My Henry vacuum has packed in. It don't like concrete dusk. Wasn't powerful enough. Looked at something else. Price range £100-£200 Want it to Hoover the floor and dust extractor too What do you have?
If u want one that does concrete dust don't get a nikfisk, my workmates one clogs up all the time doing concrete dust etc
If your henry is under 2 years old , then take it back they give you 2 years guarantee Im on my third replacement now
I have a Nilfisk with power adapter thingy on it, never had a problem with conc dust as use a pre filter on it
Hilti vcd50 is designed for the job but costs loads. I've got the same as coolio but use a preseperator to collect most of the dust. Were you grinding down some conc by any chance? Doing that killed my Henry and my nilfisk. That's when I went to the current set up
