A: As long as it is sealed hardwood, then yes.

A: Yes, the Steam Dynamo can clean carpets. It comes with a floor head cleaner attachment.

A: Hello! The Steam Dynamo emits steam for cleaning surfaces. If you are looking for a machine that can clean hard floors and vacuums both carpets and hard floors, the EPV1100 is the tool you need. It has 4 functions: polishing, scrubbing, cleaning, and vacuuming.

A: Yes!

A: Thank you for your question. Anytime when you are dealing with electricity you need to be careful. Never submerge an appliance into water that has a cord. And be careful of the cord itself, making sure there are no holes or cuts in the cord before plugging it is. Also never touch the metal prongs while plugging in the unit. The steam cleaner has a canister that is molded on the inside so the cord itself is sectioned off and protected from the water used in the unit. Also be sure to follow the directions and safety instructions provided in the manual before using the unit, and if there are any other questions you may have please call the manufacturer for additional information.

A: Thank you for your question! The steam cleaner specs allow for 50 mL of water in the tank, so the distance it can go is determined by that vs the size of the room or stairs. But yes! It is great for all upholstery and carpeting including any hard floors or surfaces.

A: Yes. We always recommend you try it on an inconspicuous area to confirm you are getting the results you expect. Confirming recommended use would depend on the couch material for us to give a more definitive answer.

A: Thank you for your question. Yes this unit can be used to clean any upholstery as long as it isn't a delicate material like satin, silk or leather. It's great for upholstery in your residential home or personal car. The long floor brush is the best accessory for this.

A: Thank you for your question. No, cleaning solutions can not be added to the water in the tank. This is render the product and warranty useless. The best practice for the steam cleaner is to use distilled water to limit build up, and to run a vinegar solution through it occasionally to keep it clean and increase its longevity.

A: Thank you for your question. The Cord is 8 feet long. In the manual it states: It is recommended that a suitably rated GFCI/ALCI device is fitted into the mains supply socket for added protection. If you use a power strip or extension cord please make sure that it has a surge protector. Thanks again for your question.
