I am very pleased with the purchase, and given that before this assistant I had a heavy vacuum cleaner with a wire and an uncomfortable hose, then I am generally beside myself with happiness! It is not very heavy, cleaning a 60-meter apartment takes 15 minutes, during these 15 minutes the battery is discharged by only one division. It is not a problem to clean the tank and filter every time, the design is easy to use. Lighting is a brilliant invention! Now I do not burn the light in the whole apartment during cleaning.
