Question: My unit stopped working after the first refill of reservoir. Now, water just dribbles out. Any suggestions?
Document: The water reservior last long than I expected, about 20 minutes under constant use. It is easy to remove and refill and cleaning of the Jumbl is fairly strait forward (a tool is included). The instructions are rather cursory, but most of the usage is self-eplanitory. I recommend using distilled water in this unit. Ditch your chemcial cleaners and try the Jumbl out!I have only three niggles regarding this product. One is that I wish it were cordless. I find the corded format limiting.
Great steamer. Easy to use. Reservoir holds decent amount of water for extended use.Wish it came with an extra scrub head.
It is easy to refill with water. It uses quite a lot and has to be refilled often, but that's ok with me as long as it does the job. It's lightweight and easy to use.I wish the cord was longer, but an extension cord will solve that problem.IF this doesn't fall apart, which I feel it will, I will be happy with it.Why can't we make anything in the U.S. anymore?
I could be wrong, but I suspect that it may not hold up that well over time. The reservoir is well designed, and the seals generally work well, but water does sometimes leak out, when you tilt the cleaner over.
JUMBL gives us a multipurpose steam cleaner. It may be small and very easy to put together and operate, but the number of tasks it can do well is probably endless.First, the power:  this steamer emits 1550 watts of powered steam and can operate on one filling with distilled water for about a half hour.
I have yet to use all the attachments but so far so good.Light ,easy to use ,noisy but easy to refill  removable water tank.Lasts 6-10 minutes on filling,handle stays cool. Cord long enough .So far so good.This is made to use distilled water but I am using tap water and will clean the nozzle as needed.Cleaning agents can be used brushed in and steamed off.Not bad for the price.
You needed to use a measuring cup to add the right amount of water, and once plugged in it ran until empty- at which point (the manual warned) you'd better turn it off before it self-destructs. The Jumbl has a detachable water reservoir- a very handy feature- and a pump that delivers water when you pull the trigger- also nice.
This steam cleaner is very lightweight and the water reservoir is easy to attach and remove, no strength is required, making it easy for elderly or unstable hands to use. Being light and relatively small, it easily fits into a corner of a suitcase, making it available for light touch up work on clothing that has been slightly wrinkled from being packed into a suitcase.
I tried the steamer about a week after receiving it, and was hoping it would remove some wax build up on my wood floor. I pointed it at the floor and it steamed for a a minute, but it was not powerful enough. I put on the brush attachement to steam  a stain on my couch, and it made a popping noise and will no longer work. All the unit does now is leak water all over the place and make noise...... do not buy!
Prior to being provided an opportunity to evaluate the Jumbl Steam Cleaner, I had given absolutely no thought to steam cleaning, or how a product like this might be used. Having used the cleaner for a little while, I find that it is a tool that could be used in a wide variety of cleaning applications.Operating the cleaner is fairly simple. You fill the reservoir with water, plug the device in, turn on the power switch, and within a few seconds, you should have steam shooting out.
Answer: Your heater is broken.  This happened to me as well.  I've gone through a lot of steam cleaners, but this had the shortest life span.
