While there are some special ‘wet and dry’ vacuum cleaners out there that can be used to suck up liquids, Dyson vacuums should not be used for this purpose. Dyson doesn’t make any wet and dry models, so no matter which vacuum you buy, you shouldn’t ever use it to try and suck up any spillages of water or other liquids. The main reason for not sucking up liquids into a Dyson is that they can interfere with the electronics and potentially damage or ruin the cleaner entirely. They can also put the user at risk of electrocution in some cases, so it’s definitely not safe, and the filter in your Dyson isn’t designed to handle liquids either.
