The stick vacuums popularized by Dyson and others are convenient and lightweight. But by design they don't have large dust containers, so must frequently be emptied. Some users find the emptying act, where you open the bin over a garbage can, unpleasant as it typically releases a poof of dust into the air.

Chinese electronics manufacturer Roborock has done away with this. Their H60 Hub Series features a prominent, tower-like charging dock.

Once you plug the vacuum into the dock, it automaticallly sucks the dust out of the vacuum and into the dock's integrated 2-liter dust bag. It takes about ten seconds, and the company claims the bag is good for 60 days' worth of vacuuming, though the actual figure surely depends on how dusty your house is.

Aside from the dock, Roborock's offering is similar to a Dyson: It's got the green dust-illuminating laser, nine cyclones, and filters you can wash at a sink.

Of course, this increase in convenience comes with trade-offs. The dock's prominent presence in the room might be unwelcome, and there's more stuff that can potentially break. It also requires buying Roborock's dust bags, which are $32 for a six-pack.

The H60 Hub Series runs $600.
