I could not be happier with the strength of the vacuum. When I first used it I had a fight because it wanted to suck the floor off the ground, you will pick up the finest of dust particles (very healthy!) I tested on a 1x1 ft. area and you'd be astounded by how much dust was in the bag already. It will even pull things in from a couple inches away from the nozzle. Very lightweight and the heat blows out and away from your body which is great. You will have to get used to how to hold the hose as to not knock things over behind you, but once you get used to it you can still work in tight areas (it is difficult though.) The length of the cord is fantastic, you can vacuum an entire floor of a 3-5 bedroom house without reconnecting to another outlet. The length of the wands are great, you can at times stand in the middle of a room and vacuum the entire room.Here's my problem and it's a big one. For every attachment kit there is a separate wand you must use . . . For every wand there is a different hose. It's a terrible sales tactic that will prevent me from purchasing more from proteam. With the technology in 2018 it is inexcusable that the company makes you spend hundreds of extra dollars because they refuse to make attachments that are universal to the wands and hoses. For jobs that call for different attachments this is also a great concern because the time you save vacuuming with a great vacuum is almost lost entirely when you have to stop what you're doing and exchange the wands and hoses and attachments (some of the attachments dont even properly fit the wand they belong to) where even a $100 house hold vacuum is as simple as clicking a button to change attachments.Overall, if you don't have a diverse home or if you own a cleaning company and don't have a variety of different style buildings and layouts then it's truly amazing. As for those who need a wide variety of attachments it's not worth the money or time.
