Magna MT800 Sand & Kleen Hand Sander System

Comment: I was impressed by how well this worked. I have done many a DIY drywall project, I hate sanding, hate it. I don't do it enough to get really smooth joints w/o some sanding. This really did capture most of the dust and my shop vac filter did not need cleaning after completing a 10 x 12 room. I did have to clean the hose and sanding attachment 1/2 way through the job. I wish the connection on the lid was more robust it came loose and it took me 10 minutes to get the compression ring back in place. It is very LOUD, but I wore ear protection and was fine.

Comment: Unit arrived with missing adapters. Unit was not assembled, had to figure out / attach hoses to lid. God-awful whistling as others mention. Unbelievable junk for $50. The idea is sound but was probably engineered by the salespeople who hold a patent on similar vacuum cleaner (rexair? rainbow?), effectively creating a monopoly, preventing competition, charging rich customers $3000. Just get yourself a good shop vac (which you can use for other things) and spend $5-$10 for a fine dust bag insert (my Ridgid 16-gal works fine). Also read instructions on your mud: it can often be done with a sponge to avoid dust. Amazon could drop this product imo. I may buy a decent hose and reengineer the lid in future if need arises again. Sorry, I can't sell the redesign. ;-)

Comment: It is the first time I have owned one of these units myself. I have seen this type of collection system used before. This unit is not for pros. The hoses are far too small in diameter and can't collect enough air (and dust) to keep a dust free room for a fast sanding drywall pro. It only collected about 70 percent (at most) of the dust when I was sanding. To get a dust free room sand very, very, very slowly so not to disturb the small amount of suction at the sanding tool (again the hose is too small). Of course I read the instructions and closed all the bleed off valves to get maximum suction. Compared to the home made or home made looking units the pros use with the large diameter hoses this thing is kind of sick. Would work great for a very small area where you can sand slowly but when time is money look to a different unit.

Comment: This tool does reduce the amount of sanding dust. However, the lid is too flimsey and my vacuum litterally sucked it into the bucket. I had the air bleed almost all of the way open to reduce the pull of the lid but even the lid on a bucket of drywall compound or kitty litter is heavier than this weak thing. If your building a product used by the construction trades then make it out of construction grade materials and not the cheapest bucket you can find. I will convert an empty 5 gallon paint bucket to replace this one.

Comment: After sanding half a room and getting dust everwhere throughout the house I bought the MT800 system. It worked exactly as advertised although if you had several rooms or a tight deadline you might consider some help. I give this a big 2 thumbs up.
