I opted for the most affordable model of this suction device. There aren't many nozzles available, and the cost of alternatives is high. Advantages that vary Most effective handheld vacuum cleaner. It does a much better job of vacuuming than my traditional vacuum. Easy to maintain and operate. Uses up hardly any room. Useful in a variety of settings. Some drawbacks The cost is prohibitive. The plastic has some streaks. Akin to splits. What a cast! Power storage ability. Maximum effectiveness is poor. It's unfortunate that these vacuums don't have the option to connect to the internet and function remotely.
