Home Depot currently has the Milwaukee M18 2 gallon wet/dry vac for $99. It can do wet and dry simultaneously, so it’s perfect for the boat or pontoon. It also has a blower port for inflating toys or for speeding up the drying process on wet stuff. The hose and attachments are self-contained, so it is extremely portable and easy to store. Way better than running extension cords and carrying a full size shop vac. No battery included at this price, so it’s really a good deal for those who are already invested in M18 tools or those who are starting a collection.
Posting links here is sketchy, so I’ll just say go to the Home Depot website and search for Milwaukee wet/dry vac or tool # 0880-20.
