Narwal Freo robot vacuum and mop combo: Save $500

This sleek robot vacuum/mop combo went viral on TikTok during Black Friday last year. It comes at a hefty price, but the robot is a smart cookie. It boasts DirtSense technology, which means that if the robot detects a dirty area, it'll go over that soiled spot multiple times until it senses that it is completely clean. 

It also adapts its cleaning to the floors as it moves, including making changes to the suction power, mop pressure and dampness of the microfiber clothes as it sees fit. 

The docking station is just as impressive. It washes the mop, dispenses the mopping solution and separates the dirty water, so all you do is lift the dirty water tank to clean it. You can control the robot vacuum/mop combo on the docking station's LCD screen or the corresponding app. 

You can get this $1,400 item for $900 with an instant coupon -- a savings of $500. 

iRobot Roomba Combo j5+: Save 44%

This iRobot cleaning combo machine is about half the price and offers many of the same features as its higher-priced counterparts. 

This includes object avoidance, a multi-stage cleaning system, home navigation, an app that can set up cleaning schedules and more. The only difference is that it doesn't vacuum and mop at the same time; you have to switch the bins to activate different cleaning systems. 

The iRobot Roomba Combo J5+ also has a self-emptying docking station that can hold up to 60 days' worth of dust and debris. 

Normally $800, you can get this for $449 on Amazon for a limited time. 

What is the best robot vacuum?

When searching for the best robot vacuum, focusing on a few important features can help. For starters, pay attention to suction power. Strong suction is important for digging up dirt, dust and pet hair from carpets and rugs as well as hard-to-reach areas. Battery life matters, too. Some vacuums run for more than two hours per charge, and they can return to their base and charge themselves up so you don't have to. 

You'll also want to consider navigation and mapping capabilities. Advanced systems like visual mapping let robovacs map rooms and avoid obstacles. Of course, convenient features like Wi-Fi and voice control through Alexa or Google Assistant make life easier for you. With an app, you can schedule, monitor and control cleaning remotely as well. Any time you can automate what a robot vacuum does is a bonus – leave all that hard work to the machines.

Look for large dustbins so you empty less often, especially with pets. And HEPA filters do wonders for capturing dust and allergens. Finally, match the vacuum's brushes to your floors. Specialized brushes are good for pet hair, for instance. You may need a vacuum that handles hardwood floors better, and you don't want to be stuck with one that can't handle the demands of your home's flooring.
