We also had the Dyson animal for about 7 years and yes, ours also lost its suction over time. We just bought the new Professional Shark with a complete sealed HEPA filter and I adore it! It has adjustable suction for different surfaces and a ton of other cool features. Also (this is gross, sorry.) when we brought it home I had just vacuumed with our Dyson and when we tried out the Shark we filled up two canisters of dust and hair just downstairs! Ugh!!
