Price and load capacity compared

Among the 200 round vacuum lifters in this comparison, it ranks in the most expensive quarter. At 140 kg, its load capacity is 60 kg below the typical value for this design (200 kg). That works out at 144 kg of capacity per €100 spent; the median is 347 kg.

Drive and operation

The battery is built in. That saves weight and cost, but means a charging break when it runs flat. It charges via USB-C, so with the same cable and charger as your phone or laptop. Battery capacity is 2,000 mAh. A digital display shows the vacuum level and battery charge.

Seal and applications

The sealing lip is rubber. On smooth surfaces such as glass, polished tiles and stone it seals very tightly and lasts a long time; on rough or textured surfaces it is at a disadvantage. According to the data sheet it is suitable for tiles.
