurement
Degrii claims up to three hours on the floor and two and a half on the walls, covering up to 5,000 square feet on a charge. GiGadgets measured an average of 3 hours 32 minutes, beating the figure it had been given. That's a single test on the 2023 version, in a small pool. Nobody has timed the upgraded model, or measured how long it takes to recharge.
App control and pick-up
The app picks floor, wall, whole-pool or manual cleaning, sets schedules and shows the battery level, per Degrii. GiGadgets found it simple and liked scheduling runs for when nobody was swimming. When the battery runs low, it parks against a wall, and a lift button in the app sends it up the nearest wall to be collected, per Degrii. GiGadgets describes the same features but not how reliably they worked.
The one hands-on account covers the 2023 original. Degrii's upgraded Zima Pro is untested, and Degrii's own store no longer sells either version.
Before you buy
The questions people ask about this one
Is it cordless, and how long does a charge last?
Sort of. There's no mains cable, but the robot is tethered by a short cable to a floating battery unit, per the specifications. Degrii claims up to three hours, and GiGadgets measured three and a half on the 2023 version. The upgraded version is untested.
Does it climb walls and clean the waterline?
Degrii says it does, with a wall mode and a whole-pool mode, per the specifications. GiGadgets repeats that claim but didn't report on how well it scrubbed the walls, so treat it as unverified.
Does it need an app?
You can pick a mode with a button on the float, but schedules, manual steering and the lift-to-wall command are in the app, per the specifications. GiGadgets found the app simple and the connection better than rivals that lose signal under water.
How do I get it out of the water?
It parks against a wall when the battery runs low, and a lift button in the app sends it up the nearest wall, per the specifications. GiGadgets describes both features but doesn't say how reliably they worked. Nobody else has tested it.
Compare with
C2
A cordless robot that cleans the floor, walls and waterline and parks at the edge, and two testers found it simple and effective.
A third tester found its suction weak.
Scuba X1
Testers agree it's good on floors and fine dirt, and it charges on a dock.
Testers disagree on how much bigger debris it leaves, and the fine filter is a chore.
Scuba S1 2026
A simpler cordless wall-climber, and EFTM settled into a practical daily routine with it.
PCWorld kept finding whole patches of floor it never visited.
