The Florio also excelled in our vacuuming performance tests. It navigated and cleaned our two-room obstacle course faster than almost any other model we’ve tested. On bare floors, it impressed us by lifting an average of 96% of debris.

The Roomba s9+ also comes with a self-emptying charging base; while it's unfortunate that you'll have to purchase replacement bags for this base, you will only have to empty the container every 30 days. This will save you a lot of time versus emptying the onboard dustbin.

Compared with brushless suction port, the roller brush can deep clean fine dust in all types of floors. Cleaning brush help to solve the entangle hair, no worry about it.

You can set them to clean just the kitchen floor after dinner or an entire level of your home while you’re out of the house. Can you get it done faster with your regular vacuum? Sure. But the real question is, do you want to?

Although the RS20 Pro did a decent job at maintenance cleaning, has plenty of settings, and a great app, it fell short on several other things. It couldn't cope well with heavy-duty messes, particularly when tested on cat litter.

There are a few caveats when purchasing a robot vacuum this cheap. For starters, the iLife V3s Pro is slow, taking more than 90 minutes on average to clean a 5x5-foot test space — others took less than 30 minutes.

Most robot vacuum models can easily handle cleaning both carpets and hardwood, but some are better at cleaning one or the other. Higher-end robot vacuums such as the Roomba J9+ Combo can accommodate rapid surface changes by folding its mop pad atop itself and ramping up power whenever carpet is detected, and then throttling back down when it senses hardwood.

Shark AI’s compact design and self-emptying bin make it a standout choice, especially for carpet cleaning (it's our best overall pick in our roundup of the best robot vacuums for carpet).

The handheld vacuum was a great complement; not only did it suck the crumbs out of our couch cushions, but it was also able to pick up the kitty litter that the Deebot T30s missed in the carpet cleaning lab test.

Robot vacuums usually don't require much upkeep, but each model will have its own maintenance requirements. There are things you can do to keep your robot working in tip-top shape like removing tangled hair from the Top 3 Automatic Vacuum Cleaners brush, emptying the dust bin after each cleaning session, cleaning or replacing the filter and wiping the sensors or cameras to make sure that your robot can see your home well for the next cleaning session.

It's not perfect. Our tester found it struggled to follow more specific commands. However, it works fine if you just set it to clean your whole space in the most thorough way possible, so if that's your main plan for it, then it's still a solid recommendation.

Another thing to consider is the cord length. Make sure to choose a model with a long enough cord so that you can move freely around your home while you're vacuuming.

Our testers like that it’s easy to remove hair from the iRobot’s signature dual green rubber brush rollers. iRobot vacuums have very good scores for data security, but like other models, its data privacy leaves a bit to be desired. iRobot Roomba Combo j5+
