Bladeless fan move lesser air and more noisy to operate, you may also feel it is not strong enough if compared with conventional table fan.

Maintenance wise, as long it doesn't have good filter, the blade inside & parts will accumulate dust just like Aircond blower and even harder to take apart to clean.

Those with good filter like Dyson help u clean the air and which reduces accumulation of dust on the blade with at a price of the Fan itself + the filter maintenance/change.
