Question: I have a terrible history with battery operated handhelds. How well has the battery performed over time?
Document: This vacuum is good deal. It is clean very well and the battery stay for long time. I used it for my car as will.
I do find the battery life to be the main problem - I keep it charged whenever it's not being used. I know this is probably bad for the rechargeable battery inside the unit but I really see no better alternative. Even if you discharge the battery completely and then recharge it for at least 18 hours as with the first-time charging, the battery life is still short, so might as well keep it on the charger.
I do not recommend this product. The suction is terrible! Do not buy it! It does so so on furniture but will not suck up on the floor very well.
This product should not even mention &#34;Pet Hair&#34; in the name. It doesn't work at all. We have a very fine microfiber couch and this did not work one bit. It is more efficient to pick the hairs up individually! Terrible suction - waste of money. Don't waste you time, buy a shop vac or a wet vac.
I do have an issue with the fact that it loses suction and requires constant emptying, hence the deduction of a star. But what are you going to do? This is a battery operated unit whose battery actually outlasts its suction performance. I could use this thing for 20 minutes, but at about 10 the suction is decreased to the point where you realize you just have to empty it. But, it works great for the spot cleaning for the dog hair that gets everywhere.
Because I haven't had a problem with it. ... And we use it everywhere... The battery life is good as well
Given the conveniences of a moderately lightweight, cordless, handheld vacuum, the Bissell is easy to recommend to any pet owner or those who hate having human hair all over their furniture. Although many full size vacuums come with attachments that aim to fill the same role as the Bissell Pet Hair Eraser, unless you are dragging out the big vacuum for a full cleaning, you'll be much happier with the time and energy saved by using this handheld vacuum.NOTES:  I will post here soon with battery life and charging time.
I like this cleaner. It is reasonably lightweight and appears to be well constructed of quality materials. It charges rapidly and the charger is well designed for either horizontal or vertical placement. The suction is among the best I've seen in a hand vacuum. Not as much suction as the Dyson handheld but nothing like the price, either. Battery life is ample for the jobs this device is intended to do. At the business end there is an extensible firm rubber tip with blunt teeth on it.
I have 2 cats and a golden retriever (lots of long hair!). Bissell Pet Hair Eraser works great with removing dog and cat hair from smooth surfaces such as leather, wood, glass furniture, but not well on fabrics/apolstered furniture. Battery life (charged as directed) last for one good sweep of the living room area and stairs, but I use it as a &#34;touch up&#34; and not as a replacement for my normal vacuum.
This is a great little vacuum. It has lots of power and the battery seems to last a long time.
Answer: I personally am very happy with this product.  None of these hand-held vacuum devices have extraordinary suction capability as they are meant for small clean-up jobs.  Having said that, the Bissell pet hair eraser does exactly what I need it to do......removes hair from furniture and pet beds as well as dust bunnies in room corners and cat litter trails.  I use mine daily and so far the suction and battery life have not failed me.  In addition, I'm one of those people who cleans the dust collection bin and filter each time I use it as that keeps the suction going good.  I also soak the filter in warm soapy water every month to clean it.  Eventually I'll buy a new filter but so far the soaking has worked well.  In my humble opinion, those people who give this product a negative review are not taking care of it properly and, therefore, it does not perform as they expect; or their performance expectations are too high for this type of device.
