The robot vacuum was the first smart home gadget to revolutionize the cleaning world, but a lot has changed since this invention debuted in 1996. Here are a few gadgets to add to your home to help you clean smarter, not harder.

• Robotic mop and floor sweeps are sure to change the way you handle everyday spills. Some robot vacuums have built-in mops and floor sweeps but expect to pay more for those models.

• Say goodbye to fingerprints with a robotic window cleaner. They're good for indoor and outdoor use and have built-in mechanisms to keep from falling.

• Life as a cat owner will never be the same after you get a self-cleaning litter box.
  You can even buy a self-cleaning “dog potty” for dogs under 25 lbs.

• Have fun watching your barbeque grill scrubbing robot do all the work as you get ready for your next cookout.

• Breathe easier with an air purifier with a high-efficiency particulate air (HEPA) filter. Air purifiers can improve indoor air quality, providing relief for those with allergies.
