Mighty Pro X3 vs Deep Carpet Cleaner
images from manufacturer

If you are deciding between Rug Doctor Mighty Pro X3 and Deep Carpet Cleaner. I think the first thing you should take into consideration is the PRICE. These two rug doctor carpet washers are not at the same price level. On rugdoctor.com, the list price of the Mighty Pro X3 is $459.99 that is $200 more expensive than the Rug Doctor Deep Carpet Cleaner.

The other thing that matters is the Weight. For those who care about the product weight, just buy the Deep Carpet Cleaner. The Mighty Pro X3 is bulkier and much heavier, a little challenging to carry it up and down stairs, if you are not strong but decide to buy the Mighty Pro X3, please think twice. It is also more difficult to push around.

About the Tank Capacity. The Mighty Pro X3 has much larger clean water tank and collecting tank capacity. It is about 3X of the Deep Carpet Cleaner. On one hand, larger tanks means less refilling and emptying. But on the other hand, the larger waste tank that has a capacity of 3.9 gallons gets quite heavy when full, heavier to lift to dump.

Though the Mighty Pro X3 is bulkier, one thing that is strange is that the Mighty Pro X3 has a narrower cleaning path, it is smaller than 11 inch versus 12 inch on the Deep Carpet Cleaner.

Warranty. The Mighty Pro X3 is commercial grade, it carries 5 year limited warranty versus 2 year on the Deep Carpet Cleaner. Commonly, a longer warranty means that the machine will be longer lasting?

Side brush, not an important one. But if you like it, the Deep Carpet Cleaner has the edge brush while the Mighty Pro X3 does not feature.

Some similarities:
They both have separate clean tank and dirty tank, adjustable and collapsible handle.
No built-in water heater, so you use hot tap water.
No separate detergent tank, you have to pour detergent into hot tap water before cleaning.
No rinse only option. You should fill only hot tap water without any detergent to rinse your carpet.
Designed only for carpets, area rugs, upholstery, cannot be used to clean hard floors such as tile floor.
