Perhaps a larger vacuum would have improved performance. While this device trapped most of the dust it collected, it did not collect it fast enough to be worthwhile for me. This item is more suited to a smaller project. The 10 foot hose was limiting. The sander easily took up strips of paper off the wall with out to much effort. I would recommend using damp drywall sander/sponges with beveled sides (for the inside corners). This items are even better used dry.
You get great suction and it sucks up over 90% of the compound dust. The dust would get everywhere and it just seemed to take forever. Before I bought this item sanding joint compound was the worst job in the world. It's loud as heck, but it works great. I never wanted to reapply compound b/c I knew I'd just have to sand it again and have another huge mess on my hands.well not anymore. This vacuum sander is the best. Now I'm able to get better results b/c I know I won't have as big a mess on my hands from sanding. This kit is pretty cheap and it pays for itself in no time at all.
I seldom clean the tubing set, except near the ends and the objectionable noise level is always near zero. The corrugations, however, exacerbate the tendency of the hose to vibrate violently (radially), producing the loud shrill.
After sanding without any type of suction device, I decided to try the unit again, one more time - I'm glad I did. When I first tried the Sand & Kleen, I was blown away by the noise (as other reviewers have commented on) and I quickly shelved it.
The corrugated tubing used for connection is an inexpensive solution to providing durability and flexibility for the interconnect. Initially, the unit screamed like a "banshee." I suffer from tinnutus and the high level of noise that was generated really caused me problems.
After a little use, though, the noise diminishes drastically if not completely.My theory as to why the change. After a little usage though, the dust from sanding coats the inside of the tubing and tends to "dampen" the vibrations (actually adds mass and dampening) and also helps smooth the otherwise corrugated tubing surface, thus attenuating the objectionable sounds.
After using it this long, so effectively, I can't imagine not using it for my drywall finishing projects - just be patient regarding the noise and I think you'll also be as pleased.
I have had once or twice the whistling sound, but it was not a big deal, a little noise or 95% less dust, it is a no brainer to me. I have been restoring my 1890's house and have used this extensively for the plaster resotoration I am doing. I hook it up to my Fein Vacuum and probably get 95% of all dust. I have been using this for 8 years with no problems, I am always amazed by the amount of mud I get when I dump the water out. It is the best 30 bucks you will spend.
This thing works as advertised. Wear ear plugs. I just had some clients call me a couple of days after a wall replacement and ask how I kept their house so dust free after 3 sandings. If you hang for than 6 sheets of drywall go with the one that has the 5 gal bucket. They were impressed.The only negative I can think of is the sanding handle isn't the most comfortable ergonomically. This bucket (about 1 gal) fills up with dust pretty quickly on big jobs and you find yourself emptying it alot. The 800 J is great for small projects. Its a cheap price to pay for a dustless job.
I took mine apart and replaced the original bucket with a 5 gal bucket. Between the shop vac and the whistling noise the Magna Sand makes, it is a loud process. I showed them the Magna Sand. Its tolerable though.
