The La Sonic Supreme Jewlery Cleaning machine by Connoisseurs has two tanks, one for cleaning and one for rinsing. These tanks receive sonic waves independently creating more cleaning power for cleaning and rinsing in each tank. As important, these two tanks are completely removable so that you can empty and clean each tank with ease and without mess after each use. The LaSonic has some other attractive conveniences. It has a lid storage compartment that lets you store a lint-free drying cloth (included) or a polishing cloth. The LaSonic also has a space saving cord storage feature that lets you wrap the cord conveniently underneath the machine when you are not using it. The LaSonic is powered from a standard 110 volt electrical outlet. Each machine comes with a starter packet of cleaning solution, a lint-free drying cloth, an instruction booklet complete with a jewelry care guide and a 2 year warranty.
