Dustless Technologies D1603 Wet+Dry Shop Vac – Powerful Dustless Vacuum for Contractors, Construction, Professional, and Home Use

Over the years, all other vacuums I've had, were more expensive, louder, had less suction and leaked drywall dust into the air as they aged. Over the past year that I've had this one, it has performed just as the description says and keeps the area cleaner than any of the others. I use the 3141 Wet/Dry Micro Pre-Filter Bag (Wunderbag). The vacuum never leaks dust into the room and the even the inside of the drum stays clean.The instruction manual is a bit vague on several points and leaves out others. By trial and error, I found that there is no need to use the external agitating rod to shake the small filter protecting the motor, IF you are using a large Wunderbag in the drum to catch all the drywall dust. (In that case, the motor-filter will never get any dust on it, anyway.)Additionally, to maintain maximum suction when using a large Wunderbag, I found that it's important to open the drum lid every couple of hours of usage and shake the two main legs of the large Wunderbag a bit, to knock the dust off and down inside of it and allow better air-flow again. (Be sure the hose is attached to the port when shaking it or you'll force dust out into the room.) Also when shaking it, you should hold the neck of the Wunderbag tightly against the cardboard collar at the inlet port, so that it doesn't tear away from it. If a gap opens up, dust will get into the inside of the drum and onto the motor-filter (but still not out into the room). A little superglue can fix the issue if it happens, but I wish they'd bond the bag to the cardboard collar better.The large Wunderbags are fairly heavy-duty, but the description warns against sucking up sharp stuff like wood chips, etc., that might puncture them. I've used (4) bags used over the past year and none have developed any holes (but I've only used this machine when sanding drywall, not general cleanup that might have damaging pieces of stuff getting sucked up.).

I gave away my vacmaster and shop-vac brand vacuums and am happy with this one. How do those things get high ratings???? Vacuum manufacturers always list air movement as a measurement of vac power, but we don’t care about that. We care about lifting solid stuff into the vacuum, That measurement is “vertical lift” and very few manufacturers post it because their machines are terrible. I found this vacuum after searching extensively for high vertical lift ratings.This isn’t a perfect vacuum, but it does what it is built to do very well, so it is great in my book. Things that could improve: The connections are a tension fit and always either stuck together (paint and drywall dust welds them together) and very difficult to separate (the hose is very big and hard to grip), or falling off (gritty dust creates scratches in the soft plastic connections and prevents a snug tension fit). The storage for the hose, cord and accessories, and the hand holds for steering and lifting are either puzzling or missing completely. Hopefully the company will improve the connections in the next design. That is the most important of these (hint).

My entire house was full of popcorn and thick wall texture. Popcorn removal and sanding skim is a drywall dust nightmare. Do I still have drywall dust, off course I do but hooking this up to the sanders made an impressive improvement for clean up! Contractors said it was the best they had ever used!

Only issue that I’m have is bag is quarter full of drywall dust, just went to open, full of dust. And 2 small holes on upper sides. Looks like it’s rubbing against something inside.

When my husband and carpenter heard how much I paid for a construction vacuum, their jaws hung open for five minutes. Well, they ended up fighting who would do cleanup with it by the end of the day. The extra $100 or $150 dollars was worth it the first time we used it. The special filter bags really keep everything inside the machine. Its suction power is amazing, and much stronger than any of my ShopVacs. I’m going to keep it in my art studio for cleanup because I can’t sweep anything due to resulting dust. I swear that you won’t be sorry. You have nothing to lose!

Great vacuum but hose is POS. The hose broke multiple times. Finally just replaced with a Rigid brand hose. Probably would not recommend this. Probably would be better using a regular shop vac with bags and an Oneida Dust Deputy.

This vacuum was amazing at first use! It filtered the sheetrock dust so well that when we lifted a full bag out of the canister, there was ZERO dust inside the canister! (vacuumed up a TON of sheetrock dust) So, so happy we did not purchase a traditional shop vac that would most definitely clog up. (and not clean as well) Well worth spending more money on this as you save time not having to vacuum twice. The suction is excellent. The weight is not too much. Great purchase! 5 stars. Recommend

I really like this vacuum it does a great job. I use the dustless bags and they're great. I put this unit through a lot of abuse in my concrete shop. It is wearing down in certain ways I'm on my second floor wand but those aren't too expensive (the wheels fall off). Overall this is a good machine.
