Wat vacuum would be recommended?

Bissell makes decent vacuums that are inexpensive. I'm not sure what you mean by "low suction pressure", but if you need something that is more gentle, then choose a vacuum that has a "suction control" on it, which will reduce the suction power of the vacuum wand. If you need a gentle floor vacuum, then choose one with the ability to turn off the brush roll OR use a floor brush attachment on the wand.
