After the final visual count, the cages were carefully emptied with a blower-vac to obtain near-total numbers of arthropods (fig. 2).
The total number of arthropods collected with the blower-vac at the end of the experiment confirmed findings from visual observations.
There is therefore going to be a market for the first developer who can design the 'self-emptying' robot-vac.
I think it will be found on investigation that there are here chromium plated anti-vac traps which have been put in at cost-plus profit.
The first time one man went round the bits that were free with the vac.
Also, the pads/brushes, vac hose, and squeegee should also be rinsed to prevent dirt build up.
A source for vacuum in some applications may be as simple as a typical shop vac or vacuum cleaner, in light application.
Hi-vac mowers have a tunnel that extends from the side discharge to the bag.
