Lydsto Spa S1 Lite Vacs Tested: Amazing Versus Manual Pool Duty… We were intrigued by the Lydsto S1 Lite’s sleek silver design, promising efficiency for small debris in spas. The 90-minute runtime suited our needs, and the 20W brushless motor delivered surprising power for its size. With three aluminum poles, maneuverability was effortless, allowing us to cover both depths and surfaces without strain. The handheld vacuum’s lightweight construction made cleaning jets and tight spots a breeze. While it excelled at fine debris, larger clumps left us wishing for a bit more suction. Overall, the S1 Lite struck a sweet spot between convenience and performance. It reduced our manual prep time significantly, though we’d recommend it for light-duty maintenance rather than heavy-duty cleaning. Its balance of features and ease of use made it a solid addition to our spa care routine.
