What reviewers found

Beatbot AquaSense 2 Ultra

  • The Pool Nerd: Named best cordless pick in its 2026 roundup but still labeled it Pool Nerd Disapproved, citing mesh filtration at flagship price and the daily charge and haul routine. The site prefers corded robots and earns affiliate commissions. Source
  • Reviewed: Did an excellent job on bottom and sides and left clear water, but could not clean the shallow tanning area or Baja shelf, lost Wi-Fi underwater, and its near 30 lb weight was hard to haul. Source

Dolphin Quantum

  • The Pool Nerd (5/5): In a head to head with the Beatbot AquaSense 2, emptied the large basket about once a week on the weekly timer, left the floor noticeably cleaner after one pass and the water clearer with NanoFilters. Called it the stronger robot of the two. Source
  • Poolbots (retailer review): In a test pool with algae and sludge at the waterline, a run of about 2 h cleared debris and improved water clarity. The cartridge was full of twigs, leaves and acorns after the run. It scrubbed above the 2/3 wall height cheaper robots reach. Source
