DeWALT 1300W Wet Dry Vacuum Cleaner - 45L Tough-Built Vac for Carpets, Couches, Hard Floors and Patios - Garage Blower with Drain Plug and Accessories, Ideal for Carpet Cleaning and Outdoor Use.
Basically a really nice and powerful vacuum cleaner. I got one to serve as a shop vac but there are obviously multiple uses for it with it being a wet/dry unit. You can also add a HEPA filter to it if you need to.
This unit comes with glowing reviews and this is the cheapest I've seen in a long time. I probably don't even need a 45L unit but for some reason it is cheaper than some of the smaller models at the moment.
Also, this is a corded unit in case you're wondering. Plug it to your electrical socket and go, no batteries required.
I'm in the market for a cheap Wet/dry vac, but waiting for a good deal on one with Power Take Off.
