After >5 years with some old-style Siemens vacuum cleaner, I've now replaced it with a Dyson DC32.

Pros:

• The normal strainer is very effective, especially on carpets
• Bar/staff is rather flexible -> more freedom for cleaning under the bed
• Very long cable -> more freedom

Cons:

• Very loud
• Getting the bin clean afterwards is a bit challenging. Might not be a problem compared to normal vacuum cleaners though (which also tend to be full of dust after replacing the dustbag)
• Needs more stowing space
