This weekend, there are some great deals on things you want and need. Invest in a robot vacuum you can control from your phone or a portable Bluetooth speaker for summer fun and save some money in the process. There are a lot of sales on Amazon every day, but they're not always on things that are worth buying. So we scoured Amazon to find the best deals on products that are actually worth your time.

1. Under $200: One of the best affordable smart robot vacuums

A robot vacuum that costs less than $200 and has a smartphone app? Yup. It exists thanks to a sale that knocks $70 off the regular price. You just need to use the coupon code "CXC8LZ5M" at checkout to get a big discount on the Ecovacs Deebot N79S. To be honest, you're not going to get a fancy app experience (it's basically just a digital version of the remote). But you can still start a cleaning cycle when you're still working at the office, which seem pretty dang luxurious.

We tested the predecessor (the N79) and it did pretty well at picking up dirt and debris, but had a longer than average cleaning time and wasn't too great with getting up onto high-pile carpet. The N79S has improvements, but it also went a step further and now includes Amazon Alexa compatibility. Imagine being able to tell your virtual assistant to clean your home...and have it work? The future is here!

2. Under $60: Our favorite portable Bluetooth speaker

Summer is better with tunes, and right now our favorite portable Bluetooth speaker is back down to its lowest price. We love its sharp, clear sound that sounds great in the living room or in the backyard. It's got a 10-hour playback time, you can use it to answer the phone if you want, and if you get caught in the rain or splashed at the pool, the speaker will be fine.

Listen, Father's Day is a few weeks away. Instead of half-assing a gift for Dad this year, get him something memorable: a DNA testing kit. He can spit into a tube, wait a few weeks, and get all sorts of insights into your family's ancestry. 23andMe is one of the most popular kits out there, and right now you can save 30% and get it for $69 instead of $100. You might find some long-lost relatives or learn that you've got ancestors from a place you never knew about.

5. Under $40: A perfectly sized microSD card

Running out of space on your phone, your tablet, your camera, or your Nintendo Switch can be the worst. So if you've been struggling with data management on your devices, maybe it's time to invest in a microSD card. SanDisk is the top name in memory cards, and right now you can get the 128GB micro SDXC UHS-I card for nearly its lowest price.
