Disadvantages:

• Expensive
  Robot vacuums can be expensive. It’s an additional cost since you’ll still need a larger, more powerful one for deeper cleaning, stairs, upholstery, pillows, vehicles, elevated surfaces, and thick rugs.
• High Dust re-emission
  Recirculate fine harmful allergens and dust back into the air.
• Inefficient Cleaning Poor Suction
  Poor suction power and can’t reach the nooks and corners of your home where most of the dust and dirt is accumulated.
• Short Battery Life
  Most robotic vacuum cleaners come with a limited battery life, are expensive and must be replaced regularly.
• Noisy
  Unlike central vacuum cleaners that are mounted in the garage robot vacuum cleaners operate inside the house. There is nothing more irritating than the loud noise of a vacuum cleaner inside a house.
