It is rare that objectionable reviewers would do that. Usually, in the interest of fairness and acting on the side of the rights of consumers, as well as acting independently and without any bias towards one manufacturer over others, professional or part-time online reviewers would, as a matter of course, give the full gamut of pros and cons on any particular product or service under review. The cons listed do not necessarily mean that any particular product or service should be avoided.
It is just a matter of routine of making consumers fully aware of all professional observations and critical concerns. But it is rare that only pros are listed while reviewing a sample of items to help determine what could be the best car vacuum on the market today. No one machine or make/model is mentioned here. But it is an indication of positives highlighted during the review process.
It cannot be said that each and every pro will be mentioned. Here, however, two are. A reviewer remarked that it is useful to have a stretch hose attached to the vacuum. You can see where this is leading to. It is able to reach every corner and crevice of the vehicle. Due to a lack of indoor shelter or garage space for many car owners, car vacuuming activities will be taking place outdoors. So, it also helps to have a long enough cord that can be rolled all the way to the nearest wall socket.
One machine found had a cord as long as twenty feet. One big plus well worth mentioning and thus qualifying the machine as a candidate to be among the best is the vacuum cleaner’s multiple use and/or multiple surface uses. Earlier, mention was made of fairness and the rights of the consumer. It would not be fair to pull the wool over the eyes of the consumer without mentioning at least some of the potential cons of some of the machines under review.
One con picked up was that a machine is too heavy. Given the car’s space restrictions, it would make far better sense to have a machine in use that is lightweight and portable and versatile. Easy to maneuver, in other words. This note closes off positively. Two separate motors on a single machine serve two separate functions; brushing and suction.
