Verdict

The ROIDMI S1 is a lightweight cordless stick vacuum cleaner featuring a 415W brushless digital motor that operates at 100,000 RPM to deliver up to 120 Air Watts (20,000 Pa) of suction power. Weighing just 1.5 kg as a handheld units and 2.6 kg fully assembled, it offers an ergonomic 270° handle, a multi-level HEPA filtration system, an auto-sensing LED headlight for dark areas, and a 2200 mAh lithium battery providing a 50-minute runtime in standard mode and 10 minutes in turbo mode with a 2.5-hour charge time. Main pros include its highly portable design, effortless maneuverability, high-end suction, and a convenient magnetic wall-charging dock; however, its performance is limited by a small 0.4-litre dustbin capacity that requires frequent emptying, a significantly shortened battery life when running on maximum power, and a lack of a user-replaceable battery design.

What customers like about ROIDMI S1?

  • Impressively lightweight main unit (only 1.5 kg) making it easy to operate with one hand and ideal for floor-to-ceiling cleaning.
  • Comfortable, ergonomic 270-degree handle design that minimizes wrist fatigue.
  • Excellent maneuverability provided by a flexible brush head that rotates easily around obstacles and tight corners.
  • Strong suction power on standard mode that effectively cleans hard floors, low-pile rugs, dust mites, and crumbs.
  • Innovative anti-tangle brush roller design that effectively prevents long hair from wrapping around the head.
  • Efficient multi-level/triple filtration system with a HEPA filter that traps fine dust and allergens.
  • Convenient, space-saving magnetic wall mount that simplifies storage and access.
  • Low operational noise levels in standard/eco mode, making it quiet enough to use without disrupting the household.
  • Modern, sleek, and aesthetically pleasing design compared to traditional plug-in vacuums.

What customers dislike about ROIDMI S1?

  • Very short battery life on high-power/turbo mode, yielding only about 8 to 10 minutes of run time.
  • Small dust bin capacity (0.4 liters) requiring frequent emptying, sometimes during a single cleaning session.
  • Emptying the dust bin can be cumbersome, requiring users to dismantle parts of the filter and cyclone system.
  • Inadequate suction power on high-pile or deep carpets, sometimes causing the brush head to stall or struggle.
  • Mixed feedback regarding long-term reliability, with some users reporting abrupt shutdowns or battery performance degradation over time.
  • Unreliable or glitchy smart app connectivity via Bluetooth for tracking battery and bin statistics.
