A low cost cordless robot that The Hook Up named its budget pick for sand, silt and pollen, thanks to the 3 micron inner filter and good waterline reach. Its bin is small, it skipped steps for one reviewer, and it ran about 2 hours in testing rather than the claimed 3. Pick it for a lightly leafy pool on a budget; skip it if your pool collects lots of leaves.
Best for: budget pools with sand or pollen. Skip if: your pool fills with leaves.

What independent reviewers found
- Ran 2 h 9 min and covered 99% of the floor, 81% of walls and 38% of stairs and bench. Reached the coping at the waterline, captured silt well with the floss filter and leaked zero particles, but has a small bin and climbed the 8 in shelf enough to raise concern it could climb out. Named budget pick for sand, silt and pollen.
- The Hook Up
- Cleaned the test pool spotless in about 90 minutes and climbed walls and a two tier step. Charging from 5% to full took 3 h 40 min. Flipped upside down once after a wall climb.
- EFTM · 87%
- First clean of a week old pool took about 2 h. Floor cleaning was consistent, wall climbing less so, it did not clean steps, and the app lost Bluetooth underwater. Weighs around 10 kg.
