A great powerful helper for every household

His performance is absolutely perfect. Even better washing is ensured by the functions of the double cleaning cycle. The ultrasonic water spray creates a 15 micrometer thick mist that dissolves dirt and then polishes the glass perfectly thanks to special wipes. In the event of a power failure, the Hobota 388' s backup UPS battery protects the work, and a five-meter rope protects against falling.
