Haven't had my swiffer long. It quit spraying and changed battery's it work the rest of that day. Pulled it out again and won't spray again. Changed battery's again Still won't spray. What is wrong?

How long have you owned the machine? Do you still have three year warranty? I wouldn't recommend spraying anything into machine. It will only damage the electronics. It may need to be fixed. Does the remote control still work?

By changing the Collector Cell. The flashing light is an indication that it needs cleaning.
Here is a link to model you listed above. It has all the information you need, on how to clean the Collector Cell. You can download and print it for future reference.

Hope this helps you solve the problem.

When was the last time the backup battery was checked? The trouble indicator could mean a weak or non-working battery. If the system is 12 years old, the battery should be changed.

Mine quit too... The led screen went blank so I changed the battery. Now it does nothing. I totally disassembled it as the fan was turning stiffly.(should spin very easilly) The grease in the end bearing was stiff. I washed the gummy grease off the shaft and reoiled with synthetic oil. Your smell is probably motor windings overheating. I disassembled the electronic control and was disgusted to see that there is a glass fuse soldered to the circuit board. I believe the only reason for this fuse is to cause us consumers to needlessly replace otherwise good equipment. (It cost more to pay a repairman to replace the hidden fuse than to purchase a new unit)The fuse is not blown. At least this fuse actually looks lide a fuse unlife the stealth fuses most electronics have hidden in them. I can not obtain a wireing diagram on my 17005 unit but it has a black box inside behind the control panel. It looks like a small start capacitor, but it has a temp rating on it of 70*C. I suspicion it is a single use over heat safety which triggered when my motor got hot due to stiff bearings. I refuse to play their game and purchase a new air cleaner. I love this one... So, if I can not determine what that little black box is, I am going to bypass all the crappy electronics and just drill a hole on top by the handle and install a hi/lo/off manual switch directly to the motors wire hasness. This machine will never give me problems ever again, and if I oil the motor every couple of years with synthetic (Ander oil) this unit WILL last me for the rest of my life...

electronic circuit needs repair

When you add water, you should notice bubbles (just a few) on top of the water.  When the water no longer has bubbles, the additive is shot, and you should wash out the tank.  We have dirty air, and it takes about 2 weeks for us.  I spray it with Murphy's Soap to soak a few minutes and wipe it out with a sponge.  Rinse.   Spray the wheel similarly (all over) and spray with a kitchen hose, as hot as possible.  You may have to repeat.  I clean my wheel between tank cleaning, so it doesn't build up.  You should use the additive, because the water has to be slippery to work with the wheel.  Maybe you can find a different "wetting solution,"  that would be cheaper;  Venta gets an arm and a leg for it.  Good Luck.  I like the performance of mine, but it is temperamental.

If you haven't done so, try replacing the lamp starter.

you have to plug the unit into the wall directly and not to a power strip or UPS. Then just choose the speed for continuous filtering.
