"The specs are a work of fiction, but the price is very real."
The 45,000Pa suction claim is almost certainly fabricated or measured in a lab under conditions that have no bearing on reality; expect suction comparable to other budget vacuums, not flagship models it claims to surpass.
This is for the buyer on an absolute minimum budget for a small space, who needs a vacuum for light duty on hard floors. It's a gamble on a feature list, where the low purchase price is considered the primary feature.
Anyone cleaning more than a small apartment or who has medium-pile carpet should skip this. If you expect a product to last several years, have accessible customer support, or perform as advertised, look elsewhere.
