I just bought the PWD 30 C1 version for 75 euros, which is the exact same model as the B1, having the same functions, accessories and everything. I'll connect my Parkside sander to the PWD 30 C1 and use it to collect the saw dust (remove the filter from the sander and connect the vacuum cleaner's 1 meter hose to it, also plug the sander into the power socket on the PWD 30 C1). Thank you for the video, 16 minutes of useful information.
The people who make the wet and dry need to put a link for this video into the booklet that comes with the cleaner unit. Mine is really confusing and hard to follow. This guy is the video answer to wet and dry for dummies, he explains everything you need to know in simple terms, with video instructions.
Would you tell me please - When you've tested it with water what filter have you used? Nothing special is visible in the video. I guess you've just removed the paper filter and used HEPA filter only, am I right? When I've tested mine pwd 30 b1 with some water it started to spray water from the air output. The container is almost empty, so the reason is not a full container etc. I've checked 3 times - the HEPA filter is correctly placed so it's not the reason. Maybe my HEPA filter is pierced or you've used something else that is not visible in the video?
A comparison with the 20V one would be nice. The corded one it supposed to have 4x suction power than the cordless one (260 vs 60 airwatts) but I find that hard to believe.
