Review on Revolutionize Your Cleaning with Ultenic U11's Self-Standing Removable Filtration by Daniel Pyfer

Suction power is of course proportional to motor power. All battery powered vacuum cleaners, robotic or not, have 5 or 6 cell (19-22V) batteries, which limits the power they can deliver to the motor. Ultenik developed an 8-cell (29V) model and I had to have it. Let me tell you that it outperforms any cordless vacuum I've ever seen, including the overpriced Dyson which I unfortunately own. It approaches the performance level of a corded vacuum cleaner. As expected, power comes with weight, it's slightly heavier than the Dyson. The stand is great, I hate drilling into walls. The trigger is a bit annoying - there's a slight delay before the vacuum starts up. The trigger itself is a toggle switch, not a momentary Dyson switch. I'm still trying to understand mt feelings which one is better.
