I’ve been doing analysis on reddit data and was looking at the most recommended vacuum cleaners in r/VacuumCleaners VS other subs. Thought I’d share the results here.

Its part of a side project of mine to play with Reddit data and LLMs. The goal was to create something useful for the community while learning and improving my development skills.

The analysis aims to highlight the most well reviewed vacuum cleaners. It can be taken as a very rough proxy for what’s widely considered the best vacuum cleaners. Hopefully it is a useful data point for anyone overwhelmed by the massive amount of fragmented information out there.

Methodology: For extraction and sentiment analysis, I used the Reddit’s API to scour discussions on vacuum cleaners across all subreddits (filtered for the past year for freshness). I sampled 586 relevant threads and used LLMs to analyze, extract, and categorize opinions from the comments. To identify the product, I used the info in the comment to lookup Amazon. Unfortunately for now the list only shows models available on Amazon (for simplicity’s sake).

For ranking, I calculated the normalized difference and ratio between the no. of positive and negative user sentiments, and used that to determine the final score for ranking.

Caveat: Handling and merging different descriptions, model numbers, abbreviations etc, and associating them with the right variation is non trivial, so its not 100% accurate. Let me know if you spot anything wrong or surprising.

I just found this sub and am looking to purchase the best vacuum on the market. I have thousands to spend but want the best of the best, weather it's expensive or not, I don't care. I want carpets that look factory fresh everytime I clean the house.

Hit me with the best model and why.
