Widest brush. Cheapest with good suction power on hard floor, but high follow-up costs for consumables. Cleans hard floors well of coarse dirt. On carpet weak at corners and edges, but with the best surface coverage. Hardly pollutes the air with dust when vacuuming, but is noisy on hard floors.

The systematic floor cleaning is this robot's greatest strength: at the end of the individual test phases, it has reached almost every spot on the floor in the test room. With the exception of the short instruction manual, the operation is also mostly easy. The suction performance, however, is sometimes only "satisfactory".

The most expensive vacuums are also the best: the Ecovacs, Roborock and iRobot devices for 700 euros make it onto the winner's podium. The test victory goes to Ecovacs: it navigates smartly and quickly through the rooms and collects the most dirt. It also scores with many functions and spirited wiping...

The vacuum robot with the unconventional design is not only well equipped, but also scores points with its extensive operating functions. The floor sweeper from California is laser-guided and climbs easily over small steps or carpet edges.

In comparison, the Botvac V7 Connected vacuum robot from Neato performs solidly. It excels in the categories of features and comfort. The navigation is also more than satisfactory. However, the device's suction performance is weak and at around 600 euros it is just about acceptable in terms of price-performance ratio.

The Neato Botvac D7 is a powerful but quiet robot vacuum cleaner that delivers a very good cleaning performance. The easy set-up and operation of the app, which offers many convenient functions, is pleasing.
