https://www.blackanddecker.com/products/bsv2020p I have hard floor with rugs everywhere and it works good, use medium or low suction on carpets. Clean the filter often, get 2-3 extra filters to rotate between. This is important to keep the suction at full strength. Replacement batteries are easy to find and will be for a long time because they use the same battery for a lot of tools. There's a similar one that's not "pet" branded, I think the pet one just has some rubber built in to the roller.
I’m late to the party, but my Black & Decker was less than $200 and works great for small spaces! [https://www.blackanddecker.com/products/bsv2020p?srsltid=AfmBOoqc8nso8gBeCrw7QDgMSI_wXn3nFBPzQ59o8low4j-BUDW2ibGq](https://www.blackanddecker.com/products/bsv2020p?srsltid=AfmBOoqc8nso8gBeCrw7QDgMSI_wXn3nFBPzQ59o8low4j-BUDW2ibGq) You will know when the filter needs to be changed when you lose suction. I just tap out the initial nasty stuff in the garbage and then beat the crap out of it in my kitchen sink, wash the stuff down the drain, rinse the filter as much as possible, and let it air dry before putting it back in the vacuum/using it again. I haven’t had to replace the filter in over a year with 2 Great Pyrenees and 3 cats.
If you're looking for a lightweight, stick, canister, rechargeable vacuum I can't say enough good things about the Black and Decker Powerseries Pro Pet Vacuum I got five years ago. It's not corded so it might not be be your main vacuum for a whole house but it's been great for day-to-day cleaning up after my pets. It has rubber bristles to grab all their fur and it takes less than a minute to pop the roller in and out to easily remove any tangled hair (which is mine, not theirs).
This right here. I have a Roomba that is programmed to sweep twice a week, a Black & Decker stick vac with removable and rechargeable battery for convenient clean ups, and a Miele bagged canister vac with the electric floor brush for weekly deep carpet and upholstery cleaning. I also have a Vapamore canister steam cleaner for bi-monthly tile floor cleaning.
I agree with this. For the cordless vacuum, do not cheap out as the battery is crap. I bought 40 sgd was nearly useless. Less than 10 mins suction time and battery died less than a year. I went for a black and decker with a replaceable battery. The battery used in their power tool systems, a bit bulkier but at least you can swap battery packs.
