Where do the batteries go in my swiffer wet jet?

At a guess, there was an error made in assembling it. Take it apart and follow the directions again. Are the batteries in the correct way? Are they good?
Without more detail we don't know why it doesn't work

Refill service for the Duster, PATHETIC!!! This shouldn't be so hard to find the slots to put a new duster on the wand. NOT WORTH the Money!!! Shame on me for giving you my hard earned monies, for a ** product.
I agree with a lot of what some people are saying except the person who said they don't make the xlarge wet cleaning size sheets. Yes, found them at Lowe's. Expensive but good idea about individually wrapping them. Kudos to the person who thought of that. I give you 4 stars but please make sides a tad longer for more tucking in tabs. You do that and I will give you 5 stars. Also make them easier to find.
Loved the fact that it was a quick and easy in between regular mopping with a mop and bucket. After using it for about a year I noticed that my kitchen floor was looking dingy and tacky (even though I used a regular mop with hot soapy water at minimum of 3 times a month). I ended up on my hands and knees scrubbing with a scrub brush with dish soap and bleach... the dirt that came up was unbelievable! I won't use the WetJet anymore. I always loved the regular dry Swiffer for hardwood floor and still recommend that for a quick dusting or removal of pet hair, (not crazy about the wet pads though). The solution from the WetJet is totally the issue... It leaves a film that attracts dirt and holds it in the grooves of the flooring. I wish I had invested in floor steamer as I probably spend the $100 on the WetJet, pads and solution I have used in a year.

Pull up on it.

Hello, Ellen -

If you Google any chemical and the acronym "MSDS" you will find all the information manufacturers have to provide the public for handling and transportation.
As a chemical cleaner, it is pretty mild but dont use it to wash out your kid's mouth if he swears....or your dog mouth either.

Just under the bottle, where you see the letters CE, there is a green tab.
Push it down, and the cover comes out.
There will be 4 AA batteries inside.

Be sure to put them in with the correct polarity. It is marked in the diagram inside the door to the battery case.

Check the battery output, or take your jet to someone to open it for you to check the connections on the battery slot.

Keep your dog clean, make sure you have it shampooed and you should brush your dog daily. You don't need extra water, just use Swiffer, both wet and dry, and your floors should be clean.
