Cordless robotic pool cleaners cut the hose tangle and let you drop, swim, and skim without rewiring the deck. This roundup compares Dreame, AIRROBO, UBoter and VONKO across suction, runtime and navigation so you can pick the right battery-powered unit for your pool size.

Overview The Dreame Z1 Pro is a flagship cordless robot built around 8000 GPH suction and a 180–300 minute battery runtime. It handles floor, walls and waterline with smart navigation that maps the pool before plotting a path.
The standout is raw suction paired with usable runtime – 8000 GPH is enough to lift settled silt and small leaves, and the upper 5-hour battery window covers most 20,000–30,000 gallon in-ground pools on a single charge. Wall climbing actually reaches the tile line rather than stalling halfway up.
Secondary wins include smart navigation that avoids the random ping-pong pattern cheaper units use, plus app control for scheduling and zone selection. Trade-off: at $449 it is the priciest of this group, and the larger battery means a heavier lift out of the water.
Pros
8000 GPH suction handles silt, sand and small debris
180–300 minute runtime covers large in-ground pools
Reliable wall climbing up to the waterline
Smart path navigation instead of random bounce
App scheduling and zone control
Cons
Heaviest unit in this lineup to retrieve
Premium price tier
Charging the larger battery takes longer
Best for Owners of larger in-ground pools who want maximum suction and runtime without a hose.
Overview The AIRROBO cordless robot targets both inground and above-ground pools with auto-parking and wall climbing in a mid-price package. Twin drive motors and dual filter baskets keep maintenance simple between cycles.
Value here comes from pairing wall climbing with auto-parking – when the battery runs low it drives itself to the pool edge so you are not fishing it out from the deep end with a pole. For seasonal pool owners that single feature pays for itself.
Cleaning coverage is solid on floors and cove transitions, and the filter basket is large enough to swallow a typical leaf load without mid-cycle emptying. Trade-off: navigation is pattern-based rather than mapped, so very irregular pool shapes can leave small skipped zones.
Pros
Auto-parking at the wall when battery drops
Wall climbing for floor + wall coverage
Works on both inground and above-ground pools
Large top-load filter basket
Reasonable mid-tier pricing
Cons
Pattern-based, not mapped navigation
No companion app
Best for Buyers who want wall climbing and auto-parking convenience without paying flagship prices.
Overview The UBoter E10 is a cordless pool vacuum built around an extended-runtime battery and a dual-layer filter system. It targets owners who want a full clean cycle plus margin on a single charge.
Battery life is the headline – the E10 is tuned to push past the 2.5-hour mark that trips up cheaper cordless units, which means medium-size pools usually finish on the floor and walls without a recharge interruption. That extra margin is what makes it the runtime pick.
The dual-layer filter pairs a coarse basket for leaves with a fine mesh for sand and pollen, so you are not swapping cartridges between debris types. Trade-off: suction is solid but not flagship-tier, and navigation is simpler than the Dreame – fine for rectangular pools, less efficient on freeform shapes.
Pros
Extended battery runtime for medium pools in one cycle
Dual-layer filter for fine and coarse debris
Solid floor and cove coverage
Lighter than premium units for retrieval
Fair $299 price for the runtime delivered
Cons
Suction is mid-tier, not flagship
Basic navigation on irregular pool shapes
No app control
Best for Owners who want the longest single-charge cleaning cycle in the cordless mid-range.
Overview The VONKO P10 is a sub-$200 cordless robot with a 100-minute runtime, sized for both in-ground and above-ground pools. It focuses on floor cleaning with a straightforward pattern-based path.
At this price the standout is simply that it is fully cordless with a usable 100-minute runtime – enough to cover a small to medium pool floor in one cycle, and a clean step up from manual handheld vacuums. Setup is drop-and-go with no hose, no booster pump, no deck wiring.
The trade-offs are honest at $179: no wall climbing, no app, and the pattern logic is basic. For square or rectangular pools under 15,000 gallons that is fine, but freeform pools and waterline tile buildup will need supplemental brushing.
Pros
Lowest entry price for a true cordless robot
100-minute runtime covers small-to-medium pools
Works on inground and above-ground pools
Drop-in setup with no hoses or pump
Lightweight retrieval
Cons
No wall climbing – floor only
Basic pattern navigation
No app or scheduling
Best for First-time cordless buyers with a small to medium pool who want hose-free cleaning on a budget.
