Verdict

The Tristar SZ-1920 is a compact, corded bagged cylinder vacuum cleaner operating on a 230V power source with a 700W motor that generates 197W of suction power. Key technical specifications include a 2-litre dust bag capacity, an 8-metre operating radius facilitated by a 5-metre power cord with automatic rewind, and a 77-cm stainless steel telescopic tube paired with a high-efficiency universal brush. Main pros highlight its Energy Class A efficiency rating, a lightweight frame of 4.1 kg that ensures easy portability, and Class A performance capabilities on hard floors. Conversely, prominent cons include a high 80 dB noise level, a lower Class E performance rating on carpets, and an uncertified HEPA filtration system resulting in a Class D dust emission rating.
