Based on ratings from across the web.
Reviews last updated: July 2026 · How we calculate this

What customers like about Aigostar Keith

  • Extremely lightweight design under 500 grams makes it very easy to maneuver and comfortable to hold for extended periods
  • Conveniently charges via a USB Type-C port, allowing flexible charging options from laptops, phone chargers, or car sockets
  • Equipped with a three-level dual filter system including a washable HEPA filter that effectively captures tiny dust particles
  • Compact and highly portable, making it ideal for quick cleanups in hard-to-reach spaces, office desks, and vehicle interiors
  • Operates at a relatively low noise level under 70 decibels, providing a comfortable cleaning experience
  • Comes with a versatile 2-in-1 crevice nozzle and brush tool suitable for keyboards, food crumbs, and pet hair

What customers don't like about Aigostar Keith

  • Limited continuous battery runtime of approximately 20 minutes on a full 3 to 4-hour charge
  • Suction power of 4.5 kPa is primarily suited for light debris and minor messes rather than deep or heavy-duty cleaning
  • Very small dust container capacity of only 100 ml requires frequent emptying during usage
  • Power button requires holding down for 3 seconds to activate, which some users find counterintuitive
  • Not suitable for vacuuming up wet spills, liquids, or large obstacles

Verdict

The Aigostar Keith is a compact, cordless handheld vacuum cleaner powered by a 50W, 7.4V motor that generates a strong 4,500 Pa suction pressure for quick daily cleaning tasks. Weighing just 480 grams, it features a 2,200 mAh lithium-ion battery providing up to 20 minutes of runtime, a washable three-stage HEPA filtration system that captures 99.98% of microscopic particles, a small 100 ml dust tank, and convenient USB-C fast charging that fills the battery in 3 to 4 hours. Main pros include its highly portable, ultra-lightweight ergonomic design, operational low-noise levels under 70 dB, and a versatile 2-in-1 crevice brush attachment ideal for cars, keyboards, or small home messes. However, notable cons include its minimal 100 ml tank capacity requiring frequent emptying, a relatively short 20-minute battery life that limits extended cleaning sessions, and a specialized 3-second long-press requirement to turn the device on.
