Chinese brands have transformed the robotic pool cleaner market. Where traditional brands like Dolphin and Polaris sell corded, complicated robots for $1,000-$3,000, Chinese newcomers like Beatbot, Aiper, Degrii, and Wybot offer cordless, smart-navigation models that are easier to use and often more capable.
This guide helps you choose the right robotic pool cleaner for your pool size, type, and budget.
Cordless vs Corded: Why Chinese Brands Went Wireless
Traditional pool robots require a power cord connected to a transformer. Chinese manufacturers skipped this entirely, building their products around rechargeable lithium batteries and smart navigation from day one.
Advantages of cordless:
- No tangled cords
- Works in any pool shape without cable management
- Easier to deploy and retrieve
- No electrical hazard concerns
Trade-offs:
- Limited run time (2-3 hours per charge)
- Need to recharge between sessions
- Slightly less suction power than corded premium models
For most homeowners, cordless is the better choice in 2026.

The Surface Cleaning Advantage
The Beatbot AquaSense Pro is unique in offering surface skimming — removing floating leaves, pollen, and bugs before they sink. No other cordless pool robot combines surface, wall, and floor cleaning in one unit. If you struggle with surface debris, this feature alone justifies the premium.
5 Tips for Choosing a Pool Robot
- Match to your pool size — underpowered robots leave spots, overpowered ones waste money
- Prioritize wall climbing if you have algae issues — algae grows on walls first, floor-only robots miss it
- Check filter basket size — small baskets fill quickly, requiring mid-session emptying
- Consider your pool surface — verify the robot works on your surface type (plaster, fiberglass, vinyl, tile)
- Read the warranty — Chinese brands typically offer 1-2 year warranties, some with extended options
Maintenance and Running Costs
Robotic pool cleaners are low-maintenance.
| Item | Cost | Frequency |
|---|---|---|
| Replacement filter | $15 - $30 | Every 3-6 months |
| Brush replacement | $10 - $25 | Every 6-12 months |
| Battery replacement | $80 - $200 | Every 2-4 years |
| Annual running cost | $50 - $100 | Minimal |
Compared to weekly pool service ($100-$300/month), a pool robot pays for itself within 6-12 months.
