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.
