My team and I love the versatility of the Pac Vacs. Some prefer the backpac, others prefer the barrel. I love them simoly because of their longevity and ability to last when other vacs cant. I was so annoyed at spending for vac's that only lasted for about 3 to 4 months. With the pac vac I know they are made to last. I also like the fact that some come with an extra extension cord and also are Tagged and Tested. Im slowly getting my whole team a pac vac but with 12 clients it is quite an expensive outlay. I I have also found that delivery is very quick wwhich means less downtime for my team.
