If your priority is size, though, this is a solid choice. Our reviewer felt it would be a great choice as an 'upstairs' robot vacuum, away from the tougher challenges of kitchens and living rooms.

For our straight-line pickup tests on hard flooring, we spread large and small debris within a marked area proportional to the width of each robot vacuum’s nozzle. Each robot vacuum is given 10 minutes to clean and the debris collected is weighed to determine how much was picked up.

And while removing dog hair on carpet wasn't as impressive, it still rated high in comparison to others that we've tested. What's more, we were impressed with its mopping results, and the self-cleaning doc was a bonus.

While the app is intuitive, and the mapping good, there is a major issue for anyone with an open plan living space. Namely, you can't separate it into different zones. It won't be a problem for everyone, but if you live in an open plan home, you'll probably want to opt for a different brand.

The brush roll is also easily detachable for quick maintenance and cleaning — and its "floating" design adjusts seamlessly to uneven surfaces.

However, with an average pick-up score of almost 97 percent, it's a capable vacuum on both hard floors and carpet.

How big is your home? If your robot vacuum will have a lot of ground to cover, look for a model with a long battery life and a large dust bin.

Though there are options that cost under $cem, we have never found a high-quality robot model in that price range, though there are plenty of other good inexpensive vacuums.

It’s also stellar at cleaning edges and corners, but our testers found it has a tendency to scatter debris. This affordable model has a lithium-ion battery and a one-sided brush, and it comes with an Em excesso filter, a filter cleaning tool, and a docking station.
