The
Dyson DC25 
is the most powerful of the "ball" vacuums. It is very smooth steering, lighter weight than other uprights and flexible to use on carpet or floors. They made (2) models of the Dyson Ball, but do not get confused. The DC 24 has
half the power of the
Dyson DC25 
model. The DC25 has a larger dirt cup and more "air watts". In fact, the DC24 has 115 "air watts" of power, while the larger, powerful DC25 has 220 "air watts" of power.
Maintaining either of the "ball" vacuums requires a few steps that you should know before you purchase one. This way, you will know exactly what to expect up front.
1. Filters. Yes, the filters are durable, and washable. But you MUST remember to wash them and if you do a lot of vacuuming, you will want to wash them more often than every six months, which is what Dyson suggests. There is a filter
INSIDE of the
Dyson DC25 
that needs cleaning so make sure you do not neglect it.
2. Dust cup cleanliness. The dust cup of the
Dyson DC25 
is the same as other models. The main consideration is to keep hair and debris out of the small holes that line the cyclone head. You can use a putty knife to remove any hair that clogs these holes. Do not get the cyclone head wet! Instead, if it is very dirty use a damp cloth to wipe off the fine dust. You can also use pressurized air to clean the cyclone head of dust.
3. WD-40. A bit of WD-40 may be needed occasionally as the
Dyson DC25 
can start to squeak over time.
Hinges and rubber gaskets. There is a rubber gasket that can become dusty over time. This is the part that joins the vacuum and the dust cup together. A little WD-40 can keep the seal from drying out over time. Also, the hinge that releases the dirt out the bottom of the cup can be lubricated.
4. Plastic cleanliness. A simple wipe down with a general cleaner can do the trick. make sure to wipe the area where the dust cup sets, so dust does not accumulate in or around any contact points. This will make everything fit correctly to maintain proper suction.
The
Dyson DC25 
has a 5 year warranty. This makes it a good choice since any defects are repaired or replaced by Dyson. Most vacuums are lucky to have a one year warranty!
So, if you follow my advice, you can keep your
Dyson DC25 running for a long time.
