We couldn't imagine there was much room to improve the Eufy RoboVac 11 when we selected it as our favorite budget robot vacuum. It was one of the simplest, smallest, and most affordable models available. The 11s has the same black finish and tempered-glass top as its predecessor, but it's slightly smaller: It's been scaled down to 12.8 inches in diameter and 2.8 inches in height from the 13-by-3-inch original. That's one of the slimmest profiles we've seen in a robot vacuum, rendering it it ideal for getting under low-clearance couches, coffee tables, and other furniture. Like the RoboVac 11, the new 11s doesn't use any sophisticated mapping technology to navigate.

Too lazy to get out of bed to turn the lights on or off? Have I got a light switch for you! At its simplest, Lutron's Caséta Dimmer is a four-button in-wall light switch with both on/off and dimmer controls built in. But the real fun comes in the form of a wireless remote control that offers the same functions and which you can put just about anywhere. Whether that means dimming the bedroom lights from under the covers or controlling an exterior light from the other side of the house, the Caséta remote is versatile and, throughout my testing, never missed a beat.
