Variable Speed Control
Your review: The vacuum works as expected. My one complaint is that while every other part of the vacuum is in the box the HEPA filter attachment is stored in the very bottom of the vacuum. As there was nothing in the box to indicate this it took several communications with Global Industrial to figure out why the variable speed control instructions showed a different top to the vacuum I had received...
Pros: - suction control - multiple attachments
Cons: - variable speed control attachment seems like an afterthought rather than a design feature
