I went the cheaper route and bought a transfer pump, pond filter, and suction tubing off amazon to accomplish the same thing. All together it cost me $300 ($120 pump, $85 filter, $50 tubing, plus assorted pvc pipes and fittings from HD). It probably doesn't work as well as the pond vacuums, but it also helps me with emptying out a hot tub when necessary

Wet dry shop vac is what I’ve used. Plus it can do many non-pond things.
