Keeping the filter clean
A wet and dry vacuum connected to a power tool is a dust extractor, and the connection is where it usually fails. We cover hose diameters and what each suits, antistatic hoses that stop the shock you get from sanding, tool adapters, and cyclone separators — which keep the bulk of the debris out of the filter entirely.
Drops the bulk of the debris into a bucket before it ever reaches the filter.
A cyclone without a tank — you supply the bucket, and it costs a fraction of a complete unit.
The cheap plastic part that decides whether your vacuum can be connected to your sander at all.
A hose's two ends have two diameters, and most of the time only one of them lands right. The stated diameters at both ends are this aisle's first sort.

Moving the drum every metre is what puts people off extracting at source. The stated length says whether the machine stays put for the whole session.

It is set by your vacuum's outlet. The common values are 32 and 35 millimetres; adapters let you step down for fine work.
It drops most of the debris into an intermediate drum before the filter. The filter stays clean far longer and suction no longer collapses mid-session.
Yes, noticeably. The loss is proportional to the length and increases sharply if the diameter is reduced over part of the run.
No. Every tool maker has its own outlet, and adapter sets exist for exactly that. An approximate connection lets the finest dust escape.
With a large diameter, yes. On a narrow hose, planer shavings form a blockage almost immediately, often in a bend.
On dry wood and in dry weather, static build-up is real and unpleasant. It is not dangerous to the vacuum, only to the user.
By detaching and shaking it, or by reversing the connection for a few seconds if the machine allows. Pushing a rigid rod through it pierces the sleeve.
It passes more air and more chips, but the air speed drops and fine dust settles inside the hose. Thirty-two millimetres for fine work, thirty-eight and up for chips: that is this aisle's trade-off.
The hose and the connector decide what the vacuum actually captures at source, and a cyclone separator does more for constant suction than any amount of extra power. Diameter is chosen on what you pick up, not on what fits.
A figure has to be published by four machines in five to earn its column. Below that, we would be comparing empty cells.
