If by suspension you mean the charging station for mounting on the wall, that is often a bit difficult with this type of battery hoover. I briefly looked at the manuals for both and no, both use a completely different charging system. There are manufacturers who always use the same concept for charging. For example, the Roidmi battery hoovers have a small round magnetic wall mount, from model S2 even with magnet and charging. The Xiaomi and Dreame battery hoovers come with identical wall charging stations that can even charge a second battery at the same time. Currently, the best battery hoover device in terms of price and performance would be the Xiaomi G10, which is available for about 260 Swiss francs. Maybe that is also an alternative? Because of the similarities between the two models, there would at least be a guarantee that the next generation, whether Dreame or Xiaomi, would use the same charging system.
