Champagne gold robot vacuum cleaner equipped with a HEPA filter. Easy operation with touch buttons. - Brand: HITACHI - Model: RV-EX1 - Filter: HEPA filter equipped - Color: Champagne Gold - Operation buttons: Touch buttons Thank you for viewing. Although it was manufactured in 2018, I purchased it in 2020. I used it for about 3 years, but haven't used it for the last 2 years. I confirmed it for the listing, and it works without any problems. I have handled it with care, but there is a feeling of use. I think there is a performance difference compared to current robot vacuum cleaners, and I had trouble with dog hair getting tangled. Please understand this before purchasing. I will include a new rotating brush, cleaning brushes for the dust box, etc., a remote control (never used), a charging stand, an instruction manual, and an easy-to-use guide booklet.
