Is 15,000 Pa enough for car seats and floor mats?

Yes for loose dirt, crumbs, sand and pet hair on fabric. It struggles with embedded grit in deep carpet, so use the crevice tool and go over mats twice.

How long does the battery last per charge?

The listing gives no run time. At this weight and battery size, expect roughly 10 to 20 minutes on low and under 10 minutes at full 15,000 Pa. Charging takes about 3 hours over USB-C.

What can the blowing and inflation modes do?

It inflates air mattresses, pool floats and tires with the right nozzle, and the blow mode clears dust from vents and keyboards. Vacuum compression helps shrink storage bags.

How often do I empty and clean it?

The 120 ml cup fills quickly, so empty it after each car session. Rinse the HEPA filter every few weeks and let it dry fully before refitting, or suction drops.

How does it compare with a Shark or Black+Decker handheld?

It is lighter and adds inflation and blowing, but those brands offer larger bins and longer run times. Pick the Neverland for portability and multi-use; pick the others for longer cleaning sessions.
