Vacuum Cleaners
Henry
Red tub vacuum, usually lives in the workshop area.
Good suction,easy to empty and clean, useful for clearing general workshop waste (e.g. saw chippings and dust). Has a particularly long cable on a built-in reel, so is the best choice for a quick once-'round-the-workshop clean up.
Kerstar
Blus tub vacuum, usually lives somewhere near the dusty area.
Large capacity and good suction, but this drops off when the tub becomes over full. Not quite as easy as Henry to clean out - there is a filter sock over a frame which needs to be fitted carefully to prevent dust passing straight through the motor.
OrangeVAX
Another tub, this one dedicated (at present) to the bench-top bandsaw.
Dyson Upright
Purple beast lives in the blue room as that is where ther is the most carpet needing cleaning.
Others
Small cylinder-type bagless vacuums of varying quality are attached to some tools. These all need to be checked regularly to make sure they don't become too full.
