What customers like about SUITU ‎ST-6645C

  • Lightweight and compact cordless design is easy to handle
  • Useful dual-purpose vacuum and blower functionality
  • Comes with a good selection of accessories for narrow gaps and mixed surfaces
  • Charges conveniently through a standard USB cable
  • Good for quick cleanups of crumbs, desks, and small areas inside a car
  • Washable HEPA filter keeps maintenance simple

What customers don't like about SUITU ‎ST-6645C

  • Suction is too weak for deeply embedded dirt in carpets or upholstery
  • The filter clogs quickly with fine dust and needs frequent cleaning
  • Battery life is limited when used continuously at full power
  • The included brush can feel too small and too weak for stubborn pet hair
  • Some users report random cut-offs if the unit overheats

Verdict

The SUITU ST-6645C is a portable, cordless handheld vacuum cleaner constructed from ABS material, operating at a rated voltage of DC 7.4V and generating up to 120W of power. It delivers a strong suction capability of approximately 9000Pa paired with a rated motor speed of 35,500 rpm, and it features a 0.2L dust cup capacity alongside a washable HEPA filter system. Its main advantages include ultra-lightweight portability at roughly 500-525g, 5V USB boost charging that powers its dual 2000mAh lithium batteries for 20 to 30 minutes of continuous runtime, and versatile multi-functional suction or blow nozzles suited for both home and car interiors. However, noted drawbacks include a relatively high operational noise level reaching up to 84dB, a small dust capacity that requires frequent emptying, and a tendency for fine debris to clog the filter quickly.
