yes i bought one .they are ok ,but i have nothing to compare it with
.i have used it on 4 jobs now .the highest was 3 floors.not sure the camera will last that long .can see it getting knocked.and the vac is limited on scrapper tools and prods to loosen up the debri.
but it did the job .the kit cost me 900 and i have made my money back.my advise would be to buy the vac with a fellow wc as you wont be useing it that often ,but it is good as an add on to your existing jobs.
also there is a seyt up time ,so make sure you price jobs accordingly.
